Isover Saint-Gobain: A history of innovation

Since taking its first pioneering steps in the manufacture of glasswool insulation in 1930, Saint-Gobain has followed a path of continuous improvement and innovation that has brought it, today, to its position as the world's leading insulation company.

Isover TEL Process

In the early years, the company's focus on production technology and fibre quality led to the development of its world-leading TEL process. This ground breaking process literally turned glasswool production technology on its head, introducing the concept of centrifugal force and hot-air attenuation to produce a completely new generation of glass fibre of a quality and consistency never before envisaged.

As the business expanded, and the company continued to develop worldwide on the basis of its technological excellence, the focus moved to customer service. Every aspect of customer service was reviewed and improved, with particular attention on key issues such as IT, logistics and palletisation. This led to another breakthrough - this time in logistics, with the introduction of the Isover Multipack, a unique and innovative packaging concept that meant, henceforth, all insulating products were available on pallets in standard sizes - a massive bonus for customers, and the company.

In the aftermath of the energy crises, the focus in recent years has been firmly on developing new cost-effective high efficiency insulation solutions for the technical and structural markets, providing customers with solutions that enable them to meet the growing raft of regulations and legislation, with ever increasing levels of comfort and energy saving. Working closely with world-leading industrial companies, shipbuilders and marine engineers, and process engineers and system manufacturers, the company's technical, sales and research personnel have developed world-leading solutions to the widest range of technically demanding insulation requirements.

In every area, innovation continues to be the driver, with new and exciting insulation products continuously expanding their solution portfolio. One of the biggest breakthroughs in recent years has been the development of ULTIMATE . After a research programme lasting more than a decade, this unique generation of glasswool products, which combine the high temperature capabilities of stonewool, with the performance and weight advantages of traditional glasswool, was launched in 2004. Critically acclaimed and multi award-winning, this breakthrough in insulation technology opened up a whole range of new opportunities, particularly for marine and industrial customers.

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.


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…

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 …
