Climaflex Pipe Insulation 42mm x 13mm

For 42mm copper on commercial work, Climaflex Pipe Insulation 42mm x 13mm wraps the pipe in a 13mm foam wall. It is closed cell polyethylene in 2m lengths, suitable for heating and water pipes.

Using Climaflex pipe insulation on 42mm

42mm turns up in plant rooms, school boiler houses and the risers of larger buildings. Pipe that big carries a lot of heat, and lagging it is one of the cheaper ways to cut running costs. A 13mm wall is a good all round choice. It gives noticeably more cover than 9mm without making the run too bulky for standard brackets. On cold mains it also helps keep condensation down.

• Pipe outside diameter: 42mm
• 13mm foam thickness
• Each tube is 2m long
• Closed cell polyethylene, for hot and cold lines

Slide the tubes on before the last fittings go in, where you can. On pipe already fixed, cut a straight slit along the tube, open it and push it over. Keep the ends pushed hard together. If you want joints that stay closed, glue or tape them. A sharp knife gives the cleanest cut, and mitred joints at bends stop cold spots. Do not forget valves and tees, as gaps there let the heat out.

Common Questions

Does Climaflex 42mm x 13mm fit 42mm copper?

Yes, it is sized for pipe that measures 42mm across the outside, so standard 42mm copper takes it. Check older steel pipe with a tape, because it may not match.

How much difference does lagging a 42mm main make?

A large bare pipe gives off a lot of heat into rooms that do not need it. Lagging keeps that heat in the water, so boilers work less and cold mains stay cooler too.

Is the 13mm wall the right choice on 42mm?

It is a good middle grade: more cover than 9mm without taking up as much room as the heavy walls. Go thicker if the pipe passes through cold, unheated space.
