Energy Efficient Building Envelope

(structural insulated panels)

 

Timber Masters provides energy and building efficient wall and roof panel systems. Structural Insulated Panels (SIPs) are high-performance panels made by sandwiching a core of rigid foam plastic insulation (EPS) between structural skins of various types, most common of which is oriented strand board (OSB) or plywood. For additional protection, panels can be upgraded to MGO panels, giving more weather resistance, mold & mildew resistance, and up to a four hour fire rating. These panels are ideal for back-country cabins and other structures that can be threatened by wildfires, high moisture locations, or areas with more extreme weather.

Because they are factory-made, SIPs can be custom-designed to the needs of each project.

Advantages of SIPs include:

  • SIPs cuts overall construction time of project because of pre-fabrication assemblies.

  • Weather-tight and security-locked within days.

  • Factory precut panels cuts down wastage.

  • SIPs are stronger than standard framed walls and roof truss systems.

  • Buildings built with SIP framing are more energy efficient than stick-built homes.

  • HVAC system is smaller than non-SIP homes.

  • Trim and cabinet installation easier because of the straight walls.

  • Mold and mildew resistant.

  • Electrical chases are pre-cut at factory.

  • A friendly product for the do-it-yourselfer

  • Strong fire protection and ability to prevent fire spread (no air cavities).

Faster Construction

  • SIPS are ready to install when they arrive at the job site, eliminating the need to perform the individual operations of framing, sheathing, and insulating stick-framed walls. This saves builders significant amount of on-site labor.

  • Add more projects to scheduled builds.

  • The fully insulated SIP enclosure makes winter finishing quicker.

  • A shorter building cycle of the structure translates to lower loan cost overhead.

Ease of Construction

  • When skilled labor is at a premium, SIPs allow experienced or inexperienced crews to put up building envelopes quickly, shaving days off building enclosure schedules.

  • Training and consultation is provided for first time installers.

  • Detailed project installation details are provided.

Building Code Compliant

  • Unless municipality requests, SIP CCMC approved wall panels do not require engineering for 6 1/2” walls up to 10’ high.

  • 6 1/2” SIP wall exceeds recent Alberta and BC building code 9.36 energy code requirements.

Energy Efficient Building

  • The insulating core of a SIP provides high density continuous insulation. Excess RSI allows for trade off in building design.

  • SIPs are up to 15 times more airtight and when combined with other energy efficient technology are 50% more energy efficient than stick building.

  • SIP houses are frequently measured at 0.2 air changes.
