Newton Diathonite is a premixed plaster, bre-reinforced with cork (granular 0-3 mm), clay powders and

NHL 3.5 natural hydraulic lime. The resulting natural compound produces a plaster with

unrivalled thermal and acoustic properties that is both hard wearing and exible

which is ideal for both internal and external applications. Diathonite, when

applied either internally or externally, creates a seamless thermal barrier

which eliminates any risk of cold bridging within the structure.

Newton Diathonite Insulation Plaster

Eco thermal plaster with insulation and acoustic properties

Diathonite is composed of plaster,

bre-reinforced with cork, clay

powders and NHL 3.5 natural hydraulic lime.

With less than 2% inorganic material,

Diathonite is the highest functioning

eco-friendly insulation plaster available.

Diathonite was a medal winner within the

Best Eco Product category at EcoBuild 2011

Thermal Insulation

Exceptional thermal insulation properties.When applied internally or externally,

Diathonite creates a seamless thermal

barrier which eliminates any risk of cold

bridging within the structure.

Thermal conductivity is 0.045 W/mK

Impressive acoustic characteristics

- over twice the performance of

conventional plasters or renders.

The internal application of

Diathonite to party walls

signicantly reduces soundtransference between properties

Sound absorption between

600 & 1500 Hz is >70%

Breathability

Newton Diathonite is very vapour permeable.

The naturally occurring vapour drive continues

unabated so that internally derived humidity continues

to be removed from the internal habitable areas.

The combination of lower internal humidity levels with

higher internal wall surface temperatures ensures

that the dew point temperature cannot be arrived at,

completely removing the risk of condensation and

surface mould.

Vapour permeability = 0.7kg/m2 /hr

TypicalApplications

Can be applied both

internally or externally

As a high performance

insulated plaster for both the

inside and outside of

external walls

As a render/plaster for listed

buildings due to its ‘green’

credentials

As an insulated render nish

for timber frame or SIPPS

structures

Can be applied directly to

Newton System 800 Damp

Proong and Newton System

500 Cavity Drain meshed

waterproong membranes

As a sound insulating plaster

for both external and

internal walls

Thicker application can be

applied to specically prevent

thermal bridges

One of the big advantages of applying Newton Diathonite to existing properties is that the application can be

split between internal and external application, whereas conventional insulation can only be added to the

inside of the walls and so impacts greatly on the internal space. It is usual for the internally applied insulation

to then have a covering, such as plasterboard, which further reduces habitable space.

By splitting the application of Diathonite between the inside and outside of the wall, similar insulation

characteristics can be achieved with just half the space loss of conventional insulation.

Internal and External Application

Quick and easy to apply by hand or spray

Diathonite can be applied externally with a spray machine, allowing for very fast application, or with a trowel for

internal walls. In addition, Diathonite can be applied directly to Newton System 800 Damp Proong and Newton

System 500 Cavity Drain meshed waterproong membranes. For a recommended installer or specialist spray

company in your area, please contact John Newton & Company.

Application of Diathonite to internal walls of an old stone

cottage in Cornwall

The cottage now benets from the high thermal properties

of Diathonite, so keeps an even temperature all year round

Diathonite can be applied directly to Newton Damp Proong

and Cavity Drain Waterproong meshed membranes

Diathonite can be applied externally very quickly using

a specialist spray machine
