Roof Protection Board R Value

It provides r values that range from 3 6 to 4 2 per inch.

Roof protection board r value. As we said before the r value measures the thermal resistance of a material. For instance if you have a material with an r value of 12 attached to another material with an r value of 3 then both materials combined have an r value of 15. Insulation level are specified by r value. This also means easy hoisting staging and maneuvering around the roof.

Insulation damage results in a reduction of the roof s thermal resistance or r value. 2 5 r value per of thickness. Some products have reinforced facing to make them sturdier. The higher the r value the better the thermal performance of the insulation.

Structodek hd with primed red coating is a high density wood fiber roof cover board with a proprietary red primer on two sides that provides an optimal bonding surface for single ply. Hail is damaging to insulation but by using a cover board the impact is minimized. Provides significantly more thermal insulation r value than wood fiber or gypsum boards. Provides significantly more thermal insulation r value than wood fiber or gypsum boards.

1 4 dens deck roof board. High r value 2 5 r. R value is a measure of insulation s ability to resist heat traveling through it. R values 28 tested in accordance with astm c518 spannings.

This also means easy hoisting staging and maneuvering around the roof. Protector hd allows easy efficient scoring cutting and snapping which permits fast tight fabrication and all in a low dust environment. These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation. For example if you have a type of insulation that has an r value of r 5 per inch of thickness you will need a depth of 6 inches of this insulation installed in your attic to reach r 30 if you live in zones 2 or 3.

The building is more susceptible to hail fi re and wind damage. Recommended home insulation r values. Without a cover board the roof is missing added durability. Protector hd allows easy efficient scoring cutting and snapping which permits fast tight fabrication and all in a low dust environment.

Choose this option for areas that need a good amount of strength and water resistance. It provides about r 5 per inch. R value is the measure. Cover boards can add strength and protection to a roofing system enhancing the system s long term performance.

The fiberglass mat faced noncombustible as described and tested in accordance with astm e136 nonstructural gypsum core panels provide superior fire resistance and protection from hail damage and hold up well under normal construction and maintenance foot traffic while stiffening and stabilizing roof decks.
