Rigid Insulation Slope To Roof Drain Dimensions
Tapered expanded polystyrene eps roof insulation was developed more than 30 years ago with a dual purpose in mind.
Rigid insulation slope to roof drain dimensions. The standard tapered panel size is 4 x 4. Over the course of the roof system the tapered insulation will create a slope toward the drains which typically ranges from 1 8 slope 1 down every 8 to slope 1 down every 2. 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.
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. Tapered roof insulation systems are designed to provide a 1 savings vary. Higher r values mean greater insulating power. Gradually tapered sumps formed in the insulation to facilitate localized drainage at drains.
If the insulation reaches 3 or thicker an 8 by 8 creates a more gradual slope while still providing the necessary momentum. To drain and insulate dead level roof decks. Because of its size and customization options tapered eps often can be installed in a single layer. The first piece may go from 1 high to 1 high then the next piece will go from 1 high to 2 high.
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. 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. 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.
