Insulation is a key component in building construction, designed to control the transfer of heat, improve energy efficiency, and create a more comfortable indoor environment. It works by slowing down the movement of heat between the inside and outside of a building — keeping spaces warmer in the winter and cooler in the summer.

There are several types of insulation used in residential and commercial projects, including fiberglass batts, blown-in cellulose, rigid foam boards, and spray foam. Each type has its own advantages depending on the application, budget, and performance requirements.

In addition to temperature control, insulation also plays a role in soundproofing and moisture management within wall and ceiling assemblies.
