Roof cover boards have an Assortment of uses inside a roof system:
- Developing a Acceptable substrate for tissue installment
- Adding durability into the machine
- Enhancing impact immunity
- Limiting outside flame spread
- Adding to wind uplift resistance
- Developing a thermal barrier
- Developing a vapor barrier
Cover boards may be utilized in re-roof applications in which the plank is installed on an present roof system to deliver a substrate for the roof system.
There are instances a roof program will choose to not have a pay board
- Price – you’ve the Price of the substances and also the time/labor to put in

Cover boards could be set up by being mechanically secured to the deck or adhered the substrate. Finest practice for setup includes shocking the cover board’s joints and into the joints of their insulation beneath. This reduces openings and thermal bridging between layers.
Information on cover plank setup:

- A thermal barrier – that is when the cover board is set up straight to the deck to boost internal fire immunity.
- A substrate for a vapor barrier — a few cover boards have the capability to resist water
- A recuperate application – in which the board is set up directly to an present roof system to supply the right substrate for the new roof system.
Insulation may be flammable, therefore installing a cover board might help discourage the spread of fire from outside the building to the insulation and in your construction.
