Our promise
Windows carrying the Wood Window Alliance brandmark are independently audited to meet the following quality and performance standards:
The most sustainable
The lowest carbon
Unbeatable for energy-efficiency
Unbeatable for responsible sourcing
Unbeatable for service life
Unbeatable for the range of styles and finishes
Unbeatable for value
Unbeatable for warranties
The most sustainable
- Sustainably sourced wood is the most environmentally-friendly construction material
- WWA windows rate ‘A+’ in the BRE’s Green Guide (based on domestic windows manufactured to TWA Scheme standards)
The lowest carbon
- WWA windows rate ‘A’ on the Climate Change Indicator in the BRE’s Green Guide
- Research by Davis Langdon shows WWA windows are ‘carbon negative’
Unbeatable for energy-efficiency
- A window’s energy-efficiency is governed by its glazing
- WWA windows have the same double or triple glazing options as any other type of window
- The strength of the wooden frame makes triple glazing easier
- While the low thermal conductivity of wood helps minimize ‘cold-bridging’
Unbeatable for responsible sourcing
- All members have Chain of Custody accreditation for their use of sustainably sourced timber. No other material has such stringent standards
Unbeatable for service life
- The BRE gives our windows a minimum 35 year service life
- But we expect our windows to last a lifetime, so long as they are maintained properly
Unbeatable for the range of styles and finishes
- From elegant conservation windows to the latest aluminium clad styles
- Factory finishes are available in a wide range of colours and stains
Unbeatable for value
- Surprisingly, high performance wood windows cost very little more than their PVC-U alternatives
- And, because they can be maintained, and last longer, they are actually less expensive over their whole life
Unbeatable for warranties
- Typically our members offer a 30 year warranty on the frame
- 8 years on the paint finish
- 10 years on the glazing, seals and ironmongery
