The following are some of the best insulating solutions for your attic bedroom.

The Spray Foam Insulation

This spray foam insulation has a huge R-value and it is water-resistant too. As a result, the unwanted heated air will be forced out of your home and you will have a cool environment in your attic bedroom.

The Blown Insulation

If you are a builder you can consider the blown insulation. You should make sure that it is installed properly. This type of insulation improves the energy efficiency of your attic bedroom. It decreases the production of carbon dioxide and utility bills too.

The mineral wool contains rocks and slag which are recycled from industrial waste. The fiberglass is made of recycled glass which is transformed into fibers. The following are some of the things you need to consider to benefit more on this type of insulation.

Find the correct R-value – the capability of a material to resist heat is measured by the R-value. The reason behind this is that these loose-fill insulation materials differ in the R-value. For you to attain the required level of insulation, you are required to work on them at different densities. You should also be able to adjust the amount of settling that might come up after some time and affect the R-value that you have installed.

At the back of your mind, you should have more knowledge about this type of insulation. For example, 20 percent of the R-value in cellulose is lost. So you will be required to work with an additional 20 percent more for your attic bedroom while installing. The percentage of settling for the mineral wool and the fiberglass will not affect the thermal performance.

No fluffing or gaps – if you install the insulation without considering the right density gaps will be formed in the attic bedroom. This will reduce the R-value. This also weakens the insulation effectiveness. To allow the heat and air to pass through it the installation thickness should be minimized.

Place it appropriately – loose-fill insulation is the best for your attic bedroom. This is because generally in the attic is where this insulation works best. Place the insulation at least three inches from your ceiling. To prevent problems to do with moisture and molds all you have to do is to install baffles and block the soffits.

Proper drying – ensure the loose-fill insulation gets enough time needed for it to dry. Note that if the cellulose insulation does not completely dry it might not reach the R-value requirements.
