Diasen Diathonite Evolution

Lime, cork and clay based insulating plaster

Diasen Diathonite Evolution

Main purpose

Insulating the building and maintaining the breathability of the wall/ceiling.

Use it on

Internal or external solid stone or masonry walls and ceilings. Can also be applied to wood-based panels/sheathing and plasterboard that have been primed with Diasen Aquabond Primer. Diasen Thermal Plaster, Diathonite, does not impede the ability of a wall to breathe. This is particularly important when dealing with solid brick or stone walls, which utilise lime mortar and lime plaster systems. Unlike many modern impervious thermal insulation systems, Diathonite thermal insulating plaster, is a breathable insulating plaster which provides the optimum combination of both thermal performance and moisture management.

Overview

Diathonite Evolution is a fully breathable lime-based insulating plaster made from Hydrated lime, NHL 3.5 binder, Clay, Cork and Diatomaceous earth. It is highly breathable and helps walls in older buildings dry out thanks to its capillary active nature. Diathonite Evolution thermal plaster can be used internally or externally on

solid stone or masonry walls and ceilings. It should be applied to exposed stone or brick after any gypsum plaster has been removed. It can also be applied on wood-based panels, lath and plasterboard that have been primed with Diasen Aquabond.

Where to use it

Diathonite Evolution thermal plaster can be used internally or externally and is ideally suited for the restoration and insulation of Historic/Listed buildings or any building with solid stone or masonry walls. Before you start your project, it is essential to investigate and fix any existing damp or moisture related issues in the wall; please see our installation guide for full details. For optimal performance and longevity of any internal wall insulation system, it is crucial to evaluate the suitability of the wall and rectify any problems before installation begins. Please read our guide: “How to prepare traditional solid walls for IWI Installation” to ensure you achieve the best results. Diathonite Evolution is supplied in 18 kg bags. There are 60 bags per pallet.

What it does

Diathonite Evolution is an insulating plaster that can help regulate moisture to manage damp and humidity in solid walls often found within older buildings. Please note, Diathonite Evolution does not cure penetrating damp. Prior to application, any existing damp problems must be fully resolved. In a typical installation, applying 50 - 75mm of Diathonite Evolution will 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 mechanical strength and elasticity are provided by the clever combination of natural ingredients. Elasticity reduces the risk of micro-cracking for a long-lasting durable finish.Diasen Thermal Plaster, Diathonite, does not impede the ability of a wall to breathe.

How it works

The Diathonite system is breathable and capillary active. It lets vapour pass through and actively transports moisture from the structure of the building helping the wall and building dry out. It regulates humidity and prevents condensation and mould growth.

Why we love it

The main ingredients are Hydrated lime, NHL 3.5 binder, Clay, Cork and Diatomaceous earth. These all-natural ingredients are sympathetic to the conservation requirements of listed buildings and will contribute to LEED credits. Evolution dries much faster than a traditional lime plaster; usually it only takes one third of the time which works out at approximately 2mm per day. Unlike dry board systems, Diathonite Evolution is malleable and flexible when being applied. This gives many beautiful aesthetic options for rounded window reveals and curved wall surfaces that follow the contours of the underlying stone or brick, especially in stone cottage refurbishments. A more modern style finish can also be achieved when required. Diathonite Evolution is not only a highly effective stand-alone insulating system but also an ideal levelling coat for uneven walls prior to using breathable insulating board systems like Gutex Thermoroom and Calsitherm. It is non-combustible so will not burn or emit smoke.
