Narrow Drainage

A narrow or threshold drainage channel is a type of drainage system that is designed to control the flow of water through a doorway or another threshold, such as a garage door or a patio door. 

These types of channels are typically installed at the base of a door, and they are designed to channel water away from the interior of a building and out to an appropriate drainage area.

Narrow and threshold drainage channel benefits

There are several benefits of using threshold drainage channels. One of the primary benefits is that they can help to prevent water from entering a building, which can cause damage to the structure and lead to mould and mildew growth. 

Threshold and narrow drainage systems can also help to prevent ice and snow buildup, which can make it difficult to open and close a door and create a slipping hazard.

Another benefit of threshold drainage channels is that they are relatively easy to install and maintain. They are typically made from durable materials such as aluminium or stainless steel, and they can be customized to fit a wide range of door sizes and configurations.

All of the products we sell are compliant with British Standard building regulations and are manufactured from high-quality materials from exceptional and cutting-edge brands. 

Where can narrow and threshold drains be installed?

Threshold drainage channel can be installed at the entry door, patio door and also garage door. It can be used where there is a risk of water infiltration because the threshold channels can prevent water infiltration and protect the door or threshold. It can also be placed in areas where there is heavy rain or snowfall, where the risk of water infiltration is even greater.
