Project Overview

• Huge potential market for a highly insulating material for new buildings and retrofits that can satisfy the needs of high density housing and new insulation regulations in Europe. 

• This opportunity can be met by new building materials containing aerogels that have very low thermal conductivity (< 0.01 W/(m.K) as a monolith and typically ~ 0.015‐0.018 W/(m.K) in granular form)

Cost‐effective route to a robust aerogel for use as an 

insulation material in buildings

Demonstrators• Demonstrators for all 3 applications at Envipark, Turin

– Demonstrators were set up in Sep‐Oct 2014

– Data collection over winter of 2014‐2015 

– Measurement of thermal resistance of the wall with HIPIN building elements was carried out per ISO 9869:1994 standard

– Protect sensors from direct sunlight for data accuracy

– Data acquisition and analysis showed U value improvement compared to the bare wall

APPLICATION BENEFITS

Suitable for old and new buildings

External and internal application

Space optimization(low thickness)

HIPIN plaster based on HIPIN aerogels

HIPIN aerogel‐based panels• Methodo produces state of the art ventilated façade 

systems formed by a structure supporting the tiles and an insulation layer.

• HIPIN panels allow for reduced thickness of panels, with lowered costs of support structures

• The developed product showed a thermal conductivity (λ = 0.025 W/(m.K)); represents an improvement of ~25% compared to best in market EPS.

• The development of the technology in the HIPIN project predicts a further  reduction in the thermal conductivity could be achieved by refining the fabrication process.

Techno‐economic analysis

Cost of aerogel drives techno‐economic analysis; depending on loading of aerogel in the system.

Estimated cost of aerogel €2.2/liter (density 0.18g/cc) at 250tpa scale. Less than €1/liter possible with demand of > 5000 tpa.

As cost of aerogel comes down with growing demand, economics will be even more favourable. 

Eg: For the plaster, energy savings via insulation benefits (U value achieved with less thickness) complemented by lower material use, which in turn has benefits in lowered cost of application of the plaster and transportation savings.

Mathematical Modeling

• Mathematical models used to determine the reduction in heating energy achievable using the three products

• Theory also used to predict the thermal conductivity of the materials based on knowledge of their composition

• Theory confirms measured values and provides a basis for further product optimisation
