Pick the wrong density and you're plastering every wall twice to compensate. UDK is built around avoiding that mistake.

UDK is a Ukrainian brand focused on aerated concrete blocks - the material that's taken over residential construction across Eastern Europe for good reason. Lighter than brick, easy to cut on-site, and faster to lay. A skilled team can put up walls noticeably quicker than with traditional masonry.

At Colorista in Chisinau you'll find a practical selection from the UDK range - sized for interior partitions and lightweight residential walls. Not a warehouse catalogue, but what's here ships from local stock.

A few things worth knowing. Use thin-bed adhesive mortar (1-3 mm joint), not standard cement mortar. Thick joints cancel out the thermal performance of the block. And if you're building exterior walls - always add a protective finish. Moldova's freeze-thaw winters are hard on exposed aerated concrete.

Brand origin: Ukraine.

D400-D500 works well for partition walls. D300 insulates better but handles less load. For load-bearing walls, go D500 minimum and confirm with your structural engineer.

Yes, but always with a protective system - render or cladding. Exposed aerated concrete absorbs moisture and deteriorates in freeze-thaw cycles. Moldova gets down to -15 in winter.

Specialist thin-bed adhesive for autoclaved aerated concrete - 1-3 mm joint. Standard cement mortar with 10-15 mm joints cuts the block's thermal performance significantly.

Roughly 3-5 times lighter at the same volume. That means less load on foundations and faster work for the crew - one block replaces several bricks in volume.
