Heating costs too high

When your siding stays cold, your heating system works harder, driving up your bills. Continuous insulation in this area creates a thermal barrier that keeps heat inside.

This upgrade also manages moisture and reduces outside noise—a benefit in busier neighborhoods. With our damp climate, a well-insulated exterior prevents wear that leads to costly repairs.

Reduce Heat Loss Effectively

Cold siding means your walls are losing heat. This makes your furnace work harder to keep your home warm. Continuous exterior insulation in Vancouver wraps the outside of your house in a thermal blanket. This stops heat from escaping through the studs and keeps warmth inside.

We remove the old cladding and attach rigid foam or mineral wool panels directly to the sheathing. Then we seal every seam. New siding and trim go back on top. Your walls dry out while the R-value increases—no need for interior work, no lost floor space, just a quiet, warm home that costs less to heat.

Designed for Port Moody's Climate

Port Moody is at the head of Burrard Inlet, where damp air meets cold winds from the valleys. This moisture affects your siding and pulls heat from uninsulated walls. Homes here need insulation that can handle wet and dry cycles without causing rot.

Older Port Moody homes—like split-levels from the seventies and hillside ranchers—often sit on shaded lots with little sun. Adding exterior insulation keeps the sheathing above the dew point during wet winters. This reduces condensation risk and makes those north-facing walls feel warm for the first time.

Installation Techniques

In Port Moody, we start exterior insulation installation by removing old siding and checking the sheathing for rot. We attach rigid panels, usually XPS or dense mineral wool, directly to the sheathing and into the studs using long screws with wide plastic washers. This creates a continuous thermal layer around the whole home, which helps eliminate cold spots at each framing member.

Moisture management is very important in this area. Mineral wool lets vapor escape, while XPS resists water absorption in damp conditions. We tape seams for an air seal and install a rainscreen gap over the panels before adding new siding. Any rain that gets behind the cladding drains out the bottom, keeping the sheathing dry.

Dew Point Management

Heat escapes through solid wood studs faster than through insulated areas. By wrapping the sheathing in continuous exterior insulation, we move the dew point outward. In Port Moody’s wet winters, this keeps the wooden sheathing warm enough to stay above the condensation point, which prevents moisture from forming inside the wall cavity.

The assembly works as a layered control system. A drainage plane behind the siding channels water out, while flashing tape at openings directs moisture down and away. Vapor-open insulation allows humidity to escape through the rainscreen gap, and taped seams stop air leaks from winds. This four-layer envelope effectively manages moisture from the coastal environment.

Permits for Exterior Insulation

A building permit from the City of Port Moody is needed before starting any exterior insulation work that involves building envelope changes. This includes inspections of insulation, vapour barriers, framing, and windows before they are covered. The insulation details must meet the BC Building Code, zoning, and other City rules.

The City’s residential building permit guide states that cross-section drawings listing wall assembly details, including insulation R-values, are required for any exterior insulation projects that go beyond basic finish replacement. This includes adding new continuous exterior insulation or changing wall assemblies.

The City’s Sound Level Bylaw controls construction noise. It limits exterior insulation work to specific hours on weekdays, with stricter hours on weekends and holidays. Contractors must plan noisy activities within these hours or get special permission for any work outside those times.
