Rigid insulation boards might look strange at first sight. But they are very efficient and effective. Not only do they work similar to an air conditioning system, but also qualify as green solutions for reducing home energy costs.
Polyisocyanurate, extruded polystyrene, and expanded polystyrene boards are the three main types of rigid foam insulation. They all need to be sealed at corners and edges to be effective.
This is often made up of a combination of spray foam and tape. The rigid type of foam will need to be cut to size and then wedged into place for it to work. This is called a friction fit.
The material is also very flexible and can be glued with a variety of lightweight materials such as spray foam, caulk, and panel adhesive. It can be cut with a knife or saw too.
The size of a panel can be different. People usually use 2'x8' and 4'x8'. More than rigid foam, the panels will not shift or move out of place.
When it comes to costs, rigid foam insulation is more expensive than fiberglass or cellulose and can be also more challenging to install.
R-Value: 6.5-6.8 per inch- This is the most expensive of the rigid foam types, but it also has a ribbed pattern called foil or reinforced foil. It's also designed with an R-value range that is higher than other types of foam insulation.
R-Value of 3.8". This is one of the cheaper boards, but also the most easily damaged.
R-Value 5 per inch- This type of rigid foam is stronger than expanded Polystyrene and doesn't soak up water. This is the middle-priced variety and, because it's more workable, this is one of the most popular types of foam there is.
