What is ISO board roofing?
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 Nailbase insulation?
Composite EPS Insulation Nailbase for Roofs InsulLam™ is an engineered insulation consisting of a closed-cell, lightweight and resilient expanded polystyrene (EPS) bonded to an APA/TECO-rated oriented strand board (OSB) or plywood.
Can you use foam board insulation on a roof?
All three types of rigid-foam insulation—expanded polystyrene (EPS), extruded polystyrene (XPS), and polyisocyanurate—are suitable for use on the exterior of walls and roofs, though they do not perform equally.
What is Nailable insulation?
Nailable Base-3, an all-in-one roof insulation and nailing surface, has a 7/16” thick OSB nailing panel bonded to a polyiso foam board with glass fiber/organic mat facers. It is designed for use with concrete, slate or clay roofing tiles, as well as wood shakes, asphalt shingles and metal panel roofing systems.
What is the R-value of 2 inch ISO board?
R-11.6
We commonly referred to it as ISO; the molecule that makes polyiso is polyisocyanurate. We are going to look into insulation R-value of polyiso….ISO R-Value Thickness Chart.
| Polyiso Thickness: | R-Value: |
|---|---|
| 1.5 Inch Polyiso | R-8.7 |
| 2 Inch Polyiso | R-11.6 |
| 2.5 Inch Polyiso | R-14.5 |
| 3 Inch Polyiso | R-17.4 |
What is the R-value of ISO board?
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 a nail base in construction?
A nailbase panel consists of a rectangle of rigid foam with OSB adhered to one side. While nailbase panels were originally developed for use on roofs, they are increasingly being installed on walls.
Which is better foam board or fiberglass insulation?
Made from polymers like polyurethane and polystyrene, rigid foam boards are denser, more expensive, and offer better resistance to heat flow than fiberglass. Conversely, fiberglass insulation is cheaper and more flexible, as it is made from raw materials like limestone, silica sand, and recycled glass.
Do you need to hit studs when siding?
Siding must be secured into metal studs if the substrate is not a nailable surface such as exterior dry wall, gypsum board, etc.
Why choose polyiso GAF insulation?
• Has zero ozone depletion potential (ODP) and negligible global warming potential (GWP) GAF provides high-performing, cost-effective solutions that can meet energy code and building specification needs while helping to protect your investment. Polyiso is one of the most commonly used and specified insulation types in the industry.
Why energyguard ™ barrier polyiso insulation?
Why EnergyGuard ™ Barrier Polyiso Insulation? EnergyGuard™ Barrier Polyiso Insulation is made of coated glass-fiber bonded to a core of isocyanurate foam and achieves an ANSI UL790 roof rating over combustible wood decks with a ½” board thickness.
What type of gypsum board can I use in my roof assembly?
DensDeck ® Roof Boards can replace any generic type X gypsum board in any roof assembly in the UL Fire Resistance Directory under the prefix.
