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 threshold that helps prevent condensation and reduce draughts on inward-opening timber doors.

Exitex Macclex MXS 15/2 RITB is a straightforward upgrade if your existing threshold is letting in cold air, causing condensation, or simply past its best. Unlike a standard aluminium threshold, which conducts cold straight through to the inside of your home, this RITB version incorporates a thermal break to reduce heat loss and help prevent condensation forming on the internal edge. Designed for inward-opening 44mm timber doors, it's a low-profile 15mm threshold supplied at 914mm long for single door openings, and it provides genuine Part M wheelchair-accessible clearance. For anyone replacing a worn or damaged standard MXS 15/2 (Exitex reference 1.01.0317), this is the natural next step up.

As a genuine Exitex product (reference 1.01.0760), this threshold is manufactured from hard-wearing aluminium designed to withstand daily use for years. It can be cut down to the exact length required during installation, and its low-profile design and 13mm under-door clearance make it a practical, compliant option for both new fittings and like-for-like upgrades.

Key Benefits for 44mm Timber Door Owners:

• Thermally Broken Construction – Separates the internal and external aluminium sections to reduce thermal bridging, so less cold transfers through the threshold and into your home, helping to keep heating bills down.
• Helps Prevent Condensation – By keeping the internal edge warmer, the thermal break reduces the risk of condensation and water collecting on the inside of the threshold.
• Cost-Effective Upgrade from the Standard MXS 15/2 – Gives you the benefit of a thermally broken threshold without the expense of a full door replacement, ideal when your existing threshold is worn or damaged.
• Draught and Weather Protection – Helps guard against draughts and weather ingress at the base of the door, improving comfort and reducing heat loss.
• Low-Profile 15mm Design – A slim 62mm-wide, 15mm-high profile with 13mm under-door clearance that keeps doors operating smoothly, rather than sticking or dragging.
• Part M Compliant, Easy-Access Design – Suitable for wheelchair access, making it a practical choice where accessibility matters.
• Hard-Wearing Aluminium Construction – Built to last, so you avoid the frustration and expense of cheaper parts that fail quickly.
• Supplied at 914mm Long – Sized for single door openings and can be cut down further on site for a precise fit to your door width.
• Cut-to-Length Installation – Can be cut down to the exact size required on site, giving DIY installers a precise, satisfying fit.

Pro Tips:

Pro Tip: Before cutting the threshold to length, offer it up dry to the opening first and mark your cut line carefully. Thresholds can't be extended once cut, so it pays to measure twice and check the fit against the door frame before making the final cut.
