Installation Instructions for Redupax Underlayment

Floated Engineered Hardwood Flooring

Redupax underlayment can be installed over concrete, lightweight gypsum topping or wood frame construction.  Redupax is shipped in workable packages of 87 sf per pack and weighs approximately 50 lbs.  In most instances a 4 mil vapor barrier is required for moisture control and a 3/8" gap is required for both wood expansion and acoustics to avoid a flanking path for sound.
