Insulation fasteners
Insulated cladding and rainscreen systems - Definitions and application of Exterior Thermal Insulation solutions in dry construction methods

The insulation must be fixed to the building's supporting structure in accordance with the insulation manufacturer's instructions. The fixing devices used may be specific to the type of insulation being fixed. Certain normative texts, such as the Cahiers du CSTB or DTU 45-4, specify a few minimum rules on fastening elements (e.g., minimum flange diameter) or installation (e.g., minimum fastener density). Several types of fasteners are commonly used to attach insulation to cladding.

Mechanical fastening is a commonly used method for securing insulation in cladding systems. It involves using dowels, screws, nails, or toothed brackets to attach insulation panels to the building's supporting structure, whether concrete, masonry, or wood. These products are quick and easy to install and offer good mechanical strength. However, these techniques have the disadvantage of...
