For over a decade now, Ty-Mawr have been researching and developing this insulated limecrete flooring system to be able to offer you the best materials from both a technical and environmental point of view and excellent advice and support. Our team are able to design a floor to meet the needs of your specific building, ensuring that you get the best performance for your building and as well as meet building regulations if required.
Our floor system has LABC Registered Detal and can therefore be used in all 376 local authority areas across the country.
GLAPOR Recycled Foamed Glass gravel is a superior loosefill insulating aggregate ideal for use in our LABC accredited limecrete flooring system.
Our flooring system does not include a moisture impermeable barrier (Damp Proof Membrane). The control of ingress of moisture is achieved by using a layer of recycled foamed glass aggregate beneath the slab material. This material carries CE certification (0992-C13.10.010) and its non capillary active closed cell structure provides the moisture protection for your floor while remaining vapour open.
This material also has an excellent thermal resistance capability. We calculate the thickness of this layer to provide a specified U Value, taking into account the length/thickness of
perimeter walls, overall floor area etc - see Accredited Floor Calculation Form.
The Leca® LWA expanded clay lightweight aggregate is an alternative component to the recycled foamed glass for the insulation layer .
It has been used for many years for this application and is still popular as it is an economic alternative to the recycled foamed glass.
The lightweight aggregate is blended with hydraulic lime to make the limecrete slab.
The slab is laid on the insulation layer...
From the birth of our innovative Limecrete flooring system, launched in 1998 as a breathable, lightweight alternative to cement-based concrete, we at Ty-Mawr have been selecting and testing various materials and combinations of materials to both simplify the installation process and improve the ‘green’ credentials of our floors.
Following developments in the manufacturing process of the GLAPOR Foamed Glass gravel and extensive testing of our recycled lime screed product we are proud to announce the launch of our first breathable, sustainable floor system designed specifically for use with underfloor heating ‘Sublime®’
