Tŷ-Mawr Lime Ltd is a Welsh manufacturer and supplier of traditional and environmentally conscious building materials, specialising in lime-based products, natural insulation and breathable construction systems.
Established in 1995 by Nigel and Joyce Gervis, the business developed from the restoration of their historic farmhouse near Brecon. The difficulty of obtaining suitable traditional materials for the project led to the production of lime mortars and plasters, subsequently developing into a wider manufacturing and distribution operation.
Today, Tŷ-Mawr supplies materials for historic building conservation, traditional property renovation, sustainable retrofit and new construction throughout the United Kingdom.
The company's insulation range includes natural and recycled materials intended for improving thermal performance while maintaining appropriate moisture-management characteristics within building structures.
Principal materials and products include:
Tŷ-Mawr manufactures and distributes lime mortars, plasters, renders and finishes used in the repair and conservation of traditionally constructed buildings.
Its range includes lime putty, natural hydraulic lime, pre-mixed mortars, limewash and specialist lime-based products for historic masonry, pointing, plastering and rendering.
These materials are relevant to buildings constructed using traditional methods, including solid-wall masonry, cob, stone and brick, where compatibility with existing fabric and the movement of moisture are important considerations.
The company supplies integrated building systems intended to support the sensitive thermal improvement of existing properties.
These include:
Among its developed products is the sublime® insulated limecrete floor system, which incorporates recycled foamed-glass aggregate and lime-based construction materials.
The system provides an alternative to conventional concrete floor construction in suitable applications, with particular relevance to traditionally constructed buildings where moisture movement through the floor and adjoining walls requires careful consideration.
Alongside manufacturing and supplying materials, Tŷ-Mawr provides technical assistance to architects, surveyors, conservation specialists, building contractors and property owners.
Its services include material selection advice, mortar and paint analysis, insulation-system guidance, thermal performance calculations and condensation-risk assessments.
The company also operates a training centre at its historic premises in Llangasty, near Brecon, providing practical courses and professional development activities covering traditional lime construction, plastering, limecrete flooring, natural insulation and sustainable building techniques.
Tŷ-Mawr's materials and systems are relevant to:
Selection of appropriate materials and insulation systems should be informed by the condition, construction and significance of the existing building, together with relevant conservation and technical requirements.
