Exitex Macclex MXS 15/2 Aluminium Door Low Threshold Cill 914mm Thermally Broken

Exitex Macclex MXS 15/2 RITB Thermally Broken Aluminium Door Threshold

Thermally broken aluminium door threshold for inward-opening doors up to 44mm thick – cuts draughts and helps stop condensation on the inside edge.

Exitex Macclex MXS 15/2 RITB is a thermally broken aluminium door threshold for inward-opening doors up to 44mm thick, and a straightforward fix if your existing threshold is letting in cold air, gathering condensation or simply past its best. A standard aluminium threshold conducts cold straight through to the inside of your home; this RITB version breaks that path, so the doorway stays warmer and drier without the cost of a new door.

As a genuine Exitex product, it is manufactured from hard-wearing aluminium built to stand up to daily foot traffic for years. Its low-profile, Part M compliant design makes it a practical choice for both new fittings and like-for-like upgrades.

Key Benefits for Door Threshold Replacement:

• Warmer Doorway, Lower Heating Bills – The thermal break separates the internal and external aluminium sections, so far less cold passes through the threshold into your home. Keeping the internal edge warmer also reduces the risk of condensation and water collecting on the inside.
• Stops Draughts at the Base of the Door – Helps seal the gap at the foot of the door against draughts and weather, making the room noticeably more comfortable through the colder months.
• Smooth, Snag-Free Door Operation – The slim 15mm profile keeps your door opening and closing freely, rather than sticking or dragging across the threshold.
• Easy Access for Everyone – Part M compliant and suitable for wheelchair access, so the doorway stays safe and practical for all the household and visitors.
• Built to Last – Hard-wearing aluminium construction means you avoid the frustration and repeat cost of cheaper thresholds that wear out quickly.
• Precise Fit for DIY Installers – Cut it down on site to the exact width of your single door opening for a neat, professional-looking finish.
• Saves the Cost of a New Door – Replacing a worn threshold restores comfort and appearance at a fraction of the price of full door replacement.

Standard MXS 15/2 vs Thermally Broken MXS 15/2 RITB

Already have the standard MXS 15/2?
Choose the RITB version if you want to keep the same style of low-profile threshold while upgrading to a thermally broken design, subject to checking the installation dimensions above.

Before You Order:

Many aluminium thresholds look alike, so compare the profile shape and underside arrangement of your existing threshold with this RITB version rather than going by appearance alone. If you are unsure which size you need, please contact us and we'll be happy to help.

Pro Tips:

Pro Tip: Offer the threshold up dry to the opening before cutting and mark your cut line against the door frame. A threshold can't be extended once it's cut, so check the fit twice before making the final cut.

Frequently Asked Questions:

Will this threshold work on an outward-opening door?
No – the MXS 15/2 RITB is designed for inward-opening doors only, up to 44mm thick.

What does "thermally broken" mean on a door threshold?
It means an insulating break separates the inside and outside aluminium sections, so cold isn't conducted straight through to the internal edge.

Can I cut this threshold to fit my door, and will it work on double doors?
Yes, it's supplied at 914mm and can be cut down on site to suit your opening. It is designed for single door openings only, not double or French doors.

Is this aluminium threshold suitable for wheelchair access?
Yes – it's Part M compliant, with a low-profile design suitable where wheelchair access is required.
