Polyether-polyurethane foam materials impregnated with bitumen are disclosed.
These foam materials find use as sealing strips against moisture, draughts and
dust, particularly in the construction of roofs and walls of a building with
overlapping formed metal or cement or similar sheets where a strip is inserted
in the overlap of two adjacent sheets to provided the required sealing
therebetween. The sealing strips can also be used to seal adjacent tiles on a
roof between the underside of the tile and its supporting batten or rafter.
The bitumen may be a bitumen emulsion, hot bitumen or kerosene-diluted
bitumen. The concentration of bitumen in the foam materials can be in excess
of 600 kg/m3.
Cette invention se rapporte à des matériaux mousses de polyéther-polyuréthanne, imprégnés avec du bitume, qui trouvent une application comme bandes d'étanchéité contre l'humidité, les courants d'air et la poussière, notamment dans la construction de toits et de murs d'un bâtiment, avec feuilles de métal, de ciment ou de tout autre matériau similaire, formées en se chevauchant, dans lesquelles est insérée une bande au niveau de la région de chevauchement de deux feuilles adjacentes, pour assurer l'étanchéité requise entre elles. Ces bandes d'étanchéité peuvent également servir à sceller des tuiles adjacentes sur un toit, entre la face inférieure de la tuile et la latte ou le chevron qui la soutient. Le bitume peut être une émulsion de bitume, du bitume chaud ou du bitume dilué avec du kérosène. La concentration du bitume dans ces matériaux mousses peut dépasser 600 kg/m?3¿.
