Window solutions for professional building projects 

Windows play an integral role in the building envelope. They connect interior and exterior spaces, influence energy performance, and define the architectural expression of a facade. At a:gain, we develop window systems designed for professional building projects that demand verified performance, transparent documentation, and reliable delivery. Our window system, Viddø, combines high material quality with a documented lower environmental impact. The window elements are produced from glass that has been discarded due to minor visual variations yet maintains full technical performance. This approach results in a verified CO₂ reduction compared to windows solutions made with virgin glass. 

a:gain’s Window Solutions Are:

  • Developed as documented building products with verified EPDs 


  • Designed for facade installation 


  • Manufactured in collaboration with established Danish partners 


The focus is on consistent performance, architectural precision, and compatibility with standard building processes. 

Why Choose Window Systems

Viddø offers a reliable and well-documented window solution for projects that value both quality and material responsibility. Using discarded glass as a resource allows for significant CO₂ savings without compromising transparency, strength, or durability.
