Technological map for the Penoplex insulation device

Application area technological map on penoplex

The technical map was developed for a roof with a slope of less than 10% in relation to a one-story shop industrial building, the overall scheme of which is 72x24 m.

The composition of the work under consideration includes the laying of insulation boards on bitumen.

Organization and technology of the construction process

Before starting work on the thermal insulation device, the work on laying the profiled sheet must be completed.

For the device of thermal insulation, extruded polystyrene foam material "Penoplex" is used, laid on bitumen BN-90/10 GOST 6617-76. Plates Penoplex are certified in the systems of GOST R of the State Standard of Russia and Mosstroycertification and are approved for use as a heat and sound insulating material by the Sanitary and Epidemiological Conclusion of the Center for Sanitary and Epidemiological Supervision.

Plates "Penoplex" are delivered to the site to the mast lift. The supply of insulation boards to the roof is carried out by a mast cargo lift C-598A. The plates are transferred to the workplace manually.

Hot bitumen is prepared centrally and delivered to the construction site in asphalt distributors. The supply of bitumen to the coating is carried out by the SO-100A machine. The SO-100A machine is mounted on a trailer. The bitumen from the asphalt distributor is pumped into the SO-100A machine and fed through the pipeline to the coating. The pipeline on the vertical section is attached to the wall of the building with brackets with clamps, and on the inventory racks with a reverse slope of 0.01%.

Bitumen is delivered to the place of work in tanks filled to 3/4 of the volume, on a pneumatic wheeled trolley. The tank is filled from the dispensing points of the bitumen pipeline.

Slab heat-insulating foam boards are laid on the coating on bitumen with a snug fit to the vapor barrier layer.

Before starting work, the roofer checks the dryness of the base and installs beacons that allow the slabs to be laid in an even layer. For the production of works, the coating in the plan is divided into grips (9x12).

All work on the installation of Penoplex plates is carried out to meet the supply of materials. Before laying the slabs, hot bitumen (160-190) is applied to the surface of the coating in strips 100-120 mm wide every 150-200 mm. Bitumen is poured into buckets and leveled over the surface with brushes.

Thermal insulation boards must be laid from the top marks to the bottom, with the long side across the roof slope.

The joints of the slabs have a stepped shape, which provides a tight lock and allows you to lay the slabs with an overlap.

Grease the ends of the plates located at the edges of the coating with bitumen.

When storing and transporting thermal insulation boards, measures must be taken: the boards can be stored outdoors in their original packaging, but they must be protected from prolonged exposure to sunlight to prevent destruction of the top layer of the boards.

After performing thermal insulation during the day, it is necessary to cover the slabs with geotextile material, which will protect the slabs from ultraviolet sunlight, followed by covering it with gravel 5 cm thick.

Thermal insulation device winter period in accordance with SNiP III-20-74*, it is allowed at an outside air temperature of at least -20 ° С.

It is forbidden to lay the slabs on surfaces that have not been cleared of frost, snow and ice.

To protect the bases from damage when moving people, a wooden flooring is arranged on the surface.

Calculation Nº1: the number of lifts of insulation boards "Penoplex" mast lift:

The size of the Penoplex plates is 2250x1500x30 mm;

Consumption of plates "Penoplex" - (72x24) / (2.25x1.5) = 512 pcs;

The lift lifts 29 plates;

Number of lifts 512/29=18.

Calculation Nº2: Norm of time for bitumen supply using the SO-100A machine:

Meter - 1 m³ of bitumen;

The amount of bitumen per coating is 2 tons or 1.82 m³;

Machine productivity - 6 m³;

The composition of the link: driver 3 rubles - 1 person, thermal insulator 2 rubles - 1 person.

Norm of time for the meter: man-hour.

The walls of houses built of bricks, various wall blocks, and even more so - representing a reinforced concrete structure, in most cases do not meet the requirements for regulatory thermal insulation. In a word, such houses need additional insulation to prevent significant heat loss through the building envelope.

There are many different approaches to . But if the owners prefer the exterior finish of their house, made of decorative plaster, in a “pure” form or with the use of facade paints, then the best choice is the wet facade insulation technology. In this publication, it will be considered how difficult such work is, what is required to carry it out, and how all this can be done on our own.

What is meant by "wet facade" insulation system?

First of all, it is necessary to understand the terminology - what is the “wet facade” technology, and how does it differ from, say, ordinary wall cladding with insulating materials with further decorative sheathing with wall panels (siding, block house, etc.)

The clue lies in the name itself - all stages of work are carried out using building compounds and solutions that are diluted with water. The final stage is the plastering of already insulated walls, so that the thermally insulated walls become completely indistinguishable from ordinary, covered decorative plaster. As a result, two most important tasks are solved at once - ensuring reliable insulation of wall structures and high-quality facade design.

