It matters where you attach your seals

Correctly weatherproofed windows, doors and their joints reduce the feeling of draft and so reduce the energy spent on heating the apartment. In addition to weatherstripping, you should periodically renovate your window frames and doors. Their correct maintenance also affects living comfort and saves money when you won't have to change the whole window. Correctly maintained frames also help when attaching the weatherstrips, which may detach from dirty or extremely curvy frames.
