Casement windows are the classic choice. Understated to look at and easy to use, they are the most popular windows we supply and install. Our casement windows can be fully sculptured or chamfered, so you can choose the style that suits your home.

The label displays the following information:
1. The rating level – A, B, C, etc…
2. The energy rating eg. -3kWh/(m²·K) in this example the product will lose 3 kilowatt hours per square metre per year.
3. The window U value eg. 1.4W/(m²·K)
4. The effective heat loss due to air penetration as L
eg. 0.01 W/(m²·K)
5. The solar heat gain eg. g=0.43
Energy Efficient Windows
PLANITHERM is a new generation of energy saving window glass and the most energy efficient available. Its advanced coating technology reflects radiated heat back into the room, rather than allowing it to escape through the windows. At the same time, PLANITHERM allows free heat and light from the sun to pass through the glass.
Free Solar Heat Gain
PLANITHERM uses advanced coating technology to capture free energy from natural daylight to help heat the home.
The advanced coating reflects heat back into the room, meaning less energy is needed to heat the home to the desired temperature.
Optimal Energy Ratings
PLANITHERM combines with virtually any window frame to achieve a Window Energy Rating (WER) of C and an A rating is easier to achieve.
Haze & Tint Free Windows
PLANITHERM maximises the amount of natural light into the home, without the haze or tint effects associated with some older double glazed windows.
PLANITHERM helps to virtually eliminate internal condensation and reduce draughts and cold spots in and around windows.
