Home improvement insulation designed to reduce heat loss and prevent freezing on domestic pipework. Enjoy peace of mind during cold snaps when external and exposed plumbing stays protected. Is Climaflex Foam Pipe Insulation Lagging Roll the right solution for 22mm pipes and outdoor runs?
⚡ At a Glance
- • Thermal Performance: Closed-cell foam slows conductive heat loss and helps maintain pipe temperature on small-diameter runs
- • Best for: DIYers, landlords and tradespeople insulating 22mm domestic pipework, indoor or exposed outside runs
- • Not ideal for: Large commercial pipework or systems that require specialist high-temperature insulation
Closed-cell polyethylene foam, 9mm thick, supplied as a 5-metre roll with 1m lengths. Pre-slit design and water-resistant construction suit exposed runs and outdoor use, and material is CFC and HCFC free.
Prevents Freezing – with closed-cell polyethylene foam
Closed-cell polyethylene contains sealed gas pockets that reduce heat transfer and resist water absorption. The foam structure limits both conductive and convective losses along the pipe surface.
Reduced heat loss helps keep 22mm pipework warmer for longer and lowers the chance of freezing. Suitable for vulnerable exposed pipes during cold weather.
Quick, No-Fuss Fitting – with a pre-slit flexible roll
A longitudinal slit runs the length of the tube, allowing the insulation to be wrapped around pipes without dismantling joints. Highly flexible foam conforms to bends and fittings without tearing.
Faster DIY installation on straight runs and around bends, saving time on maintenance. Ideal for retrofit jobs where shutting down systems would be inconvenient.
Weather-Resistant for External Runs – thanks to non-absorbent material
Material is described as non-absorbent by water, making it suitable for outdoor usage. Product is CFC and HCFC free, indicating an ozone-depletion potential of zero.
Remains dry and dust free on exposed sections, reducing degradation and the need for frequent replacement. Environmentally safer composition compared with older foam types.
