Physically correct sealing of building joints

Designers, installers and ultimately the inhabitants of the building
depend on innovative products, which make an energy-saving, reliable
and durable seal possible. Whether the fabric of the building remains
sealed

Our ISO-BLOCO 600 joint sealing tape has proven itself with regard to
weather resistance, thermal and acoustic insulation, moisture protection,
fi re properties, joint movement and a positive room climate.

Expansion joints make extreme demands
on joint seals

Reliable and permanent sealing of building joints is a vital part of the
planning of any building. To prevent the joints in exterior walls from
becoming weak points in the building fabric, attention must be paid to
functional and reliable joint sealing at the planning stage.

Particularly in the fi eld of facades, joint construction is subject to extreme
weather conditions and high physical stresses. Therefore it is vitally
important to use a sealing material which guarantees permanent functionality.

ISO-BLOCO 600  
remains fully functional,
even under severe stresses

Correct sealing of the joints is an essential component of a high quality
facade sealing system. For many years, ISO-BLOCO 600 has been
successfully used for the secure sealing of facade joints in both
renovation and new construction projects.

This pre-compressed, vapour-permeable joint sealing tape ensures
reliable removal of moisture from the inside, while providing durable
protection against rain and wind. As well as this, ISO-BLOCO 600 also
has excellent thermal and acoustic insulating properties.

As an ift-certifi ed BG 1 tape, it fulfi ls the stringent requirements of
DIN 18542, version 2009. A comprehensive examination procedure
confi rms the reliable functionality of the quality-tested sealing tape for
an extended range of applications.

As an energy-saving building seal ISO-BLOCO 600 complies with the
increased requirements of the German energy-saving standard EnEV
as well as other European (including UK) building standards and
regulations. Customers and installers can therefore be confi dent
that they have a seal which complies both with the requirements and
the recognised codes of practice.

Defective joints urgently need renewing

In the statistics for damage to buildings, damage due to the effects of
moisture now forms the largest group. But what are the causes?
Unfortunately, in many cases the use of unsuitable joint materials as
well as faulty planning and installation of the individual components
is responsible for severe damage to the building. The fact that this
damage not only occurs in old buildings, but also in new constructions
is especially worrying.

Once the fi rst signs of leakage appear, it is high time for action. If the
function of the joints is impaired, water can penetrate into the walls.
The usual result is severe damage due to damp with a dangerous
development of mould. As well as this, damp walls insulate considerably
less than dry ones. The draughts caused by defective joints then
contribute to an increase in heating costs due to unnecessary heat loss.

Joint renewal with ISO-BLOCO 600

For good reasons, ISO-BLOCO 600 has been used for many years for
the professional renewal of building joints. The BG 1 tape is tested
according to the current DIN 18542 and has all the properties which
are important for an excellent, durable, physically correct energy-
saving joint seal. Because of the material structure of the vapour-
permeable PUR sealing tape, condensation which occurs in the joint can
escape outwards in a controlled manner.

In addition, ISO-BLOCO 600 has an excellent expansion capacity and
guarantees the compensation of continuous movements. This prevents
the formation of water droplets, which can occur with other joint
materials such as fi llers. As well as this, having a rain protection
capability of over 600 Pa, ISO-BLOCO 600 keeps the weatherproofi
ng layer in the exterior region of the facade durable and securely intact.

All in all, ISO-BLOCO 600 is an EnEV-compliant joint seal, which protects
against unpleasant draughts, moisture damage and unnecessary energy
losses.
