DELTA®-FOXX

The Problem

Unlike asphalt shingle roofs, which are nailed tight to the underlayment, tile and slate roofs allow air and moisture vapor to flow beneath them.

The Solution

Using a high-performance underlayment will allow moisture from within an unvented or highly insulated structure to diffuse outward into the ventilated space, preventing moisture accumulation.

DELTA®-FOXX is the highest vapor-permeable, water-resistive underlayment on the market today. It is a 2-layer roof underlayment, specifically designed for use with tile and slate roofs.
