F2TE3 is a new lightweight, slim, high energy efficient, envelope system that provides for seamless, free-form designs for use in arquitectural projects. Its innovative design combines thermal insulation materials (encapsulated transparent monolithic aerogel) with new technologies (vacuum chamber) to provide a vacuum insulation panel  (VIP). The patented solution enables a complete facade system design, both in version transparent area for windows and opaque one for walls.

Model simulations ensure meet both spanish CTE (Technical Building Code) and UNE standards. F2TE3 technical performance provides highly relevant and specific values  in terms of acoustics, energy performance and light transmission.

“Energy savings through the building envelope with a minimum thickness (3,5 cm transparent facade that insulates the same as a 30 cm conventional brick wall) including free-form designs”

• Energy inefficiency of building envelope solutions, particularly, the transparent ones. The challenge of curtain walls is energy saving and solar control to implement 20-20-20 targets by 2020 (reduce by 20% the primary energy consumption in the EU).
• Current challenge of designing curtain wall facades in a more spectacular and visual way.
• Improving the level of occupant satisfaction in buildings (for reference only, 27% higher in users of environmentally certified buildings) [LEED].
• Adapting the living spaces to the current needs of users, both professionally and personally.
• Structures with higher flexibility are required, in particular in geographic areas of greatest seismic hazard.

• The energy efficiency sector accounted for 1,8% of spanish GPD in 2012. From 2005 to 2010, it drove 1.500 M€ just in partnership collaborations. [Ministerio de Economía y Competitividad, Gobierno de España].
• Worldwide, the construction industry worldwide is growing at a rate of 4.4-5.1%, in particular, the glazing area [Business Economics].
• The overall doors and windows market is a global business valued at 60.000 – 94.000 M€, and a approximately 5% growth, half of it focused on windows [Business Economics]. 
• Big companies in the curtain-wall industry account for 76% market, valued at 1.950 M€ at european level [Standard and Poor’s].
• Spain is the second european manufacturer of windows, with an estimated 10% of production.

• 80-91% more insulation than current curtain-wall systems, which implies direct savings between 42-77% (according to the British Fenestration RatingCouncil).
• High degree of light transmission: 89% transparency.
• Maximized solar control: reducing UV transmission up to 0% and IR transmission up to 10%
• “Overlap” system between panels that is able to eliminate thermal bridging and to improve insulation in the union of those ones. This weakness has been detected in 90% of current commercial systems.
• Almost 100% recyclable.
• Soft covering: rigid and strict modules unrestricted.
• High strength: best existing rating according to UNE-EN 1419:2004 standard.

“Improving insulation, energy efficiency and lifetime (5 times higher) than competing solutions, F2TE3 has a lower cost, around 1,4 and 3,7 lower than those ones”
