The Q-Air project plan consists of six work packages from product-system development finalization                       with technology optimisation, certification, BIM, sustainability characterisation, innovation dissemination and exploitation to project management.

WP 1: Management

The daily management of Q-Air project and its advancement is procured under this work package. Organisational, administrative and communication aspects of the project are assumed by the managerial structure, consisting of Steering Committee, Technical Supervisor, Production Line Supervisor, Innovation Manager, Exploitation and Dissemination Board, all reporting to the Project Coordinator.

WP 2: Q-Air façade system development with improved characteristics and more competitive production cost

With development activities in final stage, we will enhance Q-Air façade system for wider usage by developing profiles for longer spans, large size elements, additional cover material applications, adjusted system for refurbishments and by optimizing production line capacity. We will establish expert knowledge centre.  

WP 3: Testing and certification

Developed Q-Air elements and system in different conditions and for different building requirements will be tested and certified.

WP 4: Development of Building Information Modelling (BIM) process

For architectural, design, production and installation purposes Q-Air BIM library will be developed and tested on specific Demo Case Study. Guidelines and tools for further BIM process integration into industry sector will be prepared.

WP 5: Analytical characterisation and sustainability analysis

Technical properties will be analysed using numerical methods and calculations of environmental impacts for variety of product-system options will be prepared. Impact on the sustainability according to different methods used for building assessments will be elaborated. We will numerically evaluate occupants comfort in the building with Q-Air façade by taking into account key aspects such as thermal, visual and sound comfort, air quality, natural daylighting for different climates (locations) as well as orientation of buildings.

WP 6: Innovation dissemination and exploitation

A comprehensive action plan for the effective dissemination and exploitation of Q-Air project results will be elaborated. We will prepare variety of Q-Air contents and materials for presentation and demonstration purposes to all stakeholders and make publications. For architectural, construction, sustainability and other professionals we will organize educational events, present Q-Air on international conferences and fairs. We will participate on science conferences, submit scientific articles and prepare guidelines for more sustainable glass façade construction. We will also prepare a Call for international competition for architects and young students of architecture from the globe to provide the best architectural and sustainable solution using Q-Air innovative glass façade system.

Q-Air a New Generation of Glass Facades

Q-Air innovative unitised glass curtain wall system represents a new generation of sustainable glass facades and is a unique single skin glass façade that offers all the performance and benefits of an active double skin façade.  Q-Air provides superior energy efficiency, and thermal and visual comfort, whilst maximizing the prevention of excessive solar heat gain and delivering unimpeded visual contact with the environment. Q-Air beneficially contributes to improved well-being and health of people inside the building.

To assure a complete building envelope solution for any building type or application, Q-Air is available in transparent, translucent and opaque unit options supported by either polymer or aluminium extrusion profiles. Q-Air can be used either for new constructions or refurbishments, either for all-glass buildings or buildings incorporating other materials.

Innovative Multi-Chamber Core

Using the science of thermodynamics and advanced structural glazing technology, Q-Air is a game changer for the new future of sustainable architecture, construction and living. Q-Air uses an innovative, multi-chamber insulating core, which delivers exceptional energy efficiency, living and working comfort, ultimate aesthetics and economic benefits.

Q-Air uniforms large, fully structural glazed surfaces. Available as a structural external and internal face without any visible frames, emphasizes an attractive flat architectural solution. Q-Air as a total performance glass curtain wall system doesn’t need any external solar shading devices that are commonly used with conventional facade systems.

Innovation in Action

Q-Air glass facade manages solar heat gain (g value), thermal transmittance (Ucw value) and light transmittance (LT value) so perfectly that a full transparent glazed area (panoramic glazing) is achievable whilst fulfilling the building regulations for thermal insulation and total energy consumption of the building. Q-Air provides superior thermal insulation level Ucw ≥ 0.30 W/m2K for fully transparent glass façade. 


World’s best-performing glass curtain wall system:

  • Exceptional energy efficiency and living comfort:
            Ucw ≥ 0,30 W/m2K
    g = 0,09-0,34
    LT = 0,10-0,56 
  • Larger areas of the facade to be transparent
  • Doesn’t need any external solar shading devices
  • The thinnest glass curtain wall with the highest thermal insulation
  • Increased usable building space
  • Flush internal and external design available
