Insulated Wall Assemblies

T-Stud

The Tstud™ is an engineered building product that uses two lumber members, and an internal truss system to break the thermal bridging common with solid wood wall studs and plates. Two versions are available. The pre-insulated version comes with low-GWP foam insulation in the truss section giving the product an insulating value of R-19. The Barenaked version leaves outoff the foam, so that dense pack insulation can be installed on site. T-studs are currently available in 2x6 and 2x8 thicknesses.

Structural Insulated Panels (SIPs)

Structural insulated panels (SIPs) are a high performance building system for residential and light commercial construction. The panels consist of an insulating foam core sandwiched between two structural facings, typically oriented strand board (OSB).  SIPs are manufactured under factory controlled conditions and can be fabricated to fit nearly any building design. The result is a building system that is extremely strong, energy efficient and cost effective. Building with SIPs will save you time, money and labor.

Are Structural Insulated Panels More Expensive?

Building with SIPs generally costs about the same as or less than building with wood frame construction when you factor in the labor cost savings resulting from shorter construction time and less jobsite waste.  Other savings are realized because smaller heating and cooling systems are required with SIP construction.

SIPS are Ideal for Zero Energy Construction

SIPs provide insulated, air-tight construction, with lower costs for getting to zero net energy than traditional stick frame construction. All SIPs manufacturers have had net zero projects and most SIPs projects are HERS rated in the 35 - 45 range pre renewables. The Rocky Mountain Institute’s Innovation Center used SIPs for their new zero energy commercial building, and SIPs are ideal for zero energy homes as well, such as this single family home in Houston.
