How to accessorize for maximum effect - Part 2: Outdoor Use

Continuing our series looking at the use of insulation accessories, in this entry we will be looking at how to protect insulation for external use.

The basic problem with the majority of thermal pipe insulation products is that you cannot use them outdoors; notable exceptions are premium products such as Eurobatex R which can be used externally without painting due to its protective polyolefin skin, but comes at a price premium compared to other products, or high temperature EPDM rubbers such as Eurobatex AT which are inherently UV stable but lacks the thermal values to be used for frost protection on smaller pipes (this product is intended mainly for use on solar pipework where the thermal requirements differ from conventional thermal insulation products).

These products aside, the more common closed cell flexible foams such as Eurobatex Pipe InsulationClimaflex Pipe Insulation or Armaflex Pipe Insulation will degrade in sunlight. Typically, polyethylene pipe insulation (such as Cl…

So, lets begin by looking at basic products for sealing insulation. Why seal insulation? Basically, if you have open seams or butt joints then this is a point of weakness - letting heat out, or cold in depending on your point of view.

Probably the most low tech solution for sealing domestic grey pipe insulation (eg Climaflex) would be a product like Clima-Clips which you simply pinch into place along the seams or but joints - a good rule of thumb would be to use 2 clips per m…
