The higher the R-value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate an R-38 or approximately 10 to 14 inches, depending on the type of insulation. When it comes to how thick insulation should be, there is no one-size-fits-all answer. Several factors influence how much insulation an attic needs.
Energy Star recommends approximately 10 to 14 inches of insulation for most attics, but you may need more or less than that. The standard R-value range for block and roll insulation is between 2.9 and 3.8 per inch. Some high-density glass fibers can reach R-values of 4.3 per inch, making thicker varieties sufficient for most climates. Once you've finished assembling the roof, you'll have numerous insulation options available to place under the attic cover.
You can find it on the basketball court or on the golf course when you're not trying to teach others about spray foam roofing and silicone roof coverings. In addition to being a type of insulation that is relatively easy to install on its own, it can provide a natural acoustic barrier, effective protection against condensation, and flame-resistant shielding for the roof. For spray foam ceilings, the goal is to maximize the R-value (so you can reduce your energy bills), but recognizing when adding foam won't save you money. Some of the owners who worked with McLean Roofing and Siding 20 years ago are now returning to do more business. Since 1979, we have been developing custom-designed spray foam roofs that offer the highest R-value, with the lowest possible installation cost.
McLean Roofing and Siding can recommend the best type of insulation for your home during your consultation. This is because with any roof with gravel accumulation, you'll need to use a wet vacuuming system to remove loose dirt and gravel from the roof. When combined with your roofing system, these insulation options should provide varying degrees of protection from the elements. If the slope is integrated into the roof, a minimum of 1.5 inches of spray foam can be installed and then drain mounts placed between the drains to facilitate water flow.
You may need to hire a roofing or insulation professional or contractor to help you with the application process, but the added cost and versatility of this type of insulation are well worth it. The current owner of McLean Roofing and Siding is James Broecker, nephew of the company's original owner. Here, we describe the different types of insulation to make it easier to choose the material, the positives and drawbacks of each type of insulation, how much insulation costs, and how to choose the best insulation for your roof and attic. The most beneficial installation is an inch near the drains and 2 inches away from the drains, resulting in the roof averaging 1.5 inches of spray foam.
There are times when there is too much saturation in the current roof, so it's best to remove everything that's left on the roof and start over.
