At Timbertherm, we’re members of the Forest Stewardship Council meaning that we promote the sustainable and sympathetic use of timber windows and doors when working in conservation areas and listed buildings, in fact for all of our timber windows and doors we only use timber that is conservation-approved.

Timber windows and doors have been used throughout the United Kingdom for centuries, often being the natural choice due to their beauty, warmth and durability. However, with there being alternatives to timber, mainly the use of PVC windows and doors, this poses a great threat to property values in conservation areas. In fact, English Heritage said that unsympathetic windows and doors (particularly PVC-u) were the single biggest threat to property values in conservation areas and the Royal Institute of Chartered Surveyors stated the ‘inappropriate replacement of windows and doors’ as a top crime against period homes. 

With over 30 years’ combined experience in creating and installing timber windows and doors, we offer the sympathetic replacement of timber windows and doors in conservation areas and listed buildings. If your original windows and doors are beyond repair or have been replaced by a lesser-quality PVC counterpart, we’ll create and install an exact replacement of your original design, preventing your property value from decreasing and keeping with the aesthetic of your period building.

With our wide range of windows and doors to choose from, including multiple designs available within each section, we can replicate authentic window styles and even replicate an ‘older’ look that won’t be distinguishable from your original ones.  

Using the best materials and first-rate techniques, we can also improve your property’s windows by adding specialist glazing that decreases its energy u-value, making it more thermally efficient. 

With modern techniques, we can also upgrade the security in your original windows and doors, using concealed security features and multi-point locks.
