Conditioning a crawlspace involves polyethylene sheathing used in conjunction with a ccSPF insulated perimeter to safeguard mechanicals, foundation, and indoor air quality. Sealed off from both outside air and soil vapors, the house's own HVAC system can easily regulate air flow within the space, creating an even and homogenous environment nearly identical to the living areas.
Excellent cost-to-performance insulator mostly used for thermal and air barrier assemblies and where high volume is required; ocSPF is the most popular variant of foam insulation for residential construction due to its nominal water permeability which allows leaks in wood-frame structures to be properly identified before rot can set in.
A lightweight, super-durable sprayed-in-place roofing system that enhances building energy efficiency; SPF roofing can be formed to any roof and any roofing substrate to completely fill gaps and seams, contour parapets and slopes and generally weather-proof to a degree unrivaled by competing roof systems. SPF roofing is completely sustainable, easily repairable and can effectively last indefinitely.
