Steel Pole Barns Drip When Warm Air Meets Cold Metal
Closed cell spray foam insulation ends roof drip by keeping damp air away from the steel. In a bare pole barn, breath from cattle, steam off wet hay or a salamander heater rises to the roof sheets on a frosty night. The sheets are colder than the dew point, so the moisture turns to droplets and rains back down.
Those droplets rust the purlins, spot the paint on a new combine and wet the bedding pack. Spray foam insulation packed tight to every rib and screw head holds the roof sheets above that dew point, so the droplets never form. Our pole barn spray foam insulation page shows the detail at posts, girts and sliding doors.
Livestock Barns Need Insulation That Shrugs Off Moisture
Closed cell foam is our pick for a barn full of animals because water beads on it instead of soaking in. Woolwich has more farms than any other municipality in Waterloo Region, and most of them house cattle, laying hens, broilers or hogs. A full barn breathes out a surprising amount of water every hour.
Fiberglass in that air gets heavy, sags off the ceiling and turns into a mouse hotel. Cured foam stays put, takes a pressure washer and leaves vermin no fluff to burrow into. The livestock barn spray foam insulation page covers dairy, beef, poultry and hog buildings.
Drive Sheds Often Turn Into Heated Workshops
Spray foam insulation is how a drafty drive shed becomes a shop you can stand in during January. A lot of Woolwich farms have a steel building that held a combine for twenty years and now holds a welder, a lathe and a woodstove.
Heating a building and working in it can change the rules for bare foam. Foam inside a heated workspace usually needs a cover, such as drywall or a fire-rated paint, and the township building department makes that decision for each building. We bring it up during the first walk-through so the cover is in the budget from the start. The workshop spray foam insulation page goes further into shop and drive shed jobs.
Old Bank Barns Have Damp Stone Lower Levels
When a bank barn's stable level is being turned into heated space, closed cell spray foam insulation is the usual answer. Many old barns near Elmira and St. Jacobs were built into a hillside, with stone walls below and a ramp up to the threshing floor.
The uphill stone wall touches wet earth twelve months a year. Batts pressed against that stone can turn black with mould by spring. Foam bonds to the stone, holds back the damp and insulates in a single coat. We check the mortar and the drainage first, because foam cannot stop running water.
Farmhouse Attics Lose Heat Through Gaps In The Ceiling
Attic spray foam insulation closes the holes in the ceiling before it adds R-value. In a century farmhouse, heat slips out around light boxes, the plumbing vent, the chimney and the top plates of every interior wall.
Waterloo Region gets about 160 cm of snow in a typical winter. Warm attic air melts that snow from underneath, the melt freezes at the eaves, and an ice dam pushes water under the shingles. Sealing the ceiling or foaming the roof deck keeps the attic cold and the roof dry. The attic spray foam insulation page compares both ways.
Village Basements Under Older Homes Feel Cold And Damp
Basement spray foam insulation turns bare block or stone into a warm, dry wall. Older homes in Elmira and St. Jacobs often have foundations with nothing on them but whitewash, and the basement stays chilly with the furnace running full tilt.
Closed cell foam grips the masonry, so humid summer air never finds a cold surface to sweat on. It is the step most people take before framing a rec room. The basement spray foam insulation page shows how the rim joist gets done on the same day.
Crawl Spaces Under Additions Freeze Pipes
Crawl space spray foam insulation keeps the kitchen floor warm and the water lines thawed. Farmhouses here were often added onto two or three times, and the back kitchen or mudroom usually sits over a short crawl space with open vents.
We close the vents, spray the block walls and the rim, and lay down a ground sheet. The space then stays close to house temperature all winter. See the crawl space spray foam insulation page for tight-access jobs.
Attached Garages Pull Cold Into The House
Garage spray foam insulation fixes the cold bedroom above the garage and the chilly kitchen wall next to it. Those are often the two coldest surfaces in a house, since the garage next to them can sit below freezing for weeks.
Foam also makes the garage itself a usable place to fix a lawn tractor or lift weights. The garage spray foam insulation page covers attached and detached buildings.
New Breslau Homes Can Be Built Tighter From The Start
New home spray foam insulation costs the least labour while the studs are still bare. Breslau has grown faster than any other community in the township, and custom homes keep rising on rural lots near Conestogo and Maryhill.
Foam in the walls, rim boards and roof of a new build cuts air leakage at its source and helps the blower door number. Read about it on the new home spray foam insulation page.
Closed Cell Fits Most Farm And Foundation Work
Of everything on our rig, closed cell spray foam insulation gets used the most out here. Expect around R-6 to R-7 for each inch, a vapour stop at full thickness, and extra stiffness in whatever it coats.
Open cell foam is lighter, softer and cheaper. It belongs in heated house walls and some attics, and never in a barn or against a foundation, because vapour moves straight through it. Our closed cell spray foam page sets the two side by side.
What Spray Foam Insulation Costs Around Elmira
Ontario prices for spray foam insulation on a pole barn, drive shed or shop generally land between $2 and $5 a square foot of foamed surface. Basement walls run $3 to $5.50, garage walls and ceilings $3 to $6, and closed cell on an attic roof deck or crawl space walls $3.50 to $7.
Those numbers are market ranges, and your building sets the real one. Thickness, ladder or lift access and the shape of the roof matter most. The written figure from your free visit is the price, and our smallest job is $1,500.
Store Kits Fall Short On Big Buildings
Two-tank foam kits from the farm supply store are fine for a few gaps around a pipe. They are the wrong tool for a barn ceiling or a basement. The tanks cool as you spray, the mix drifts, and off-ratio foam can shrink away from the framing or smell for months.
Our rig heats both parts and holds the ratio and pressure steady for hours. We read the surface temperature first and build the foam in layers, so it cures hard and stays bonded.
