Technical Information, Materials & Options


We use local timber merchants that are part of the Forest Stewardship Council ensuring our wood comes from forests that are responsibly managed.

We typically use the following timber:

  • Scandinavian ‘redwood’ Pine
  • Accoya
  • Sapeli
  • Meranti
  • European/American Oak
  • Other timber upon request

Sash and other wood windows can be fitted with different types of glass, from regular double glazing to slim line which suits conservation areas and helps to preserve the original features in heritage sash windows without having wider profiles and glazing bars. Acoustic glass, also known as noise reduction glass, is more popular these days in busy central areas and can reduce the sounds of modern day noise pollution.

Draught proofing as standard

All our windows and doors (with frames) come with draught proofing as standard.

Whilst some other joinery firms use a method of draught proofing by replacing staff beads and parting beads some of which have integral brushes which can work with new windows but not so well with older sash windows.

Our method: to ensure we have the highest quality finish for our draught proofing, we have developed a bespoke method to cut handcrafted grooves at various depths into the moving sashes to allow for the uneven gaps, then fit the brushes into the tailored grooves. The result is a consistent brush seal all around your windows creating a far superior result and the original character of the window is preserved, as the brushes are hidden and the integrity of the window remains intact.

Double Glazing

The benefits of double glazing include:

  • More energy efficient
  • Less heat escapes
  • Reduced heating bills
  • Less noise enters the home
  • More secure
  • Less condensation in the home

Acoustic Glazing

Acoustically insulating glazing can help keep noise outside so you can enjoy your living space in peace and quiet.

Noise pollution is a serious issue, particularly when living in an area with high levels of air traffic or busy roads. Too much noise can be damaging to health (increased stress, disrupted sleep). It can hinder academic learning and concentration.

How does it work?
Noise levels are measured in decibels (dB). A comfortable sound level is around 35dB in daytime and 30dB at night.

Acoustically insulating glass cuts out excess sound and the harmful effects of noise and is particularly effective in buildings near to high streets, urban traffic, motorways, train stations and airports.

The acoustic glass within a double-glazed unit comprises a special interlayer which acts as a dampening core to prevent sound frequencies from vibrating from one pane of glass to the other. This absorbs and weakens sound energy, helping to act as a barrier to noise.

This plastic interlayer also has the additional safety and security properties of laminated glass (see “safety and security glass” section)


Your home should be a place where you can shut out the world and escape the pressures of your working day. By fitting acoustic windows you can keep noise at bay and enjoy your surroundings in peace and quiet.

  • Acoustic glazing forms an effective barrier to external noise allowing you to sleep restfully in a tranquil environment.
  • You can enjoy your home at a sensible noise level so you can relax and unwind without additional stress.
  • Your family can study and concentrate without the distraction of excessive noise.
  • Reduce impact noise, particularly on conservatory roofs when it is raining

Acoustic glass can be combined with many other products for multi-functional glazing, such as thermalinsulation, solar control, low-maintenance and decorative glass.

Paint Options

Our windows and doors come primed as standard unless requested otherwise. We also offer a variety of paint options if you would like a different finish. Please discuss your requirements with us and we can advise you.

  • Water based paint

    Paint manufacturers have formulated new products that cut down on VOCs (volatile organic compounds), which the Environmental Protection Agency warns may have adverse health effects. Traditionally, homeowners had a choice between water-based and oil-based paints, but because they tend to have higher VOC levels, it's important to consider if oil-based paints are for you.

    Advantages of Water-based Paints

    • low VOCs
    • easy cleanup with water
    • quick drying
    • an elastic, flexible finish resistant to cracking
    • stable color over time, without yellowing
