explained…
Concrete blocks are available
in a range of widths.
Concrete blocks are made using a variety of
natural or man-made aggregates.
There are three basic types:
• ultra-lightweight
• lightweight
• dense
All types deliver low cost solutions for homes
and buildings. They also deliver:
•
• good acoustic performance
• durability
• thermal mass that helps keep you cool in
summer and warm in winter.
