Product Details Company Info More from this company

Thermalime is the insulating lime plaster. It comprises of chalk, a St Astier lime binder, fibres and a naturally formed insulating component. This unique mix provides an element of thermal insulation to the interior or exterior of buildings, without losing the breathability and visual beauty of a soft lime plaster.

Thermalime is sufficiently versatile to use either externally as a render or internally as a plaster.

This unique product benefits from being:

Lightweight – making it ideal for ceilings

Breathable – essential to eliminate the risk of damp

Flexible – meaning it can cope with the natural movement of a building without cracking

Durable – because of its speed of set, it has an added freeze thaw protection over other lime plasters and renders

Quick – it can be applied one day and finished the next

Easy-to-use – simply requires the addition of water before being mixed and applied either by hand or spray applied with Rendergun

Thermalime had a lamda value of 0.1372W/(m.K) (Thermal Conductivity test in accordance with BS EN 12667:2001).

Thermalime allows you to keep the warmth in without compromising the integrity of the building.

The last 25 years have seen the use of building limes develop from what was regarded as a quaint eccentricity to an understanding that they are a central element of building conservation. This understanding led to a realisation that the properties of lime could be utilised very effectively in new-build work.

It also became obvious that building with lime is of key relevance to current environmental concerns.

Since 1993 when Anglia Lime Company pioneered the use of lime in East Anglia through training courses and the distribution of lime materials, this new awareness has brought about an ever-increasing use of lime in both old and new buildings.

In turn, this has led to the development of lime-based products and systems that make the use of lime more efficient and convenient, while retaining the beneficial properties of lime.

Anglia Lime Company can offer a sustainable lime-based solution, whether you are repairing plaster in your 15th Century cottage, re-pointing Georgian brickwork, installing a lime concrete floor or looking for a pre-coloured, spray applied finish for the most modern of buildings.

As well as manufacturing a range of ready mixed mortars and renders, including hair, fibre and insulating mixes, we supply best quality matured lime putty, natural hydraulic limes (NHL), limewash and lime paints, chalk aggregates, wooden laths, tools etc.
