How do SIPs manage moisture better than conventional framing?

A conventional stick-framed wall is built from dozens of individual components, with multiple layers, joints, and transitions that must be properly installed and sealed on site.

Structural Insulated Panels (SIPs) simplify that process by combining structure and insulation into a single factory-built panel. With fewer field-assembled layers and transitions, there are fewer opportunities for gaps that can allow unwanted air and moisture movement.

Proper sealing, flashing, and detailing still matter, but reducing the number of on-site connections to manage can make a real difference in maintaining a continuous building envelope.

For builders and designers across Western Canada, understanding how different building envelope systems manage moisture is especially important given the region's varied climates.

3 stories. 25 units. This multi-family residential building in Banff, Alberta, was constructed using Structural Insulated Panels, SIPs, which combine an insulating foam core with two structural facings in a single panel.

That construction gives a building high R-value insulation and an airtight envelope, two things that matter when you’re heating through sub-zero mountain winters.

West-Eco SIPs supplied the panels for this project. If you have an upcoming multi-family or commercial project, let’s talk about how SIPs can deliver that kind of performance from day one: https://hubs.ly/Q04B8WV20

Step 3 of the BC Energy Step Code has been the provincial minimum for new Part 9 buildings since 2023, and some local governments already ask for more. The Province’s stated goal is for all new buildings to be net-zero energy ready by 2032, which is Step 5. The question for builders and designers is whether the envelope they choose now has room to grow into that.

SIPs give you a head start. A continuous insulated core, panels sealed at the joints, and fewer thermal bridges make the envelope side of the Step Code- thermal performance and airtightness- easier to hit with a thinner wall.

West-Eco SIPs supplies SIP building envelopes across BC, Alberta, and the Northwest Territories. Pricing a project now? Let’s talk about which step you’re designing for and what it takes to get there: https://hubs.ly/Q04zYz7r0

It’s early in the season, but cold weather is when airtightness shows up fastest, in drafts, cold floors, and heating bills that creep up.

In a SIP wall, the insulated core is continuous, and the panels are sealed at the joints. Airtightness is built into the assembly, not left to how well every gap and pe*******on gets sealed afterward.

It’s also one of the metrics the BC Energy Step Code measures, which is why it pays to design it in from the start instead of chasing it at the end.

Airtightness isn’t just a number from a blower door test. It’s a design strategy. Here’s how we think about it: https://hubs.ly/Q04zN_FD0

Review the floor plan for your next clinic, school, restaurant, or multifamily amenity space and count the columns that get in the way of the layout.

A SIP roof panel can typically span up to 20 feet, reducing the need for interior columns. On commercial projects, that shows up in practical ways:

→ Flexible layouts, so the space can be reworked for the next tenant or use without planning around posts
→ Open sight lines through lobbies, dining rooms, classrooms, and gathering spaces
→ Fewer interior supports to coordinate with mechanical, electrical, and furnishings
→ A roof that is structure and insulation in one panel, so the span is also part of the thermal envelope

Span depends on panel thickness, snow and wind loads, and connection details, so we start from the engineered load charts on every project. Roof loads vary a lot across BC, Alberta, and the Northwest Territories, and that is where the real number comes from.

Spray foam vs. SIPs comes up a lot, and the comparison usually skips a step.

Spray foam is an insulation material. It goes into a wall that's already framed, which means the studs are still there, and studs are where heat finds its way out.

A SIP is the wall itself. Structure, insulation, and air sealing arrive together as one panel, with a continuous rigid EPS or GPS core installed at the factory instead of applied on site. The airtightness comes from the panels and their sealed joints, not from a separate step later.

That continuous layer, plus an R-value (RSI value) that holds steady over time, is a big part of why SIPs help projects reach higher steps of the BC Energy Step Code with thinner walls.

Different tools for different jobs. If you're weighing wall systems for a build in BC, Alberta, or the Northwest Territories, we're happy to walk through how they compare on your actual assembly. Let's talk: https://hubs.ly/Q04zd6Bf0

Energy efficiency begins with the frame, not the finishes. Ask builders who've made the switch to Structural Insulated Panels (SIPs) why they did it, and the reasons tend to repeat.

→ Energy efficiency. A SIP wall and roof assembly is a solid, continuous core of EPS insulation between structural facings, with none of the gaps or compression points you get in a stud cavity. Less air leakage, more consistent R-value (RSI value) across the whole assembly, not just where the insulation happens to sit right.

→ Onsite speed. Panels arrive pre-cut, with window and door openings already routed at the factory. Crews are assembling, not measuring and cutting, which cuts the labour hours and the number of trade-days needed to close in a building.

→ Strength that holds up over time. A SIP's structural skins are laminated to the core as one rigid unit, so the wall isn't relying on individual studs that can twist, shrink, or warp the way dimensional lumber can over the life of a building.

These are the practical reasons builders across BC, Alberta, and the Northwest Territories keep choosing panels over stick framing. Want to see the math on your next project? Let's talk.

Wildfire risk has become a real design consideration across BC and Alberta, and the building envelope is part of that conversation.

Embers and radiant heat are two of the primary ways structures can ignite during a wildfire. Structural Insulated Panels (SIPs) create a continuous, tightly sealed building envelope that can help reduce potential pathways for ember intrusion while providing tested fire performance as part of properly designed wall assemblies.

No building system is fireproof. But thoughtful material and envelope choices can help reduce risk.

We take a closer look at SIPs, wildfire-resistant construction, and what builders and designers should consider. Read the full breakdown: https://hubs.ly/Q04yJlJG0

Noise from the next-door unit is one of the most common complaints in multifamily buildings, and it’s much harder to address once the walls are closed in.

SIP party wall assemblies have tested at STC 58 to 59, helping reduce sound transmission between spaces. The solid foam core and structural facings create a more continuous assembly than conventional stud walls, adding acoustic performance along with the energy and building envelope benefits SIPs are known for.

Sound control can be especially important in:

✓ Apartments and condos
✓ Hotels
✓ Student housing
✓ Senior living
✓ Schools and offices

No wall assembly eliminates sound completely, but designing for acoustic performance from the beginning can make a noticeable difference for the people who eventually live, work, or stay there.

Most building decisions can be revisited. The envelope isn't one of them.

That's exactly why the envelope is where a building should start, not an afterthought once the floor plan and finishes are locked in. Structural Insulated Panels (SIPs) build the structure and the insulation as one continuous system from the outset, engineered to eliminate the gaps, thermal bridges, and inconsistencies that show up in traditionally framed walls later.

The result shows up across the whole project:
→ Tighter air control at every connection
→ Reduced thermal bridging
→ Predictable, testable performance before drywall goes up
→ Less heat loss across the wall and roof assembly
→ A more direct path to BC Energy Step Code compliance

For builders and designers across BC, Alberta, and the Northwest Territories, that's no longer just best practice. It's the direction the code is heading.

A building only gets one chance at its envelope. SIPs make sure that first chance is the right one. → https://hubs.ly/Q04y2MK70
