Sealing | sealant types
General
The sealing work (caulking sealants) must be
carried out in accordance with current stan-
dards.
When stuffing the insulation material into
the gaps make sure not to add too much as
this will cause the frame parts to curve.
If any foaming insulation material is used,
the frame must be reinforced or in some
other way secured until the foaming process
is finished completely.
Always finish off with a protective cover on
the outside such as mastic, sealant tape or
similar material.
Sealant type
There are a wide range of sealing products
tochoose from for use between frames and
outer walls.
The two most common types are:
•
Plastic or elastic mastic
•
Asphalt saturated plastic foam
(
Illmod sealing tape)
In order to preserve the wood and keep heat-
ing consumption low it is important that the
sealing work stays intact.
The sealing work should therefore be in-
spected at least once a year, and any leaks
should be remedied using the same type of
material as the existing one. In case of any
major leaks, all the sealing material must be
replaced. In such cases it must be assessed
whether a different type of sealant would be
more suitable than the existing one.
