The best insulation for walls when it comes to newly built homes or remodels will be Nu-Wool, foam boards or open-cell spray foam. The best insulation for walls depends on many circumstances. However, in the case of open walls where the budget is not a concern, sprayed foam insulation usually offers the greatest resistance to heat flow. Nu-Wool is known to be a premium cellulose insulation that is wet applied or installed in blocks.
Both blown cellulose and injected foam insulation can be installed from outside the house, so there is no need to remove any drywall. Loose fill insulation, also commonly known as cellulose, is a form of blow insulation used in attic floors and other horizontal structural spaces. Open-cell aerosol foam is an insulating material that creates continuous insulation and air sealing wherever it is applied. Owners of older homes filled with insulation material should call a professional to ensure that the insulation is not fiberglass with asbestos and, if so, that it is safely removed.
While standard insulation reduces heat flow in a home, reflective insulation reflects heat away from the home to prevent heat gain and radiant heat transfer to cooler indoor surfaces. Structural insulation panels (SIP) represented an important advance in the insulation of posts and beams and wooden structures. Whether you're building your dream home, remodeling your current home, or simply feeling like the insulation you have now isn't enough, you're looking for the best insulation for exterior walls. There are also different types of barriers that can be part of an insulating product or sold and installed separately to increase heat and vapor transfer across a wall assembly.
Whichever route best fits your home, whether it's done in conjunction with adding attic insulation or not, is a great way to reduce heating and cooling costs. This is one of the most economical types of insulation and is an easy-to-install product, as the materials are designed to fit the standard width between wall studs, attic beams and floor beams.
