Description
Laboratory measurements in accordance with EN ISO 10140-5:2021 are used to analyse the rain sound insulation of timber roof constructions with varying structural configurations. Rain induced sound intensity levels are examined for exposed-rafter roofs and timber frame roofs with aluminium sheet, zinc sheet, and two types of tile cladding (sliding tiles and beaver-tail tiles). The influence of additional underlays beneath the metal cladding — a bituminous membrane and a structured mat — is investigated. The effects of PV elements on tile- and aluminium-sheet-clad roofs are also examined, as is the influence of a roof window with and without a roller blind.
