Johnson's Insulation

A well-insulated attic can make a dramatic difference in your home’s comfort and energy use. Quality attic insulation slows heat transfer, helping your home stay warm during cold months and cool during hot ones. Proper insulation also reduces energy bills, extends the life of your heating and cooling system, and prevents issues like moisture buildup or ice dams. Taking care of your attic is a small effort that delivers big rewards in efficiency, comfort, and home protection. What Is Attic Insulation and How Does It Work? Attic insulation is material installed in your attic to slow down heat transfer between your home and the outdoors. In cold months, it keeps warm air inside your home. In hot months, it prevents heat from seeping in.

Essentially, insulation acts like a thermal blan...
