(5) Pipe Insulation Wool Felt Hair Pipe Wrap Lagging 7M Roll 15mm 22mm 28mm

(5) Pipe Insulation Wool Felt Hair Pipe Wrap Lagging 7M Roll 15mm 22mm 28mm Description

Pipe insulation - The more you buy, the less you pay!

Each roll is 7.3 metres (24ft) long x 90mm wide. Thickness generally 5 to 8mm. Multiple layers can be wound around the pipe(s) for additional insulation.

This is an environmentally friendly alternative to typical polythene foam pipe insulation. Used for general pipe insulation to give frost protection. Also to help keep heat inside the pipe which helps to save energy and prevent overheating of adjoining spaces.

Construction – recycled jute and other fibres needled into a polythene membrane

Fiber composition - approx. 50% natural jute fibres , 50% recycled wool / nylon fibres.

This product passes test for flammability to BS4790, with a low radius of effects of ignition. Simply this means that this product is not highly flammable, but it will burn is exposed to an existing fire.

As this product is partially made from recycled wool, the colour may vary slightly from roll to roll (does not affect the quality of insulation).

Customer Reviews

• Marvellous lagging, far better than the foam insulation, as not only does it keep the pipes frost free but also awkward to insulate plumbing joints and bends.
• Ideal for the area used - water pipes under caravans where access can be difficult.
• Ideal for wrapping tanks and pipes you can't get to easily. Strong too doesn't break
• lightweight easy to use

WHY USE PIPE INSULATION?

Energy Conservation

Pipe insulation is also very important for keeping heat in the pipes and ensuring that it is conveyed to its destination without excessive heat loss. Pipes may run through cold spaces such as garages and roof voids where you don't want heat loss into these spaces as this will make the heating system less efficient. There is also good reason to insulate heating pipes running through heated spaces to prevent overheating of rooms within properties. This way heat is delivered directly to the radiators with thermostatic controls in habitable rooms without excessive losses in circulation areas. In larger buildings secondary hot water circulation and heating pipes must be insulated to prevent overheating in corridors where pipes are often located as this greatly improves the efficient of the system especially where the hot water heating boiler may not be as efficient as the space heating boiler. Rule of thumb - the bigger the pipe diameter the thicker the insulation should be for effective insulation.

Energy Conservation applications:- Insulation of all pipes in garages and roof voids or other unheated spaces, prevention of overheating by insulating pipes within the building. Some example pipe heat loss calculations for 22mm copper pipe are; no insulation=61 watts/ meter, 9mm insulation=11.3w/m, 13mm insulation=8.3w/m. So if you had 10 meters of flow and return pipes in a garage or roof space, your would giving over 600 watts of heating to your garage/ loft which would be wasted energy.
