What is R Value?

Published by Rease at 4:30 PM under Blog

 The term “R value” gets thrown around a lot when discussing construction, building materials, heating and cooling systems, and insulation. Everyone loves to tell you about their R Value, but if you don’t know what it means, what good is that information to you? Allow us to explain.

 

 

Quick definition

 
R value is a measurement of thermal resistance or heat transfer. The higher R value a building has, the more resistant it will be to heat flow. Building materials such as metal or glass have a low R value, while insulation has a much higher value.
 

Why should I be concerned about R Value?

 
As the definition states, the higher R value your home has, the more resistant it is to heat flow. Basically, a higher R value means better temperature regulation in your home and thus lower utility bills. Sadly, many builders only meet the bare minimum, so while they may try to impress you by throwing out arbitrary numbers, it’s important to recognize the difference between “standard procedure” R value and optimal R value.
 

How is R Value calculated?

 
R value is calculated based on the material. For insulation, the calculations are as follows:
 
Cellulose: 3.5 per inch
Fiberglass: 2.8 per inch
Rockwool: 3.2 per inch
Vermicullite: 2.7 per inch.
 
So, if you have 10 inches of fiberglass, you have an R value of 28.
 
Cellulose:
 

 

Fiberglass:                     

                                                                                                     

 

So what’s a good R value?

 
The “bare minimum” R value is R 38. However, based on our experience, we have found that most homes are only working with R 15. Sadly, neither of these values are what would be considered optimal. The optimal value varies by location, but in the St. Louis area, the recommended R value for optimal performance is between R45 and R60.
 
Chances are your home was built with the bare minimum and has since deteriorated down to R15 or lower. By bringing your R value up to optimal performance standards, you will be enhancing your home’s ability to regulate temperature, which means much lower utility bills and a more comfortable home.

Is Do-It-Yourself Attic Insulation a Good Idea?

Published by Rease at 4:21 PM under Blog

 

If you’ve decided to tackle your attic insulation issues to save money on your heating and cooling costs, you’re on the right track. Attics are very connected to your home and are often to blame for excess energy loss that ends up costing you more money on your utility bill.

Should I try DIY Attic Insulation or hire a professional?

There are plenty of people out there who are perfectly capable of fixing things around the house. When it comes to repairing a broken door hinge or fixing a leaky faucet, there is nothing wrong with doing it yourself. However, when the leak you are fixing is related you’re your insulation, the process can become a little more complicated. You’ll need to do an energy audit to figure out just how efficient or inefficient your current insulation installation is, check all your window and door seals, and perhaps even investigate the possibility of your insulation pumping polluted air into your home.
