The invention relates to a spacer for multiple-glazed
insulating glazing, comprising a base element (5), which has two
parallel contact surfaces (9, 11) for the glazing panels (1, 3), and
an adhesive surface (19) which is turned away from the inner
space of the glazing unit and connects the two contact surfaces.
The base element (5) is made of fibreglass reinforced plastic.
Said spacer is characterized in that a metal foil (21) is glued
against all of the adhesive surface (19), and in that by selecting the
proportion of fibreglass in the plastic matter of the base element
it is possible to match the coefficients of thermal expansion of
the base element and the metal foil. This type of spacer ensures
especially good leak tightness and lasting bonding between the
plastic spacer and the metal foil, and between said metal foil and
the sealant between the glazing panels.
L'invention concerne un écarteur pour vitrage isolant à vitres multiples, comprenant un corps de base (5) présentant deux surfaces d'appui (9, 11) pour les vitres (1, 3), s'étendant parallèlement entre elles, et une surface de collage (19), orientée à l'opposé de l'espace intérieur du vitrage et reliant les deux surfaces d'appui, le corps de base (5) étant fabriqué en matière plastique renforcé aux fibres de verre. Cet écarteur est caractérisé en ce qu'une feuille métallique (21) est collée sur toute la surface de collage (19), et en ce qu'en choisissant la proportion de fibres de verre dans la matière plastique du corps de base, il est possible d'équilibrer mutuellement les coefficients de dilatation thermique du corps de base et de la feuille métallique. Un tel écarteur permet d'obtenir une excellente étanchéité et une liaison durable entre l'écarteur en matière plastique et la feuille métallique, ainsi qu'entre cette feuille et le produit d'étanchéité se trouvant entre les vitres.
