Does Insulation Installation Really Matter?

When it comes to insulation installation, the general rule is that the coating should always be placed against the drywall to act as a vapor barrier. Most fiberglass plates have a kraft coating which is classified as a Class II vapor retarder, and this should be oriented towards the warm side of the assembly during winter. In climatic zones where an interior vapor retarder is required, the kraft paper coating should be facing inward. Installing insulation is a relatively straightforward process that doesn't require any special skills or strength.

The rolls or bars should fit snugly between the uprights, and all you need to do is trim around windows, door frames, electrical outlets and pipes. It can be easily cut with a multi-purpose knife and is very lightweight. It's important to consider whether it's necessary to install fiberglass blocks with the paper support at the bottom, between the warm part of the house and the insulation, or if it's acceptable to place the paper support in the cold part of the attic. This is because if the insulation is installed with the paper vapor barrier facing away from the warm part of the house, moisture from the humid indoor air can condense and be trapped in the insulation during cold winter months. This can lead to mold growth and other issues. To ensure that your insulation installation is done correctly, it's best to hire a professional contractor who has experience in this area.

They will be able to assess your home and determine which type of insulation is best for your climate and needs. They will also be able to install it correctly so that it provides maximum energy efficiency and protection from moisture. In conclusion, insulation installation does matter when it comes to energy efficiency and preventing moisture buildup in your home. It's important to hire a professional contractor who has experience in this area so that your insulation is installed correctly and provides maximum protection.
