Thatch Fire Barriers – LABC Registered

Thatching Advisory Services (TAS) have two proven thatch fire barrier systems: Thatch Fireboard System and Thatch Firewall Membrane System - both systems are approved and listed on the Local Authority Building Control (LABC) Registered Details database. LABC registration is a one-off certification process proving compliance with building regulations and standards across the UK.

The registered details database contains various products and systems, which once certified, are accepted by LABC building control surveyors in over 300 local authorities across the country. This assures the whole construction industry that a product or system has been rigorously checked by LABC surveyors.

Full details on both systems can be viewed via the LABC links below:

Thatched new builds in Somerset

Bovis Homes

The first of two new thatched properties in the South West are almost complete.

Bovis Homes included the properties as part of a development near Wookey Hole in Wells Somerset.

The first was thatched by Nigel Bunce of Dunbar & Bunce Master Thatchers.

The 130m² roof has a tiled ridge which is often seen on many thatched roofs in Holland.

Prior to the thatching the roof timbers had TAS100 calcium silicate thatch fireboards fitted and 50mm Thatchbatts® installed between the rafters.

The second property is expected to start early in the New Year.

TAS recently carried out the application of its Thatchsayf fire retardant to a lovely thatched new build in East Hendred, Oxford.

The 350m² (38sq) roof was thatched by Fowler and Sons Master Thatchers Ltd.

Prior to the thatching, the roof timbers were covered with 9mm calcium silicate TAS100 Thatch Fireboards and 200mm Thatchbatts® will be fitted between the rafters on the underside of the fireboards. The Thatch Fireboard System meets the Dorset Model and has LABC approval.

The Farmers Arms – Thatchsayf Fire Retardant

IMG_2268

TAS recently completed the application of Thatchsayf Fire Retardant to the Farmers Arms in Combe Florey, Somerset.

The pub was completely gutted by fire in January 2017 and it is believed that an ejected ember or spark was the cause. The roof is around 250m² and was thatched by Richard Pascoe and his team.

Prior to thatching, the roof timbers had TAS100 Thatch Fireboards fitted and 100mm Thatchbatts® installed between the rafters. The refurbishment was carried out by Les Joint Building Contractors.

The pub is due to re-open later this year.

Roundhouse – Thatchsayf Fire Retardant

Thatched Roundhouse

TAS recently treated this thatched roundhouse at Parluant Park Primary School in Slough, Berkshire with Thatchsayf Fire Retardant.

The roundhouse was thatched by Anthony Brown of Conygar Coppice. During construction, the students learnt about thatching from Anthony and helped daub the walls.

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.

Cracking thatched retreat

IMG_0074

Continuing with their busy programme of thatched roof fire protection, TAS recently applied its Thatchsayf Fire Retardant Spray System to the thatched roof of a cracking garden retreat in Bedford.

The retreat was built and thatched by Harry Roberts who is based in Bedford.

We have a number of unusual (and more conventional) projects coming up shortly – provided the summer behaves!

Keep an eye out on the blog for details. If you have any questions about our fire retardant spray system or would like an ‘affordable’ quote & ‘professional service’ or require general thatch advice please contact us.
