Insulation News: NEW UKTFA GUIDANCE SHOWS STONE WOOL OFFERS ‘BEST-IN-CLASS’ FIRE PROTECTION


NEW UKTFA GUIDANCE SHOWS STONE WOOL OFFERS ‘BEST-IN-CLASS’ FIRE PROTECTION FOR TIMBER FRAME PROJECTS



A new classification system for insulation products, launched by the UK Timber Frame Association (UKTFA) and backed by the Health & Safety Executive, has identified Stone Wool as the only insulation product to achieve its highest ‘Type 3’ rating. The system uses independent test results included as part of the UKTFA guidance ‘Design Guide to Separating Distances During Construction’ which has been created to help building designers to mitigate the potential for fire spread between buildings during the building phase of timber frame projects.

A new classification system for insulation products, launched by the UK Timber Frame Association (UKTFA) and backed by the Health & Safety Executive, has identified Stone Wool as the only insulation product to achieve its highest ‘Type 3’ rating.  The system uses independent test results included as part of the UKTFA guidance ‘Design Guide to Separating Distances During Construction’ which has been created to help building designers to mitigate the potential for fire spread between buildings during the building phase of timber frame projects.

The new classification regime, which should be used to compliment the main UKTFA guidance, ranks insulation products by ‘Type’, based on the UKTFA’s review:

Type 1 - Melts under heat and has combustible gases
Type 2 - Shrinks under heat and may have combustible gases
Type 3 - Maintains volume and does not combust

The insulation products listed below have been tested and submitted to the UKTFA product review board which has classified them according to F1 build performance levels as follows:

Manufacturer/Product
Application
FI Build Performance Level
Kingspan Therma TW55
As an insulation installed between FR Build studs
Type 2
Kingspan Kooltherm K12
As an insulation installed between FR Build studs
Type 2
Glass Wool (MIMA)*
As an insulation installed between FR Build studs
Type 2
Stone Wool (MIMA)*
As an insulation installed between FR Build studs
Type 3

Products manufactured by companies that are not members of MIMA are not accepted for use by the UKTFA until they appear on this list.

Thomas Heldgaard, managing director at ROCKWOOL UK commented: “As the leading Stone Wool manufacturer, we have always known that ROCKWOOL’s insulation solutions offer ‘best-in-class’ fire protection for building projects. We welcome this new guidance from the UKTFA as an important way for the timber frame industry to design projects with fire safety in mind. We are delighted that Stone Wool is the only insulation to achieve a ‘Type 3’ rating and look forward to working with the timber frame industry to produce technically innovative, sustainable and firesafe buildings for years to come”.

To help guide designers through the new guidance ROCKWOOL has produced a simple Technical Briefing available here: www.rockwool.co.uk/timberframe.

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 …
