Calibre Doors was launched in early 2019 when Aperture Trading Limited bought the assets of a Nether Heage-based door business that had entered administration, not only ensuring continuity of supply to the market but also saving over 150 jobs.

Since then, Calibre Doors has quickly established itself as the first-choice partner for UK-based housing associations, councils and new build developers looking to provide secure yet stylish entrance door solutions.

Calibre’s range of timber and GRP composite doors are two of the most highly specified entrance doors in the UK, and have been engineered to offer a wide choice of colours and style without compromising on quality, security and longevity.

Calibre also continue to offer the Warden range of fire doors, the first timber fire doors in the UK to be comprehensively furnace tested on both sides and sold with a valid 2018 test report for peace of mind.
