Glass and Glazing

• 

  All our glass units are produced in accordance with BS EN 1279 part 2 (previously BS5713) and are kitemarked no. KM279077 registered August 1994.

• 

  Every pane of glass is toughened and compliant with BS EN 12150 (previously BS6206 Class A). Each sealed unit has a 'U' value of 1.7 in the windows and doors.

Glass roofs are true self cleaning and have a 'U' value of 1.1 together with light transmission of 44% and 0.38 SHGC**

Low 'E' Glass Benefits

Low emissivity glass is recognised by the Energy Saving Trust as significantly reducing heat loss. It can help windows achieve the Window Energy rating level C that they need to obtain Energy Saving Recommended status. Energy Efficiency is an Energy Saving Trust Initiative backed by Government.

What makes Low 'E' Glass the ideal solution?

Low 'E' Glass usually forms the inner pane of a double glazing unit, and has a special 'low emissivity' (low E) coating which is a good relector of long wave radiation (heat). This allows less heat to escape through your windows because it reflects heat from fires and radiators back into your home.

At the same time low 'E' Glass lets the sun's heat through your window contributing to its energy efficiency. This free heat from the sun is known as passive solar gain. So, whilst offering positive benefits for the environment, this alos has great benefits for you.

Why the Government insists you have energy efficient windows

In recent years, a great deal of importance has been placed on damage to the environment, and in particular the harmful effects of 'greenhouse' gases. As part of the Kyoto agreement, the Government has committed to reduce the amount of these gases the UK produces. One way has been through stricter Building Regulations concerning energy efficiency.

'Low emissivity' (low E) glass is designed to reflect heat back into a building, greatly improving its thermal efficiency and also maximising the use of the available heat from the sun, thereby helping to meet these new regulations.
