2.1.15 Installation of efficient windows (solar control double glazing with aluminium frames with thermal break)

2.1.15 Installation of efficient windows (solar control double glazing with aluminium frames with thermal break)

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 solar control double glazing and aluminium frames with thermal brake. Solar control glasses have the property of reflecting part of the energy of the received solar radiation, decreasing the amount of energy that passes through the glass. A typical transmittance of this type of windows is U=1.8 W/m2K.

Benefits

  • Airtightness improved

  • Sound insulation

  • Safety

  • Easy cleaning

  • The aluminum frame is available in various colors

  • Aluminum is a strong and rigid material, its properties do not change with the weather and its rigidity is ensured at high and low temperatures

  • Solar control glasses cut utility costs by 30% to 40%

  • Solar control glasses can block 99% of UV light that fades furniture

Limitations

  • The energy consumption for aluminium manufacturing is high.

  • Double glazing cannot be repaired

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

  • The most common complaint of this frame is that in winter the aluminum sweat

  • It is a cooler material than wood and PVC

  • Over time, the aluminum can become corroded

  • Can reduce valuable solar heat gain in colder climates

Economic assessment

Initial investment: high. The price varies greatly, depending on the size of the window and manufacturers. Energy costs are reduced.
