Opting for the Benefits of Timber Windows and Doors
Timber windows and doors have always scored highly on the style front and from an aesthetic and human interaction perspective they absolutely win hands down over other materials.
But the development of new manufacturing technologies means performance and longevity makes timber a great choice.
Matt Chambers, National Sales Manager at Dale, highlights the advantages of opting for wood.
- Are timber products high maintenance?
At Dale, all our products are made to measure to meet the customers’ specific needs. As a result, they are delivered to site fully finished and ready to fit. This is a major advantage for the builder and their customer because nothing needs doing.
No glazing, painting or finishing required.
The beauty of our low maintenance timber doors and windows is in the factory applied paints. The paints and stains are guaranteed for 8 and 5 years respectively. All that is required is an occasional clean and inspection to ensure the paint is in top condition.
In recent studies researchers have found that when properly protected with paint or woodstain, timber windows last twice as long as PVCu
- What type of timber is used?
At Dale we only use sustainable European Redwood timber as standard in all our windows and doors.
he use of European Redwood fulfills several requirements, it is easily grown and grows with few knots, the wood itself is naturally water resistant and the tree grows beautifully straight.
- Does timber warp?
If you opt for cheap, mass produced off the shelf products then there is a high likelihood that you will encounter warping or sticking.
The weak point of wood is the way that it can absorb moisture. As it does the wood swells and twists in the direction of the grain of the wood. It is this movement that results in the detrimental warping.
At Dale we use Multi-layered, ‘engineered’ timber. By layering wood with the grain of its neighbour lying in the opposite direction, the wood’s natural properties are increased, the knot free multi-layering creates a fantastically strong material. This means warp and twist free timber, and extremely strong windows and doors that are impervious to the movement that causes sticking and jamming.
- How important is the property location when specifying timber windows?
Location is an important factor. Where a property is in an exposed location, opt for Stormproof windows or ‘lipped casements’ which are designed for harsher environments.
The edge of the window is wider than the opening so when drawn closed it forms a protective lip over the frame to protect against extreme weather conditions
For windows in exposed locations make sure you opt for products that meet recognized standards. Our Stormproof windows have been independently tested and approved in accordance with BS 6375-1:2009 and BS 6375-2:2009
Part 1 – Weathertightness
Part 2 – Operation & Strength
Has exceeded requirements for:
Air Permeability (EN1026)
Resistance to Wind (EN12211)
Operating Forces (En 12046)
Static Torsion (EN 14609) Racking (EN 14608)
Soft Body Impact (EN 13049) Safety (EN 14609)
Repeated Opening (EN 1191)
- How Important are U values?
Around 66% of the energy lost from a standard window is through the radiation travelling through the glazing, known as the U-value. The lower the U-Value, the less heat loss and the more insulation is provided.
Consider as standard double glazed units featuring performance glass along with warm edge spacer bars and argon gas for superb insulation. Look for U Values of at least 1.1 W/m2K (centre pane u-value) which equates to 45% more energy saved than with ordinary double glazing, and 80% more than single glazing.
- Do timber windows and doors come with warranties and guarantees?
It depends who you get to manufacture your windows and doors as to what guarantees you will get. At Dale our products come with a range of minimum standard guarantees.
- 30 Years – Rot & fungal infection
- 10 Years – Double glazed units
- 10 Years – Hardware
- 8 Years – Paint finishes
- 5 Years – Stain finishes
It is essential that you know how your windows and doors are manufactured, coated and painted or you could be creating problems for yourself and your customers in the future
If you are having your windows and doors manufactured by a local joiner, ask them what they do to prevent the prospect of twisting or warping once the products are fitted and exposed to a harsh winter and ensure they have paint or stain finish guarantees if they offer to finish them.

Selecting the right windows and doors for your project is vitally important on an aesthetic, performance and longevity level.
