Serious Insulation and Draft Reduction

At 1/8” or 3.2 mm thick, ECF is roughly twice as thick as the competition. This density equates to an R value of 0.48, which means that ECF provides serious insulation, not to mention its capacity to reduce drafts. More padding also means more cushion beneath your feet. That’s a benefit that tired toes and joints will undoubtedly appreciate. ECF easily smooths out subfloor imperfections and promotes even weight distribution to prevent floor damage. Smoother subfloors make for stronger joints, more stable floors and, ultimately, longer floor life.
