High end material for modern buildings


Development of innovative lightweight and highly insulating energy efficient components and associated enabling materials for cost-effective retrofitting and new construction of curtain wall facades.

The European Commission has identified building sector as one of the key sectors to achieve 2020 strategy of the EU. The goal of the 2020 strategy is to create conditions for smart, sustainable and inclusive growth. In regards to the building sector, the emphasis has been placed on two key principles – the principle of ‘nearly zero-energy building’ and the principle of ‘cost optimality’. Moreover, European legislators decided that by 31 December 2020, member states must ensure that all new buildings are nearly zero-energy buildings and by 31 December 2018, all new buildings occupied and owned by public authorities must be nearly zero-energy buildings. The developers, bearing in mind these regulations, realized that the building industry in general, and insulation sector in particular, need a game changer.

Curtain walls, i.e. facade modules, which span from floor to ceiling consisting mainly of transparent glass-walled component, have been an integral part of commercial and public building for over a century. Today curtain walls are associated with modern architecture and their popularity is exponentially increasing. However, curtain walls are often criticized for their limited insulation characteristics. For this reason, the developers of Eensulate technology came up with a product, which will reduce unwanted energy losses.

Furthermore, existing buildings, including historical ones, are responsible for up to 60% of energy losses through the envelope. Eensulate modules are suitable for both new and existing buildings and therefore have the capacity to solve the major energy losses through retrofitting of old buildings.

The goal of the project is to develop an affordable advanced architectural glass to address thermal and acoustic insulation. Eensulate is expected to minimize thermal bridges between curtain walls and sub-structures, have cost-effective control of solar radiation and approach to insulate the spandrel, allow for an easy implementation on site by reducing the weight of the curtain wall.



EENSULATE project aims to develop innovative lightweight (35% weight reduction compared to the current best performing modules).



Due to the variable ratio between the spandrel and vision glass,Eensulate will match any existing façade design (where there are no constraints on original architecture) as well as new buildings.


Targets & Objectives

Characterize and understand how the Eensulate Basic and Premium components work in real conditions considering the dynamic and thermos-tuneable characteristics.


Demo versions

The performances of the Eensulate insulating solution will be assessed at full scale prototype.

30.01.2018 |FENIX TNT team presented the EENSULATE project at BUDMA Fair in Poznan, Poland

BUDMA is the largest construction fair in Poland and Central and Eastern Europe with more than 800 exhibitors from all over the world. It´s a unique opportunity to introduce new products to wide public and a rich source of latest market information. The EENSULATE was presented by FENIX via stand, roll-up, and brochures. The fair took place in Poznan, Poland 30.1.-2.2.2018.
