Warm Edge Technology

Energy Efficiency Triple Glazing Edgetech Super Spacer® technology can save you money and improve the energy efficiency of your home.

In a PvcU, Timber or Aluminium window the vast majority of heat is lost through the edges of the window unit, a standard metal spacer bar (usually aluminium) used to separate the panes in a double or triple glazed window acts as a escape route for thermal (heat) energy from your home.

Super Spacer® from Edgetech is 950 times less conductive than aluminium and blocks this escape route keeping more of the heat within your home, which means lower energy bills and a lower carbon emissions.

Other benefits of choosing to install Super Spacer® with your new windows include 70% less condensation formation on the windows, effectively removing the opportunity for bacteria, mould and dust mites to breed which can be harmful to family and friends which respiratory diseases. Super Spacer® also further reduces the noise from the outside world by another 2 decibels.

Super Spacer® can be installed in PvcU, Timber or Aluminium frames so what ever the window style you are looking for you can have energy efficient windows.

 

 




Triple Glazing

Triple Glazing for windows and doors is a great way to reduce the heating costs of your home as well as helping the environment. If you have aspirations to create a passiv haus or passive house building or improve the carbon footprint of your current home triple glazing will make an immediate difference over single or double glazed windows and/or doors.

We have a range of triple glazing options and most of our product range can be supplied in triple glazing as an optional alternative to double glazing. From time to time we have special offers on free upgrades to triple glazing on certain ranges so its worth following us on Twitter and checking our blog for the latest news.

If you would like more information on triple glazing, including an approximate idea of the energy saving bene- fits, we have a number of examples in our showroom of triple glazed products. In addition we have a demonstration machine which provides a live experience of the capabilities of triple glazing to keep warmth indoors.









Ral Colours

RAL colours are a system developed by the German State Commission for Delivery Terms and Quality Assurance (Reichsausschuß für Lieferbedingungen und Gütesicherung) as a colour matching system which is similar to the Pantone® system used in printing.

The majority of our window and door range is available in a wide range of RAL colours enabling our clients to combine multiple products across multiple ranges and ensure a consistent look is achieved by using the same colour sample.






Integrated Blinds

Integrated blinds offer a modern and stylish solution that is perfect for maintaining privacy, controlling room temperature, protecting your furniture from fading and providing a finishing touch to your space. Perfect for bi-folding doors, windows and conservatories, integrated blinds offer a huge advantage over traditional hung blinds – they are maintenance free, removing the headache of cleaning them!

Give you the best protection from heat and glare from the sun, our Uni-Blinds® integral blind system are installed in between the two glass sheets inside the double or triple glazing, ensuring that they will never get damaged, nor need to be cleaned, so you can always enjoy that “brand new” look.

Depending on the system you choose, Uni-Blinds® can be operated manually or electronically. Using a rotational magnetic transmission through the glass, the slats raise, lower and tilt effortlessly using a continuous cord loop that drives the external magnetic device, guaranteeing the units hermetic seal. With the press of a button, the electrically operated system works in a similar way.

you will have no problem finding a Uni-Blind® that fits your room style thanks to the wide range of designs and colours available, ensuring you achieve the best match for your décor.
