2.1.11 Installation of efficient windows (double glazing with PVC frames)

2.1.11 Installation of efficient windows (double glazing with PVC frames)

Description

This measure consists in the replacement of inefficient windows (e.g. aluminium frame without thermal brake and single glazing) for an efficient one with double glazing and PVC frames. A typical transmittance of this type of windows is between U=1.7 W/m2K and U=2.9 W/m2K, better performance than inefficient windows which have a typical transmittance higher than 4 W/m2K.

Benefits

  • Airtightness improved

  • Limited condensation

  • Reduce heat losses

  • It allows a perfect soundproofing and it reduces noise pollution

  • It is a durable and resistant to cold and air material, very suitable for cold areas

  • It does not need any special treatment for its conservation, just wash it with soap and water without risk of rot or damage to the material

  • There is a wide range of colors, although white is the most widely used color, there are imitation wood, without a too high price

Limitations

  • Double glazing cannot be repaired

  • During the summer months, trapping heat inside glass panes can lead to a suffocating and uncomfortable room

  • PVC frame is more expensive than the rest

  • PVC with high temperatures can be deformed

  • PVC is a polluting material

Economic assessment

Energy costs are reduced.
