Building Materials Lightweight Thermal Insulation Roof Corrugated Board Design Double Aluminum Insulation Board
Double aluminum heat insulation board is a heat insulation and fireproof material launched by our company for sun room, mobile board house, villa, pavilion, fire door and other products. The upper and lower layers of the product are all aluminum-magnesium-manganese alloy plates, and the middle is filled with high-density hard foam polyurethane as the core material. It is heat-insulating, heat-preserving, fire-proof, sound-proof, and has good air tightness, so that your sun room can easily say goodbye to the "steamer" in summer and the "ice cellar" in winter, and achieve true warm in winter and cool in summer.

Top 10 Product Features
1. Heat insulation
The core material of this product is made of hard polyurethane, which is an excellent thermal insulation material. Its thermal conductivity is between 0.015-0.025W/(m.k);
2.High compressive strength
The upper and lower layers of this product are made of a whole sheet of aluminum-magnesium-manganese alloy plate with a thickness of 1.0mm, and the middle adhesive core material has a closed-pore rate of more than 97% of high-density hard polyurethane. The load capacity of the whole board is more than 200 kg;
3.Fire retardant and high temperature resistant
The core material of this product is a flame-retardant self-extinguishing material, which will extinguish itself when away from fire, and the surface will be carbonized, which can prevent combustion and will not produce molten droplets;
4.Moisture-proof and waterproof
The upper and lower layers of this product are made of a whole sheet of aluminum-magnesium-manganese alloy plate to prevent penetration. The core material hard polyurethane is essentially a hydrophobic material and will not absorb moisture;
5.Stable performance
The aluminum-magnesium-manganese alloy surface of this product adopts fluorocarbon spraying or wood grain transfer technology, which is acid-resistant, alkali-resistant, anti-corrosive and rust-resistant. The core material is also an inert material that will not react with acids and alkalis, and is not a food source for insects and rodents, which can keep the material and thermal insulation performance constant;
6.Airtight sound insulation
This product has good sound absorption and can reduce the sound caused by the impact of rain, hail, etc.
7.Quick construction
This product is designed to be easy to install, fast, efficient, time-saving, labor-saving and material-saving;
8.Beautiful and elegant
This product has various surface forms and rich colors;
9.Super long service life
This product generally has a service life of 30 years, and it can be guaranteed not to be damaged even under the influence of various adverse factors;
10.Energy saving and environmental protection
This product is a new green environmentally friendly product, energy-saving and efficiency-enhancing, non-toxic and harmless.
