Why Buy Timber Doors & Windows For Your Property
Why Choose Timber Doors and Windows For Your House
Property owners in the uk like timber windows and timber doors, yet many have switched to PVC. Why? Well, according to many sales representatives, PVC doesn’t rot like wood, it’s less expensive and naturally it does not need painting. Sounds great but before you rush off to place your order, in this, my first blog post; I am going to challenge that wisdom.
I could be a Norwegian living in Great Britain. In Norway we have lots of wood and very cold winters. Therefore over a period we’ve become pretty adept at using our abundant resources to keep us warm; but more importantly as an effectual building material.
All though Norway only a few properties feature PVC windows. This is down to the fact that wood, by its make up is a natural barrier to the cold. When smartly designed and designed into a window or doorway, and together with double or treble glazing, it far outperforms PVC doors & windows. So why is PVC so favored in England? The reasoning is varied to many many the experience of rotten timber windows is related to those installed in properties after the 2nd World War. Have you considered how many properties built over a century back still have their original windows? This is due to the fact that they were made using well seasoned, prime quality timber. By stark contrast, many buildings built during the post war period were constructed using inferior materials. Hence timber gained itself a poor reputation.
So what’s the present day truth?
Currently around 12 million windows of all sorts are sold annually in Great Britain, with timber windows accounting for 30 percent of that market. 57% of timber windows sold in Britain are utilised by the public sector and 42% by the non-public; 86% of these in rebuilding projects and 14% for new build applications. (Figures from FSC internet site.)
While Norwegian doors and windows have always used top quality materials, during the last 10 years in particular, the evolution of timber windows in terms of quality, durability and design has been dramatic. Factory finished and treated against rot, with frames which are fully defended from water and UV light; modern high-performance timber windows can have finish guarantees for at least ten years, and rot free guarantees for as much as thirty. Dual sealing and factory glazing helps to maximize the life of a unit, and complex design elements further lengthen the life of the timber.
Comparing this to PVC units, The National Building Federation’s Standards in Quality and Development gives PVC windows a lifespan of twenty to twenty-five years; where as it gives vacuum treated softwood windows twenty-five to 35 years. According to the Green Builders Digest, ‘Well designed and well looked after timber windows can and do last the lifetime of the building in which they are installed’.
Up keep is the challenge for many people, but no material is maintenance-free, in spite of claims by PVC salespeople. Developments in timber window design and finish has developed products that reduce water retention, damp penetration, and with micro-porous paints that allows wood to breathe; all make a contribution to a low up keep product. Peeling and blistering paint is a thing of the past. Factory-finished windows do not need to be repainted for as much as Eight years. And so Five to Eight year painting cycles is the standard. Modern finishes also decrease the preparation times. Unlike PVC, your factory finished timber doors & windows can be made to an actual shade of Colour to compliment project and property. Hence even though it remains correct that timber windows do require some up keep, modern high performance windows make that up keep exceptionally easy.
While the initial value of timber windows can be higher than that of other materials, the ‘whole-life ‘ cost which timber delivers in terms of maintenance, sturdiness and environmental impact, makes it excellent value for money.
To substantiate the excellent value claim The National Housing Federation finds softwood much cheaper, both in terms of initial capital costs and life cycle costs over a period of Thirty years. Figures from its reports, ‘Standards in Quality and Development ‘, put the costing of buying, fitting and maintaining a softwood window frame at between £149 and £199 over Thirty years. By contrast a PVC frame will cost between £257 and £275.
Another cost advantage to wood windows is the facility to fix and revive them. According to TRADA, the Timber Research and Development Association, wood can be immediately mended,. Refreshed and maintained without special parts, abilities or gear.
Eventually, timber is, of course, a natural insulator which when mixed with the glazing system, (air, argon or krypton filled), insulating glass and draught sealing, has no problem in providing windows which meet current requirements of a U-value as low as 0.6W/m2K.
To conclude
Obtained from managed forests, usually from my homeland of Scandinavia; timber is an environmentally friendly, thermally efficient, good looking and low upkeep material. All of which is, happily, a long way from the poor reputation created by cheap, bad quality softwood windows and doors of the recent past.
For me, all of the above makes very good sense, and when it comes to timber doors & windows nothing looks & feels as good as wood.
