We keep talking about this R-Value, but you may not know what it is. Here's a simple explanation:
The "R" in R-value stands for "resistance"; resistance in the movement in temperature through your walls and ceilings. You need to know that you are buying high R- Value rated insulation. The higher the R- Value, the greater the resistance to temperature moving through your walls and ceilings. You want as high a resistance as possible to stop the leakage of air from inside your walls.
The highest R-Value in a retrofit stud wall application is 5.1 per inch. This is a rating that has been achieved by USA Premium Foam and you can rest assured that by using this product you cannot get any better insulation. This is also the case for our attic insulation. By using Johns Manville formaldehyde free insulation products, you will have a safe and cost effective solution to your insulation needs.
It might be hard to believe, but recent studies by the U. S. Department of Energy, show that only 20% of houses that were built before 1980 are up to snuff when it comes to insulation. Many properties do not have any insulation at all, as historically it was not a requirement of new building projects. There is so much to be gained from good insulation and you can find out more through our pages. Contact us today for your free energy consultation.
In order to build a new home today, it is mandated, that in all parts of the country, all homes must have minimal acceptable R-Values:
These recommendations are cost-effective levels of insulation based on the best available information on local fuel and materials costs and weather conditions. Consequently, the levels may differ from current local building codes. In addition, the apparent fragmentation of the recommendations is an artifact of these data and should not be considered absolute minimum requirements.
