Renovating a trapezoidal sheet metal roof with PUR roof spray foam (polyurethane foam) is an effective method to improve the insulation and waterproofing of an existing roof.

Specifically here, a polymer mesh with 5mm mesh was rolled out over the entire roof surface to level the roof surface.

Advantages of renovation with PUR roof spray foam:

Seamless sealing: The foam is applied seamlessly and thus reliably prevents water penetration.
High thermal insulation: PUR foam offers very good insulation values (λ value approx. 0.025–0.030 W/mK), which leads to energy savings.
Fast processing: The renovation can be completed in a short time – ideal for industrial halls and agricultural buildings.
Corrosion protection: The foam protects the underlying trapezoidal sheet from further corrosion.
Low additional weight: The roof load is hardly increased because PUR foam is very light.
