WHAT IS THE AIR LEAKAGE OF R-CONTROL SIP STRUCTURES?
A. ORNL tested R-Control SIPs side by side with stick construction. The results were impressive – the air leakage from the R-Control SIP construction was less than 10% of the stick construction. This translates into a more comfortable structure with fewer drafts and lower utility bills. Q. SINCE R-CONTROL STRUCTURES ARE SO AIR TIGHT, DO THEY REQUIRE ADDITIONAL HVAC CONSIDE RATIONS? A. Yes. The increased R-value and lower air leakage means that heating and cooling equipment must be designed for a high performance structure. This translates into lower capacity heating and cooling units and most importantly lower cost units. Since R-Control SIP structures are so air tight, air exchangers are required as part of the HVAC system to bring fresh air into the structure while simultaneously exhausting air from the structure to ensure optimum indoor air quality. Comfort to the occupants is unparalleled. Q. HOW DO R-CONTROL SIPs HELP THE ENVIRONMENT? A. Many ways! The raw materials in R-Control S
