Section member and fitting assembly for making high thermal insulation wood coated window and door frames

摘要

The present invention relates to fixed frame section members and/or movable frame section members, each constituted by a metal outer section member (31) and a metal inner section member (32), connected to one another by thermally insulating material elements (3,4). The metal inner section member (32) is provided, on the inner face thereof, i.e. the face thereof opposite to the metal outer section member (31), with a seat in which restraining plugs can be engaged, the latter being affixed to a wood coating strip (45). These plugs are provided with a first portion thereof which can be engaged in the seat of the metal inner section member and a second portion which can be arranged between the inner face of the metal inner section member and the wood strip, so as to space the wood strip from the metal section member.
