Product Highlight:Isogenopak Rigid PVC Jacketing

Isogenopak® is a special rigid PVC film for jacketing of insulated pipes. A dry, clean fitting is guaranteed. The inherent curl makes it the ideal material for quick and easy covering. 

Isogenopak® is self-extinguishing and has considerable resistance to acids, alkalis, salts, oil, petrol, aliphatic hydrocarbons and corrosive atmospheres. Iin addition, the material cannot corrode and is virtually impermeable to water vapour. It is unaffected by fresh and salt water and impervious to gases, grease and oil. The chemical characteristics of Isogenopak® are matched by equally good physical characteristics: High longitudinal and lateral tear resistance, high elasticity and shock resistance. Isogenopak® is very light: one square metre, 0.350 mm thick, weighs only about 500 g. Physiologically harmless, Isogenopak® has a light grey smooth surface which guarantees a long lasting elegant appearance. It requires no care or maintenance and also has very good antistatic characteristics. The material has considerable resistance to temperature changes and is stable from -20°C up to +65°C in indoor use. The thermal conductivity l of Isogenopak® is 0.16 W/mK.

Mounting Instructions:

Chemical resistance ensures long product life. Pre-curled Isogenopak® jacketing film is supplied in rolls of 15 to 35 m in length with 1 000 mm as the most common width. The Isogenopak® system is completed by a large variety of pre-moulded bends, t-sections, caps and cuffs. First the insulant must be attached to the pipe without gaps. When using mineral wool sections, loose fill wool can be used to cover the bends and other shapes. The insulant has to be affixed to the pipe consistently. to attach the Isogenopak® jacketing we advise to start with the moulded pieces, e.g. bends (1) and t-sections (2).for straight sections Isogenopak® is cut from the roll according to the circumference to be cladded. Allow an extra 20-30 mm for overlapping. A guide rail for the cutter (3) has proven its worth. Because the pre-curling Isogenopak® clings around the insulated pipe (4) almost by itself. Just little additional adjustment is required. The circumferential seams should overlap by about 20-30 mm as well. Isogenopak® is fixed along the longitudinal seams either by using plastic push-in rivets in distances of about 150 mm (5) or special solvent-based adhesive continuously along the seams (6).

The Beginners Guide to Pipe Insulation: Flexible Foams

Next up in the series we are doing on pipe insulation is "flexible foams"; a category that includes polyethylene and expanded nitrile rubber.

Polyethylene Pipe Insulation
Climaflex pipe insulation is the UK's leading brand for polyethylene pipe insulation. This is the grey foam that most people are familiar with, the kind you would traditionally find in garden centres for example. Polyethylene is the cheapest, widely available product in the market. People very often wrongly assume cheap means poor quality, this is not the case with a brand such as Climaflex. It has a thermal conductivity of 0.034 W/m.K at 0°C which is broadly equal to that of any other flexible foam, and it also has a much higher "μ factor" than other foams, making it more resistant to moisture ingress. These facotrs make it ideal for use around the home, being easy to work with and providing good insulation. 
The material can be purchased in 1m and 2m lengths, and is available in wall thicknesse…

The Beginners Guide To Pipe Insulation: Getting to grip with the basics

Our Beginners Guide series of blogs will look at the common areas of pipe insulation lagging that you will want to look at when choosing your product. This guide will be of most interest to the DIY installers, but some of our later guides will cover more complex products and areas of application.

One of the things we get asked about a lot is what the dimensions quoted for pipe insulation actually mean. You will always see three measurements quoted when describing pipe insulation; Wall Thickness, Bore Size and Length.

In the below diagram, A is the "Bore" and B is the "Wall".

Wall thickness is very simply how much insulation you have; so for example if you have 13mm Wall pipe insulation, then that means you have 13mm of insulation on either side of your pipe. This thickness is very often one of the most important part of your decision; too thin and you might not get the results you are looking for but too thick and it might not fit between your pipe and the wall.


Frost protection for domestic pipes

With the cold weather approaching we thought it would be a good idea to touch on how best to protect your pipes from frost this winter.

When dealing with frost protection on pipes inside a building your aim with insulating them is to delay the onset of freezing for as long as possible; it is not possible to guarantee a pipe will not freeze by insulation alone. The better the insulation, and the thicker the insulation, the longer you will give yourself. Under normal circumstances you aim to give yourself about 8-10 hours protection against sub zero temperatures. With pipes inside a home this is usually long enough to be sure the pipes will not freeze.

Ice formation inside the pipes will lead to an increase in pressure. As the water tries to flow this pressure will increase, and eventually will lead to the pipes bursting. A burst pipe can cause a lot of problems, not least of which is a lot of damage to your property and a lot of expense incurred.

Water regulations state that all water …
