Insulayment®
Multi-Purpose Acoustical Underlayment
Product Information
Made from recycled materials in a patented process where air-laid filaments create a capillary effect to absorb impact and airborne sound, Insulayment is the best acoustic underlay for wood flooring. This acoustical underlayment insulates the transfer of impact noise to lower level rooms and better supports wood flooring than commonly prescribed 15 lb asphalt saturated felt paper. Insulayment's sound ratings meet or exceed most building code requirements for multi-family dwellings.
Available in 3' x 33.4' (100 sq ft) or 6' x 60' (360 sq ft) Rolls
Features and Benefits
Sound Reduction - Absorbs sound, keeps it from traveling to other rooms. Also help to make the wood floor feel more solid underfoot.
Glue Down Wood Flooring - The recycled fiber composition provides excellent bonding strength with adhesives and thin set mortars.
Nail Down Wood Flooring - Not recommended where wood flooring is less than 3/8" thick or less than 3" wide.
Smoothing Out Imperfections - This cushion is firm and supportive but flexible enough to form around subfloor surface roughness, helping to cut down on extra surface prepping time.
Approved For In-Floor Heating Systems - Allows heat to permeate evenly while helping to protect the floor covering material from thermal shock.
Insulating Value - Provides additional comfort to the entire home during seasonal temperature changes.
Made From Recycled Material - A patented manufacturing process repurposes post-industrial and pre and post consumer materials into high-performance underlayment.
Certified Clean and Safe Indoor Air Quality - No VOC's (Volatile Organic Compounds) or off-gassing from materials.
Competitively Priced - An ideal upgrade from 2-in-1 polyethylene or polystyrene products and is less costly than most frothed foam, cork or rubber underlayment with similar sound numbers.
