Polyurethane Foam Board with Aluminum Foil
Polyurethane Foam Board consist of Polyurethane (PU) foam core, with a facing material of 80micron aluminum foil or fiberglass tissue laminated onto one or both sides. This aluminum foil acts as a barrier to moisture and enhances the PU insulation properties of the board. The standard width of Polyurethane Insulation Board is 1200mm or 600mm. The PU Board thickness and facing materials can be changed as per different application or project specifications. Polyurethane Board with aluminum foil surface has their excellent thermal performance, moisture and vapor barrier properties, durability, ease of installation, and environmental friendliness.

Advantages of Polyurethane Foam Board with Aluminum Foil
01 / Excellent Thermal Performance: Aluminum foil has high reflectivity, effectively reducing heat conduction and radiation, enhancing insulation efficiency.
02 / Moisture and Vapor Barrier: Aluminum foil acts as a barrier against moisture and gas permeation, improving the insulation board’s moisture resistance and maintaining interior dryness.
03 / Durability: Aluminum foil is corrosion-resistant and weather-resistant, extending the insulation board’s lifespan by minimizing environmental impacts.
04 / Ease of Installation: Polyurethane Insulation Boards with aluminum foil surface are typically lightweight and flexible, easy to cut and install, reducing construction costs and time.
Why Choose GFI Polyurethane Foam Board?
01 / Low Thermal Conductivity and Excellent Thermal Performance: Rigid Polyurethane (PU) has a low thermal conductivity and superior thermal performance. When the density of rigid Polyurethane 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 Polyurethane 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, Polyurethane 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 Polyurethane burns, a carbonaceous layer forms on the foam surface, helping to isolate the underlying foam and effectively preventing the spread of flames. Polyurethane also does not produce harmful gases at high temperatures.
04 / Stable Pore Structure: PU insulation has 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 rigid PU insulation 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: Polyurethane 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 polyurethane insulation board, 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 Polyurethane 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 PU Insulation Board
1.Wall Insulation Systems
- External Thermal Insulation Composite Systems (ETICS) : Recticel PU 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 : PU foam insulation board 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, PU 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 : Polyurethane 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 polyurethane 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 polyurethane insulation board did not burn through and did not drip water. Prevent flame spread and heat conduction, no burning phenomenon.
