Product Description

TECHNITHERM is a totally CFC & HCFC FREE two component, 1:1 mix ratio rigid urethane foam which complies with the requirements of BS 7457:1994 for the stabilisation and thermal insulation of masonry cavity walls and holds an Agrément Board Certificate No: 97/3426. It is strongly recommended that TECHNITHERM is installed in accordance with BS 7456:1991 Code of Practice by operators trained by Isothane Ltd technical staff or by BBA approved installers.

Uses

TECHNITHERM is used for the stabilisation of masonry cavity walls by strongly adhering the inner and outer leaves together and as such is a convenient and cost effective alternative to metal cavity tie replacement. In addition, as a consequence of the excellent thermal insulation properties of the foam, “U” values of 0.33 Wm²K are achieved in a 65mm cavity of standard construction, and 0.22 Wm²K in a 100mm cavity of standard construction. Even better values can be realised through choice of special blockwork, etc.

Equipment

TECHNITHERM can be processed through any suitable mobile high pressure plural component urethane foam dispensing equipment. (e.g. Gusmer, Glas-Craft / Probler).
