    Not much information on the Green Building Store for this material.

    What thickness is equal to 100mm king span?


    What thickness of warmcell 100 is equal to 100mm kingspan?

    1. Depends which grade of Kingspan.

    2. Need to look at thermal resistance. As a very rough guide, 35-45mm of extruded polystyrene came out roughly equal to 100mm of Thermafleece at South Yorkshire Energy Centre. Second Nature, the producers of Thermafleece, have a tech. consultant who will work out u values for you, and the tech. depts of most insulation manufs, such as K'span, will do likewise, so you can have the job done for you for free!

    According to the BBA certificates Therma Fleece has a thermal conductivity of 0.39 and Kingspan Thermapitch urethane foam has a thermal conductivity of 0.23. You'd need 170mm of Therma Fleece to equal 100mm of that Kingspan product.

    I've just heard a well-known DIY store has started stocking Thermafleece, hemp insulation and an ins product made of recyc. plastic bottles. Since I sell Thermafleece I'm off there tomorrow a.m. to see if they sell it cheaper than me! Bet (hope, in some ways - not in any way which will make me rich!) they do.
