The importance of properly installing fiberglass insulation is a no-brainer. If it's not installed correctly, you can end up paying for expensive home repairs and dealing with uncomfortable living conditions.
To get the best R-Value, batts of fiberglass need to be properly placed without any empty or misplaced spaces. The usage of batts in electrical boxes is often overlooked for this reason.
When it comes to insulating a wood-frame home, a polystyrene batt that's made for the spacing between studs, joists & rafters is your best option. There are several thicknesses and width options to choose from depending on the type of wall you have.
Faced insulation is sold either with facings of either kraft paper, foil-faced kraft paper, or plastic. Keep it facing the inside rather than the outside.
Fiberglass is everywhere, partly because it's cheap to install & easy to find the materials for. It couldn't hurt that there are countless ads about how great fiberglass is.
With easy-to-use tools, installing fiberglass insulation in your home is not only fast but also provides substantial energy savings.
It is hard to complete a job with gaps in coverage or even a very small missing area, reducing its R-value by over 50%.
One of the major disadvantages to using fiberglass insulation is that its R-value drops substantially when it is fluffed, compressed, or wet. Basements are an even worse match for these batts because they have moisture issues and are more likely to be exposed to mold.
I also found that Fiberglass is unable to seal in any case, no matter how well it's placed. To get maximum R-Value, the fiberglass batts have to be placed in an area with very little air leakage
Improve all wood-framed walls that have no insulation or poor insulation by injecting foam into the wall cavities.
First, there's Dense-pack cellulose and the second is injection foam. Both methods have been used more and more as people consider their energy bills.
The installation of new insulation materials includes the drilling of access holes before the crew starts to inject materials into these openings. This prepares for an easy and quick installation.
Usually, these are injected into the stud cavities. Foam or cellulose insulation is then pumped into each one until it's full. All plumbing vents are sealed on the dirt floor when the cavity is full.
When there is foam, the air in the cavities is eliminated and natural gas consumption (mostly for such equipment such as furnaces) is reduced by up to 50%.
