Touchstone Glazing Solutions Ltd

| 18.09.17

With over 25 years worth of experience in the traditional leaded light industry, we developed Touchstone Insulead glazing system (Patented) to specifically overcome the problem of double glazing windows in a heritage building situation. No modification to the existing fabric of the building is required as the Insulead glazing fits where the original was located, and is made using only traditional materials.

Directly glazed into the original stonework

An appearance virtually identical to the original

Touchstone Steelyte opening casements are uniquely designed and constructed from Stainless Steel. Thermally broken and fully weather stripped, they take a full 28mm unit. They combine the narrowest of sight lines with security, durability and elegance. The steel is all but immune from corrosion. Whilst powder coated for the heritage market openers can be supplied polished for modern building applications.

Stainless steel and effectively maintenance free

Due to Touchstone Insulead’s unique ability to take any thickness of unit (28mm standard) it is possible to incorporate specialised glass for the purposes of security, UV filtration, energy conservation and sound inhibition all whilst maintaining a traditional appearance. It is even possible to use the original glazing either within the double glazing or mounted in front or behind as a decorative screen.

Extensive range of glazing options including original

Shapes and out of square windows easily accommodated

Touchstone Insulead has been specifically designed for double glazed units. It is fully drained and thermally broken. In the unlikely event of water ingress through, for example stone porosity, the inbuilt drainage channels allow the water to exit to the outside via weep holes. Combined with warm edge spacer bar technology the highest level of insulation is possible.

Fully drained and thermally broken

  • Double Glazing for heritage buildings
  • Steelyte Stainless Steel Opening Casements
  • Insulead Patented Frameless Double Glazing
  • BFRC “A” Rated
  • Shaped and Out of square windows easily accomodated

Masterframe Windows Ltd

| 18.09.17

Masterframe has been in business for 31 years and is the only true “specialist” sash window manufacturer in the country.

We are all about sash windows, however, although you’ll see many of our photographs used on the GGF sites and we’ve been GGF members since 1997, you won’t find us on myglazing.com because as a trade manufacturer (we don’t install) we cannot be listed.

Each year we must stay ahead of the competition, so each year we develop new and exciting features like Timberweld®, Georgi-clips® and bespoke GPR sections.

Dedicated to retaining the elegant proportions through continuous innovation, creative flair, passion and design, you can be confident we set extremely high standards with excellent craftsmanship and attention to detail.

You’ll find we’re not cheap; indeed we’d go so far as to say we’re considerably more expensive than other sash window producers, but there are good reasons for that, not least because we include far more.

We’re happy to explain differences, the standards we set ourselves, the attention to detail we insist upon and gladly provide a wealth of testimonials from clients who trust us with their orders.

You decide the specification which suits your needs best, the benchmark you expect new windows to attain, using only the features that you believe are right for your project. Our job is to help you understand what the important features are and the choices you have, like:

  • Patented Timberweld® technology for perfectly sealed corners
  • Choice of three trade ranges with exclusive profile systems
  • Exclusive London sash and frame design
  • A rated for energy efficiency
  • Secured by Design

We would be delighted to help you further with your project.

  • Low maintenance PVC-U sash windows
  • GRP fibreglass windows
  • Box Sash Vertical sliders
  • Suitable for Conservation areas
