UPVC WINDOWS - KEEPING THE INDOORS COMFORTABLE
The combination of uPVC window frames and double glazing makes for highly energy efficient windows. Unlike metals, uPVC is non-conductive, meaning as a window frame it does not transfer heat well and therefore doesn’t transfer temperatures from inside to outside, or vice versa.
It contributes to a more consistent internal temperature for a building, improving indoor comfort and so reducing the amount of energy required to maintain comfortable indoor temperatures.
In Winter as the uPVC frame doesn’t transfer heat from the warm inside to the cold outside, uPVC double glazed windows work well at reducing loss of heating warmth in cold weather.
In Summer uPVC window frames reduce the transfer of heat from outside to inside, keeping the interior cooler and reducing the need for artificial cooling. Cooling a home in summer can use up to three times the energy required to heat it in winter.
The low conductivity of uPVC as a material and the tight seals uPVC windows provide make uPVC windows an excellent choice in energy efficient buildings. Select the links below to view a comparison between PVC and metal window profiles using thermal transfer modelling.

The thermal transfer modelling is provided by AFRC Lab Pty Ltd. The temperature of the internal side of the frames is recorded over a 24-hour period in comparison to the external temperature, based on window design simulations. The source of climate data is ASHRAE climate stations data for 9 February and 15 July 2017.
The sources of data for material/window thermal performance included Therm 7.6 Material Library, Window 7.6 for Glass, Matlab.
* The window system configurations, based on typical available systems, were uPVC: 4 - 14 Argon – 4; Aluminium 5 -10 Argon – 5.
