PIR Thermal Insulation Board with Kraft Paper
PIR Thermal Insulation Board consists of PIR Foam core, faced on both sides with 200micron kraft paper. The standard width of PIR Foam Insulation Board is 1200mm or 600mm. The length can be customized. The PIR Rigid Insulation Board with a kraft paper surface are a type of advanced insulation material that combines the superior thermal properties of polyisocyanurate foam with the durability and versatility of kraft paper. These PIR Insulation Boards offer a robust, versatile, and highly efficient solution for a wide range of insulation needs.

Why Choose GFI PIR Thermal Insulation Board?
01 / Low Thermal Conductivity and Excellent Thermal Performance: PIR Foam Board has a low thermal conductivity and superior thermal performance. When the density of rigid Polyisocyanurate is 35-40 kg/m3, its thermal conductivity is only 0.018-0.024 W/(m·K), which is about half that of EPS (expanded polystyrene). It has the lowest thermal conductivity among all insulation materials.
02 / Moisture and Water Resistance: Rigid PIR Foam Board has a closed-cell rate of over 90%, making it a hydrophobic material. It does not increase in thermal conductivity due to moisture absorption, and walls do not seep water.
03 / Fire Resistance, Flame Retardancy, and High-Temperature Tolerance: When flame retardants are added, Polyisocyanurate becomes a self-extinguishing material that is difficult to ignite. Its softening point can exceed 250°C, and it only decomposes at very high temperatures. Additionally, when Polyisocyanurate burns, a carbonaceous layer forms on the foam surface, helping to isolate the underlying foam and effectively preventing the spread of flames. Polyisocyanurate also does not produce harmful gases at high temperatures.
04 / Stable Pore Structure: Polyisocyanurate materials have a stable pore structure, predominantly closed-cell, which not only provides excellent insulation performance but also good freeze-thaw resistance and sound absorption. The average lifespan of PIR Rigid Insulation Board structures can reach over 30 years under normal use and maintenance conditions. They are not damaged by external factors such as drying, moisture, electrochemical corrosion, insect, fungus, or algae growth, or by rodent damage.
05 / Strong Deformation Resistance: PIR Foam Insulation Boards have strong deformation resistance, are not prone to cracking, and provide stable and safe finishes.
06 / Space Efficiency: Due to the excellent insulation performance of PIR Insulation Boards, the thickness of the building’s envelope can be reduced while still meeting the same insulation requirements, thus increasing the interior usable space.
07 / Environmental protection and energy saving: Fluorine-free foaming, no harmful substances prohibited or restricted by the state. Environment-friendly.
08 / High Cost-Effectiveness: Although the unit price of PIR Foam Board is higher than that of traditional insulation materials, the additional costs are offset by significant reductions in heating and cooling expenses.
Application of PIR Foam Board Insulation
1.Wall Insulation Systems
- External Thermal Insulation Composite Systems (ETICS) : PIR Polyisocyanurate Insulation Boards serve as the primary insulation layer installed on the exterior walls of buildings, providing thermal insulation and reducing heat transfer through the walls.
- Internal Wall Insulation Systems : Used for insulating the internal walls of buildings, particularly suitable for retrofitting old buildings for energy efficiency without affecting the exterior appearance.
2.Roof Insulation
- Flat Roof Insulation : PIR Insulation Boards can be directly laid on flat roofs, creating a continuous insulation layer to prevent heat loss through the roof.
- Pitched Roof Insulation : Suitable for various forms of pitched roofs, easy to install, and enhances overall insulation performance.
3.Floor Insulation
- Underfloor Heating Systems : In underfloor heating systems, PIR Rigid Insulation Board effectively reduce downward heat loss, improving the energy efficiency of the heating system.
- General Floor Insulation : Used in regular floor structures to enhance insulation performance and improve indoor comfort.
4.Curtain Wall Insulation
- Glass Curtain Wall Insulation : PIR Foam Insulation Boards can be used as insulation material in glass curtain wall systems, improving the thermal insulation performance of the curtain wall and reducing energy loss.
Buring Comparison Test
The following pictures show the state of the RLB-l Polyisocyanurate insulation fireproof composite board under the direct combustion of the 1300℃ flame torch for each period of time. During the entire experiment, the RLB-I PIR Insulation Board did not burn through and did not drip water. Prevent flame spread and heat conduction, no burning phenomenon.
