Thermal insulation boards PIR TechnoNIKOL- innovative thermal insulation for flat roofs, made on the basis of polyisocyanurate foam. PIR thermal insulation boards have a unique cell structure and are laminated on both sides with special aluminum foil. Thanks to closed system cells and coating from aluminum foil, plates PIR TechnoNIKOL absolutely waterproof, highly resistant to fire, resistant to repeated physical activity(from the passage of personnel) have a record low thermal conductivity coefficient. PIR thermal insulation boards retain their unique properties for at least 50 years.

Advantages of using roofing systems with PIR thermal insulation TechnoNIKOL:

• Decline design load on the supporting structure due to low density and reduced thickness of the thermal insulation layer.
• Guaranteed energy efficiency and durability:

  1. TechnoNIKOL PIR thermal insulation slabs retain their geometric dimensions throughout their entire service life - they do not sag under the influence of static and dynamic loads and do not shrink;
  2. TechnoNIKOL PIR thermal insulation boards have practically zero water absorption due to their closed cell structure: PIR has 95% closed pores with a very rigid fixed cell structure.

• Guaranteed waterproofing - thanks to a rigid and durable base:

  1. High compressive strength from 120 kPa
  2. After 30 load cycles, the strength does not lose more than 0.5%
  3. There is no risk of damage to the waterproofing by fasteners during operation.

• The low flammability of thermal insulation boards PIR (G1) allows roofing to be carried out on profiled steel decking of any area without additional protection from fire and does not require the installation of fireproof cuts. PIR thermal insulation boards do not support combustion, and also protect other layers of the system from the effects of fire.
• Minimum thermal insulation thickness due to high heat-saving ability of 0.024.
• Durability! TechnoNIKOL PIR thermal insulation slabs will perform their function throughout the service life of the building.

Thermal insulation slabs PIR TechnoNIKOL based on rigid polyisocyanurate foam
Thermal insulation boards PIR TechnoNIKOL today are the best solution for insulation of all types of structures during capital construction and reconstruction of residential, public and industrial buildings and structures. Plates PIR TechnoNIKOL combine the advantages of materials based on stone wool And extruded polystyrene foam while simultaneously eliminating their shortcomings.
For a visual representation of the greatest feasibility of using slabs PIR TechnoNIKOL , in comparison with thermal insulation materials based on stone wool, we propose to consider several standard options for organizing a thermal insulation layer in the structure of an unused roof.

Thermal insulation boards PIR TechnoNIKOL have excellent heat-saving properties exceeding competing materials by 40-110%. At the same time, the cost of both the material itself and installation work with subsequent operation significantly lower than competing thermal insulation materials

In countries Western Europe, USA, Japan have already appreciated the advantage of thermal insulation based on rigid polyisocyanurate foam. PIR's market share has already exceeded half of the entire market for thermal insulation materials in all areas of the construction industry and utilities. Today in Russia, PIR thermal insulation boards are a relatively new material. But their unique lightness, water resistance, practical non-flammability, ease of installation and operation have already made it possible to win 5% construction market. Such objects as the IKEA shopping center, the Paterson shopping center, the Airbus shopping center, the Union shopping center, the TOYOTA auto center, the Maryina Roshcha sports complex, the Luzhniki Fair, VNIIMETMASH, Liftstroy JSC and many others have already appreciated the benefits of thermal insulation based on rigid polyisocyanurate foam PIR.

On thermal insulation boards PIR TechnoNIKOL Technical solutions have been developed and a certificate of conformity, a SEZ certificate and a fire declaration have been obtained.

Advantages of slabs PIR TechnoNIKOL The lowest thermal conductivity coefficient on the market of thermal insulation materials - no more than 0.022 W/m*K Fire safety - PIR is a non-combustible material and does not spread fire flames. Flammability group G1 Lightness and strength with low material density: 35-40 kg/m 3 The low weight of PIR boards ensures convenient and simple installation. The rigid and elastic plate can be easily cut with a knife. The PIR board does not deform during operation. Resistance to aging, decomposition, microorganisms and aggressive environments - service life more than 50 years. Ecologically pure material- PIR boards are manufactured without the use of freons Minimum vapor permeability 0.006 mg/(m.h.Pa). Water absorption coefficient is less than 1%.

is a non-operating roof system based on a profiled steel sheet with a roofing carpet made of polymer membrane and thermal insulation boards made of polyisocyanurate foam (PIR).

The PIR-Roof Expert system is designed for roof insulation:

• industrial buildings (production workshops, warehouse complexes, etc.)
• public buildings and structures (shopping and office centers, sports facilities, shopping and entertainment complexes, etc.), flat roofs agricultural buildings
• with a lot of stuff placed on them technological equipment which requires regular maintenance.

In the PIR-Roofing System Expert as a layer of thermal insulation and a solid foundation under roof covering PIR-plate of the PirroMembrane brand is used, with stepped L-shaped profiling of the ends, laid in one or two layers with bandaging of the seams.

PirroMembrane is a thermal insulation board made of rigid polyisocyanurate foam (PIR) with a double-sided lining of 50 micron thick embossed aluminum foil. PirroMembrane PIR boards have high compressive strength and are resistant to concentrated loads that arise when both workers move across the roof during the construction phase and service personnel during operation. In this connection, the PIR-Roof Expert system provides an increased service life of the roof between repairs. The load-bearing base in the roof system is a profiled steel sheet, on which a vapor barrier made of polymer film or bituminous material.

