What is blue board foam?
Dupont Styrofoam™ Insulation (Blue Board) is a nonstructural, rigid board insulation manufactured of Extruded Polystyrene Foam (XPS). Blue Board can be used both on exterior and interior walls to give you a continuous insulation barrier that can increase effective R-value of the wall by up to 20%.
Is Blueboard insulation good?
Blue Board is available in a wide range of board styles, and thicknesses which share common characteristics. Being closed cell foam it makes a good insulator (typically R5 per inch) that is resistant to water damage and mold growth.
Is blue board insulation waterproof?
Foam board insulation products are generally considered water and mold resistant but expanded polystyrene foam boards (EPS) have air bubbles that can collect moisture and become wet.
Can you paint Blueboard insulation?
You can paint foam insulation as long as you use water-based acrylic or latex paint. Oil and solvent-based paints have chemicals that can damage the foam insulation.
Do you have to cover foam board insulation?
A: Yes, but to comply with building codes, all foam plastics must be covered with a 15 minute thermal barrier. Gypsum board, ½” thick is a common covering.
Do you need a vapor barrier with rigid foam insulation?
What I recommend to create a thermal break in basements is rigid foam insulation, with TUCK tape and no vapour barrier. Tuck tape all seams AND, be sure to use a spray foam in all the corners. You don’t need vapour barrier, and you won’t need to insulate between the studs.
Which foam board insulation is best?
Extruded polystyrene
Extruded polystyrene (XPS), also known as blueboard, acts as the best insulating foam board for below-grade applications, according to the U.S. Green Building Council. XPS offers greater moisture resistance than EPS, without the need for special films or coating to fend off moisture.
What is the R-value of blue board?
Extruded polystyrene foam (XPS) also known as blue board or pink board comes in many different thicknesses and edge profiles. This insulation board is probably one of the most widely used foam board insulation products in the residential construction industry. XPS has an R value of 4.5 to 5.0 per inch of thickness.
Is foam board a vapor barrier?
Rigid foam board, especially foil-faced polyisocyanurate, creates a vapor-impermeable barrier, so the wall would have limited drying potential. Even more permeable types of insulation, such as expanded polystyrene, are vapor barriers when the installation is thick enough.
What kind of paint do you use on foam board?
Acrylic Acrylic paint
Acrylic. Acrylic paint is ideal on foam core because you do not need to use solvents like with oil paints. Acrylic it fast-drying, durable and adheres to most surfaces. It also has an even sheen and does not need a base coat.
How do you cover rigid foam insulation?
There is no perfect material for covering and protecting exterior foam on foundations. Use metal or plastic reinforcing to strengthen the cement parging on foundation foam boards. The most common approach is to apply a stucco-like “parged” finish with a surface-bonding cement.
What is the best insulation board to use?
Extruded polystyrene (XPS), also known as blueboard, acts as the best insulating foam board for below-grade applications, according to the U.S. Green Building Council. XPS offers greater moisture resistance than EPS, without the need for special films or coating to fend off moisture.
What is the difference between pink and blue foam board?
Brand Names. Both pink and blue foam boards are rigid insulation panels made from extruded polystyrene.
What is the best insulation for house?
1) Spray Foam Insulation. This kind of insulation is done with aid of spray holders. Foam is sprayed from the containers in specific places of the house. 2) Fiberglass Insulation. This is the commonest form of insulation. They are available in either loose fill or batts. 3) Mineral Wool Insulation. Mineral wool insulation is also known as rock wool insulation. This is almost similar to fiberglass insulation. 4) Cellulose Insulation. If you are looking for some organic way to insulate your home, cellulose insulation will work best for you.
How do you install rigid foam insulation?
Install rigid foam insulation between the studs in new construction by cutting each piece to fit using a box cutter, table saw or circular saw. Press it into the cavity so that friction holds it in place. Use expanding foam or caulking to seal around the edges.
