What is the density of polyisocyanurate?
2.5 lb/ft³ (40 kg/m³) density.
How thick is R25 Polyiso?
The high R-value and light weight of high-density (HD) polyiso cover boards provide important contributions to the design of a durable roof system. A typical 0.5” thick HD polyiso cover board adds R-2.5 to the total R-value of the roof insulation system.

What is R-value of Polyiso?
about 6.5 per inch
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 Coverboard?
A cover board is a thin substrate to which a roof membrane is adhered. However, the use of a cover board far exceeds that of a substrate — it also serves as a critical component that helps to extend the life of a roof.
What is the density of expanded polystyrene?
EPS has a reduced thermal conductivity, with a density of about 28-45kg/m3. It therefore acts as an insulator keeping products cold or warm depending on the application.
What is the R-value for 2 rigid insulation?
With an R-value of 13.1 for a 2″ thick sheet only two 2″ sheets are required to achieve R-25. 2. Extruded polystyrene or XPS (foam is usually pink or blue) XPS has an R-value of 5 per inch of thickness requiring 5″ of insulation to achieve R-25.
What is the R-value of 2 rigid foam insulation?
Foam board insulation R-value varies based on type but is anywhere from 3.6 per inch of insulation thickness to 8.0.
What is polyiso insulation?
Polyisocyanurate (polyiso) is a closed-cell, rigid foam insulation board made with recycled content that is widely used in commercial roofing. Why Polyiso insulation? Polyiso insulation is the best choice as a cost-effective, energy efficient and environmentally responsible insulation product.
What is the density of dyplast insulation?
2.5 lb/ft³ (40 kg/m³) density. ISO-C1/2.5 is Dyplast Products’ 2.5 lb/ft³ polyisocyanurate rigid, closed cell, foam insulation. ISO-C1/2.5 is certified by independent laboratory to meet demanding Class 1 flame spread and smoke development requirements per ASTM E84.
What is isoiso-HT insulation?
ISO-HT is Dyplast Products’ 2.5 lb/ft³ polyisocyanurate rigid, closed cell, foam insulation for higher temperature applications up to 350°F (177°C), with intermittent exposure up to 375°F (190°C).
What is the density of ISO C1 insulation?
ISO-C1 ®/2.5 Polyisocyanurate Insulation. 2.5 lb/ft³ (40 kg/m³) density. ISO-C1/2.5 is Dyplast Products’ 2.5 lb/ft³ polyisocyanurate rigid, closed cell, foam insulation.