An approximate scheme of insulation using the "wet facade" technology is shown in the figure:

Schematic diagram of insulation using the "wet facade" technology

1 - insulated facade wall of the building.

2 - a layer of building adhesive mixture.

3 - insulation boards of synthetic (of one type or another) or mineral (basalt wool) origin.

4 - additional mechanical fastening of the thermal insulation layer - dowel-"fungus".

5 - protective and leveling plaster layer, mesh reinforced(pos. 6).

Such a system of complete thermal insulation and facade finishing has a number of significant advantages:

It does not require a very material-intensive installation of a frame structure.
The system is quite easy. And it can be successfully used on most facade walls.
The frameless system predetermines and practically complete absence"cold bridges" - the insulation layer is monolithic over the entire surface of the facade.
Facade walls receive, in addition to insulation, an excellent soundproof barrier, which helps to reduce both airborne and impact noise.
With the correct calculation of the insulation layer, the “dew point” is completely removed from the wall structure and taken out. It excludes the possibility of wetting the wall and the appearance of colonies of mold or fungus in it.
The outer plaster layer is characterized by good resistance to mechanical stress, to atmospheric action.
In principle, the technology is simple, and with strict adherence to the rules, any homeowner can handle it.

With high-quality performance of work, such an insulated facade will not require repairs for at least 20 years. However, if there is a desire to update the finish, then this can be easily done without violating the integrity of the thermal insulation structure.

The disadvantages of this method of insulation include:

Seasonality of work - they can only be carried out at positive (at least + 5 ° C) temperatures, and in stable good weather. It is undesirable to carry out work in windy weather, at too high (over + 30 ° C) air temperatures, on the sunny side without providing protection from direct rays.
Increased demands on the high quality of materials, and on the exact observance of technological recommendations. Violation of the rules makes the system very vulnerable to cracking or even detachment of large fragments of insulation and trim.

As a heater, as already mentioned, mineral wool or expanded polystyrene can be used. Both materials have their advantages and disadvantages, but still, for a “wet facade”, high-quality mineral wool looks preferable. With approximately equal values of thermal conductivity, mineral wool has a significant advantage - vapor permeability. Excess free moisture will find its way out of the premises through the wall structure and evaporate into the atmosphere. It is more difficult with expanded polystyrene - its vapor permeability is low, and in some types it generally tends to zero. Thus, the accumulation of moisture between the wall material and the insulation layer is not excluded. This is not good in itself, but at abnormally low winter temperatures, cracking and even “shooting off” of large areas of insulation along with finishing layers occur.

There are special topics for expanded polystyrene - with a perforated structure, in which this issue is resolved to a certain extent. But basalt wool has another important advantage - absolute incombustibility, which polystyrene foam cannot boast of in any way. And for facade walls, this is a serious issue. And this article will consider best option– “wet facade” insulation technology using mineral wool.

How to choose a heater?

Which mineral wool is suitable for a "wet facade"?

As is already clear from circuit diagram"wet facade", the insulation must, on one side, be mounted on an adhesive solution, and on the other, it must withstand a considerable load of the plaster layer. Thus, thermal insulation boards must meet certain requirements in terms of density, in terms of the ability to withstand loads - both for crushing (compression) and for breaking their fiber structure (stratification).

Naturally, not any insulation that belongs to the category of mineral wool is suitable for these purposes. Glass wool and slag wool are completely excluded. Only slabs of basalt fibers produced using a special technology are applicable - with increased rigidity and density of the material.

Leading manufacturers of insulation based on basalt fibers in their product line provide for the production of plates specially designed for thermal insulation of walls with subsequent finishing with plaster, that is, for a “wet facade”. The characteristics of several of the most popular types are shown in the table below:

- plate thickness	25, 30 to 180	from 40 to 160	from 40 to 200	from 40 to 150

Experimenting with lighter and cheaper types of basalt wool is not worth it, since such a “wet facade” will probably not last long.

How to determine the required thickness of insulation?

As can be seen from the table, manufacturers offer a wide range of insulation thicknesses for the "wet facade", from 25 to 200 mm, usually in 10 mm increments.

What thickness to choose? This is by no means an idle question, since the “wet facade” system being created should provide high-quality thermal insulation of the walls. At the same time, excessive thickness is an extra cost, and in addition, excessive insulation can even be harmful in terms of maintaining an optimal temperature and humidity balance.

Usually, specialists calculate the optimal thickness of insulation. But it is quite possible to do this yourself, using the calculation algorithm presented below.

So, the insulated wall must have a total resistance to heat transfer not lower than the standard value determined for the given region. This parameter is tabular, it is in reference books, known in local construction companies, and in addition, for convenience, you can use the map-diagram below.

