Draught Proof Your Shugg / Frameless / Sashless Windows (GCE6)
If your windows look sleek and “architectural”… but your living room feels like it’s getting fresh-air delivery on subscription, you’re not imagining things.
Shugg / frameless / sashless windows have a deliberate gap where two panes overlap and slide past each other. It’s great for the minimalist look. It’s also a fabulous little entry point for cold drafts, hot gusts, noise, dust, bushfire smoke and pollen.
The tricky bit? These windows don’t give you much frame to work with, and generic foam tapes tend to be too bulky, too sticky, or just end up looking like a DIY crime scene.
So we have a discrete brush seal that suits your window.
How do we stop the draughts (without ruining the “frameless” look)?
Meet the GCE6 Draught Excluder – purpose-designed for Shugg / frameless / sashless windows.
It’s a clear clip-on edge strip with an integrated brush that sits neatly where the air leaks happen: between the overlapping glass panes. It’s low-profile, it doesn’t interfere with the sliding action, and once installed, it’s barely noticeable… until you realise the breeze has disappeared.
What is the frameless window draught seal?
The GCE6 is a draught seal made specifically for 6mm thick glass on Shugg/frameless windows, designed to reduce air leakage while keeping the window operating smoothly.

What problem does it solve?
It seals the “air highway” between panes so you can:
- feel less cold air in winter and less hot air creep in during summer
- reduce outside noise
- cut down dust, pollen, insects and smoke sneaking in
What’s in the kit?
A single GCE6 strip (clear holder with a black brush), ready to cut to length and fit.
Options: available in multiple lengths (choose the one that suits your pane width).
Note that the the ‘6’ in GCE6 indicates that this product is for 6mm wide glass ONLY.
No, sorry, we do not stock 8mm or 10mm options.
How to install it (DIY-friendly)
This is easy peasy. The GCE6 is designed to be measured, cut, and clipped on — no special trades, no complicated tools, no multi-video instructions.
Basic steps:
- Measure the edge you want sealed
- Cut the GCE6 to length
- Clip it onto the glass edge so the brush seals the gap as the panes overlap
There’s also an installation video available if you prefer to watch the “how-to” first.
Why the GCE6 works (when other fixes don’t)
Because it’s made for the job.
Shugg/frameless windows are “hard-to-treat” because there’s no frame and the leak is between glass panes, not around a conventional sash. The GCE6 is built to sit directly on top of the lower pane and provide a weatherproof seal without damaging the glass or preventing the sliding action.
It’s:
- clear and discreet once fitted
- easy to install (measure, cut, clip)
- designed to suit typical gaps in these windows (fits 6mm glass and covers approx 7–10mm gaps)

A high-quality plastic holder with a brush (nylon).
Expert tips
If your home still feels “leaky” after doing the obvious windows, it’s usually because there are multiple leak points around the house (doors, vents, fan penetrations, etc.). If you want a guided approach, our Find and Fix My Draughts program helps you track them down methodically.
