Over 33% of a building’s heat is lost due to poor insulation of the doors and windows. How can you protect your home from so much heat loss?
If you discover cracks or gaps along your window sill or by your door, the cheapest way and simplest way to fix this would be to use rope caulk and seal the cracks as quickly as possible.
The next step would be to install weatherstrips alongside the full perimeter of your door, as well as door sweeps along the full length at the bottom of the door. For windows, a special lining, that, like weatherstripping, will provide an air-tight area between the window and frame.
Windows that have rotting wood, cracked glass, locks that won’t work, etc, should be repaired as soon as possible. These are just some practical, and efficient ways you can easily use to reduce energy and heat loss.
