With our timber windows, there is a choice between two types of wood: Softwood (Redwood Scandinavian Pine) or Hardwood (Dark Red Meranti). Our timber windows are manufactured using fully engineered timber to not only give high performance and longevity, but dimensional stability too. All our timber is certified with full FSC accreditation.

Whatever your requirements for your timber windows, our professional fabricators can create a window bespoke to you. Whether it’s with a certain shape or colour, we can supply a suitable window to match.

Product Overview

Heritage Solution

There is a range of 6 sash horn designs available. With a deep bottom rail of 100mm to create a fantastic replica of original windows. Available in a range of designs such as cords and weights or spiral balance designs, our Timber Sash Windows feature the same benefits of a modern range but with beautiful traditional attributes.

Secured by Design

Welglaze give you the opportunity to request Secured by Design (SBD). Focusing on crime prevention of homes and commercial premises, SBD promotes the use of security standards for a wide range of materials and products, which includes windows and doors helping occupants feel safe and content in their home.
If you want SBD, this must be requested as part of your window specifications, as SBD is not standard.

Our range of Timber Sliding Sash Windows have previously been approved for fitting for listed properties, as well as those governed by the demands of conservation.

Energy Efficient
