SWD 250 spray polyurethane foam
Excellent waterproofing performance
low water absorption performance low thermal conductivity, which is the 1/2 of glass fiber, 1/8 of perlite, 1/10 of vermiculite. Compared with traditional materials in the same performance demand, it is thinner, with higher insulation performance and thermal resistance. With several layers sprayed on the external roof, it integrates the external roof waterproofing system with thermal insulation system. Currently, it is optimal material for external roof waterproofing and thermal insulation.
High efficiency
Each machine could apply 500-1000 m2 per day(film thickness at 25-30mm)
Range of application
1. Outer wall & roof insulation, waterproof
2. Industrial light color steel tile inwall & outer wall insulation, waterproof
3.Grain storage & refrigeration storage insulation, waterproof