A wall is a multilayer structure, each layer of which has its own thermophysical characteristics. If the thickness and material of each layer, already existing or planned (the wall itself, internal and exterior finish etc.), then it is easy to calculate their total resistance, compare with the normative value in order to get the difference that needs to be “covered” by additional thermal insulation.

It will not bore the reader with formulas, but we will immediately suggest using a calculation calculator that will quickly and with a minimum error calculate the required thickness of insulation with basalt wool intended for facade work.

Calculator for calculating the thickness of the insulation of the "wet facade" system

The calculation is carried out in the following sequence:

Determine the normalized value of heat transfer resistance for walls from the map-scheme for your region (purple numbers).
Specify the material of the wall itself and its thickness.
Decide on the thickness and material interior decoration walls.

The thickness of the external plaster finish of the walls is already taken into account in the calculator, and it will not be required to make it.

Enter the requested values and get the result. It can be rounded up to the standard thickness of manufactured insulation boards.

If a negative value is suddenly obtained, wall insulation is not required.

3 ORGANIZATION AND TECHNOLOGY OF WORK PERFORMANCE

PREPARATORY WORK

3.1 Prior to the start of installation work on the installation of a ventilated facade of the FS-300 system, the following preparatory work must be carried out:

Rice. 2. Scheme of organization of the construction site

1 - fencing of the construction site; 2 - workshop; 3 - material and technical warehouse; 4 - work zone; 5 - the boundary of the zone dangerous for finding people during the operation of facade lifts; 6 - open storage area for building structures and materials; 7 - lighting mast; 8 - facade lift

Inventory mobile buildings are installed at the construction site: an unheated logistics warehouse for storing elements of a ventilated facade (composite sheets or panels ready for installation, insulation, vapor-permeable film, structural elements load-bearing frame) and a workshop - for the manufacture of cladding panels and framing the completion of facade cladding in construction conditions;

They inspect and assess the technical condition of facade lifts, mechanization tools, tools, their completeness and readiness for work;

In accordance with the project for the production of works, facade lifts are installed on the building and put into operation in accordance with the Operation Manual (3851B.00.00.000 RE);

On the wall of the building mark the location of the beacon anchor points for the installation of load-bearing and support brackets.

3.2 Facing composite material is delivered to the construction site, as a rule, in the form of sheets cut to the design dimensions. In this case, in the workshop on the construction site, with the help of hand tools, blind rivets and cassette assembly elements, facing panels are formed with fasteners.

3.3 It is necessary to store sheets of composite material at the construction site on beams up to 10 cm thick laid on a flat place, in 0.5 m increments. The height of the stack of sheets should not exceed 1 m.

Lifting operations with packed sheets of composite material should be performed using textile tape slings (TU 3150-010-16979227) or other slings that prevent injury to the sheets.

Do not store the cladding composite material together with aggressive chemicals.

3.4 In the event that a facing composite material arrives at the construction site in the form of finished facing panels with fastening, they are placed in a pack in pairs, front surfaces to each other so that adjacent pairs are in contact with the rear sides. Packs are placed on wooden linings, with a slight slope from the vertical. The panels are laid in two rows in height.

3.5 The marking of the installation points of the bearing and supporting brackets on the wall of the building is carried out in accordance with the technical documentation for the project for the installation of a ventilated facade.

At the initial stage, the beacon lines for marking the facade are determined - the lower horizontal line of the installation points of the brackets and the two vertical lines extreme along the facade of the building.

The extreme points of the horizontal line are determined using a level and marked with indelible paint. At the two extreme points, using a laser level and a tape measure, all intermediate points for installing the brackets are determined and marked with paint.

With the help of plumb lines lowered from the parapet of the building, vertical lines are determined at the extreme points of the horizontal line.

Using facade lifts, mark with indelible paint the installation points of the bearing and support brackets on the extreme vertical lines.

MAIN WORKS

3.6 When organizing the production of installation work, the area of \u200b\u200bthe facade of the building is divided into vertical grips, within which work is performed by different parts of the installers from the first or second facade lifts (Fig.). The width of the vertical grip is equal to the length of the working deck of the facade lift cradle (4 m), and the length of the vertical grip is equal to the working height of the building. The first and second units of installers working on the 1st facade lift, alternating in shifts, carry out sequential installation work on the 1st, 3rd and 5th vertical grips. The third and fourth units of installers working on the 2nd facade lift, alternating in shifts, carry out sequential installation work on the 2nd and 4th vertical grips. The direction of work is from the basement of the building up to the parapet.

3.7 For the installation of a ventilated facade by one link of workers from two installers, a replaceable grip equal to 4 m 2 of the facade is determined.

