A weatherslate comprises a planar portion and a sleeve having a wall, an inlet and an outlet. The sleeve extends away from a surface of the planar portion. The sleeve may be flexible. Alternatively the sleeve and planar portion may be formed from a single material. The flexible sleeve wall may be tapered so that the outlet is smaller than the inlet to form a water tight seal with for example, a flue. The sleeve may be in the form of a concertinaed boot or gaiter. |
