Fixit 222 Aerogel high-performance insulating plaster

The mineral Fixit 222 Aerogel high-performance insulating plaster is the most significant innovation in building insulation in recent years. Thanks to the addition of Aerogel granules, it has a thermal conductivity of just 0.028 W/mK. This is two to three times better insulation than conventional thermal insulation plasters can achieve. Renovation with the mineral Fixit Aerogel insulating plaster system can reduce heating costs by up to two thirds, even with a thin layer thickness of four to six centimetres.

Advantages of Fixit 222 Aerogel:

High thermal insulation performance even with very thin layers: Lambda value of 0.028 W/mK
Condensate-insulating interior insulation
Non-flammable
Regulates the vapour pressure very well during diffusion behaviour
Very high capillary absorbency

The innovative Fixit 222 Aerogel high-performance insulating plaster is bound with lime and is therefore capillary-active and permeable. Thanks to the spraying process, all cavities are filled easily and safely when applying the insulating plaster.

The innovative technology in the Fixit 222 Aerogel product

The use of the silicate Aerogel aggregate – which was originally first used in space travel as a lightweight and particularly efficient insulating material – achieves at least twice the insulating effect of conventional insulating plaster (with the same layer thickness).

Fixit 222 Aerogel high-performance insulating plaster consists of a mineral binder and silicate Aerogel and is unique on the market. The silicate Aerogel, on the other hand, consists of only 5% silicate with a 95% proportion of fine air bubbles trapped in the material. These ensure an efficient insulating effect with minimum space requirements.

Use of Fixit 222 aerogel insulating plaster in renovation and new construction

Fixit 222 Aerogel high-performance insulating plaster can be used almost anywhere: indoors and outdoors as well as in renovation and new-build projects. In new builds, the combination with monolithic single-stone masonry is interesting: when using Fixit 222 Aerogel high-performance insulating plaster, thinner masonry can be planned from the start of the project, thereby increasing the effective living space – and of course without impairing the overall insulating effect of the building.

The mineral plaster is permeable, particularly light with a dry bulk density of 220 kg/m³ and the thermal conductivity coefficient λ_D is 0.028 W/mK. Layer thicknesses of three to eight centimetres can be created per work step. Unfortunately, it is not possible to install ceramic tiles on this plaster. If a heavy covering is to be used on thermal insulation, we recommend using the Fixit StoneEtics® system.

Physical building properties of Fixit 222 Aerogel:

Fixit 222 Aerogel high-performance insulating plaster is both permeable and water-repellent. It can absorb significantly more water vapour than conventional finishing plaster without the insulating plaster itself becoming wet. This prevents water condensation on the surface and the associated mould formation. The risk of micro-organisms colonising the façade is also reduced, thanks in part to the mineral composition of the render.

The low water absorption and hydrophobic properties of the aerogel ensure the long-term insulating performance of Fixit 222 Aerogel high-performance insulating plaster.

Vapour diffusion of Fixit 222 Aerogel

The vapour diffusion experiment in the video shows how air from a small hand pump is forced through the Fixit 222 Aerogel insulating plaster layer into a glass of water. The gently bubbling air bubbles visually demonstrate how vapour-permeable the high-performance insulating plaster is.

Fire protection from Fixit 222 Aerogel high-performance insulating plaster

Thanks to the use of mineral binders such as hydraulic lime and silicate aerogel as a lightweight aggregate, the insulating plaster is non-combustible (fire rating 6q3 according to VKF or fire class A2-s1-d0 according to EN 13501). This means that environmentally hazardous flame retardants are not required.

The fire behaviour test in the video shows the reaction of the Fixit 222 Aerogel insulating plaster layer to a yellow and a blue flame after 4 minutes in each case – recorded in time-lapse.

Long-term measurement in Winterthur

The hygrothermal behaviour was not yet known at the beginning, so a renovation with long-term monitoring and corresponding sensors was carried out in Winterthur from 2012 to 2016.

Cladding with Fixit 222 Aerogel high-performance insulating plaster

The innovative Fixit 222 Aerogel high-performance insulating plaster is a simple way of cladding existing façade thermal insulation.

Thanks to its simple spray application, it can be applied quickly and safely to the existing exterior façade and, thanks to its high insulation value, is extremely effective with a layer thickness of just 4 to 6 centimetres.

Advantages of cladding with Fixit 222 Aerogel high-performance insulating plaster:

No dowel or slab markings

When using the high-performance insulating plaster, you can be sure that no marks will appear on the plugs or insulation board joints, even after years of use. A homogeneous layer of insulating plaster is applied and the keying or shrinkage that occurs with insulation boards cannot occur. No additional dowels are required when cladding with insulating plaster, which could then become visible.

No cavities between the insulation layers

As conventional insulation boards have to be bonded to the entire surface of the façade, the formation of cavities within the façade cannot be ruled out. When the high-performance insulating plaster is applied by spraying, all cavities are filled – no new cavities are created between the existing and the new insulation layer.

No increased growth of microorganisms

Thanks to the higher weight and good diffusion properties of Fixit 222 Aerogel high-performance insulating plaster, less condensation forms on the façade surface or it is better absorbed by the plaster and released again at a later date. This makes it more difficult for microorganisms to colonise the façade.
