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.

Rigid insulation slope to roof drain dimensions parapet.

Max baker and stonewall jackson would be proud. The cure for parapetitus is continuity of the control layers and letting things move when they have to move. Built up roofs shall have a design slope of not less than one fourth unit vertical in 12 units horizontal 2 percent slope for drainage except for coal tar built up roofs that shall have a design slope of not less than one eighth unit vertical in 12 units horizontal 1 percent slope. Because of its size and customization options tapered eps often can be installed in a single layer.

As a general rule if the insulation is two inches thick or less a 4 foot by 4 foot sump is sufficient. The standard tapered panel size is 4 x 4. If the insulation reaches three inches or thicker an 8 foot by 8 foot. Higher r values mean greater insulating power.

Find out why in the seller s fact sheet on r values. The perimeter of the roof assembly insulation is wrapped to prevent interstitial airflow from the parapet into the multilayered rigid insulation of the field of the roof. As a general rule if the insulation is 2 thick or less a 4 by 4 is sufficient. If the insulation reaches 3 or thicker an 8 by 8 creates a more gradual slope while still providing the necessary momentum.

A typical interior roof drain assembly occupies about a 4 by 4 square area with a per foot tapered slope. 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. Localized drainage at drains.
