The SPRING of passive house technology!
Passive house refers to the adoption of sealed structural measures for buildings as a whole, so
as to minimize the dependence of buildings on traditional heating and air conditioning systems.
A retaining wall of passive building should meet the heat transfer coefficient of K = 1.5W/ (M2 (K)
when the shape coefficient is less than or equal to 0.4 when), polyurethane insulation layer
can choose the cost structure and the maintenance area of developers reduced.

ADVANTAGE
Polyurethane insulation material has excellent thermal insulation performance, and can meet different flame retardant grade requirements through formula adjustment. Its continuous dense insulation layer is especially suitable for roof insulation and waterproof integrated application, roof spraying and wall insulation.
PROCESS
Mainly for the spray, pouring and discontinuous production of block foam
TECHNOLOGY
According with international typical standards.
