When designing, building, or renovating a building, or finishing a basement or an attic, it is important to include sound and thermo insulation in your walls and ceilings. There are 3 ways to reduce or prevent the sound transmission through walls at the time of construction. Increase the mass with an extra layer of drywall, break the vibration link between rooms and improve the cavity absorption or all three.

Standard insulation products absorb some sound, and acoustic insulation absorbs more. However, insulation also reduces the reverberation which causes a sound to echo or bounce back into a room creating disturbing feedback. The insulation will reduce sound transmission through the wall and improve the sound within a room.

A typical interior 2×4 wall with 1/2” of drywall on both sides has a rating of STC 34. Adding standard fiberglass insulation improves the rating to STC 39. Adding sound rated insulation can improve that to STC 45. Building the same wall using 2-1/2” metal studs with 1/2” drywall on each side you get an STC of 34; add same sound rated insulation can bring the rating to STC 47. Using 5/8” drywall instead of 1/2” on the steel studs brings the sound insulated wall up to STC 49.

Every residential building needs thermal and sound proofing insulation. Let the Professionals renovate your property, so you can enjoy life in a quiet and eco-climate environment and save you money from energy consumption.
