Living small doesn’t mean sacrificing comfort — a well-insulated, energy-efficient tiny home can feel warmer and cozier than a traditional house in the depths of winter. The difference is made before you ever move in: in the walls, roof and floor.
To stay warm below freezing, you need high R-value insulation in the walls, roof and floor — not just the walls. Floors matter enormously in small structures; cold under your feet reads as a cold house no matter the thermostat.
Closed-cell spray foam delivers excellent air sealing and thermal resistance — perfect for tight spaces — and it doubles as a vapour barrier while stiffening the assembly. Paired with steel framing, it produces a shell that doesn’t shift, gap or settle over years of freeze-thaw.
Quality windows, sealed penetrations, insulated skirting on chassis-built units, and right-sized electric heat. Our homes ship winter-ready at roughly R-20 with baseboard heat standard and heat-pump options — built for the worst week of a Canadian February, not the average one.
