What is the R-value of polystyrene?
What is the R-value of polystyrene?
around R-3.8 per in.
Expanded polystyrene: Expanded polystyrene (EPS) is the least-expensive type of rigid foam and has the lowest R-value (around R-3.8 per in.).
What is the R-value of DuroFoam EPS rigid insulation?
3.75 per inch
With an R-value of 3.75 per inch, DuroFoam insulation is ideal for adding energy efficiency and cost savings to any project. It is easy to install and can be used in many applications; exterior sheathing, continuous insulation, basement floor, under slab insulation and cathedral ceilings.
Is EPS good insulation?
EPS (Expanded Polystyrene) This means that it is rigid foam, so is ideal for securing to external walls. EPS is 90% air because it is not very dense – the fact that it is made up of lots of small polystyrene beads means that there are lots of tiny air pockets. This is what makes it a great insulator.
What is Type 2 EPS insulation?
PlastiSpan HD Insulation is a Type 2, moulded expanded polystyrene (EPS) insulation with an R-value of 4.04 per inch and compressive resistance of 16 psi. PlastiSpan HD is a versatile insulation product that can be used in a wide range of applications.
Is DuroSpan GPS a Vapour barrier?
Vapour Barrier System Requirements Although DuroSpan GPS insulation has a vapour permeance less than 30 ng/(Pa•s•m2), it is attached to the exterior (cold side) of above grade walls.
What is the RSI value of plastispan HD type 2?
The closed cell insulation resists moisture, with thermal resistance – RSI 0.70/25 mm R-value 4.04/inch. CCMC 12425-L listed. Continuous insulation eliminates thermal bridging, increasing your total effective RSI/R-value. This reduces energy costs and increases your energy savings. Not Finding What You’re Looking For?
What does the are value of EPS insulation mean?
R-value means the resistance to heat flow. The higher the R-value, the greater the resistance to heat flow. When properly installed and protected from moisture, the R-value of EPS insulation remains constant.
What is the thermal resistance of plastispan insulation?
PlastiSpan Insulation HD is a moulded expanded polystyrene (EPS) insulation with a higher R-value and compressive resistance of 16 psi that meets CAN/ULC-S701, Type 2 requirements. The closed cell insulation resists moisture, with thermal resistance – RSI 0.70/25 mm R-value 4.04/inch.
What kind of code does plastispan insulation meet?
By increasing your energy efficiency with PlastiSpan insulation, you will effectively reduce your heating and cooling costs. PlastiSpan Insulation is code listed with CCMC 12424-L and meets the requirements of CAN ULC S701.1, Type 1. Other Standard & Custom thicknesses available upon request.
