Hi-tec hi-strength fired clay walls

Ziegel Building Blocks from NBT enable load bearing single skin walls to be made from honeycombed clay blocks.

Ziegel Building Blocks from NBT, combine sophisticated hi-technology with ecologically sound and sustainable practices which can be used to construct single skin, multi-story, buildings that easily exceed the latest regulations.

What's more, the lightweight blocks use a virtually dry construction technique that's fast, cheap, rugged and offers excellent thermal and acoustic performance for both external and internal walls.

The system is approved as a modem method of construction by the Housing Corporation.

It offers robust detailing which eliminates the problems associated with damp cavities, cold bridging and vapour barriers.

Made from fired clay in an intricate honeycombed design, the blocks are both strong and lightweight.

They give a high thermal and acoustic mass to the finished building but have around 40% less embodied energy than conventional structures with the same U value.

They provide overheating protection in summer and can reduce peak internal temperatures by as much as 4C.

The recent Building Regulations (Part L) have made this method of construction particularly suited to the UK.

A 300 mm block will automatically meet current building regulation standards for walls (ie a U Value of 0.35).

Higher performance blocks and systems are also available.

NBT's Zeigel system comes with a wide variety of corners, lintels, blocks for internal pipe work, internal partition blocks and even flooring and roofing systems.

Special mortars are provided, as are mortar laying machines and full technical and design support is provided as standard.
