Grain Bin & Silo Insulation in Ontario
Thermal protection for stored grain: closed-cell foam controls the condensation and temperature swings that spoil the crop you already paid to grow.
Grain going out of condition in storage is money evaporating. Steel bins track outside temperatures, and every big swing drives moisture migration inside the grain mass — warm grain against cold steel means condensation, crusting, and spoilage at the walls and under the roof.
Closed-cell spray foam on bin walls and roofs breaks that cycle. The steel stops swinging with the weather, the grain mass stays thermally stable, and condensation at the shell stops. Aeration systems work with a stable mass instead of chasing hot spots.
Grain bin and silo insulation is available across SW Ontario — and we mobilize provincially for commercial elevators and large storage sites.
We mobilize anywhere in Ontario for projects at scale.
The Problem
Steel Bins Move Moisture
In late fall, warm grain sits against steel that's cooling fast. Moisture migrates to the cold surfaces — bin walls and the underside of the roof — where it condenses, wets the grain, and starts spoilage. Spring reverses the gradient and does it again.
Aeration manages the symptom but fights the building the whole time. Insulating the shell attacks the cause: no cold steel, no condensation surface, far smaller temperature gradients inside the mass.
Why It Works
What Insulated Storage Buys You
- Stops condensation on bin walls and roof underside
- Stabilizes grain mass temperature through weather swings
- Reduces spoilage, crusting, and out-of-condition grain at the shell
- Aeration runs less and works better against a stable mass
- Exterior application — no contact with stored grain
- Protects the bin structure itself from condensation corrosion
Where We Apply It
Storage We Insulate

FAQ
Common Questions
Outside. Exterior application means no contact with grain, no interference with aeration floors or unload equipment, and the steel itself is kept warm — which is what stops interior condensation. A protective UV coating finishes the exterior.
