Heating oil prices have risen 83% over the past year • natural gas has risen 42% over the past two years • and electricity has risen 17%. Most experts agree that these prices will continue to climb.
Buildings of the past were built without a lot of concern for energy conservation, mainly because we enjoyed low energy prices. But these are different times, and energy efficiency is a now financial decision that can’t be ignored. An energy efficient building pays you back for the life of the property.
A typical wood frame home has so many air leaks, it's like having a window open all the time, accounting for 25% to 45% of the total heat loss of the building. RASTRA provides Effective R-values up to R-48 with no heat loss caused by thermal breaks in the wall structure.
Every time fiberglass insulation meets a framing member, or breaks to accommodate plumbing, there is a break or gap in the insulating layer that allows air to pass. RASTRA virtually eliminates air leakage, creating more energy-efficient buildings. Any brand of insulation loses its ability to protect if it becomes wet and compresses from leaks or condensation from water pipes.
Wind pressure can increase the air infiltration even further, resulting in increased energy use. Information presented in ASHRE indicates that for a two-story wood frame house with 8’ ceilings, 20 mph winds can easily double air infiltration.
The best way to lower energy costs is to build a better exterior shell – one that provides high R-values, eliminates air leaks and retains conditioned air. In other words, a shell to keep conditioned air in and unconditioned air out.
RASTRA’s superior thermal performance, with an Effective R-value of up to R-48, and air tight panels greatly reduces heat loss and lowers energy consumption. By increasing the property’s true R-value with RASTRA, HVAC equipment operates less often, which also reduces energy costs. Improved climate control and less frequent exchange of air keeps air conditioners from working as hard to remove the humidity.
