The main difference that they hadn’t really expected was the noise reduction. Also, the house is much warmer now with double glazing, and their new windows are more attractive.
The house has period features such as wooden panelling at the sides of the windows which used to be covered by heavy curtains to help with insulation – they have now been able to remove the curtains and are enjoying being able to see the wood panelling to enhance the look of the room.
The old windows had secondary glazing and so they could not open the windows properly for ventilation. They were also worried that if they opened the old windows they would break as they were so old! Now, these issues are no longer a problem!
