Profile & Features
Click & Forget Clip In Beads
Clip-in beads are also fully available on our Aluna range of bifold systems. Our clip in bead is unique in that when installed with our market leading Aluna profile, installers benefit from both flexibility and ease of installation, dramatically reducing the time of install per pane.
What sets our new bead design apart is the confidence in the sound it makes as it is installed. Simply click it into place without the need for tools or any excessive force where traditionally, glazing would require a time-consuming wedge gasket.
Unique Universal Lock Keep
Our PAS24 (2022) accredited Lever Lever Lock System enables the ultimate symmetrical, premium, sleek finish to your fabricated door. It’s unique locking option can be installed within our super slim sash creating an aesthetically pleasing finish to the door design.
Gone are the lever and opposing slave door handle and in there place is a uniform mirrored aesthetic with dual handles. To upgrade to Lever Lever no additional gaskets or profiles are required.
Rebate End Cap
Speed, ease, confidence, revenue. Supplied as a pair an easy to snap sprue with a new foam gasket the Aluna rebate end cap improves sealing against the sash
With easy installation – 1 turn of the grub screw locks the end cap securely into place. No messy gluing process is required and the end cap remains firmly in place during transit to site.
Glazing Packer
Making glazing even faster for installers, offering the optional Aluna glass packer differentiates fabrication. Simply fit into the corners of the sash for enhanced speedy toe and heeling, this 4mm thick recycled plastic addition makes installs fast and easy.

Standard Threshold
The standard threshold (55mm) acts as a full weather break, keeping the property dry and warm regardless of outside elements. Recommended for external bifolding doors.
Integrated Cill & Threshold
Our integrated cill and threshold profile provides full weather rating on our lowest threshold and maximises the overall sash height of the door leaf. For ease of fabrication, the profile already has pre-drilled drainage slots along the inside face.
Low Threshold
Our Low Threshold (20mm) doesn’t offer as much weather protection but creates a seamless look. Lower thresholds are less of a trip hazard than higher ones so are more suited for those with mobility issues or small children.
Low Threshold with Ramps
When a threshold can’t be sunk below floor level and accessibility is required, a ramp can be added either side of the low threshold as an optional extra.
Universal Aluminium Cills
Alunet’s range of universal aluminium cills with pre-drilled screw ports are compatible with most other door and window systems, as well as with our ALUNA bifold system. Their main benefits are directing water away from brickwork while also offering an additional design element to the aesthetics of the door or window.
