Hit BC Step Code targets with less guesswork. Airtight Solutions delivers proven results for Sea to Sky projects.
Building in Whistler and Squamish presents unique challenges for meeting BC’s increasingly stringent Step Code requirements. From extreme temperature fluctuations to heavy snow loads and moisture management, Sea to Sky builders need envelope solutions that perform reliably in mountain conditions. Aeroseal
Envelope technology provides precise, measurable air sealing that consistently transforms marginal air changes per hour (ACH), which results in Step Code compliance—often improving from 3.5 ACH50 to under 1.0 in a single application.
Whistler & Squamish Building Challenges Solved by Aeroseal Envelope
The Sea to Sky corridor’s demanding climate conditions create significant envelope performance challenges that conventional sealing methods struggle to overcome. Mountain homes in Whistler and Squamish face fierce winter storms, dramatic freeze-thaw cycles, and extreme pressure differentials that can compromise even carefully detailed building envelopes.
These conditions make conventional caulking and taping methods particularly unreliable, as they often miss critical leakage points in complex roof assemblies and connections. Many Sea to Sky builders have experienced failed blower door tests despite careful manual sealing, leading to costly rework and construction delays.
Aeroseal Envelope technology addresses these challenges by pressurizing the entire building and actively seeking out all leakage pathways—even those hidden within assemblies that are inaccessible to conventional sealing. This approach is particularly valuable in mountain construction where roof complexity, high ceilings, and extensive glazing create numerous potential failure points.
Aeroseal Applications for Whistler & Squamish Construction Projects
The Sea to Sky region features diverse building types that all benefit from Aeroseal’s comprehensive approach to envelope sealing:
Alpine Chalets and Custom Homes: High-end properties in Whistler neighbourhoods like Kadenwood and Sunridge Plateau frequently feature complex roof designs and open floor plans that create air sealing challenges. Aeroseal technology has helped multiple luxury builders achieve Passive House and Net-Zero standards without compromising architectural vision.
Multi-Family Developments: Growing communities like Squamish’s Waterfront Landing and University Heights have used Aeroseal to ensure their multi-unit projects meet Step Code requirements efficiently across multiple units, streamlining the construction process.
Mountain Commercial Buildings: The technology has been successfully deployed in commercial applications throughout the corridor, including retail spaces in Whistler Village and Function Junction warehouses, helping these structures achieve higher energy performance while maintaining comfort in extreme conditions.
Meeting Whistler & Squamish's Step Code Requirements
Both Whistler and Squamish municipalities have aggressively adopted the BC Step Code, with Whistler requiring Step 3 compliance for most new construction and Squamish advancing toward Step 4 for many building types. These requirements translate to demanding airtightness targets that many conventional building techniques struggle to achieve.
Aeroseal Envelope technology integrates seamlessly with both communities’ local permitting and inspection processes. Our technicians coordinate directly with energy advisors throughout the Sea-to-Sky region to ensure testing procedures align with municipal requirements.
Our documented results provide the verification data required by both Whistler and Squamish building departments, eliminating uncertainty in the compliance process. Most importantly, Aeroseal delivers these results on the first test, avoiding the delays familiar with traditional sealing methods that may require multiple testing attempts.
Benefits for Whistler & Squamish Builders and Developers
Sea to Sky builders partnering with Airtight Solutions gain significant advantages:
Predictable Step Code Performance: Rather than guessing whether manual sealing will pass increasingly strict blower door tests, Aeroseal provides real-time measurement and guaranteed results, crucial for meeting Whistler’s strict 3.0 ACH50 requirements or Squamish’s advancing targets.
Mountain-Specific Solutions: Our experience with complex roof assemblies, timber frame construction, and extreme weather considerations means we understand the unique challenges of building in Whistler and Squamish.
Construction Schedule Reliability: By eliminating failed blower door tests and rework, projects stay on schedule even during tight construction windows dictated by mountain weather conditions.
Enhanced Energy Performance: Beyond code compliance, Aeroseal creates truly comfortable, efficient homes that perform well in extreme temperature conditions—reducing the significant heating loads common in Sea to Sky properties.

Whistler & Squamish Aeroseal Envelope FAQ
The Aeroseal process has been calibrated specifically for performance at elevations throughout the Sea-to-Sky corridor, from sea level in Squamish to alpine applications in Whistler.
The aerosol-based application is particularly effective for the complex roof assemblies and timber connections standard in Sea-to-Sky construction, sealing areas that are physically impossible to reach with manual methods.
Unlike many building envelope products, Aeroseal can be used throughout most of the construction season in Whistler and Squamish, with minimal temperature restrictions.
We coordinate directly with all major energy advisors in Whistler and Squamish, ensuring our process aligns with their testing protocols and documentation requirements.
