Closed cell spray foam cures hard and dense, so one coat of it insulates, air seals and blocks water vapour together. We spray more of it on farm buildings, foundations and steel roofs than anything else.
Every project is insured, and each closed cell spray foam quote shows which surfaces get foam and how deep it goes.
Closed cell spray foam delivers R-6 to R-7 in a single inch of depth. Open cell, by contrast, lands around R-3.5 to R-3.8 for the same inch. Closed cell is rigid and its cells are sealed, so water vapour does not pass through it once it is thick enough.
Open cell is soft and spongy. It seals air well, but it lets vapour through. That makes it a fit for inside walls and some attics, but not for barns or basements.
Closed cell keeps water from forming on cold surfaces. On a steel roof, a concrete wall or a stone foundation, the foam keeps the inside face warm. With no cold surface, damp air has nowhere to drop its water.
That is why closed cell is the right foam for Woolwich pole barns, livestock barns, basements and crawl spaces.
Closed cell bonds to the surface and cures hard. That adds stiffness to walls and roof decks. On older post frame buildings, it can help hold steel sheets tight to the framing.
Open cell foam costs less per inch and works well in walls inside a heated house. It also deadens sound between rooms. We use it where vapour is not a concern. For the attic choice, see our attic foam page.
Closed cell spray foam is the standard product for steel farm and shop buildings because it sticks to bare metal. Batts need a frame to hang in and a vapour barrier to protect them, and neither lasts long in a barn. Foam goes right onto the ribs of the sheet, so no gap is left for moisture to collect behind it.
On a cold storage building near Linwood or Hawkesville, two inches is often enough to stop drip. A heated barn or shop commonly gets three to four inches. We gauge the depth across the roof and walls as we go, and the readings go on your paperwork.
Closed cell also works below grade, on foundation walls and in crawl spaces. Ground moisture moves into concrete all year, and a foam that blocks vapour keeps it out of the house and away from the framing.
On attic roof decks and crawl space walls, closed cell typically costs $3.50 to $7 a square foot in Ontario, and less on barns and shops. Phone (226) 407-7743 and we will look at the building and send the figure in writing. Our spray foam insulation home page has the full list.
One trip down the lane often covers the farmhouse, the shop and the hog barn.
Pole barn spray foam insulation bonds to the roof steel and wall sheets of a post frame building, so frost and sweat have no cold face to form on. A single closed cell layer wraps the ribs and the girts.

Livestock barn spray foam insulation keeps the moisture from animals' breath off the roof and walls, so steel stays dry and rafters stay sound. Closed cell foam takes a pressure washer and gives pests no fluff to nest in.

Workshop spray foam lets you heat a steel shop or old drive shed and actually keep the heat. Foam across the walls and roof stops drafts and keeps warm air from escaping through bare sheeting.

Attic spray foam insulation plugs the leaks in a ceiling and adds R-value on the same trip. It suits century farmhouses, village homes and newer houses with awkward roof lines.

Basement spray foam turns a cold foundation into a warm, dry wall that is ready for studs. Closed cell foam grips block, stone and poured concrete alike.

Crawl space spray foam insulation coats the block walls and rim of a short crawl space, keeping the kitchen floor warm and the water lines thawed. Closed cell foam holds back ground moisture as well as cold air.

Garage spray foam stops the chill that seeps from a garage into the bedroom above it and the kitchen beside it. It also turns the garage into a warmer spot to work, park and store things.

New home spray foam fills the walls, rim boards and roof of a house while the studs are still bare. That stage is the easiest time to build a tight, quiet, efficient home.

A few details about the building are enough, and a call follows to fit a visit around milking or chores. Calls go to +1 (226) 407-7743.
