Diathonite Thermactive

Diathonite Thermactive .037 is a lime-based insulating plaster made from Hydrated lime, NHL 5 binder, Expanded Amorphous Silica, Pumice, Perlite, Cork and Diatomaceous earth. Used internally on solid masonry walls and ceilings, it is highly breathable and helps walls in older buildings dry out thanks to its capillary active nature.

Description

Diathonite Thermactive .037 is a lime-based insulating plaster made from Hydrated lime, NHL 5 binder, Expanded Amorphous Silica, Pumice, Perlite, Cork and Diatomaceous earth. Used internally on solid masonry walls and ceilings, it is highly breathable and helps walls in older buildings dry out thanks to its capillary active nature. Diathonite Thermactive is compatible with a range of substrates, but is mostly applied to solid stone or brick (once any gypsum plaster has been removed) and provides significant thermal improvement to these walls.

Where to use it

Diathonite Thermactive can be used internally on any solid stone or masonry wall and is an ideal solution for the restoration and thermal insulation of older or historic/listed buildings.

Any existing gypsum plaster on the internal side of the wall should be removed first to reveal the stone or masonry underneath.   This ensures the wall will be fully breathable and allows the Diathonite to work to its full potential.  It also provides a reliable key for maximum adhesion of the Diathonite to the wall.

What it does

Diathonite Thermactive is an insulating plaster that can help regulate moisture to manage humidity and damp in solid walls; especially within older buildings. It provides excellent thermal insulation in colder months and helps protect from overheating when temperatures rise outside. A more comfortable indoor climate can be achieved all year round and the energy demand for heating and cooling can be reduced.

In a typical installation, application of 40-60mm of Diathonite Thermactive would improve the thermal performance of the wall by 3.5-4.5 times. This thickness is the most cost-effective way to provide a significant thermal improvement to the wall.

The clever combination of natural ingredients provides mechanical strength and elasticity to reduce the risk of micro-cracking and gives a long-lasting durable finish.
