In general, plastics do not have a negative influence on aluminium. Putty, on a basis of lime and
linseed oil, for windows causes no danger to aluminium. Neither do gaskets or synthetic gaskets
(EPDM). The same applies to synthetic materials containing chlorine, e.g. PVC. These should
however be of very good quality and the chlorine should not be allowed to come into contact with the
aluminium. Silicone and silicone gaskets are also applicable on the condition that they do not contain
chlorine or acid. Most pointing pastes for brickwork are not dangerous.

ALLOY AND INSULATION
I.3.1
Alloy
The great advantage of the use of aluminium for outside constructions is that it is a stable, corrosion-
resistant and yet light material. Its density is 27 kN/m² , approximately 1/3 of the density of steel. It can
be processed at high cutting speeds, which reduces the fabrication time.
The Reynaers constructions are fabricated using extruded aluminium profiles and rolled aluminium
sheets. The most current indications are:

(anodization quality)
I.3.2
Insulation
Two types of products can be used for the thermal break of the aluminium profiles:
- polyurethane
Properties of the thermal break with polyurethane:
- two component polyurethane;
- temperature resistance: minimum -30°C, maximum 75°C.
Composition of the thermally broken profiles:
- an aluminium chamber of the profile is filled with the polyurethane (PUR)
or injected with foam; after polymerisation of the thermal break,
the aluminium connections are removed in a milling operation.
- double polyamide strips
Properties of the strips:
- composition: glass fibre-reinforced (25%) polyamide fitted with polyethylene adhesive
inserts;
- temperature resistance: ≤ 250°C;
- coefficient of thermal expansion: a = 20 x 10
Composition of the thermally broken profiles:
- strips which make the connection between the inner and outer profile halves;
mechanical anchoring of the strips by means of the rolling process, after knurling of the strip
grooves.
The two insulation principles are subjected to periodical controls by an independent organisation.
The insulators are CFC-free.
