What is the R value of ISO insulation?
For the R-value of polyiso wall insulation, a full thickness, 180 day aged value is recommended. Foilfaced polyiso has an R-value of about 6.5 per inch and permeability faced polyiso wall insulation has an R-value of around 6.0 per inch.
What is roofing ISO?
Polyisocyanurate thermal insulation, also referred to as polyiso, PIR, or ISO, is a popular low slope commercial building roof insulation. It is a thermoset, closed-cell foam that is an optimal insulation solution for low slope roofs. It can also be used as a roofing cover board and in building envelope applications.

What is the R-value of 2 inch IsoBoard?
Can you walk on polyiso insulation?
Commercial membrane roofs insualted with Type VIII EPS or 2lbs roofing polyiso typically rated 12-15 psi are considered “walkable”, with very limited PERMANENT deformation issues.
Can you stack polyiso insulation?
According to the Polyiso Insulation Manufacturing Association (PIMA), because multi-layering of polyiso provides a stronger, more rigid surface underneath the membrane one of the simplest advantages to using multilayers is the reduction in cracking or splitting of waterproof membranes.
What is IKO board?
IKO’s polyiso HD cover boards are constructed from a rigid, closed cell polyisocyanurate foam core bonded on each side to coated glass fiber facers during manufacturing. The product’s inherently high thermal properties and compressive strength make it perfect for use as a cover board.
How much R-value does polyiso lose?
Polyiso, it turns out, can lose as much as 25% of its R-value when the temperature drops.
Does polyiso lose R-value?
The trapped gases in the cells of polyiso and XPS foam assist to provide an initial high R-value. During the life of these foams, air from the atmosphere diffuses in and the trapped gases diffuse out. The result is polyiso and XPS lose R-value over their lifetime.
Is Polyiso breathable?
A coated glass fiber facer is laminated onto the board top and bottom, making it breathable. IKO Ener-Air offers a thermal resistance of approximately R6 per inch to improve the energy-efficiency of walls and ceilings.
What is Enerfoil insulation?
Enerfoil is a rigid polyisocyanurate insulation sheathing with a foil facer laminated on the top and bottom side. It is designed to be non-structural sheathing for cavity wall, stud walls or in cathedral ceiling construction. IKO Enerfoil Insulation Sheathing is dimensionally stable and can be sized with ease.
Is Coverboard required?
There are times that a roof system will choose not to have a cover board installed for a few reasons: Cost – you have the cost of the materials and the time/labor to install. Low Traffic – the roof system does not have a high amount of foot traffic or the need for high impact resistance.
How do I install Iko Enerfoil?
Fasten Enerfoil to wood studs with washered nails. Ensure that the fastener penetrates a minimum of 19 mm (3/4″) into the framing. Fasten Enerfoil to steel studs with washered mechanical fasteners. Attach Enerfoil against block wall with air/vapour barrier.
How do you install foil backed foam insulation?
To install foil insulation, roll it out parallel to the ridge and cut it with a utility knife, starting at the drip edge and working your way up. Overlap seams by about 3 inches. Secure the barrier to the roof deck with staples to prevent it from blowing off until you attach the battens and the roofing.
