Energy Efficient uPVC Windows & Doors
Case Study
Family home becomes 15% more energy efficient
Below is an example of the benefits Senator Windows bring to a home. Our customer replaced old, inefficient windows and doors in their newly purchased home, instantly adding comfort, updating the look and adding value to their property while, in the process, reducing their overall energy bills. Their energy consumption is now 15% lower, compared to that of the previous owner. Read how we did it below.
The Problem
This detached house was bought in 2021 to accommodate a growing family. The new owners undertook a BER assessment which gave it an ‘F’ Energy rating, with a high energy consumption rate of 391.2 kWh/m²/year. As glass is responsible for more heat loss than most other building materials, they decided to replace the old, inefficient uPVC doors, and the double-glazed windows which had a high U-value of 2.7 W/m²K.
The Solution
After discussing all the options, the new owners decided to upgrade to uPVC Senergy Elite Windows. A-rated Senergy Elite windows are triple-glazed and have a U-value of 0.9 W/m²K, significantly lower than the old windows. This U- value reduction is largely due to the materials used. Pilkington K Glass S (low-e) is used in the inner and middle panes, while Pilkington Optiwhite glass (low-iron) is used on the outer pane. The space between is filled with 90% Argon gas, with a warm edge spacer bar for optimum energy efficiency. The old doors were replaced with Senator triple glazed uPVC residential doors. The front door is a thermally efficient, triple glazed Sentinel Composite Door, with a U-value of 0.98 W/m²K, including the frame.
The Results
After all the windows and doors were replaced, a second BER assessment was carried out. It showed that, by changing the windows and doors alone, the F-rated home was raised to an E1 energy rating, while the energy consumption went from 391.2 kWh/m²/year, down to 332.86 kWh/m²/year – a reduction of 15%.
*15% energy saving is based on the case study above.
