If you’re going to insulate 2×4 walls, it is important to know what the appropriate thickness should be. The question is all the more critical when one considers that these assemblies and insulations are permanent. This is because once the walls are insulated and sealed up, it is not an easy task to change them out.
Too little – or too much – insulation leads to a colder house than is necessary. The air pockets within the insulation are what work to keep a home warm, not the fiberglass. It is essential then to get a fine balance between too little and too much insulation to keep your family warm during the winter period.
Another important feature to consider when selecting the best insulation for 2×4 walls is the sound dampening capabilities. This is an essential component when maintaining calm and peace inside the house by dampening the noise.
Many of the products available in the market also ensure that they are water-resistant, which ensures that there is no danger of mold or mildew growth. This ensures that the air quality of the house is maintained.
There are hundreds of products available in the market that can really make the buying process an ordeal in itself. That is why, in order to make the process a little easier, in this article, we take a look at three different products that are perfect when it comes to providing the ideal thermal insulation to your house.
