Rigid Insulation Slope To Roof Drain Dimensions

Simplifying the job with eps in contrast tapered expanded polystyrene eps rigid foam insulation is available in blocks up to 40 inches thick and can be cut to virtually any slope depending on the drainage needs of the building.

Rigid insulation slope to roof drain dimensions.

Manufactured from lightweight foam control eps tapered expanded polystyrene eps roof insulation is a value engineered system that has been proven in new and reroof applications all over the country. To drain and insulate dead level roof decks. Tapered roof insulation systems are designed to provide a 1 savings vary. Tapered rigid insulation is polyisocyanurate insulation or eps insulation custom manufactured to provide a slope.

As a general rule if the insulation is 2 thick or less a 4 by 4 is sufficient. Gradually tapered sumps formed in the insulation to facilitate localized drainage at drains. The standard tapered panel size is 4 x 4. The first piece may go from 1 high to 1 high then the next piece will go from 1 high to 2 high.

Minimum slope of per foot as required by the international building code ibc toward roof drains or scupper drains leaving no fl at areas for ponding. Higher r values mean greater insulating power. If the insulation reaches 3 or thicker an 8 by 8 creates a more gradual slope while still providing the necessary momentum. Over structural slope when roof drains are located a great distance away from a sloped roof edge more than 48 it can be more cost effective to use a tapered backwash.

Find out why in the seller s fact sheet on r values. A typical interior roof drain assembly occupies about a 4 by 4 square area with a per foot tapered slope. As a general rule if the insulation is two inches thick or less a 4 foot by 4 foot sump is sufficient. A typical interior roof drain assembly occupies about a 4 foot by 4 foot square area with a inch per foot tapered slope.
