Selecting the correct r values for spray foam insulation is a nuanced process that depends on your specific application, whether it be a crawlspace, exterior wall, or attic. In the Langley area, the high water table and humid air make the moisture-resistant properties of closed-cell foam particularly valuable. With R-values ranging from R-6 to R-7 per inch, it provides a powerful barrier against the damp BC winters. Our team at Western Insulation guides you through the selection process, helping you decide between open-cell and closed-cell options based on your thermal and acoustic needs. By targeting the right R-value for each zone of your home, you ensure maximum comfort and compliance with the BC Energy Step Code. Let our professionals help you build a more sustainable and comfortable home with the highest-rated insulation on the market
