Timber


A variety of timbers are used by Timeless Sash Windows and this decision is made subject to the use exposure of the product. Accoya with its 50-year anti rot warranty is a popular and versatile choice of species.

Carefully selected Mahogany or Iroko are also excellent choices for complete new projects.

We have also used high grade redwood, larch, cedar, poplar and douglas fir when there is a special requirement. Our operators are equally competent in using all the various species of timber available.

As a conservation specialist we can also use salvaged timber in our restoration projects

Glazing


At Timeless Sash Windows due to the broad spectrum areas we cover, we use many different glass options.These options vary on the client's needs and requirements. We use glass manufactured by both Pilkington K and Saint Gobain.

Our double glaze unit varies from a 12mm unit, 4 mm float, 4mm krypton gas and 4mm float to a 28mm unit consisting of 4mm float-20mm Argon -4mm float. These are multiple choices of double glaze and we are happy to advise which suits you project best. All our double glaze units contain a warm edge spacer bar manufactured by edge-tech. All our units are Low “E” and contain safety glass where required. Our single glazing range varies on requirement-from 4mm float to cylinder to salvage glass. Again our clients needs determine the type of glass used.

We are also familiar with working with Spacia glass and have successfully used this on a number of projects. It is a specific type of laminated glass which comes from Japan. Its u value is lower than that of traditional double glazing.


Glazing Bars


We are delighted to have recently launched our latest Timeless Slim Glazing System. This allows us install slimline double glazing using a glazing bar as slim as 16mm. This can be done with new windows or retrofitted into Georgian windows.
There are many various types of glazing bars, some include:

  • Ovlo
  • Lambstongue
  • Splay
  • Bishops hat

We can match any other profile your project require.

Draught Proofing


We use Schlegel for our draught proofing. There are many benefits to using this type of draught proofing. Here are some of these listed below:

• Excellent memory – returns to original shape after compression
• Stability – low / no stretch gained by rigid insert or glass fi bre internal cord
• Easily compressed – low compression forces, unaffected by temperature variance
• Acoustics – outstanding acoustic performance
• Thermal conductivity – unrivalled thermal performance
• Paint and stain proof – properties unaffected by standard paints and stains
• Stabilised – unaffected by rot, fungi, UV-light or ozone
• Colours – white, black, brown, grey and many other options
• Temperatures – wide operating range under extremely cold and warm weather conditions.
• Within Timeless Draught proofing system we use schlegal seals. The installation of where the seals are located are critical.
• A-Rated logo to go beside a-rated text.

Air Leakage


Our use of Schegal draught seal products in certain critical locations allow us to achieve excellent air leakage results and these are unrivalled within the sash window industry.

Ironmongery


We offer a variety of traditional and modern ironmongery be it chrome or brass. These can all be selected during consultation with you to suit your needs.

The ironmongery used in Sash Windows is Fulton and Bray however we are more than happy to source specific ironmongery for our clients.

Finishes


We at Timeless Sash Windows can paint the windows to the preference of the client’s needs. We use Teknos paint for our windows always working with the colour scheme the client has in mind for their windows.

Teknos offer a wide range of high-quality paints and coatings for the manufacturing industry, building professionals and consumers, focusing sharply on the quality and performance of their products.

A-Rated Windows


At Timeless Sash Windows we have developed an A RATED sliding sash window. Each window we make is A-Rated by the BFRC which is the UK’s national system for rating the energy efficiency of windows and is recognized with current building regulations.


The three components that are tested are:

  • U-Value - A U- Value is a measurement of the rate of heat loss indicating how well your windows are keeping valuable heat in.
  • Solar Factor - Solar factor is the increase of temperature in a room from solar radiation (sunlight) the amount of solar gain increases with the strength of the sun.
  • Air Leakage - Hard Wood Certificate
    Air leakage is the amount of air that passes from one side of the window to the other.
