Frequently Asked Questions
What are the benefits of specifying timber windows for construction projects?
Timber windows offer excellent thermal performance, design flexibility and sustainability credentials. For contractors, modern timber windows can help meet project performance requirements while delivering the premium appearance often sought in residential, education, hospitality and heritage schemes.
Why are timber windows a sustainable choice for commercial developments?
Timber is a renewable material that stores carbon throughout its lifecycle. When sourced from responsibly managed forests, timber windows can help support project sustainability goals and reduce embodied carbon compared with some alternative materials.

Can commercial timber windows meet Building Regulations?
Yes. High-performance commercial timber windows can be designed to meet current thermal, weather performance, acoustic and security requirements. Product performance will depend on the specific window system and glazing specification selected.
Are timber windows suitable for heritage and conservation projects?
Timber windows are often the preferred solution for listed buildings, conservation areas and heritage restorations. Bespoke manufacturing allows traditional sightlines and detailing to be replicated while incorporating modern performance benefits.
What should contractors consider when specifying timber windows?
Contractors should consider thermal performance, security requirements, acoustic performance, lead times, finish options, installation requirements and sustainability credentials. Early engagement with the manufacturer can help streamline specification and project delivery.
Do you provide technical support for timber window specifications?
Yes. We support contractors throughout the project lifecycle with technical guidance, drawings, detailing advice, performance data and product recommendations to ensure the most appropriate solution is specified.
What are the lead times for bespoke timber windows and doors?
Lead times vary according to project size, complexity and manufacturing schedules. We provide clear programme information at the outset and work closely with contractors to support construction timelines.
