AIR SEALING – THE MOST important factor in determining short-term AND long-term building performance and occupant health.
Why is air sealing THE MOST
important factor? Because buildings operate as a system.
Buildings are a big box – the building envelope - comprised of the Water Resistive Barrier, the Thermal Barrier, the Air Barrier and the Structural Assembly.
That big box houses little System boxes that deliver things like domestic hot water, space conditioning, space ventilation, entertainment, and SMART building analytic systems.
Each of those little System boxes operate more efficiently if the big box is effectively air sealed.
When the big box is effectively air sealed, you can get away with less insulation, lower cost windows, lower cost doors. You can condition the envelope using less power, ventilate the envelope with 100% HEPA filtered fresh air
vs. conventional buildings that rely on energy-hog space conditioning that blend as little as 10% fresh air with 90% re-circulated, pre-conditioned/re-conditioned , virus-laden air.
People occupying effectively air-sealed structures enjoy draft-free, constant temperatures. They breath fresh allergen-free air. They don’t hear or smell what’s going on outside unless they open a window or door. They have a better, healthier, quality of life.
Effective air sealing is THE key to a truly high-performing building. That’s why Build SMART is a stickler when it comes to air sealing.
Measured independently, SIPs panels are air-tight … but SIPs assemblies are not.
The secret to achieving air tightness in assemblies is how you transition from window-to-wall, door-to-wall, wall-to-foundation, wall-to-roof AND panel-to-panel connections.
Build SMART does NOT rely on pressure sensitive tapes or sealants of unknown chemistry or origin to achieve air sealing. We do NOT rely on mechanically fastened house wraps.
