Preparation

Subfloor preparation

Thoroughly clean the concrete or the wooden surface: remove all grease, grit and wood particles. Correct any imperfection of the subfloor in accordance with general surface preparation procedures.

Before membrane installation

Aluminized side must be installed face up to reflect temperature back into the room.

Can be cut with a retractable blade or scissors (figure 2).

Make sure the membrane is installed at right angle with the floor covering.

Allow an extra percentage to prevent losses caused by the cutting of the membrane, angles and closets.

Prevent transfer of sound by vibrations :

• To assure maximum soundproofing performance, it is very important to : Leave a space between the wall and the floor covering (expansion space) to prevent the transfer of vibrations (figure 1).
• Do not install moldings directly on the floor covering, leave the space of a cardboard to prevent the transfer of vibrations.

Choice of adhesive

We suggest the use of the rubber based adhesive AD-316 to obtain maximum soundproofing results. The adhesive is solvent-free, VOC compliant and odorless. It can also be used to glue down engineered floors.

If you choose to glue down the membrane with an appropriate waterbased adhesive, you must wait at least 24 to 48 hours before installing the floor covering. This delay is necessary for water evaporation. A premature installation can cause the floor covering to warp. You must evaluate conditions prior to installation. Urethane adhesive can also be used.
