Wall Spray Foam Insulation In Cambridge, Ontario

Old Walls Are Often Empty

A lot of century homes in Hespeler, Preston and Galt have stud walls with little or nothing inside. Once the plaster comes down for a renovation, the timing is perfect for wall spray foam insulation.

Foam fills the whole bay, seals around wiring and electrical boxes, and grips the back of the sheathing. Batts leave gaps at every one of those spots.

More Insulation In A Thin Wall

Older two-by-four walls are shallow. Closed cell wall spray foam insulation gives roughly double the R-value per inch of fibreglass, so a much warmer wall fits the same depth.

Open cell foam is cheaper and works well in interior partitions and where sound control is the goal.

Brick And Stone Houses Need Care

Solid brick and stone walls need a careful plan, because the masonry must be able to dry. We look at the wall, lay out the options and say so if foam is the wrong choice.

New Builds And Additions

On new homes and additions, foam helps the house pass its blower door test. Spraying fits around your builder's timeline so the walls are ready for the insulation inspection.

Wall Spray Foam Insulation And Sound

Open cell foam is softer and lighter, and it fills a wall cavity completely. That makes it useful for quieting a home office, a bedroom next to a busy hallway, or the wall beside a laundry room. Wall spray foam is not full soundproofing, but it does cut a good share of the noise that passes through an empty stud bay.

Preparing For Spray Day

Electrical and plumbing rough-ins should be finished and inspected before foam goes in, since it is hard to move wires afterward. Windows are masked and floors are covered. Foam that swells past the studs is trimmed flush so the drywall sits flat.

Closed Cell Or Open Cell For Your Walls

Closed cell wall spray foam suits outside walls, especially thin ones and any wall below grade, because it adds the most R-value per inch and blocks vapour. Open cell suits interior walls and deeper two-by-six outside walls where cost matters more than depth. A mix is common, such as closed cell on the outside walls of a century home and open cell between the bedrooms. Your estimate names the product for each wall.
