Double glazed uPVC windows and doors offer the same energy efficiency as high performance double glazed timber windows and doors but are more affordable and do not require maintenance. No more stripping, sanding, and painting your frames as uPVC frames will not fade, discolour, rot, or crack over time.

Our efficient uPVC frames accompanied by argon-filled double glazing makes them an unbeatable combination. Aluminium stands no chance against uPVC because, unlike aluminium, uPVC does not transfer hot or cold. An aluminium window frame will feel noticeably warm in the summer and cold in the winter, but a uPVC frame will match the internal room temperature. Aluminium framed windows are less energy efficient regardless of whether they are single glazed or double glazed.

Enertec’s uPVC frames have a steel core that makes our windows stronger than aluminium. You might worry about the steel heating up on 40 degree days, but the clever design of uPVC frames prevents this from happening. The five chambers that surround the steel core of our uPVC window frames and uPVC door frames insulate the steel core to prevent any heat retention in the core.
