Most of the oldest buildings in the country, those that we have all admired and enjoyed – from castles and palaces, to places of learning, prayer, contemplation and recovery – have magnificent doors made from timber. Today these national treasures, protected and cosseted with the help of private trusts, public ownership and a stream of funding to support regular maintenance, look every bit as imposing as they did when they were crafted.

This cannot be said of the cheap imports, mainly from the Far East, that were much needed to support the explosion of property ownership in the 1960s through to recent times. For those who did, and can still, purchase their local authority house at a fine discount, ownership encouraged investment in new doors and windows. The market research carried out by the British woodworking industry in the late 1970s, when Taiwanese imports were at their highest level, identified that UK home owners typically paid an average of £50 for a new front door, a stark difference to their West German counterparts who would pay in the region of £3000.

“This prompted an industry-funded campaign aimed at the private home owner to invest in a new timber entrance door, made in the UK, named: What a Difference a Door Makes,” says Roy Wakeman, CEO, The Performance Timber Products Group. “The campaign was hugely successful and while it didn’t see off all the cheap imports the consumer became educated about the benefits of a home-produced timber door and willing to spend more. By the mid ‘80s the market peaked at 3m units and had a value of £400m.”

Inevitably the bubble burst, brought about by the plastic revolution and campaigns selling the virtues of double glazed fenestration with low pricing and so called ‘authentic, classic design’. By 2000 the timber market share was lost in windows alone, by some 80%, in favour of plastic. Timber doors however retained a higher share as the consumer was attracted to the greater security of timber and its performance.

More recently the industry has seen the rise of composite door constructions where modern materials have been used to make up the door core; this has then been covered with an external finish of thermal plastic; glass-reinforced plastic, GRP; and even wood fibre-based boards. These products have performed and today account for more than half of the UK market, now measured at £600m with growth of more than 5% per annum.

Security and robustness has been achieved by the strength of the door core together with good ironmongery. Today this will contain espagnolette systems that can lock all three leading edges using shoot bolts, or hooks, with a central controlling arm handle.

A national standard for security has existed, along with test methodology to BS7950, which values security, thermal performance and weather resistance to regional degrees of exposure. A police-recommended standard and marketing tool for the private housebuilding sector, Secured by Design, has prevailed for more than 30 years and is frequently a standard requested by designers, architects and developers responsible for new developments.

Only last year the new Approved Document Q Building Regulations was introduced for the new-build sector which demands even greater security standards for doors and windows. The security standard demanded by Building Regulations, to which products are tested, is known as PAS24 but prior to this all products must be tested and rated for weather and air tightness to meet BS6375 (Parts 1 & 2).

“While the requirement to meet Doc Q applies to new buildings only, existing home owners will want these security benefits applied to replacement products for the upkeep and maintenance of their properties as well as for major refurbishments and extensions,” says Roy Wakeman. “Current research suggests that the major driving force for home owners when purchasing new doors and windows is security and energy conservation.

“It comes as no surprise that the timber door, complete with all the appropriate ironmongery, factory assembled and finished, is now leading the way again to dominate the choice for new door designs and mechanics that more than satisfy today’s demanding standards.” Products manufactured by Mumford & Wood entirely in Great Britain all meet the very highest standards demanded today.

Timber is the most versatile of all materials and can be easily finished with modern water-based paints or stains, chosen from a huge range of colours and shades. These modern finishes now come with life time warranties for the complete door set, with maintenance cycles at a very minimum, and the paint itself is expected to last up to eight years before re-decoration is needed.

Composite door cores, using urea or phenolic forms, are not exactly the best products to satisfy today’s demanding consumer who knows all about active carcinogens and the toxicity of chemically-based products. For complete peace of mind it is far better to use a sustainable and naturally-replacing material, such as timber, to ensure that our children’s children grow up in a safe, sound and comfortable environment behind modern timber windows and doors.

Modern timber engineering techniques and water-based, friendly finishing treatments, do make timber the material with the very greenest credentials.

High performance timber windows and doors from the Mumford & Wood Conservation™ range have been specified in an historical property refurbishment in the beautiful village of Clifton, Bristol. In Tudor-Gothic style this stunning collection of seven luxury-living properties offers outstanding accommodation enhanced with space and light.

The sympathetically converted Grade II listed school building has been revived by Kersfield Developments, Bath, together with contractor Construction Total Solutions, Bath, to form a walled boutique development that encloses five houses and two mews properties. The building is recognised locally for its iconic diaper patterned roof.

Double glazed casement windows from the coordinated Conservation™ range have been specified by architects Nash Partnership, also of Bath, and designed to work in harmony with the traditional stone surrounds and other architectural features typical of the region. Solid planked entrance doors with decorative overhead fanlights provide like-for-like replacement and Conservation™ bi-folding doors are featured in several of the properties adding yet more drama to the internal space. These doors have an open-out configuration and are available up to 5.9m wide and 3m high to achieve maximum impact. Both entrance and bi-folding doors are Secured by Design accredited within the Conservation Secure™ collection and meet Approved Document Q – Security of Building Regulations, which applies to the new build housing sector.

The architectural preservation of this much-loved building has been sensitively considered throughout the design process. Purpose built in 1850 the original Church of England School building was saved from demolition in the 1960s and remained in use as a school until 1979 in response to public outcry. Bristol City Council became the new owner using it as a district office with much of the original architecture hidden from view. In stripping back the building to its original timber trusses and classrooms, the building’s classic origins of spacious dimensions have been recreated.

“This building has had new life breathed into it,” says Frank Buckley, managing director, Mumford & Wood Limited, “and we are proud that our award-winning windows and doors have helped to recreate its historic charm. Our products have worked beautifully with the sweeping, open spaces of the building which offers generous open plan living so popular in today’s family living style.”

Double glazed Conservation™ windows and doors are made to the exacting standards of the British Woodworking Federation’s Wood Window Alliance (WWA) scheme and are BRE A+ rated offering outstanding levels of thermal and acoustic performance. They are manufactured from premium grade Siberian Larch which is engineered for maximum strength and stability to help ensure long lasting aesthetics and performance, while achieving a perfect factory-finished, paint-ready surface typical of fine joinery. Independent research carried out by the WWA on behalf of its members identifies that timber as a frame material offers the most sustainable and cost effective material with a life cycle of up to 65 years and more.
