How thick is cover board on a roof?

Coverboards are typically thought of as 1″ thick or less, dense boards that provide sound and fire resistance to the assembly.

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 the difference between DensDeck and DensDeck prime?

DensDeck roof board is a patented glass mat faced, noncombustible, nonstructural, moisture resistant treated gypsum core panel. DensDeck Prime® roof board combines all the features of standard DensDeck roof board with an enhanced surface treatment.

Is DensDeck waterproof?

The patented DensDeck® design employs glass mat facings front and back that are embedded into a water-resistant gypsum core providing excellent fire resistance, moisture resistance, and wind uplift properties.

What is thicker 60 mil or 45 mil?

(A mil is a unit of measure where 1-mil is equal to 0.001 inches. So, a 45-mil roofing membrane is actually 0.045 inches thick; whereas a 60-mil membrane is 0.06 inches thick, and so on.)

What is the R-value of 2 inch ISO board?

What is the R-value of 2 inch IsoBoard?

What is the R-value of IsoBoard?

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.

Can you walk on DensDeck?

Allow primer to dry before walking on the DensDeck Prime substrate. Cover the membrane with the exposed roofing material as soon as possible.

Can you torch directly to DensDeck?

What is DensDeck used for?

DensDeck is used primarily in mechanically fastened roofing applications as an overlayment board in lieu of high density wood fiberboard over insulations such as extruded polystyrene or EPS and over polyisocyanurate insulation when additional compressive strength is desired for roofs subjected to increased foot traffic …
