Insulate more thanks to the new WF-7 size

The new WF-7 size is the slim little brother of the classic waal size 50. The measurements are approximately 210 x 70 x 50 mm. This means the WF-7 is 3 cm narrower than the standard size, which offers many benefits in the area of insulation, optimum space efficiency, ecology and renovation options.


-3 cm additional space for insulation
-3 cm more potential living space
-interesting renovation options: 3 cm less protrusion is a relevant difference on your building permit.

Choosing the WF-7 size is also a more ecological choice. Fewer raw materials are required and there is also less energy loss during production. The new size takes up less space during transport and is also a lot lighter in weight. This means lower transport costs.

Tips for laying WF-7 size bricks

- Always use high-quality mortar with sufficient adhesion. The mortar bed is narrower.
- Provide sufficient wall anchors to securely connect the inner and outer leaf.
- For some bonds such as a stretcher bond, you need to cut the bricks to size. The narrower heads can cause a change in the head-stretcher face ratio.
- For standard joints, do not scrape away any more of the excess mortar than strictly necessary.
- Adjust lintels, wall supports, profiles, reinforcement ... in the width because of the slimmer size.
