PlastiSpan® HD Insulation
Higher R-value and compressive resistance

PlastiSpan® HD Insulation is used in Cathedral Ceiling, Continuous ( Exterior Sheathing ), Exterior Foundation, Interior Basement Walls, Under Basement Floor, Hydronic System and Above Basement Floor.


PlastiSpan Insulation HD is a moulded expanded polystyrene (EPS)
insulation. EPS is a closed cell, rigid foam plastic insulation that does not
contain a blowing agent such as HCFC or HFC that provides a temporary
increase in thermal resistance.


• Meets CAN/ULC-S701, Type 2
• Thermal resistance - RSI 0.70/25 mm R-value 4.04/inch
• Compressive resistance: 16 psi
• Closed cell insulation resists moisture
• CCMC 12425-L


Continuous insulation eliminates thermal bridging, increasing your total
effective RSI/R-value. This reduces energy costs and increases your energy
savings.


CAN/ULC-S701-11, Standard for Thermal Insulation, Polystyrene, Boards
and Pipe Covering
is the National Standard of Canada for moulded
expanded polystyrene (EPS) insulation. The table below provides material
properties for PlastiSpan HD insulation meeting CAN/ULC-S701, Type 2.
