2. Block those drafty windows with acrylic caulk
What’s the use in heating if the cold air is constantly sneaking in through little slots around the frame of the window? To check if this is the case in your home simply grab a lighter and follow along the frame. Wherever the light flickers you have some sealing to do. You can use acrylic latex caulk on those spots. Make sure you remove the old insulation leftovers. Then apply an even amount of caulk on the frames. This works with wooden and plastic frames only.
3. Use self-adhesive insulating seals
This is an another good method for eliminating the cold air flowing into your room around your door or windows. Buy self-adhesive window seals of any material and stick them on the pre-cleaned frames. Be aware that you might need to replace them sometimes as they get torn and less effective over the course of a few months.
