Fits 15mm And 22mm Pipes: Flexible wool wrap moulds around bends, elbows, valves and tight corners where rigid foam sleeves cannot reach, suiting both copper and plastic pipework 7.2m Roll Coverage: Each roll wraps approximately 4m of 15mm pipe or 3m of 22mm pipe using a spiral wrap with 50% overlap, so you can plan the run before you start Reduces Heat Loss: Creates a thermal barrier around hot water and central heating pipes, helping keep heat in the water rather than losing it to lofts, garages and floor voids Freeze And Condensation Control: Insulates cold feeds and condensate pipes through winter, while the wool absorbs moisture vapour rather than trapping damp against the pipe surface Quietens Noisy Pipework: Dense wool fibre dampens the ticking and creaking of pipes expanding and contracting between joists and cavities in the ceiling or wall Dust Free To Handle: Sheep wool does not itch or shed like mineral fibre, so a quick job needs no mask, gloves or protective clothing, and offcuts are recyclable Naturally Flame Retardant: Wool fibre has a naturally high ignition point compared with synthetic foam lagging, adding reassurance in lofts, garages, basements and utility rooms
