The big secret of laying method of extruded board for roof insulation layer

Winter in northern cities is bitterly cold, but do you know? They have a secret weapon-the extruded board insulation layer on the roof. Want to know how this insulation layer is laid? Why can it be a weapon to keep out the cold?

Save materials, start with me!

Before construction, carefully plan the layout of extruded boards, so that each board can be fully utilized.

Horizontal laying and tight connection.

When laying, first lay horizontally to ensure that the plates are closely connected. The gap is less than 2mm, and the height difference is less than1.5 mm. When laying vertically, the staggered joints will be bonded, and the insulation effect can be achieved by going up a flight of stairs!

Heat insulation, against the cold.

The roof insulation extruded board is made of polystyrene resin and has a completely closed bubble structure, which seems to put a vacuum insulation coat on the house to keep out the cold and keep warm.

Protect your home from water and moisture.

Raw materials do not absorb water and the structure is closed. Even in rainy and humid weather, it can protect your home from moisture and make a comfortable life unaffected.

High strength compression, stable protection

After special treatment, it has high density and strong pressure resistance, which can protect your home steadily no matter what weather.

Flame retardant, corrosion resistant, multi-purpose.

Roof insulation extruded board also has the characteristics of flame retardant and corrosion resistance, which is not only suitable for roof insulation, but also can be used as waterproof and moisture-proof material for the ground, which is multi-purpose, affordable and convenient!
