Thatching Advisory Services (TAS) have received notification that both their Thatch Fireboard System and Thatch Firewall Membrane System has been approved and added to 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:
Thatching Advisory Services are pleased to announce their involvement in the ‘Future Thatch’ project at the 2017 Ideal Home Show.
The project will see TAS working alongside master thatcher – Paul Wareing (Heart of England Master Thatchers).
The ‘Future Thatch’ project will see a newly built thatched property in the main show village.
Every year, the main stunning feature of the Ideal Home Show is the three fully built show homes where over 250,000 visitors have the opportunity to fully explore and take inspiration from. The last time a thatched house featured in the Ideal Home Show was 1976.
Each show home is built to Building Regulations and like many thatched new builds; the show home will incorporate the TAS Thatch Fireboard System and Thatchsayf Fire Retardant Spray System.
U-Values & Condensation in thatch
Modern living under thatch has changed in the last 10 to 15 years, with the introduction of modern central heating, double/secondary glazing, power showers and more home owners wanting fully vaulted ceilings. In addition, the requirements and associated recommendations from Building Control and insurance companies see the requirement for fire barriers and increased levels of insulation to be installed within the roof structure.
All these areas can have an effect on the performance of thatched buildings, therefore all components of the roof structure need to be built into U-Value calculations/reports.
U-Values are expressed in units of watts per degree of temperature difference W/m²K. Overall U-Values will vary according to actual thickness and density of the thatch. For example:
- 300mm thickness of Water Reed – 0.29 W/m²K
- 300mm thickness of Long Straw – 0.23 W/m²K
For comparison, the standard in Part L of the Building Regulations (2010) for replacement roof insulation at rafter level is 0.18 W/m²K.
A suitable insulation product to help achieve a U-Value of 0.18 would be Thatchbatts® as they are non-combustible, high density slabs which also offer additional protection in terms of fire resistance.
It is widely accepted in the construction industry that in addition to sufficient levels of insulation, vapour control layers are required to control vapour and reduce the risk of condensation. A correctly fitted vapour check will also play an important part in the way the building continues to perform in the long term.
Bespoke U-Value & Condensation Risk Analysis reports can be generated for thatched roofs and will take into account the design and construction, type of materials used and location within the country.

There is comprehensive information on all our products and systems and a new facility to buy the products via our online shop.
Have a look around the site and feel free to contact us with feedback or if you have any further questions or queries.
Thatching Advisory Services recently completed the application of Thatchsayf fire retardant to Stream Cottage in Glynde, East Sussex.
The Grade II listed cottage is one of the oldest in the Glynde parish, dating back to 1556.
Prior to the new thatch, the roof structure also had TAS100 Thatch Fireboards and Thatchbatts® installed.
The 127m² roof was thatched by Gavin MacDonald Master Thatcher
Thatching Advisory Services have been out and about recently treating a number of thatched roofs with their fire retardant – Thatchsayf.
Mid-July saw Gary go off to Portadown in Northern Ireland where Master Thatchers (North) Ltd recently completed a full re-thatch of the roof at Bilbrook Cottage.
The cottage also had TAS100 Thatch Fireboards and Thatchbatts® installed prior to the thatching taking place.
The 230m² roof was treated with clear Thatchsayf.
Thatch is enjoying a resurgence. Architects, builders and owners increasingly acknowledge the advantage of thatch insulation and aesthetic qualities. Recognising this increasing popularity the eight building control authorities throughout the county of Dorset reviewed current building controls for a thatched roof.
The result of these controls will:
- Either protect the main structure of the building if a fire occurs.
- Or provide better protection for the roof members if a fire occurs.
- Require an acceptance to treat the thatch as sacrificial in a fire.
Companies specialising in thatch roof insurance welcome the “Dorset Model” and recognise that it will reduce the premiums paid.
TAS has recently embarked on a campaign to highlight the authenticity of one its products – Thatchbatts® and has sent out information highlighting the levels of testing and approvals that the product has gone through.
In summary, when specifying a non-combustible insulation product for a thatched roof, this needs to been done on a like for like basis and therefore careful consideration should be given to the specification. Thatchbatts® are a vital component of both the TAS-Thatch Firewall & TAS-Fireboard systems.

Thatching Advisory Services will be attending
The National Society Of Master Thatchers Annual Conference and AGM.
Entitled ‘For the Good of Thatch’
Friday 14th to Sunday 16th March 2014
It is to held at The Norfolk Arms Hotel, Arundel in West Sussex.
The agenda will include discussions on: The Thatch Mark Standard, Chimney safety and Fire barriers and insulation.
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.
