ENVIRONMENTAL SUSTAINABILITY AND TIMBER WINDOWS

Timber is the most sustainable of materials from which to manufacture windows and doors.

Timber from responsibly managed forests

We can supply our joinery in hardwoods such as Sapele, Idigbo, Oak and Grandis but the majority of our products are made from FSC certified engineered Redwood (pine), which comes from forests in northern Sweden. As trees are felled, two or more new saplings are planted to replace them. In effect timber is a slow-growing crop and because of its versatility, there is a greater area of forest in Europe now than at the start of the 20th century.

Our most frequently used hardwood is Grandis which is plantation-grown in the southern hemisphere so carries the full FSC certification signifying truly sustainable cultivation and harvesting of the timber.

As a tree grows it absorbs CO2 from the atmosphere via a process called photosynthesis. There is a by-product - oxygen. For every cubic metre of timber grown, one tonne of CO2 is sequestrated from the air. Timber is therefore a 'carbon sink'.

The processing of lumber into timber batons and then into finished products such as windows and doors also utilises waste wood (sawdust and shavings) as a source of energy providing a low-cost and environmentally friendly alternative to fossil-fuelled energy.

It has been calculated that even after all the processing from the forest to finished product, timber windows and doors are net 'carbon negative'. That is, there is more carbon bound up in the timber than has been put into the atmosphere in the manufacturing process. No other material can come close to this claim.

The environmental story is further enhanced when you consider the durability of timber as a material. Properly maintained timber products will last for decades. Because timber can easily be repaired if it is damaged and can be made to look new again with a new coat of paint, there is less need to replace timber windows. They are versatile too - the addition of a different coloured paint can transform the appearance to suit new furnishings.

The design of a good timber window should consider how to minimise contact between the timber and water. It is impossible to stop windows getting wet but modern designs protect the most vulnerable areas with drainage and ventilation. Combined with 21st century preservatives and water-based micro-porous paints, today's good quality timber windows have never been so well protected. Little wonder then that Blackthorn Timber Windows have a life expectancy in excess of 30 years.

But beware! Not all timber windows are the same. Please refer to "10 reasons to choose Blackthorn Timber Windows" when comparing our products with any others and we're confident you'll find significant differences.
