  1. Solid wall properties can benefit from underfloor heating

    Leave a Comment

    Tŷ-Mawr Lime, a family firm based in Brecon, were the overall winner in the ‘Best Technical Innovation’ category of the South Wales Building Excellence awards, organised by LABC-Cymru (Local Authority Building Control – Wales), for their Sublime Breathable Flooring System.

    Sublime® floor’s breathability makes it ideal for use within existing solid wall properties.

    The sublime system is specifically designed for floors that will contain underfloor heating. Installing the underfloor heating pipes within a higher density thermally conductive layer eliminates the need for two layers (slab and a screed). As a result, the Sublime® floor offers many significant benefits and savings:

    Reduced overall excavation depths: When compared to a conventional Limecrete systems using a lightweight insulating slab layer plus a higher density screed layer to contain the underfloor heating.

    • Reduced wet trades and processes: As only one wet mixed layer is required over the GLAPOR.
    • Reduced installation costs: In both labour and in the cost of materials when compared to our old system
    • Reduced installation and curing times: By eliminating the need for two layers curing times are reduced by approximately 3 weeks
    • Improved energy efficiency and response times of under floor heating systems: As the insulation material is now directly beneath the heat source the heat drift associated with other systems is significantly reduced
    • Reduced material quantities and therefore reduced delivery costs
    • LABC Registered detail: (Received Feb 2013) Recognised in all 376 local authority areas, the registered detail will help to streamline and simplify the planning application and building control process for your project.

    This presentation will summarise a seven year collaboration between the University of Bath and Bristol based company ModCell Ltd in the development of prefabricated straw bale construction, focussing on two local projects: BaleHaus at the University of Bath and the Nucleus Building at Hayesfield School.

    Straw bale construction offers many potential benefits in the delivery of much needed lower carbon and more energy efficient buildings. The traditional use of straw bales on site, as large building blocks, has proven successful in self build and other smaller projects, but has failed to be accepted by mainstream construction industry. The use of straw bales in prefabricated (factory manufactured) building panels, both for cladding and load bearing walls, offers an innovative solution and that realises benefits and addresses many of the concerns.

    Pete Walker is the BRE Trust Professor and Director of the BRE Centre for Innovative Construction Materials and current Head of Civil Engineering at the University of Bath. His research interests include renewable materials (prefabricated straw bale; hemp-lime), modern earth building, lime mortared masonry and innovative timber engineering.



    Tim Mander has been at the forefront of sustainable design thinking for over twenty years and continues to pioneer some of the most exciting new ideas in the industry. As a Director of Integral Engineering Design, Tim is proactively involved in projects and provides a strong design lead. He firmly believes that good architecture and good engineering go hand in hand and need to be fully integrated to deliver high quality buildings cost effectively.
