New data reveals misconceptions over timber windows and doors 

A new survey of 1,500 UK homeowners has revealed signs that timber windows and doors are viewed positively by homeowners, but that there are misunderstandings over how they perform, their overall cost and how they are maintained. 

The survey conducted by the British Woodworking Federation (BWF) revealed that 59% of homeowners felt that timber windows offered a wider opportunity for design and style options than alternatives, and 56% thought timber windows were more sustainable.   

Despite these positive perceptions, research also revealed a number of misconceptions over timber windows as compared to alternatives. 

Fewer than half (40%) believed timber windows offer high energy efficiency performance, and more than half (57%) thought they cost more than alternatives to purchase and install. Almost two thirds (70%) believed timber windows have a shorter lifespan and will need more frequent replacement than alternatives.  

Commenting on the findings, Helen Hewitt, Chief Executive of the BWF, said: “With the cost of living and energy crisis ongoing, it comes as no surprise that cost and energy efficiency are the primary concerns for homeowners when selecting windows for their property. But there are still some outdated assumptions over timber windows’ energy efficiency performance. It’s really important that homeowners have the full range of information available to them to help them make informed choices.” 

Kevin Underwood, Technical Director at the BWF, discusses the major myths over timber products and shares his view on why wood windows and doors offer great performance and value: 

Myth 1: Timber windows are expensive

The improved durability of wood window frames means that they can last longer and therefore actually work out less expensive over their lifetime compared to alternatives. Not only can wood window frames have a long service life - often longer than other common window materials - but they can also provide lower whole life costs when maintenance and replacement are factored in.  

Myth 2: Timber windows are less energy efficient 

Timber is a naturally insulating material, and timber windows can offer better thermal performance than alternatives. However, the energy efficiency of a window is about much more than just the frame; the glazing and draught-proofing have a major impact on performance. 

Myth 3: Timber windows will rot quickly and need replacing 

When correctly maintained, wood window frames can last up to 60 years, with certain types of modified wood even boasting a lifespan of 80 years. This is due to major technological advances in the design of wood window frames and their manufacturing processes over the past two decades. Engineered or modified timber, which is primarily used by BWF members in the manufacture of wood window frames, is vital to longevity.
