This wooden sash window on hidden springs offers the timeless up-and-down sliding action with completely clear glazing — no bars, no grid, just open glass and slim timber lines. It suits renovations and newer homes alike, wherever you want maximum daylight with a traditional sash silhouette. Made to order in the UK, prices start from £449+VAT.

Clear glazing for maximum light

With no glazing bars interrupting the pane, each sash is a single sheet of energy-saving glass. Rooms feel brighter, views stay unbroken, and cleaning is quicker. This uncluttered style works particularly well in Victorian terraces that originally had plain two-over-two sashes, as well as in modern builds where a minimal look is the goal. If you later decide you want divided panes, our sash window with a vertical glazing bar offers that detail.

Spring balances in a slim timber frame

Concealed spiral balances counterweight each sash, so the window slides smoothly and holds at any height without the deep box frame that weights require. Explore all our timber sash windows on hidden springs, and pick engineered pine, softwood or hardwood such as meranti or oak, glazed to a U-value of 1.4 W/m²K.

Frequently asked questions

How do hidden spring balances work?

Spiral balances are spring-loaded tubes fitted discreetly inside the frame on each side of the sash. They counterbalance the weight of the glass and timber, so the sash slides up and down with light fingertip effort and stays exactly where you leave it.

Are spring sash windows as good as windows on weights?

They perform the same job with a slimmer frame and simpler installation. Weights remain the choice for strict heritage authenticity, but for most homes spring balances offer easier maintenance, as each balance can be swapped individually in minutes.

Can I have glazing bars on this window?

This model is designed with clear, open glazing. If you want divided panes, choose our Georgian sash on hidden springs, which adds a full astragal bar grid to the same spring mechanism.
