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

Our uPVC Sliding Sash Windows are 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.

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.

A range of glass options

All our sash windows come with a double glazed Low-E glass as standard but we also offer a range of glass options to improve energy efficiency, reduce noise or to provide privacy.

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.

FAQs

Choosing new sash windows can be a daunting task, so to help you here are some popular FAQs which you might find useful.

  • +
    Can you have double glazed old sash windows?
    Double glazed sash windows are an ideal choice for conservation areas or for those who wish to maintain the look and feel of a period property. You can opt for an authentic timber sash look or a maintenance free uPVC option in a woodgrain finish.
  • +
    What is the sash part of the window?
    The window sash is the part of a window that holds the glass and framework around the glass to keep it in place. Window sashes are extremely important to the overall construction and stability of the window. It is imperative that vinyl window sashes are multi-chambered and reinforced to prevent distortion. If a window sash is distorted, then this could cause issues with leakage and locking of the window itself.
  • +
    How does a sash window work?
    Sash windows are comprised of one or more moveable panes or sashes, forming a frame to hold panes of glass in place. In order to allow the window to move, a glazed panel is balanced by a counterweight that is connected to the window via a sash cord. The sash cord runs over the top of a pulley along the top rail. Wag tails are used to separate the weights and allow a smooth movement when opening the window.
  • +
    What is the difference between sash and casement windows?
    Casement windows normally open outwards, like a door, and are attached with two or more hinges. A casement window is harder to break into when the window is locked due to the lock being constructed within the frame. Casement windows open fully, which means they can provide a better view than a sash window. In comparison, sash windows normally open by sliding vertically. They can either be double hung (where both sashes are operational), or single hung where only one sash can be moved. Double hung sash windows allow for better ventilation in your home than casement windows. Opening both sashes will enable rooms to feel cooler in the summer by allowing warm air to flow out and cool air into the property.
  • +
    What are horns on sash windows?
    The discrete components of a sash window are known as sash horns. These are the short protrusions below the centre bar. A sash horn is the integral part of a sash window that dates back to the mid Victorian period.
  • +
    Can I replace my sash windows with casement windows?
    Before you look to replace sash windows with casement windows it is important you check with your local authority. In some instances, for example if you live in a conservation area or a listed building, it may not be possible to place your sash windows with a modern casement window design. You will also need to consider your local area, to ensure that any change you make is in keeping with your neighbours. Additionally, it is worth considering if replacing your sash windows with casement windows would make the property less desirable for future owners.
