Due to their durability and longevity, metal roofs have become an increasingly popular option for homeowners. If your company is expanding its roofing material selection, it is important to have the right kind of insulation to help your clients conserve energy and decrease outside noise. Here are the best types of insulation for a metal roof.

A Guide to Common Metal Roof Insulation Materials

1. Rigid Board

This type of insulation is used throughout the home, from the walls and roof to the foundation. Rigid boards are made from panels of polyurethane or polystyrene and come in sheets of varying sizes. The thicker the board, the higher the R-value, which measures how heat-resistant the material is. 

During roofing insulation, the boards must be fitted tightly together and the joints should be calked or sealed to maximize thermal resistance. They are placed directly under metal roof panels. Rigid boards are dense and thin compared to other insulation options, so they can be installed with fewer joints and gaps to minimize air leakage.

2. Fiberglass Batts

Fiberglass is a material made from pieces of fine, thread-like glass woven tightly together with other synthetic materials to form a thick pad. It is a low-cost option and quick to install, which many homeowners will find appealing.

Despite its low price point, fiberglass insulation has a similar R-value to other types of insulating materials. The material is also very versatile. You can cut it however you need to fit surfaces of all shapes and sizes, then install it underneath the metal roof panels or onto an already completed roof.

3. Spray Foam

This self-adhering material is a form of polyurethane insulation that is applied as a heated liquid. When it reacts with oxygen, it expands, hardens, and cures. The result is a thick, rigid foam that prevents condensation and keeps out rodents, insects, and other pests. Spray foam is a highly effective insulating material for metal roofs, and it is very easy to work with. It can be applied to old and new rooftops alike.
