Shipping Container Insulation

Professional Container Insulation in the GTA

Konstruction Group provides professional shipping container insulation services in Toronto and the GTA. Shipping containers and sea cans are increasingly popular for storage buildings, workshops, pop-up retail, and modular construction projects. However, their steel construction creates significant condensation and temperature control challenges. We install closed cell spray foam insulation to transform containers into comfortable, moisture-free spaces suitable for year-round use.

Why Shipping Containers Need Insulation

Steel shipping containers are excellent at one thing: transporting goods across oceans. They're not designed for human occupancy or temperature-sensitive storage. Without insulation, containers experience extreme temperature swings - scorching hot in summer, freezing in winter. Worse, the temperature differential between inside and outside causes condensation (container rain) that damages contents and promotes mold growth. Proper spray foam insulation solves both problems.

Container Insulation Applications

• Storage Containers – Protect equipment, furniture, and temperature-sensitive items from condensation and temperature extremes
• Workshops & Studios – Create comfortable year-round workspaces for trades, artists, and hobbyists
• Pop-Up Retail & Restaurants – Insulated containers for food service, retail kiosks, and temporary commercial spaces
• Modular Buildings – Multi-container structures for offices, housing, and commercial applications
• Cold Storage – Enhanced insulation for refrigerated or temperature-controlled storage
• Hunting Camps & Cottages – Remote structures where containers provide a durable, secure shell

Closed Cell Spray Foam for Containers

Closed cell spray foam is the ideal insulation for shipping containers. It bonds directly to the corrugated steel walls, creating a seamless thermal and moisture barrier. Unlike batt insulation that requires framing and leaves air gaps, spray foam fills every corrugation and seals the entire interior surface. The closed cell structure prevents moisture penetration and condensation - the primary problem with uninsulated containers.

Container Insulation Options

• 1" Closed Cell (R-7) – Minimum for condensation control in storage applications
• 2" Closed Cell (R-14) – Standard for workshops and seasonal use spaces
• 3" Closed Cell (R-21) – Enhanced thermal protection for year-round occupied spaces
• Walls, Ceiling & Doors – Complete coverage including container doors for maximum efficiency

Container Preparation

Before spraying, containers need proper preparation. We inspect for rust and holes, address any structural concerns, and ensure surfaces are clean and dry. Existing rust should be treated before insulation. If you're planning electrical, HVAC, or plumbing, rough-in should be complete before we spray. We can coordinate with your other trades for proper sequencing.