The low thermal conductivity of PirroMembrane PIR boards ensures a reduction in the thickness of the system and a significant reduction in its overall weight, in contrast to traditional (fibre) insulation. Thus, the load on the building frame is significantly reduced, the metal consumption of the frame and, accordingly, its cost are reduced.

PIR board is resistant to water and water vapor: polyisocyanurate foam is not hygroscopic due to its closed-cell structure, and foil linings are the best barrier to water vapor. Thus, the slab does not lose strength over time and does not sag, providing comfortable conditions work.

PirroMembrane slabs have good fire-fighting characteristics - polyisocyanurate foam does not burn, but only chars on the surface, does not melt and does not form burning drops. This avoids the use of firebreaks on flat roofs over large areas.

Description of the structural layers in the roof system PIR-Roof Expert

To construct a vapor barrier layer, vapor barrier films based on polyethylene or bitumen-containing material up to 2 mm thick are used. The vapor barrier prevents the possible penetration of water vapor into the roofing pie through the joints of the slabs and abutments.

PIR-boards PirroMembrane have a low flammability group G1. Low group flammability of PIR-boards PirroMembrane provides the PIR-Roofing system with Expert class fire danger K0 (15) according to GOST 30403-96 and fire resistance limit RE 15 according to GOST 30247.0-94 and GOST 30247.1-94.

The deflection is performed on top of the main thermal insulation layer.

The PIR-Roofing Expert roof system includes polymer membranes based on PVC, TPO or EPDM, including PLASTFOIL® brands Classic, Polar, Eco, Lay, as well as membranes t.m. Fatra, Sika, Protan, CARLISLE, Decopran, etc. with fire hazard indicators G1/G2/RP1, which makes it possible to produce roofs without installing fire separation belts.

Why is it better to use PIR boards?

Using PIR PirroMembrane boards as thermal insulation material When insulating an unused roof with a polymer membrane, it has a number of advantages:

The PirroMembrane slab is the best solution for roofs in which the waterproofing material is laid directly on the insulation without screed. The strength of the insulation directly affects the durability of the roofing membrane and the tightness of the waterproofing layer. The compressive strength of PIR boards exceeds all values ​​for any fiber insulation.

Combination of materials: polymer membrane + PIR board provide minimum costs for maintenance of the roofing system and increase repair intervals.

Due to the low thermal conductivity of PIR boards, the thickness of the thermal insulation layer in the system is reduced by up to 80% compared to solutions based on mineral wool, which, together with the low density of PIR, leads to a reduction in the total weight of the PIR-Roof Expert roofing system in comparison with solutions with mineral wool.

The installation of the system is faster than traditional solutions:
- used for bending wedge slabs factory readiness;
- no time spent on laying a separating layer of fiberglass;
- thanks to the large area of ​​PIR plates and fewer attachment points, the thermal circuit is closed in a shorter time.

Polymer waterproofing materials allow you to reduce the time required to install a roof.

The PIR-Roof Expert system has high fire technical characteristics K0 (15) and RE15 and can be used in buildings of structural fire hazard class C0, having II-IV degree of fire resistance.

The procedure for carrying out work on insulating an unused roof with a polymer membrane

The PirroGroup company recommends using PIR-boards of the PirroMembrane brand as insulation under polymer membranes. They are designed specifically for the thermal insulation of flat roofs using soft polymer materials PVC type (as well as membranes based on EPDM and TPO).

For insulation, slabs measuring 1200x2400 mm and 1200x1200 mm with a stepped “quarter” profile are used. The slabs are attached to the base mechanically using disc-shaped dowels. The slabs of each subsequent layer are laid offset relative to the previous one, in a checkerboard pattern. When installing in two layers, the upper slabs are positioned so that their joints do not coincide with the joints of the lower slabs.

The membrane is installed from low to high areas of the roof. When laying the membrane, it is necessary to observe technological requirements overlapping panels

Production work is carried out according to the album technical solutions“Flat roofs with thermal insulation from PIRRO slabs based on polyisocyanurate foam (PIR) with soft cladding produced by PirroGroup (Russia) using polymer membranes”, “TECHNOLOGICAL MAP for installing a roof using the PIR-Roofing Expert system” and technical documentation on the use of polymer membranes.

The thermal insulation layer in the TN-ROOF Expert PIR system is made from PIR thermal insulation slabs with double-sided fiberglass laminated material, which are glued to the vapor barrier layer and also secured together using LOGICPIR adhesive foam. If it is necessary to make slopes and counter-slopes on the roof, use PIR SLOPE thermal insulation slabs. Waterproofing layer performed using a LOGICROOF V-GR FB polymer membrane with a fleece backing made of laminated geotextile, which is glued to the surface of the PIR boards using LOGICROOF Bond Contact Adhesive. The membrane is glued to PIR boards after preliminary foaming of the glue, which avoids its absorption into the fleece. The membrane panels are joined together using hot air, for which purpose a strip without a fleece backing is provided on the surface of the membrane.

According to the conclusion of the Federal State Budgetary Institution VNIIPO EMERCOM of Russia, the roof structure has a fire hazard class of K0 (45) and, depending on the parameters reinforced concrete slab fire resistance limit REI 30 - REI 90, which allows the system to be used as coatings in buildings and structures of any degree of fire resistance and with any class of structural fire hazard.
