ThermoPlan Ziegel Benefits
Fundamentally, ThermoPlan Ziegel is a honeycomb clay building block. It is faster and simpler to build with, will
out perform other masonry systems and yet offers similar built costs. ThermoPlan (known as Ziegel on the continent) is proven
over hundreds of years and many thousands of buildings.
- Very simple, quick and robust construction method. Typically a
ThermoPlan Ziegel build is 3 or 4 times as fast as other masonry
systems - with less potential for problems.
- Excellent thermal insulation - good U-Values and very low
psi (Y) Values allow ThermoPlan Ziegel to perform incredibly well, with no
other insulation required.
- Good over heating control due to thermal mass of block.
- Simple route to good, long-lasting airtightness.
- Breathing construction - improving indoor air quality.
- Full system including all external and internal blocks, lintels,
mortars, plasters, renders, fixings etc
- Sustainable, achieving BREEAM Green Guide A rating
- MMC approved system
At NBT we offer full support from the start of your project -
offering design and specification advice to maximise the use of the
system. We then assist the contracting and QS process - ensuring
accurate costs and ordering. Finally we can offer a number of approved
contractors, or train any contractor to a suitable (approved) standard.
All this is part of the NBT service.

Warranties and Certification
These systems are fully certified and warrantable for use in the UK,
and have been used across the UK from the Orkneys to Sheerness, in
houses, schools and offices. They are the most common type of building
system in Germany, and are also the main systems used for super
insulated housing such as Passiv Haus. Currently awaiting final BBA
approval, the system already boasts LANTAC certification and warranties
from a number of sources.
ThermoPlan Ziegel Options
ThermoPlan Ziegel can be finished externally in a variety of ways - standard ThermoPlan Ziegel is finished with render, but
you can also Clad (in stone, brick, timber, terracotta or metal). ThermoPlan Ziegel can also be combined with Pavatex
woodfibre boards, and again finished in a clad or render finish. Click on the links below for some performance
