Why Are Flush Threshold Drains The Best Choice For Your Sliding Doors ?

Slidingdoors and bi-fold doors have enjoyed a huge rise in popularity in recent times as homeowners look to create seamless connections between internal and external living spaces. When looking to embrace this modern trend, threshold drains are a key design feature that deserves your attention.

Here at Aquabocci, we supply homeowners and sliding door companies with a range of door threshold drain solutions including the award-winning R-47
x Blade . Let’s take a look at why adding a low profile threshold drain or threshold slot drain to your system should be high on the agenda.

Bi-fold Door Threshold Drainage Works Efficiently

When considering door threshold drain options, you will naturally seek an attractive solution that also offers value for money. Before worrying about this, though, you must check that any threshold drain must function as expected. When you do, the need to choose a drain that will drain the water from your door track, becomes clear.

The UK sees average annual rainfall of 800mm to 1400mm, the big question you have to ask is simple: do all types of channel drain products actually stop water from getting inside your home ?

Dedicated bi-fold / sliding door threshold drainage channel products deliver the best solution on the market. By integrating with the weep holes that are found within the track of the door system, the R-47 Threshold Drain will effectively collect the water and redirect it to the groundwork pipes and away from the property. This is achieved courtesy of a side entry and membrane sleeve.

As well as providing a flush threshold drain for doors that looks great, it stops water from finding its way into the home. This subsequently stops water damage to the track or other parts of the sliding doors, as well as the flooring on the internal side of the door. Avoiding moisture also reduces the risk of mould growth.

Aside from protecting your property, an efficient drainage threshold will save you from having to wipe a towel around the bottom of the sliding door. For added convenience and comfort, a threshold drain channel is the best choice by far.

A Threshold Drain Provides A Seamless Aesthetic

Bi-fold door systems and sliding doors offer many benefits increased energy efficiency and improved flow between internal and external areas. However, a door threshold drainage channel is one that sits directly beneath the track also provides a seamless aesthetic.

Firstly, a flush threshold drain for doors connecting internal and external spaces is not really seen due to their positioning. Moreover, slot threshold drains can be cut to any size, which subsequently means that they may be used with any sliding door or bi-fold door structure.

A threshold drain channel that integrates with the track allows you to create a level look that makes patios and other outside settings look even better. On a side note, removing the step down into the garden area also removes a potential trip hazard for, children and older relatives. So, it’s an ideal choice for safety as well as aesthetics.

Whether the sliding door is open or shut, threshold drains are a great choice that provides a visually pleasing finish to your project - not least because those benefits can be enjoyed from both the inside looking out and the outside looking in.

Crucially, a threshold drain channel can incorporate corner sections to provide even greater aesthetic flexibility. Meanwhile, the spigots can be positioned anywhere to connect with 50mm or 110mm pipes.

A Door Threshold Drainage Channel Is Cost-Effective

Research suggests that a patio door replacement in the UK can be expensive, while new installations and designs will fluctuate in price depending on size and the complexity of design. Either way, it’s a significant project that requires attention. When looking for added value, sliding door threshold drainage are vital.

A door threshold drainage channel will increase the cost of the project, but not by a huge amount when considered as a percentage. Crucially, the fact that it supports the longevity of the doors while also protecting the areas on either side of the entry point will save you money in the long run. Not least because Aquabocci is an experienced supplier that works with products that feature a durable EPDM Membrane capable of satisfying your needs for years to come.

It’s also important to remember that time is money. Frankly, the fast assembly fitting system with internal and external corner pieces also saves you money on labour costs. Moreover, our bi fold door drainage threshold solution services allow homeowners or contractors to select the exact products that they need. This includes end caps, spigots, connectors, and even glue. When combined with the cut-to-specification section lengths, wasting money on unnecessary threshold slot drain features is not an issue.
