Does Liquid Vinyl Siding help insulate?
Yes, but only to the extent of sealing the structure and reducing conduction and convection heat loss in winter and gain in summer. Measuring a true R-Value in a coating is difficult. Beware of insulation claims being made by other companies with spray on products. They are unverifiable and the FTC is disciplining companies making fictitious insulation claims. A spray on coating or a ceramic paint cannot provide insulation equal to that inside the walls, nor will it significantly reduce your energy bills. The true value of Liquid Vinyl Siding is in the elimination of future maintenance, continuing beautiful appearance and what it can add to the property’s resale value.
