•Falls in the middle of the three types of rigid-foam insulation in both cost and R-value •Used most in walls or below grade applications •Recyclable, and at about R-5 per inch, costs around 42¢ per sq. ft. for a 1-in.-thick 4×8 panel •Comes unfaced or with a number of different plastic facings


Foam insulation products and installation usually cost more than traditional batt insulation. However, foam insulation has higher R-values and forms an air barrier, which can eliminate some of the other costs and tasks associated with weatherizing a home, such as caulking, applying housewrap and vapor barrier, and taping joints. When building a ...


Polystyrene, often abbreviated as PS, is a plastic that is naturally transparent when it is developed. It is used in all types of applications, both as a solid material to be used with larger systems and as a foam material that can be applied in a number of different industries.


The most common insulation materials are fiberglass, cellulose and foam. Insulation types include loose fill, batts, rolls, foam board, spray board and vapor barriers. Tip: The type of insulation you need depends on which is currently installed and the required R-value.


High-pressure systems can be used to spray all three types of spray polyurethane foam. Of the three types of spray foam used in building insulation and weatherization, the high-pressure, two-component spray foam is most likely to be used on larger projects such as a new building construction or renovations.


The 2 Types of Spray Foam - Open Cell vs. Closed Cell The first thing you need to know is there are two different types of spray foam with different characteristics and applications. Open-Cell Spray Foam The cheapest spray foam option is known as open-cell. So called because the bubbles inside of the foam never completely close.


Insulation is used to make things airtight and save a person money on their energy bill. Walls, ceilings and floors that are well-insulated will keep cold drafts out during the wintertime, holding the heat in and causing lower energy bills. Different types of insulation also hold different R-values.


Because of this I often get questions about which type of foam board insulation to use and what R values these products provide. There are three basic foam insulation board products on the market produced under several different manufacturer names. The basic types of foam board insulation include: polystyrene, polyurethane or polyisocyanurate.


Materials commonly found in insulation are fiberglass, cellulose, and rock wool. A variety of different types of home insulation exist including: batts and blankets, loose-fill, plastic foam, rigid boards, and reflective. Each of these types has its own advantages and disadvantages.


Rigid foam board insulation. Rigid foam board insulation serves a variety of purposes, including structural strength, thermal break, exterior sheathing and serving as an air barrier in addition to insulating your home. Types of rigid foam board insulation include EPS (expanded polystyrene), XPS (extruded polystyrene) and polyisocyanurate.
