Installing Soundproof Insulation in Ceiling

DSC 5292 Installing Soundproof Insulation in Ceiling

Over the weekend we installed soundproofing insulation between the beams in the ceiling. Insulation in the ceiling isn’t necessary but it does make a room a lot quieter. We used Roxul Safe’n’Sound insulation under recommendation of our local lumber yard, Gilbert & Cole.

The product is really cool because it’s fire-resistant and made from a material called, stone wool. Stone wool is a by-product of volcanic activity and was found in Hawaii at the beginning of the century. According to Roxul’s website, in its manufactured state, stone wool combines the power of rock with the characteristics of typical insulation wool. Stone wool is water repellent yet vapor permeable. The insulation cannot absorb water so the R-value is not affected. It is completely resistant to rot, mildew, mold and bacterial growth.

The insulation is easy to install. Cut strips using a simple saw and stick it up into the ceiling cavity between the beams—we used the old lathe we removed from the ceiling to secure the panels. Some of the panels fit in perfectly with no cutting but in the smaller room we had to trim each piece because the width between the beams is narrower. Blueboard will be screwed into the beams later this week when the plasterer comes. Above and below photos of Greg installing the insulation in our den.

Update: The insulation is great and makes the house so much quieter. See photos of the blueboard being installed as well as the base coat plaster ceiling going up here.

    I’ve been following you for quite a while and it’s always exciting to see a new post. The stone wool is fascinating. I’ve never heard of it. I’m loving what you’re doing with this old house.
