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.

Thatching Advisory Services (TAS) recently launched it’s new website. The new site contains the latest information on fire protection as well as comprehensive advice on buying, owning and maintaining thatched properties. There is a new section devoted to new builds and extensions which includes detailed information on roof construction and the latest building regulations.
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, whilst taking advantage of the recent warm weather, continued their busy schedule of treating thatched roofs with Thatchsayf fire retardant with a comprehensive application carried out to the roof of the Thatched Cottage in Shedfield, Hampshire.
The 220m² roof was treated with clear Thatchsayf.
For further details about Thatchsayf fire retardant, please give us a call on 08455 204060.
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.
Good advice for your thatched property.
During recent times we have seen an increase in the number of calls from people who are in the process of purchasing a thatched property and are looking for more detailed advice; covering areas such as chimneys, electrical systems, insurance providers, and much more to include the names of local thatchers.
In light of the increased requirement in the industry for more advice, we have updated our safety advice leaflet. The new leaflet gives guidance on areas such as chimneys, wood burning stoves, electrical systems, detectors & alarms and fire barriers.
Over the coming weeks we will be supplying thatcher’s with copies of the leaflets so that if required, they can hand out these to home owners.
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.
For more information about Thatchbatts® or other Thatch Fire Barriers, please contact Thatching Advisory Services on 08455 20 40 60.
Our system was chosen to be included in the Listed Heritage Shopping section of The Listed Property Owners Club Magazine.
Listed Heritage Magazine is a high quality magazine which is distributed to 19,000 listed property club members.
The Thatch Alert Chimney Monitor System has been specifically designed to monitor the temperature of the chimney brickwork at the point where it meets the thatch. The system acts as an early warning device to inform the home owner of potential high temperatures.
