Inva-Heat castellated matting panels


This week we are taking a look at the Inva-Heat castellated matting panels, an innovative product to the market.


So what exactly are they?

InvaHeat’s castellated matting panels are interlocking vacuum formed sheets
of recycled plastic which incorporate pipe-locating castles. Sheets are laid
over the sub floor, thermally insulated in accordance with Building
Regulations, overlapping the edges by 75mm and interlocking them to form a
continuous layer. Castellated sheets are useful where there is a restricted
floor depth. 16mm pipework is clipped into the panels and the installation
is complete and ready for the specified screed to be laid.

track and rail fixing and/or clips.

How do you install InvaHeat castellated matting?

Each insulated floor panel has interlocking edges on all four sides. The
panels connect together until the entire floor surface has been covered.
