- What is PLANITHERM?
Planitherm is a new generation of energy saving window glass that uses an advanced coating to retain more internal heat and to absorb free energy from natural daylight, designed for use in a double glazed unit. That means lower energy bills compared to standard windows but for about the same cost.
Using the latest technology, planitherm has a unique combination of metallic layers, which reflect heat back into a room, to keep heat within the building. At the same time maximising the amount of natural light coming in. as more heat retained, it means less is required to warm up the home to the desired ambient temperature, in turn lowering energy consumption.
2. Why should i have planitherm installed in my windows?
There are a number of reasons why you should have planitherm installed in your windows. Firstly, government building regualtions require us to use CO2 emissions and protect the environment. Planitherm is the most energy efficient window glass available. Using planitherm is an easy and efficient way of complying with these regualtions whilst offering a number of benefits.
- Free Solar Gain - Planitherm uses advanced coating technology to capture free energy from natural daylight to help heat you home.
- Thermal Insulation - The advanced coating reflects heat back into the room, meaning less energy is needed to heat the home to the desired temperature.
- Optimal Window Energy Rating - Planitherm combines with virtually any window frame to achieve a window energy rating (WER) of C and an A rating is easier to achieve allowing compliance with building regs.
- Haze & tint Free Windows - Planitherm maximises the amount of natural light into the home, without haze or tint effects associated with older double glazed Windows.
- Eliminated Condensation - Planitherm helps to virtually eliminate internal condensation, reducing draughts and cold spots in and around the windows.
3. I have double glazing; does this mean my windows are energy efficient? Of course all old, uncoated, double glazing offers a limited level of heat retention. However, Building Regulations now state that an energy efficient window glass must be used in all replacement windows and a double glazed unit containing planitherm is on average 40% more thermally efficient than standard non-coated double glazing.
4. Is the coating on the glass permanent? Yes, the coating is permanent and hermetically sealed with the glass unit so will last the lifetime of the Windows.
5. If planiterm lets the sun in, does it let anything out? The glass has a very thin, transparent metallic coating that reflects heat back into the room, rather than allowing it to escape through the windows. At the same time it allows heat from the sun to pass through the glass to warm the room, meaning it takes less energy to maintain a warm comfortable home.
6. Is the performance of planitherm proven? Yes, the performance of planitherm meets the requirements of Class C of European Standards BS EN 1096 and carries the relevant CE marking.
7. What is a Window Energy Rating? - A Window energy rating (WER) is a system for demonstrating the energy efficiency of a Window. The labeling used is similar to those seen on applications such as a fridge or freezer offering an easy method for comparison. To check a Windows energy efficiency before you buy, look at the energy label. The ratings range from A to G with a C- rating being the minimum rating required for compliance with currant building regs. It considers three aspects of performance.
- Amount of heat loss
- Amount of solar heat gain
- The air leakage of the assembly
