Energy Efficient Windows & Doors

Everyone wants their homes to be light and airy, that it why it is so important to install the best windows you can afford and ensure that they are installed correctly. Glazed areas need to achieve the best thermal performance possible to provide a comfortable living environment. Evolved Supplies can offer windows & doors to suit all budgets that meet and exceed the thermal requirements.

It is widely known that the lower the U Value of the window the better the thermal performance and the more insulation in provides, but it is easy to be misled about the various U Value measurements shown across the suppliers.

Some companies will only highlight the lower U Value of the glass (“Ug Value”) rather than the more accurate “Uw Value” which is the combined measurement of all the components of the window, which is what you need to work to when comparing product performance and calculating energy usage.

Evolved Supplies offer a range of uPVC, timber and Aluminium clad triple glazed systems in a range of styles that are all designed to provide excellent thermal and airtightness results, when installed in conjunction with our recommendations for air tightness control.

The Lacuna Folding door is a heat-treated timber door system that offers a functional, elegant and energy-saving design for openings up to 6 meters wide. Lacuna folding doors generously admit natural light.

Our System

Our patented system is built insisting on a high degree of insulation achieved by double insulation seals in the frame and triple insulation seals in doorjambs. Lacuna folding doors are built to function from -60°C to +50°C.
