The u-value of a window is a measurement of the rate of heat loss which indicates how well the windows are keeping the heat in. It is expressed as watts per metre square kelvin (w/m2K). The lower the u-value, the better the thermal performance of the window.
The B.F.R.C. (British Fenestration Rating Council) Window Energy Rating Scheme is a voluntary scheme used by the glazing industry in which the whole window (frame and glass) is assessed on its efficiency at retaining heat. The scheme consists of bands from A to G, where A is the most efficient and G the least.
Aluplast Ideal 70 has achieved the highest window energy rating A. Due to the excellent performance of the profile system, in combination with top quality glass specification, Halpin Aluminium & uPVC can easily achieve window energy rating A with double glazing, both for white and coloured (foiled) windows.
Insulating your home is one of the most effective ways of improving the energy rating of your home. Poorly insulated windows and doors account for 25% of heat loss in the average home. Installing energy efficient windows is an effective way of reducing your energy bills and keeping your home warmer and quieter.

Double Glazing V Triple Glazing
The best performing double glazed unit has a u-value of 1.1 w/m2K which is a very good unit. With triple glazing, it is possible to achieve a u-value of 0.7 w/m2K. Expertly designed, manufactured and installed triple glazed windows will significantly reduce energy usage. Triple glazed units deliver enhanced performance at an affordable price.
By using the most energy efficient products, windows will:
* Use less energy
*Save on heating
*Be more comfortable all year round
*Reduce carbon footprint
*Add value to your property
