Things effecting energy performance:
There is gas put in between the glass panels which effects the method your energy effectiveness carries out. Argon is more insulating than regular air or a vacuum.
How the glass is treated also impacts the energy efficiency. If you have low emissivity glass with a metallic finish, this allows natural light to beam in and reflects back the heat in the room.
The choice of frame is likewise considerable. UPVC is the most popular material as it is cheap but likewise very good at insulating. Wood is likewise an excellent alternative nevertheless it requires more regular maintenance and painting
Low U, High R Values
The energy rating is chosen through U and R worths. A low U value represents the glass of double glazing letting through a percentage of heat. A high R value highlights the mark of overall energy performance of glass.
Cost of double glazing
There is a considerable difference in expense when choosing between an A+ and C rated windows. However, there is no great distinction in the energy performance with the A+ conserving you ₤ 30 to ₤ 50 in fuel expenses over a year.
