Masterdor is a pre-finished door-set

Masterdor is a pre-finished door-set, complete with hardware and glazing. The door is supplied as a ready to install unit. Independent tests have shown it to provide the solution to the problems encountered by most residential doors. It forms an effective barrier to weather and intruders, is easy to maintain and repair, and is made to measure in a wide range of styles and colours. Masterdor Ltd is capable of producing 50,000 doors per annum. Virtually all of the Masterdors in current use are in local authority and housing association stock.

Masterdor is the brand name for a range of high-performance door systems

These are manufactured in many different styles, to any size and in a very wide colour choice. The ‘Thermal’ ranges have an
insulating core and are finished in either Permaskin (an ASA thermoplastic film) or microporous paint. They have exceptionally low U-values and exceptional air-tightness (800 Special) whilst also meeting and exceeding the requirements of PAS 24 and Secure by Design.

Energy efficiency

Energy saving doors from Masterdor help you save on heating bills by keeping the heat in. They also protect the environment as all timber used in the manufacture of our Masterdor range comes from sustainable, managed stocks. As a business Masterdor has achieved ISO14001:2004 for environmental compliance.

Trained door installers

We adhere to stringent quality standards and compliance to ISO9001:2008 in a factory where consistency of finish and performance is assured, and our products are never compromised due to badly fitted hardware, locks or glazing.

In addition, the Approved Installer Scheme, introduced in 1997, ensures that our door-sets are always stored, handled and installed by trained people operating under an approved scheme. As part of the guarantee system, Masterdor Ltd. operates a post-instalment inspection on a sample of doors.
