We Source the World's Best Glass Bricks.
Is In Materials is a specialist glass brick supplier based in Lithuania — serving architects, interior designers, and builders across Europe and beyond.
Built by people who care about what goes into a space.
Hello, I'm Indrė, and together with my partner, we founded Is In Materials from a shared conviction: that the materials used in a space define its soul.
We started this business because we kept seeing the same problem — architects and designers with bold visions, struggling to source glass bricks that matched the quality and character their projects deserved. Generic products. Unreliable supply. No real expertise on the other end of the phone.
We wanted to be something different. A supplier who understands design, speaks your language, and takes the same care over material selection that you take over your projects.

Worldwide Sample & Pallet Shipping
Whether you need a single sample pack for a client presentation or a pallet for a pilot installation, we ship worldwide — fast, tracked, and packaged to arrive intact.
Sourced in Asia. Coordinated from Lithuania. Delivered worldwide.
Three things every client tells us they value.
We know glass bricks from the inside out — optical properties, installation tolerances, weight loads, thermal performance. When you call us with a technical question, you get a real answer.
No call centres. No account numbers to remember. You deal directly with the people who run this business, who know your project, and who care whether it succeeds.
From specification support and sample coordination to delivery scheduling and surplus returns — we stay involved through the full project arc, not just the sale.
Let's Work Together.
