Whether your house is brand new or has a lot of history, you should regularly verify the state of its isolation. The attic is the crucial spot to put insulation in your home. It can help you save money on the utility bills, increase the comfort of living, and prevent vermin from getting inside the building.

On the market, you can find two types of fiberglass insulation: blown and rolled. If you are not an expert, it can be unclear which type is the best for your attic.

Blown fiberglass can be spread with a special type of blower. It is a loose type of fiberglass. The plus of this insulation is its eco-friendliness. It is made out of recycled paper.

The R-value of blown fiberglass insulation is 3.2 to 3.8. That means it is better to cover a smaller area, while the rolled fiberglass insulation might be a better choice if you have to cover huge areas.

As the name suggests, rolled fiberglass insulation comes in rolls, also called batts. There is no need to use any special equipment to install this type of insulation. Unfortunately, that does not mean that installing rolled fiberglass insulation is an easy task. As it has an inconvenient size, weight, and shape, placing this fiberglass can be physically demanding.

The R-value score of rolled fiberglass insulation is 3.7. That suggests that this insulation type is slightly more efficient in blocking the heat from exiting and entering a building.

To install rolled fiberglass insulation, you do not need special knowledge. You can use it on the walls and cover the ceiling with it. Unroll it and stick it between the joists. However, because of all the inconvenience connected with unrolling the fiberglass, it is highly recommended not to do this job alone. Contacting an expert can help you save time and energy and avoid mistakes while covering the attic.

Blown insulation is often used to isolate walls and ceilings. It is more precise than rolled fiberglass and is a perfect choice if you want to seal holes in the walls or ceilings.

Blown insulation fiberglass is recommended to be used in attics. Rolled fiberglass is bulky, and it may be hard to place it in the attic. The long and heavy rolls are very hard to be brought and installed in attics.

Blown insulation is tricky

However, the blown insulation is much trickier to install than the rolled one. To add it to your place, you need to have specific knowledge and verify where all the obstacles, such as fire blocks, electrical wires, etc., are located. Obstructions should not be covered with blown fiberglass because if any issue occurs in the future, you would have to get under the insulation. After that, you would need to replace the broken insulation with a new one, which means unnecessary costs and extra work.

The layer of the insulation has to be even. Unfortunately, many people try to put it in themselves, and in effect, they under-insulate the house or even over-insulate it. That can lead to serious house problems. The households that do not have proper attic insulation can be affected by high energy bills, uneven room temperatures, high humidity, or even mold, in case the insulation layer is too big.

Because installing blown fiberglass insulation is difficult, it is not recommended to try it in a DIY style. You are doing the right thing by contacting experts who know exactly how to add insulation to your attic. By doing so, you save your time, money, and give yourself security that the insulation is installed properly.
