PAREX.IT : a French project to develop a coating with aerogel

National financing through the Inter-ministerial Single Fund (FUI)

The project was financed by the 10th Call for Projects from the FUI and has joint backing from the Tenerrdis, Capenergies and Axelera competitivity clusters. Through this project, ENERSENS and its partners have developed an outdoor thermal insulation coating applicable using standard machines that is breathable, fire-resistant and provides better insulation than the best expanded polystyrenes. This solution is simple for facade specialists to implement and avoids complexity and defects connected to cutting or dowelling the insulation. The coating adapts to the building’s contour and its thickness can be adapted to the need. The coating is aimed at three markets:
The renovation of old buildings, in particular in the absence of crawl spaces or when the walls have damp-proof courses;New single-wall brick constructions, for which it provides external mineral insulating cladding that is breathable and outside the thermal bridges. No insulation indoors is then needed;New or recent constructions insulated on the inside and made of concrete or brick, for which it provides significantly more insulation.

HOMESKIN : an European project to develop aerogel panels for internal thermal insulation or external thermal insulation [www.homeskin.net]

European financing through the Horizon 2020 programme

HOMESKIN : The Advanced Aerogel-Based Composite (AABC) materials are a unique new class of materials. The HOMESKIN project aims at developing a new silica Advanced Aerogel-Based Composite material possessing the lowest thermal conductivity of all insulation materials found in the market.

Homeskin is one of the very first projects from the new European Union Research & Innovation programmes. It was selected to be one of the Horizon 2020 program of EeB-01-2014: Materials for building envelope.

The Homeskin project implemented by ENERSENS and its partners has an overall budget of €6.3 million and financing from Horizon 2020, the research and programme of the European Union, under the terms of financing agreement n° 636709, to an amount of €4.5 million. Its goal is to develop insulation systems for outdoor and indoor facades, walls and roofing, while enabling the optimisation of manufacturing techniques for this type of material. In addition, Homeskin provides valuable contributions to standards and regulations for very high performance insulation materials.

Homeskin is contributing to the market launch of revolutionary technology that offers the following benefits:

a reduction of at least 30% of grey energy (used for manufacturing) and CO2 emissions from the components;an improvement by at least 20% of insulation properties;a reduction of at least 15% in total costs compared to equivalent existing solutions;a reduction of at least 5% of the energy consumed throughout a building’s life cycle.

The proposed solution will bring to the market new insulation technologies that do not only possess very high thermal insulation performance but also are thinner, lighter, non flammable, and with lower CO2 and VOC emissions. The new material developed can be applied to new buildings as well as for old buildings retrofit applications.

Among our objectives in this project are to develop more sustainable construction with lower embodied energy, and develop healthy, fire resistant and moisture controlled insulating layers, as well as eco-innovative binders and adhesives, to enhance the durability and reduce maintenance costs, and to demonstrate the energy and health efficiency of building envelopes based on such new materials. The HOMESKIN project shall bring key contributions to the very high performance insulation standards and policies.

Different tasks will be carried out by the partners involved. One part of the work is dedicated to the material development. This material will become the basis for the development of the insulation systems. Coatings and interface materials will be developed according to the AABC integration in the insulation systems solutions (for inside, outside, singular points and thermal bridges insulation applications). These advanced insulating systems will be assessed to validate their acoustical, thermal, hygrothermal, fire safety, and VOC emissions properties. A life cycle analysis will also be performed. The performances of these solutions will then be tested on buildings under real weather conditions, from Passys cells to houses in different European regions and finally to a public authority infrastructure.

High performance insulation developed in the HOMESKIN project will have the following advantages:

Reduction in thickness of insulation

3 times higher efficient than standard insulation products

Breathable product inducing excellent indoor air quality

Suitable for old and new buildings

External and internal applications

Eco-friendly products and systemsImproved durability and sustainability

Easy to transport to site and set-up

WALL-IN-ONE: an European project mixing aerogel with plaster to increase surface temperature and decrease radiative walls emission

WALL-IN-ONE: WALL Insulation NOvel Nanomaterials Efficient systems

H2020 Project ID: 723574

Call Topic: EEB-01-2016 – Highly efficient insulation materials with improved properties 

Duration: From 2016-10-01 to 2019-09-30, ongoing project

WALL IN ONE will develop a consistent package of new advanced sustainable insulation products and systems. The HONEST (High performance Optimized Nanomaterial Energy efficient SysTem) package is a “modular toolbox system” providing a set of complementary solutions that will address most of the complex challenges raised by thermal renovation as well as new construction. The HONEST package includes: insulating thermal coating-finishing with low emissivity, internal high performance insulating plaster, insulating interior patching filler, external high performance insulating render, and insulation clay bricks. These products/systems will provide top insulation performance as well as improved comfort, indoor air quality, fire safety, durability and sustainability.

These highly efficient products are achieved through the synergy between the different members of the consortium through combining the high performance, sustainable, and advanced nanotechnology of the silica aerogel, with existing, already approved, efficient products. The aerogel materials structure properties and cost will be optimised. The process of the five high efficient mineral insulation systems will be scaled-up to test replicability, processability and reach industrial scale. Then, these five systems will be fully characterised including an LCA assessment, along with certification and standardization activities.

In addition, the project sets a major focus on the “go to market” validation of the five products. Business planning and a field market test will be carried out, along with performance assessments on real buildings, and training and communication tools design, in order to maximize use potentials and foster a wide replication throughout EuropeT
he products from the WALL IN ONE project are key enablers to energy and CO2 emissions savings at European level. They will strengthen the industrial leadership and competitiveness of Europe in the construction sector on a global level.
