ISO-THERM – Thin Internal Wall Insulation (TIWI) 7.5m Roll

A new and innovative patented textile based thermal wall insulation, which creates dry and warm walls. Designed to save energy and keep walls dry supplied in 15m2 rolls (15m long x 1 metre wide) 


 ISO-THERM is an ultra thin (+/-4mm) specially woven polyester based material, which is both unique and patented.

 it is flexible and lightweight and will accommodate a multitude of wall finishes.

Due to its ease of use and flexibility it can be cut around light switches/sockets/radiator brackets and the like, and is minimally invasive in its installation.

Very often , door architraves and skirtings can remain in place, and because of its malleability it fits around and into window reveals with ease.

It is fixed in place with our unique ISO-THERM adhesive, normally trowelled onto the wall to a thickness of circa 5mm, and with the ISO-THERM affixed and rolled into the adhesive, the overall finished depth after a direct plaster skim coat is approximately 10mm. Iso-Them adhesive is available seperately on this site,                                                                      click here –
Note This item is excluded from our free delivery offer due to weight and size.

ISO-THERM is vapour permeable, but waterproof, thereby resisting any lateral damp transference, and stopping the subsequent natural surface nitrates and chlorides forming as an efflorescent salt. Because of its high thermal benefit, and the withholding of any natural damp transference it is highly resistant to any formation of surface mould.
