Are you unsure about the pipework insulation wall thickness you need? Are you unsure whether you need extra thick pipe insulation or something a little thinner? If so, you've come to the place. Our vast range of insulation thicknesses gives you all the options you need. 

Different pipes will require different pipework insulation thickness depths depending on the application. Pipelagging.com supplies the full range of insulation in every wall thickness available. We stock all the thermal insulation thickness depths, including refrigerant piping insulation and thickness grades manufactured by vital industry-leading brands, including Rockwool, Armacell, Knauff and Kaimann.

Do you need your plumbing and heating system pipes insulated? The small bore copper pipes commonly used may only need relatively thin insulation, such as 13mm, to provide adequate protection. However, if you have an industrial oil or maritime application with large bore outside steam pipes, a thicker insulation wall will be required - perhaps up to 50mm thick. We have these insulation thicknesses covered and everything else in between!

Pipework insulation thickness options to suit all pipe sizes!

  • Check the minimum thickness you'll need before purchasing. If your lagging is not thick enough, your pipes are likely to lose a lot of heat, which can prove costly in the long run.
  • We stock all the most common sizes and lagging thicknesses, including 13mm, 19mm, 25mm, 32mm - plus many more
  • Check the documentation in the product description to ensure you have the correct insulation thickness for your job.
  • If in doubt, remember that extra thick pipe insulation always wins out, as you'll lose less heat and save money in the long run! 

So choose the recommended pipework insulation thickness that your job needs. Why not call our sales team on 0161 775 1190 if in doubt? They'll be happy to help.