3.8 Installation of a ventilated facade starts from the basement of the building on the 1st and 2nd vertical grips simultaneously. Within the vertical grip, installation is carried out in the following technological sequence:

Marking the points of installation of bearing and support brackets on the wall of the building;

Fastening sliding brackets to guide profiles;

Installation of ventilated facade cladding elements to the outer corner of the building.

3.9 Installation of the frame of the facade cladding of the plinth is carried out without using a facade lift from the ground (with a plinth height of up to 1 m). The parapet tide is mounted from the roof of the building at the final stage of each vertical grip.

3.10 The installation points of the bearing and support brackets on the vertical grip are marked using beacon points marked on the extreme horizontal and vertical lines (see), using a tape measure, a level and a dyeing cord.

When marking the anchoring points for the installation of bearing and supporting brackets for the subsequent vertical grip, beacons serve as the points of attachment of the bearing and supporting brackets of the previous vertical grip.

3.11 For fastening to the wall of the bearing and supporting brackets, holes are drilled at the marked points, the diameter and depth corresponding to the anchor dowels, which have been tested for strength for this type of wall fencing.

If a hole is drilled in the wrong place by mistake and a new one needs to be drilled, then the latter must be at least one depth away from the wrong one. drilled hole. If it is impossible to fulfill given condition You can use the method of fastening the brackets shown in Fig. 4.

Holes are cleaned from drilling waste (dust) with compressed air.

Rice. 4. Mounting unit for supporting (supporting) brackets if it is impossible to attach them to the wall at the design drilling points

The dowel is inserted into the prepared hole and knocked out with a mounting hammer.

Thermal insulation pads are placed under the brackets to level the working surface and eliminate "cold bridges".

The brackets are fastened to the wall with screws using an electric drill with adjustable speed and appropriate screwing nozzles.

3.12 The device for thermal insulation and wind protection consists of the following operations:

Hanging on the wall through the slots for the brackets of the insulation boards;

Hanging on the heat-insulating plates of the panels of the wind-hydroprotective membrane with an overlap of 100 mm and their temporary fixing;

Drilling through the insulation and the wind and hydroprotective membrane of holes in the wall for dish-shaped dowels in full according to the project and installing the dowels.

The distance from the dowels to the edges of the heat-insulating plate must be at least 50 mm.

The installation of heat-insulating plates starts from the bottom row, which are installed on the starting perforated profile or plinth and mounted from the bottom up.

The plates are hung in a checkerboard pattern horizontally next to each other in such a way that there are no through gaps between the plates. Permissible size of an unfilled seam - 2 mm.

Additional heat-insulating plates must be securely fixed to the wall surface.

To install additional thermal insulation boards, they must be cut with a hand tool. Breaking the insulation boards is prohibited.

During installation, transportation and storage, thermal insulation boards must be protected from moisture, contamination and mechanical damage.

Before starting the installation of heat-insulating plates, the removable grip on which the work will be carried out must be protected from atmospheric moisture.

3.13 Adjusting carrier and support brackets are attached to the carrier and support brackets, respectively. The position of these brackets is adjusted in such a way as to ensure the vertical alignment of the deviation of the wall irregularities. The brackets are fixed with bolts with special stainless steel washers.

3.14 Fastening to the adjusting brackets of the vertical guide profiles is carried out in the following sequence. The profiles are installed in the grooves of the regulating bearing and support brackets. Then the profiles are fixed with rivets to the bearing brackets. In the supporting adjusting brackets, the profile is installed freely, which ensures its free vertical movement to compensate for temperature deformations.

In the vertical joints of two successive profiles, to compensate for thermal deformations, it is recommended to maintain a gap of 8 to 10 mm.

3.15 When connecting to the plinth, the perforated flashing is fastened with a corner to the vertical guide profiles using blind rivets (Fig.).

3.16 Installation of cladding panels starts from the bottom row and leads from the bottom up (Fig. ).

Sliding brackets (9) are installed on the vertical guide profiles (4). The upper sliding bracket is set to the design position (fixed with the set screw 10), and the lower one - to the intermediate one (9). The panel is put on the upper sliding brackets and by moving the lower sliding brackets it is installed “into the spacer”. The upper sliding brackets of the panel are additionally fixed with self-tapping screws from vertical shift. From the horizontal shift, the panels are also additionally attached to the supporting profile with rivets (11).

3.17 When installing cladding panels at the junction of vertical guides (bearing profiles) (Fig. ), two conditions must be observed: the top cladding panel must close the gap between the bearing profiles; the design value of the gap between the lower and upper facing panels must be exactly maintained. To fulfill the second condition, it is recommended to use a template made of a wooden square bar. The length of the bar is equal to the width of the cladding panel, and the edges are equal to the design value of the gap between the lower and upper cladding panels.
