Abstract

Aluminum window or door with thermal break comprising a frame and a sash having a first inner profile and a second outer profile connected to each other by means of a third profile made of thermally insulating material; said third profile has, in cross-section, a first side having two contiguous teeth engaged in respective contiguous seats present on said first profile and a second side having a single tooth engaged in a respective single seat of said second profile, said single tooth being positioned so as to leave a large part free of said second side for the engagement of the latter with a time stripper for said sash, further providing a compensation means on said third profile to compensate for the different thermal expansion of said first and second profiles with respect to the thermal expansion of said third profile.
