<p>A gutter protection system 10 comprises a water permeable membrane 5 adapted for fitment to a rain gutter so as to extend across the width and at least part of the length of the rain gutter, the membrane incorporating one or more filamental elements 4 (with such filamental elements optionally being filaments, fibres, strips, threads, roving or strands) which draw water into or through said membrane. The filamental elements may be uniformly, randomly, and/or loosely laid. They may be incorporated within, or be situated alongside or underneath, a fine mesh screen layer 5. Ideally the filamental elements operate to interrupt or redirect water flow on said membrane. The membrane may have hydrophilic, sorbent, hygroscopic, wicking, oleophilic and/or self-cleaning properties and may incorporate glass, silica, cellulose or PVA based material. The membrane may be bonded to or held up by a support matrix 6. Also claimed are discrete fixings (3a, fig 2), and houses therefor, for joining one or more sections of the gutter barrier together.</p> |
