1.1.1 Use silicon, putty or draught excluder to reduce air infiltrations throguh window and doors
Description
Simple and cheap means may be used as silicone, putty or draught excluder (self-adhesive strips of insulation material which are set on the edge of doors and windows to avoid the entry or exit of air) to cover the cracks and decrease air infiltrations that can be produced through the doors and windows of the building.
Benefits
The energy consumption reduction potential is considered to be high (up to a 40%)
- Reduce heat losses and air infiltration
- Easy, fast and cheap installation (it is not necessary to dismount the window)
Limitations
- Durability of solution
- To obtain better performance, in case of old models of windows, it is recommended to change the entire window (frame and glass)
- Improve airtightness can lead to more condensation because moist air is trapped in the house
Economic assessment
Low investment. It depends on the particular characteristics of each building and the means used. For example, the use of draught excluder is very simple and cheap, around 0.5 €/m2.
