What is R 50 insulation?
Conventional insulation requires thicknesses of up to 15″ to reach an R-Value of 50. R-50 Systems’ Rich-E-Board™ provides this same R value at 1″. The ultra-thin, lightweight design decreases costs of building modifications and structural retrofits, while creating more usable space for living and/or operations.
What is the best R-Value for insulation?
Depending on where you live and the part of your home you’re insulating (walls, crawlspace, attic, etc.), you’ll need a different R-Value. Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces.
What is R49 insulation used for?
The Owens Corning EcoTouch R49 Paperfaced Batts are used for roof/ceiling and interior/exterior wall applications and can be installed in wood or metal framing cavities or between furring channels.
Is R49 attic insulation worth it?
R-49 will do a good job of protecting your ceilings from the extreme inferno-like temperatures of 130-140 degrees in your attic. Think about it. If it’s 140 degrees in your attic, and you’re trying to hold 75 degrees inside the house, your attic insulation has to protect you from 65 degrees of heat gain.
What is the thinnest insulation with the highest R-value?
Aerogel insulation
Aerogel insulation offers the highest R-value of any insulating material at less weight and thickness—ideal for construction, refineries, pipelines, and thin-gap thermal barriers.
Is R49 good insulation?
What is the difference between R38 and R49 insulation?
A ceiling with an R-value of 38 lets through only 1/38 of the amount of energy per square foot that passes through that window, or about 2.6% of the energy; a ceiling with an R-value of 49 lets through only 1/49 of the amount of energy per square foot that passes through that window, or about 2.0 % of the energy.
