Provides significantly more thermal insulation r value than wood fiber or gypsum boards.
Roof protection board r value.
Recommended home insulation r values.
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.
Provides significantly more thermal insulation r value than wood fiber or gypsum boards.
High r value 2 5 r.
Hail is damaging to insulation but by using a cover board the impact is minimized.
It provides r values that range from 3 6 to 4 2 per inch.
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.
It provides about r 5 per inch.
Some products have reinforced facing to make them sturdier.
High r value 2 5 r.
These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation.
Protector hd allows easy efficient scoring cutting and snapping which permits fast tight fabrication and all in a low dust environment.
This material offers the highest r values about r 6 to 6 5.
Without a cover board the roof is missing added durability.
The building is more susceptible to hail fi re and wind damage.
Choose this option for areas that need a good amount of strength and water resistance.
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 higher the r value the better the thermal performance of the insulation.
1 4 dens deck roof board.
Insulation damage results in a reduction of the roof s thermal resistance or r value.
This also means easy hoisting staging and maneuvering around the roof.
1 4 spans flute widths up to 2 5 8 flexural strengths parallel lbs.
Protector hd allows easy efficient scoring cutting and snapping which permits fast tight fabrication and all in a low dust environment.
R value is a measure of insulation s ability to resist heat traveling through it.
2 5 r value per of thickness.
R value is the measure.
R values 28 tested in accordance with astm c518 spannings.
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.
