Understanding Integrated Drainage Systems in PERGOLUX Products

When it rains - and it does, a lot - your outdoor space shouldn't suffer for it. At PERGOLUX, we've engineered our products so that rainfall simply disappears: invisibly, quietly, and without a downpipe in sight. We’ve produced RainLUX, our integrated drainage system that works so well, you'll barely know it's there.

What Is the RainLUX System?

RainLUX is the hidden drainage architecture built into every PERGOLUX product. Rather than relying on external guttering or exposed pipework, it channels water from roof to ground entirely within the structure itself. Think of it like the plumbing inside your walls - essential, cleverly concealed, and completely out of view.

The journey water takes is elegantly simple:

- Rain lands on the roof 

- A built-in slope guides water towards the perimeter beam gutters

- The beams - which double as integrated gutter channels - collect and contain the flow

- Water routes down through the hollow structural posts

- It exits discreetly at the base, through weep points in the footplates

No external downpipes. No bolt-on guttering. Just clean lines and reliable performance.

How It Works Across Our Range

The RainLUX principle runs consistently through the Series 3 family, but each product brings its own engineering refinements.

Pergola S3

The foundation of the range. Single-walled aluminium louvres with a built-in slope channel water directly into the perimeter beam gutters, which then route it down through hollow posts. Structural support and drainage column, all in one.

Sundream S3 

Our premium motorised pergola takes things a step further. Double-walled louvres with internal gaskets create a tighter seal when closed, managing water more precisely. Thicker beams are explicitly integrated with the gutter channel for enhanced leak prevention, while gutter brushes handle debris and drip guards prevent water creep at beam edges. Same system, meaningfully refined.

Skydance S3 

Built for larger spans. Wider double-walled louvres increase the roof's surface catchment, while substantial posts provide greater internal drainage volume. On the 4×6m configuration - which has no centre post - water routes efficiently through the outer posts only. A clean engineering solution for an ambitious structure.

Conservatory 

Our Conservatory swaps louvres for a fixed glass roof with a 5° slope, guiding rainfall smartly towards the front beam gutter. From there, the RainLUX system channels water through both front posts to the base. Same hidden principle, adapted seamlessly for glass.

Why It Matters

Great drainage isn't just about keeping you dry, it's about protecting your investment and preserving the aesthetic integrity that makes a PERGOLUX structure so distinctive. External gutters collect debris, demand cleaning, and introduce visual clutter that undermines the clean lines you've chosen. RainLUX eliminates all of that.

It also means no unsightly downpipes running along your posts, no awkward planning around external drainage routes, and no maintenance headaches. Every element earns its place - structure and water management working together, invisibly.

For a product designed to become a genuine extension of your home, this kind of engineering should be exactly what it is: effective, discreet, and built to endure.

Frequently Asked Questions

Does the RainLUX system require maintenance? 

It's designed to be maintenance-free. On Sundream S3 models, gutter brushes help manage debris within the channel. An occasional check after heavy leaf fall is all that's typically needed.

What happens if the louvres are open during rain?

When the louvres are open, rain passes through the structure rather than onto the roof. RainLUX is designed to work when the louvres are closed, efficiently directing water through the integrated drainage path.

Does drainage affect the Snap-Fit accessory tracks? 

Not at all. The Snap-Fit tracks for accessories such as lighting, screens, and heaters are integrated into the gutter beams alongside the drainage channels - both functions working in harmony.

Is the drainage system the same for the Conservatory? 

The principle is identical, but because the Conservatory has a fixed glass roof rather than louvres, the drainage path begins with the 5° glass slope before feeding into the RainLUX system through the front posts.
