High energy bills are frustrating

Cold air sneaks through your siding, making your furnace work harder. This heat loss shows up on your utility bill every month. Airtight insulation seals those gaps so your home stays comfortable without the extra cost.

This upgrade also protects against the wet weather here. It prevents moisture from seeping behind the siding, stopping rot and mold on your home’s exterior. It’s a smart defense against the damp conditions common in this area.

Benefits of Exterior Insulation

Cold walls should not be normal. When exterior insulation fails, you feel every gust of wind. Adding a layer of insulation outside your home’s framing stops heat from escaping.

Our team installs rigid foam or mineral wool boards directly on your exterior sheathing. We then cover them with a weather-resistant barrier and new siding. This process wraps your home in a thermal blanket, stopping drafts and thermal bridges. That’s why many homeowners choose exterior insulation in Vancouver.

Why It Matters in Langley

Langley’s mix of older bungalows and newer homes all face wet, chilly winters. Without proper insulation, rain and cold can seep into walls, causing rot and high heating bills.

The Fraser Valley’s damp climate needs exterior insulation that can handle moisture. Many homes in Langley built before modern energy codes have little to no insulation in their walls. Upgrading the exterior stops drafts and protects your siding from moisture. For Langley homeowners, this means a warmer, drier home all year.

Exterior Insulation Process

In Langley, we start exterior insulation by taking off old siding to reveal the sheathing. Our team then attaches rigid foam or mineral wool boards directly to the framing. We use long screws and washers that go deep into the studs to withstand strong winter winds. We tape the seams between the boards to form a continuous air barrier.

Next, we add a water-resistive barrier and vertical furring strips over the insulation. This rainscreen gap lets any moisture that gets behind the siding drain and evaporate, which is important for Langley’s wet climate. Finally, we install siding made of fibre cement, vinyl, or wood to protect the insulation from rain.

Engineering Wall Assemblies

In Langley, our wall assemblies are designed to handle moisture from both outside and inside. By placing rigid insulation on the outside, we keep the dew point outside the sheathing. This helps keep the wood framing warm and dry, preventing condensation that can damage walls in older homes.

The rainscreen gap behind the siding serves as a drainage plane, allowing wind-driven rain to escape. When combined with taped insulation seams, this forms a continuous air barrier that stops drafts and reduces heat loss. Our fastening patterns are designed to withstand local wind loads while maintaining the insulation’s thermal performance.

Langley Permit and Bylaw Overview

For a single-family home in the City of Langley, structural exterior insulation work requires a building permit. However, non-structural exterior finish repair or replacement does not need a permit. If the exterior insulation changes wall assemblies, affects the structure, or is part of an addition, it is treated as an alteration/addition. This work must follow the permit application process, include drawings, pass inspections, and meet BC Building Code energy requirements. Purely cosmetic cladding or finish replacement can proceed without a permit.

In the City of Langley, exterior insulation work is considered construction activity. It must follow restricted construction noise hours. This work is generally allowed between 7:00 a.m. and 7:00 p.m. on weekdays and between 7:00 a.m. and 5:00 p.m. on Saturdays. Construction noise is not allowed on Sundays and statutory holidays unless a written exemption is issued by the Director of Engineering. Scheduling noisy exterior insulation operations outside these hours can lead to enforcement or require an exemption permit.

In the Township of Langley, exterior insulation work on a home is also treated as construction and must follow construction sound limits. Construction noise is generally permitted between 7:00 a.m. and 8:00 p.m. on weekdays and Saturdays. Noise is not allowed on Sundays or statutory holidays unless a construction sound exemption is approved. Exterior insulation contractors must plan noisy activities, like fastening exterior panels and using powered equipment, within these hours or obtain a Township sound exemption in advance.
