Abstract: Disclosed is a footwear device for moving around on walls made of perforated plates, having an innerboot secured to a sole made of flexible plastics material, extending along a longitudinal axis from a heel to a tip, the sole having a semi-rigid plate, known as a core, embedded in the thickness of the sole. The core is designed to receive one or more rigid fingers that are able to pass into a hole in the wall made of perforated plates, the finger extending along the longitudinal axis and protruding from the front of the sole.

Abstract: A device (2) for thermally insulating a building wall (1) from the outside, being applicable in particular to walls and roofs, includes, starting from the wall, a layer (3) of impermeable rigid insulation, spacers (4) and a perforated rigid facing sheet (6) at a distance from the layer (3) of rigid insulation so as to form an air gap (7) between the facing sheet and the layer (3) of rigid insulation. A layer (8) of granular insulation (9) in divided form is contained in synthetic textile bags (10) placed in the air gap (7). A method for implementing such a device is also described.

Abstract: The “heat- and wind-screen for the building industry” is an original and economical concept that increases comfort inside buildings subject to strong solar radiation. It comprises cladding the roof and/or the walls with perforated metal sheets and using spacers having an original design and disposition. The investment is low due to the proposed mounting mode and the low cost of the materials used. Savings can then be achieved by reducing the energy consumption for the air-conditioning of the building. The structure of the “heat- and wind screen for the building industry” induces important load losses for the winds on their path about the building and the building it covers exhibits a better resistance to strong winds.
