Wallbarn offers a range of leaf guards which help to ensure water drains efficiently from your rooftop.
 
When roof outlets are installed and properly bonded to the waterproofing membrane, it is essential that the holes do not become clogged up, which can restrict drainage and lead to standing water on the roof deck.
 
DOME SHAPED LEAF GUARDS

Our excluders come in zinc-plated iron, copper, stainless steel and plastic, and fit into all designs of circular / downpipe outlets and connectors and are compatible with all different manufactured materials.

They are designed with 12 rods at the bottom which have a slightly serrated edge, so that the leaf guard can be inserted into the hole and the edges will grip onto the inside of the drain connector or outlet, which has a series of small ridges around the inside rim of the shaft.

They are UV resistant and will withstand all normal chemicals in the atmosphere.

They can be fitted onto TPE, EPDM or PVC outlets easily without the need for fixings or bonding and can be removed and re-used without issue.

It is important to check the leaf excluders regularly and clean out the area around them.

GRAVEL EXCLUDERS

Our gravel excluders are available in plastic for use in circular drain connectors and roof outlets where the area is covered with a gravel or pebble layer (such as border edges or shingle ballast in an inverted roof system).

Made from polypropylene, they consist of a sturdy cage on the top with strong side bars and slats for the water to drain through.

We have two main designs: the Helix spoke (with three wide spokes) and the Spider fitting (with an angled four spoke design). Both these designs allow for installers to trim the spokes back easily using a sharp knife to fit the diameter of the outlet holes perfectly.

SQUARE LEAF GUARDS
Wallbarn now offers a strong, flexible plastic leaf guard designed for use with our range of corner / parapet / through wall outlets.

Made from a durable and hardwearing plastic compound, they fit securely into the mouth of the hole without the need for fixings or adhesive.

Square Leaf Guard

For right-angle faced outlets, both those with the square shaped mouth and those with the circular spigot, this RIGHT ANGLED SQUARE LEAF GUARD is ideal. The leaf guard has two prongs which will grip the inside of the spigot to ensure a good fit.

Although the square leaf guards are designed with straight sides, they can be used for both types of through-wall outlet – those with the right angled face and those with the 45° angled face and mouth.

For those outlets with a fillet-type angle around the mouth, the side arms can be cut with a sharp blade to create the 45° angle, giving a correct fitting. As these leaf guards are manufactured from plastic, they can easily be trimmed to alter the shape or reduce the size without affecting their performance.
