Gypsum Underlayment
Gypsum underlayment is a lightweight, self-leveling material installed over wood or concrete subfloors to create a strong, even surface for finished flooring. It offers superior sound control, fire resistance, and versatility in multi-story construction — making it an essential component in apartment buildings, condominiums, hotels, and commercial spaces.
