The depth of RFG placed is dependent on the U Value
required. The RFG is then compacted to this agreed level
to form a stable base. Laying the correct amount of RFG is
critical to allow for the exact level of the final floor finish.
And who needs to move heavy furniture and fittings
about when it can be suspended from above then
dropped, or maybe eased, back into position!
As Jude is also looking for warmth in the Castle, an
underfloor heating system has been incorporated into
their limecrete floor. On top of the glass was laid another
layer of geotextile membrane then a plastic geogrid on
which to clip the underfloor heating pipework.
Finally, the limecrete screed. This is made of a strong
natural hydraulic lime (NHL5) mixed with sand. It can
be mixed in small quantities in a pan mixer but here it
was produced in The Limecrete Company’s volumetric
lorries, to exact quantity and to a completely consistent
specification barrowful after barrowful, and there were
many! The limecrete was then levelled by their skilled,
experienced screeders. After 28 days this floor will be
ready for the final stone floor surface, if it is to be carpets
or wood, more time will be required for it to cure.
Jude chose The Limecrete Company with their wealth
of experience in heritage buildings having been
recommended by their suppliers, Ty Mawr in Brecon.
Jude is particularly delighted with the flooring skilfully laid
by The Limecrete Company, a large step on such a huge
project to restore Penllyn Castle back to its former glory.
