Spring Sash Timber Windows

The spring sash timber window is a modern and more economical alternative to the classic box sash window. It uses a spring-loaded mechanism that allows for a smaller rebate and is often used in new builds where a flush reveal has been detailed by the architect.

Box Sash Timber Windows

Core Timber’s modern-day version of the traditional timber box sash window uses cords, weights, and pulleys to counterbalance the sashes in the traditional way. It is suitable for conservation areas and new builds that capture historical detail while providing modern performance. It’s perfect for projects where architects are looking to create beautiful period properties while also meeting current building regulations and client requirements.
