Thatch Fire Protective Membranes

There are many fire membranes on the market ‘suitable for use beneath thatch’.

Are they suitable? What’s the difference?

Nearly all fire membranes are PU (polyurethane) coated.

PU28 is still often asked for and is widely used to describe fire barriers within the thatching industry. PU28 was used as a development code for a new membrane product and this code has stuck with many membranes to this day.

There are many formulations for a PU coating, some more economical than others. Some are solvent based, while most standard PU finishes would certainly fail a smoke & toxicity test.

A membrane, PU or other may have a BS type test. What test? The testing it carries may not be an indicator of a product’s quality as some tests are not as robust as others and may not be reflective of the environment in which a product is used.

Waterproof, water resistant and breathable.

Waterproof can be defined as an objects’ capacity to be impervious – water won’t get in.

Water resistant means water isn’t going to get in easily.

Breathable

An often used but nonsense adjective. Membranes cannot breathe. Nor can wine. We can.

A ‘breathable’ membrane (or breather membrane) is water resistant and air permeable. The majority of air permeable products will have a high moisture/vapour transmission rate but will not breathe.

Check if a product is waterproof and breathable – many are!!

TAS – Thatch Firewall Membrane

Manufactured in the UK.

Looks and feels similar to a PU28 type membrane but with a far superior coating – a temperature resistant aluminised polymer system.

Tested beneath a combustible material - thatch - to meet both BS476-3:2004 & BS EN 13501-5:2005.

Designated as Broof (t4) – the highest performance in accordance within the European class – BS EN 13501-5:2005, which refers to four separate tests. The suffix (t4) indicates that Test 4 is to be used for the purposes of Approved Document B (Fire Safety) B4 External fire Spread.

Water resistant and tested for air and water vapour permeability.

Tested to meet the same smoke and fire toxicity specification for commercial aircraft.

These are just a few of the tests TAS – Thatch Firewall Membrane carries. When considering a PU28 type fire barrier for use beneath thatch, it would be worth asking a few more pertinent questions.

For further details and information about TAS – Thatch Firewall Membrane, please call the office.

New Meeting room at Thatchers Cider

Thatching Advisory Services - Thatchers Cider

A new meeting room currently being built at Thatchers Cider has been designed to showcase sustainable construction techniques. With that in mind, the Sandford cider maker asked Somerset master thatchers, Dunbar & Bunce to install a new thatched roof.

Passionate about conservation, both Tom and Nigel – together with their team of highly skilled thatchers, provide an extremely knowledgeable and sympathetic approach to both historic buildings as well as modern applications, such as new houses and extensions.

It is being built with a solid oak framework and natural stone walls. Prior to the actual thatching,  the roof  timbers were covered with Thatch Firewall Membrane, which is one of the fire barriers provided by Thatching Advisory Services.

Martin Thatcher, Managing Director says, “Our new meeting room is being built in the heart of a beautiful part of one of our orchards, in a thicket, overlooking a pond. It is an opportunity for us to show how we embrace nature. Beinyears.”

TAS Thatch Fire Membrane System used on unique thatched building in Merseyside

The Lighthouse

Thatching Advisory Services (TAS) were recently involved in an unusual but unique thatched project in Liverpool.

The Lighthouse in Formby saw the majority of the building, including the sides being completely thatched.

The project saw TAS working closely with the main contractor – Kirklake Developments and D-K Architects to advise on and provide the most suitable and comprehensive fire barrier system for the building.

After consultation and submission of test reports, it was deemed that the newly designed and tested ‘TAS Thatch Fire Membrane System’ would be the most suitable system to use for the project.

The TAS Thatch Fire Membrane System, which incorporates Thatch Firewall Membrane and Thatchbatts®  is tested to BS476: Part 3: 2004 and CEN/TS 1187:2012, test 4, as recommended by Building Control – Approved Document B.

Thatching Advisory Services presentation to Cheshire Fire and Rescue Service

Cheshire Fire & Rescue Service

Rob Norcott, Director of Thatching Advisory Services, recently gave a joint presentation with HETAS to Cheshire Fire and Rescue Service about the importance of fire safety for thatch roofs.

The presentation, attended by representatives from Cheshire Fire and Rescue Service and the North West regional office of the NFU Mutual, focussed on the common causes of thatch roof fires and the preventative measures and products available.

The attendees were made aware of the issues and contributing factors for thatch fires and the solutions, products and preventative measures available to help reduce the risk in the event of a fire.

The presentation included the use of comprehensive Thatch Fire Protection Systems which are a mix of either TAS100 Thatch Fireboards or Thatch Firewall with our non-combustible Thatchbatt® product.

Rob was also able to explain how the fire retardant spray ‘Thatchsayf’ works by foaming (intumesce) and forming a carbonised char, which binds the thatch stems together, cutting off the supply of oxygen to the fire, delaying the spread of flame and lowering the radiated heat output.

HETAS are the official body recognised by Government to approve biomass and solid fuel domestic heating appliances, fuels and services.

Thatchbatt® Installation – new recommendation in addition to friction fitting.

Thatching Advisory Services have update their Installation instructions for Thatchbatts®

Since the release of the 100mm Thatchbatt® with its increased fire protection and thermal values, we have seen most architects selecting this over the traditional 50mm Thatchbatt®. Both 50mm and 100mm Thatchbatts® are designed to be friction fitted between rafters set at 400mm centres. Although the 100mm slabs, in most cases, are self supporting we still recommend that the consideration be given to the following one of the wired fixing systems as detailed on our website.

Thatchbatts®
 
 
 
 
 

 

 

 Click the following link to our Thatchbatt® page (pdf  links located at bottom of page).

www.thatchingadvisoryservices.co.uk/Thatch_Batts.asp

Although Thatchbatts® offer increased fire protection, where permitting they should be used in conjunction with either Thatch Firewall or Thatch Fireboard to create a comprehensive fire barrier system. For further thatch advice please go to our website.
