Polyurethane great wall panel(Thickening type)

Polyurethane Great Wall Panel, which can also be called Great Wall Thermal Insulation Aluminum Panel, Great Wall Thermal Insulation Panel, Thermal Insulation Great Wall Panel and so on, is a new type of green energy-saving, thermal insulation and fireproof building material integrating centralized aesthetics and modern industrial architectural design. It is made of double-sided aluminum-magnesium-manganese surface layer + polyurethane core layer composite. Polyurethane Great Wall Panel is often used in the roofing construction of sunroom, canopy, connecting porch, self-built house, Chinese pavilion and so on. The following is a detailed introduction of the evolution of polyurethane panels, parameters of the panels, installation of the overlap, advantages and selling points, application areas, production process and other aspects of the polyurethane panels.

Type And Parameters

Installation Overlap

1. Hidden nail type: first hit the nail to fix the notch end on the purlin, and fasten the other board; open nail type: after fastening the two boards, hit the nail on the purlin at the lap, and apply sealant or waterproof top cap.
2. Install inner and outer ridge cover tile.
3. Install sealing plug.
4. Install hill wall sealing piece.

Product Advantages

● Fireproof and flame retardant

The Great Wall heat-insulating aluminum panels are filled with high-density pentane system environmentally friendly rigid polyurethane in the middle, and the fireproof grade of polyurethane is B. After burning, it will form a coking protective layer, with no curling and no dripping material.

● Thermal insulation

Polyurethane has excellent thermal insulation performance and is one of the most excellent thermal insulation materials in the world. The thermal conductivity is 0.018~0.024w/m-k, and the thermal insulation performance of 3cm thick polyurethane board ≈ 24cm brick wall.

● Anti-mold and moisture-proof

Double-sided aluminum-magnesium-manganese plate is anticorrosive and rust-proof, with a service life of more than 50 years. Polyurethane rigid foam airtightness is excellent, water closure rate can reach 97%. Excellent antioxidant performance to prevent mold growth, plus the unique hidden nail design more isolated from rainwater intrusion.

● Sound insulation and noise reduction

Traditional veneer roofing panels are often noisy in rainy and snowy weather. Compared with traditional veneer roofing boards, the Great Wall Board can effectively reduce the noise impact of rain, hail and other indoor noise.

● Aesthetically pleasing

Combining Chinese aesthetics and modern industrial architectural design, the Great Wall panel's rustic colors and minimalist lines, combined with the strong metallic texture of aluminum, make the building's roof aesthetically pleasing and distinctive.

● Convenient construction

With an effective width of 950mm, one large sheet can be spread over several square meters. The design of the lap joint is simple, and the installation can be completed easily with only one lap and one buckle, which greatly reduces the installation period.

● Other advantages

The snap design of the lap joints eliminates the stubborn problem of deformation of the lap joint longwall boards, and the snap installation can be locked to form a tightly connected whole of the roof, which has outstanding wind resistance.

Application

Polyurethane Great Wall Panel is widely used: Chinese pavilion, antique building, sunroom, canopy, corridor, self-built house, villa, lodging, integrated house, industrial plant and so on.
