About Green Glass Factory

We find the best.
You build with it.

Founded in Riga, Latvia, Green Glass Factory was built on one belief: that great buildings deserve great windows and finding them shouldn't be complicated. We partner with the world's leading certified manufacturers so our clients never have to compromise.

We're not a factory. We're the people who know exactly where to go, what to specify, and how to get it to your project without the headaches.

The windows and doors we source are PHI Class A certified, achieving a minimum heat loss of 0.52 W/m²K, among the most rigorous energy performance standards in the world. Every product is specified to your project.

From first conversation to final delivery, we handle specification, procurement, and logistics for clients across Europe and North America.
