Spring Balance Sash: Conservation

Our sash windows are manufactured from premium, sustainably sourced timber, including pine, sapele, European oak, Accoya, and engineered hardwoods such as Red Grandis.

Additional timber species can be sourced for bespoke applications, subject to availability and suitability.

Refer to our Design Guide for further information on timber specification options.

Where required, trickle vents are fully concealed through the head of the frame.

They are invisible on both the internal and external faces of the product.

Working closely with leading component manufacturers, we carefully select high-quality hardware that delivers both excellent performance and refined detailing.

A PAS24-tested window is available, compliant with Part Q of the Building Regulations.
