Authentic and traditional charm

Due to their build quality and classic style, our timber sash windows are the ideal choice for conservation areas. If you are looking for traditional design, but require the maintenance free option of uPVC, why not consider our woodgrain option. You would have to look hard to tell the difference.

Why choose a timber sash window?

A timber sash is the most authentic option when you’re replacing wooden windows. The Everest sash is a premium window hand crafted using engineered wood, creating a like for like replacement.

Why choose a uPVC sash window?

uPVC sash offers the perfect blend between modern technology and traditional style. Using innovative mechanisms they work exactly the same as our wooden sash but require little maintenance and certainly no painting. uPVC can be an alternative for the rear of a property when the front has to be timber.

Authentic design

Both our timber and uPVC options are authentic to the traditional sash design, which has been popular for centuries. We have kept with the characteristic deep bottom rail, Georgian bars, central transom and fitch lock.

Smooth running mechanism

There's no struggle to open an Everest sash window. Our uPVC option is fitted with spring balances, whilst our timber sash are designed with spiral balances to ensure smooth running time after time and enabling finger touch opening, making them effortless to open.

Practical design

Sash windows are as practical as they are stylish. They can be opened at either the top or bottom for ventilation. To keep your home secure, a restrictor can be engaged to give ventilation without needing to open your window completely. On the uPVC option, the windows can be tilted inwards for easy access and cleaning.

Create your perfect window from our extensive options

Innovative mechanisms

The opening mechanisms on all sash windows are hidden away but there are still options. The authentic option has cords and weights designed to balance the weight of the sash. Spiral balances work on a modern weighted spring design, allowing for a thinner profile and a larger glazing area.

A choice of timber

Our timber sash is available in Softwood (European Redwood) or Hardwood (Red Grandis) - both of which are responsibly sourced and accredited by the Forestry Stewardship Council (FSC). Our wood is laminated and engineered for layers to specially bond together adding strength and rigidity. For even further durability our softwood is finger jointed to eradicate knots and resist twisting.

Sash horns

On the underside of the top sash section there is an optional component known as a horn. There are two types available; plant on horns and through horns. Through horns offer a richer more authentic aesthetic with the bottom section “butting” against the side sections.
