Exterior wall insulation material 1 * 40HQ glass wool blanket with aluminum foil "usually refers to a glass wool roll felt with aluminum foil veneer shipped in a 40 foot high cabinet (40HQ) with a specification of 1 meter wide. This material is widely used in the field of building exterior wall insulation, and its core advantage lies in the complementary performance of glass wool and aluminum foil veneers. The glass wool blanket with aluminum foil can achieve the three in one effect of "insulation+moisture-proof+fireproof" in external wall insulation. It is made of high-density glass wool and aluminum foil veneer composite, especially suitable for light steel keel exterior walls, steel structure buildings, and composite wall systems.
                                                                  

Glass wool blanket with aluminum foil functional effect:

1. Double insulation, energy-saving and consumption reducing
2. Moisture proof and vapor proof, protecting the wall
3. A1 level fire protection, intrinsic safety
4. Sound absorption and noise reduction to enhance comfort
5. Convenient construction, green and environmentally friendly


Construction and installation specifications for glass wool blanket with aluminum foil:
  • Aluminum foil orientation: During construction, the aluminum foil veneer must face the high-temperature side (i.e. the indoor side) to achieve optimal heat reflection and block indoor moisture.
  • Splicing and sealing: When laying, it is necessary to ensure that the rolls are tightly aligned, the longitudinal and transverse seams are staggered, and the gap should be controlled within 5mm. The joint must be sealed with specialized aluminum foil tape, and the recommended overlap width is ≥ 50mm to prevent thermal bridging effect and air convection.
  • Fixed method: Special insulation nails are usually used for fixation to ensure that the insulation layer is firmly attached to the wall, preventing material sagging or falling off due to gravity or wind.
  • Continuity and special part treatment: The insulation layer of through wall pipelines and other parts should be kept continuous and uninterrupted to avoid local heat loss.
                                                                    
The glass wool blanket with aluminum foil is made of high-quality centrifugal glass wool as the substrate, with high reflective aluminum foil attached on one or both sides. The thermal conductivity is as low as 0.033-0.040W/(m · K), and it is Class A non combustible with a water repellency rate of ≥ 98%. The aluminum foil layer reflects over 90% of the radiated heat, forming a dual insulation mechanism of "blocking heat conduction+reflecting heat radiation". The comprehensive energy-saving effect is 15% -20% higher than that of ordinary glass wool, making it the preferred material for steel structure factories, light steel keel exterior walls, and building enclosures.
