DuPont™ Climate Systems are membrane insulation solutions that combine the latest generation of low emissivity diffusion open membranes such as Tyvek® Enercor® on the cold side of traditional insulation with a reflective VCL, DuPont™ AirGuard® on the warm side. The systems are complemented with a range of accessories such as tapes to optimize the efficiency. The result is an all-in-one building envelope membrane solution that covers an entire house, boosting existing insulation, making the building airtight, whilst enabling it to fully 'breathe'. The robustness of the solution and construction details ensure that insulation remains dry and is not exposed to air infiltration, which would dramatically reduce its performance.
