Leading aluminium entrance doors for any home

Contemporary, square-edge aluminium profiles that come in either single or double residential door varieties allow for the creation of stylish facades that are low maintenance, robust and built to last. Aluminium residential doors are becoming increasingly popular with homeowners, and the Alitherm Plus system is one of the leading aluminium entrance door solutions available today.

Able to be built with individual door sash sashes that are up to 1000mm x 2500mm in size, they are also available with a Document M compliant low threshold, for properties requiring ease of access.

    Ultra-secure & energy-efficient residential doors

    Thanks to extended polyamide thermal breaks, they easily meet the standards of Document L. This ensues they provide a solid thermal performance to any area they’re fitted, keeping premises warm and cosy.

    However, they also come equipped with high-quality multipoint locks and strengthened hinges as standard, making them an ideal option to secure any domestic premises. As they’re accredited to BS6375:2009 parts 1 and 2 as well, wherever they’re fitted they guarantee a weather-tight fit.
