Firm-Fill 3310, a new gypsum concrete underlayment, and Hacker Sound Mat II, an environmentally friendly and costefficient new sound mat, are now included in 82 UL listings and available nationwide from Hacker Industries, Inc. The UL listings detail floor assemblies utilizing a Hacker Floor underlayment as an integral component to achieve one-, two-, three- and four-hour fire ratings.
Firm-Fill 3310 can be poured before or after drywall and delivers compressive strengths up to 3300 psi. The product’s low water demand rapidly eliminates water, allowing for accelerated drying time and superior surface hardness.
