The diameter of the pipe that this insulation will fit around. In the example below this is a 15 mm pipe. The most common sizes are 15, 22 and 28 mm Exposed external pipework in likely to freeze in winter when the air temperature drops below freezing and this can cause the pipes to burst. Pipes in Lofts Cellular glass insulation was first developed over 60 years ago. It was discovered by making glass, then destroying it and then by baking the glass powder (with certain additions) a cellular glass form or ‘bun’ could be created. The bun is 100-percent glass with both insulating and flotation properties. The glass composition makes it moisture, high heat, and fire resistant

hair felt lagging is not enough of a protector either concrete & screed will eat straight through that, Generally you will find that there are two numbers written of the lagging. These refer to the size of the relevant sizes: There are other options which can also be used, although we will concentrate on the split foam type in this project. These other options are relatively self-explanatory to fit once you have the concept of fitting which we explain below. When you have all the tools you’re ready to fit the insulation to the pipes. Using this split foam insulation this is relatively easy; split the insulation and feed it around the pipe so that the pipe is surrounded by insulation:

It’s made from a non-water soluble, heat resistant material that is easy to install and remove. 11. What is pipe lagging made from? A: Pipe lagging is cheaper and easier to install than other materials, including thermal caulk tape, thermo-bond insulation, and mineral wool. Using 22mm copper with felt insulation should make the pipes quite sturdy when they are laid, but the run is 6M and I don't want rattling pipes. In terms of the tools you are going to need, here are the likely ones that you will need for fitting pipe insulation:A: Pipe lagging can be applied at any time but we recommend that you apply it when the pipes are wrapped and the ducts have been put into service. 8. Why is pipe lagging best for hot water pipes? A: Lagging is the name used for pipe insulation, sealing tape, heater cable and pipe wrap around Australia. Lagging generally refers to thermal insulation that is applied to pipes and cables to reduce heat loss or gain. 2. Why choose pipe lagging over other forms of insulation?

A common use of pipe lagging is to provide thermal insulation for water pipes such as those that carry hot or chilled water to a building.

A: Pipe lagging provides excellent protection against corrosion. It is made from a non-water soluble, heat resistant material that is easy to install and remove. The various materials allow for varying amounts of permissible temperature exposure, with some able to withstand temperatures as low as -150 degrees Celsius (Polyurethane Foam) or as high as 1750 degrees Celsius (Polyurethane Foam) (Refractory Fiber). Those are typically employed in a more industrial setting. Polyethylene, stiff foams, flexible elastomeric foams, cellular glass, glass wool, and mineral wool are just a few of the materials that can be used to make pipe lagging. Regardless of the material, a bulk of the regularly used pipe lagging comes pre-formed. The cylindrical-shaped kind is available in standard sizes as well as made-to-measure options. Pipe lagging insulation is typically made from a felt, wool, or other fabric impregnated with a heat-resistant material.

In principle this is all that there is to is, however there are a number of areas that might cause you difficulties. Here’s how to deal with them: Joining lengths of insulation As we mentioned you will typically use the foam type insulation which have already be cut with a slit so that it can easily be fit over a pipe:Make sure that you insulate the whole length of the exposed pipe work, including any couplings, joins and event taps. Top Tip: Use a bread knife of similar serrated knife for cutting the foam insulation as it is much easier. Sturdy scissors can be helpful for notching out insulation (see below how to insulate bends in pipes). Asbestos Insulation; this is one to watch out for rather than use. Older types of lagging used to contain asbestos, so handle with care. For more information on dealing with asbestos see here
