For aluminium cladding of PVC windows and doors
General requirements
The aluminium profiles are to be offered in anodised EN AW-6060 T 66 and in accordance with DIN EN 12020. Building
must follow all relevant standards and guidelines, common laws of engineering as well as the system
developer's specifications. The offered system is to feature the following properties verifiably:
Construction
Window construction
The window construction must be performed in accordance
with the system information provided
by the PVC window systems suppliers and all
other specifications. The structural requirements
must be met by the unclad PVC profiles alone.
Aluminium frame
Provide an offset system. Frame and sash are offset
approx. 20 mm. Aluminium sash profile and glass are
offset 25 mm. Frame profile and crossbar / mullion /
transom must each be offset approx. 1 mm at the joint. The
aluminium profiles must be rounded with a radius of 2 mm.
The rebate area is drained invisibly via concealed drainage
openings or visibly with drainage caps.
Before being mounted on the PVC frame, the aluminium
profile corners must be preassembled into complete frames
in order to ensure plane and closed corner joints. The
aluminium frame must never be mounted in its individual
pieces as this impacts the quality of the mitre joints. The
aluminium frame must be able to be joined either
mechanically or welded.
The following types are intended:
mechanical connection (punched)
welded connection
Attaching the aluminium frame
The aluminium frame is fastened on the plastic frame via
PVC clip-on profiles that are clipped into the aluminium
profiles and glued to the PVC frame with cold weld
adhesive. Only adhesives approved by the respective PVC
systems suppliers must be used. In addition, the system
offered must also allow the aluminium frames to be
fastened via screwed clip-on holders if necessary. The
tension-free expansion of the aluminium shell towards the
PVC frame is ensured by using elastic clip-on profiles to
prevent the opening of mitre joints during linear extension
caused by temperature changes.
Gaskets
As a gasket for the outer seal between glass and frame
and between sash and frame, we recommend using PVC
window system gaskets that project approx. 3 mm from the
overhang and thus lie flush with the aluminium shell.
The aluminium profiles are to be offered either with
anodised surfaces in accordance with DIN 17611 or
powder coated according to GSB or equivalent.
