DTU AND REFERENCE STANDARDS

STANDARDS / DTU / QUOTE

The DTU (Codes of Construction Practice) apply to building work. They offer standard clauses for traditional techniques. They represent what is commonly done. Insurance or court-ordered experts frequently use their content, which refer to as "trade practices". FRENEHARD designs its products by accounting for the requirements of various DTU and technical specifications from the CSTB. The compliance of FRENEHARD products, whether they're designed for safety or not, may only be guaranteed of their implementation is compliant with the DTU and if they're installed in/on structures which comply with the reference DTU. Refer to the CSTB or AFNOR websites for the DTU. DTU 40.11 Slate roofing

OTHER REFERENCE DOCUMENTS: Mountain-climate roofing guide: This reference technical guide applies mainly to the creation of roofing with discontinuous elements in mountain climates for residential buildings or for buildings for public or social use in the tertiary sector. Specifications 3316_V2 - December 2010: Creating structures with wooden framework These specifications mainly apply to the creation of structures with wooden framework and thermal insulation for exterior cladding, subject to a technical opinion or a confirmation of traditionalism. Specifications 2352_V2: FIT classification The FIT classification (F - Fatigue, I - Indentation, T - Temperature) is a performance-based classification for impermeable coatings for roofing with the aim of providing a simple response to satisfying the suitability for use for certain performances, for which various levels have been determined, corresponding to various usage solicitations.
