SIPLOCK. “Changing the building Paradigm”




According to, the 2006 IECC, the design effectiveness of all high-energy efficient

construction directly affects the HERS rating.


  • Air leaks in a building envelope


Oak Ridge National Labs has stated that 40% of heat loss or gain is due to air leakage.

SIPLOCK insulated panels’ flash one another with a factory-milled tongue and groove

joint. Panel walls and roofs are designed to be airtight.


  • Air leaks from HVAC distribution ducts


SIPLOCK closed envelope design places HVAC ducts in conditioned spaces,

considerably reducing the effects of air duct leakage.

SIPLOCK permits the use of Ductless HVAC, eliminating the effects of air leakage.


  • Effectiveness of insulation in walls and ceilings


SIPLOCK wall and roof panels are constructed of EPS.

Panels are rated at R46 (roof) & R38 (wall).

IR energy reflective 26-gauge Galvalume steel clad SIP.

Siplock design “breaks” conductive thermal bridging.

EPS is water and moisture resistant.

Oak Ridge National Labs has stated that the individual R-value of each insulation and

construction component they evaluated had very little to do with the R-value of an entire

wall or roof assembly. In fact other studies have indicated that 30% of a buildings Heat

loss or Heat gain is from conductive thermal bridging. SipLock wall and roof panels

eliminate the effects of thermal bridging.


  • Floors over garages and crawl areas


SIPLOCK insulated panels are set down to the grade slab or footing.

Insulated space i.e.; garages or crawl areas under conditioned rooms is now considered

“semi-conditioned space”. Note: In a SipLock designed building, the semi-conditioned

space generally has a 5-8 degree temperature differential from the “conditioned” space.


  • Air leaks in Attics and crawl spaces


SIPLOCK panels flash one another, creating an airtight & weatherized seal. SIPLOCK

closed envelope design eliminates the need for “ridge”, “soffit” and “crawl” vents.

Improved HERS rating: No vents. No Air-Leaks. No Heat Gain. No Heat Loss.
