More Information
The Heritage Dry Valley is made of GRP (Glass Reinforced Polyester) for added durability against weather and discoloration, which makes it a great choice of material for a valley, however, it's the shape of this product that makes it truly innovative.
The shape of the Heritage Valley has a unique ‘S’ design, allowing a narrow span between tile support ledges, ensuring a 35% wider drainage channel. This means that in order to get a close mitred finish on the roof tiles, also known as a ‘Stitched Valley’ finish, you do not need expensive lead soakers between each slate course, making an easier installation and more cost effective method of getting a superior traditional mitred valley finish.
