TL;DR
Weatherstripping is the family of flexible sealing materials, foam tape, vinyl bulb, silicone, felt, spring-metal V-strip, and interlocking metal, applied around the operable edges of doors and windows to block air and water infiltration where two surfaces must still meet and part. Choice depends on the gap and the motion: compression seals for surfaces that press together, sliding seals for sashes that rub past.
What it means
Weatherstripping is the family of flexible sealing materials, foam tape, vinyl bulb, silicone, felt, spring-metal V-strip, and interlocking metal, applied around the operable edges of doors and windows to block air and water infiltration where two surfaces must still meet and part. Choice depends on the gap and the motion: compression seals for surfaces that press together, sliding seals for sashes that rub past. Sealing these moving joints, together with caulking the fixed ones, is the cheapest tier of building efficiency work, with material costs in the tens of dollars against measurable heating and cooling savings.
