"The aim of the SILENTWOOD project is to develop and validate a novel, price-competitive, certificable exterior wooden-based door with enhanced acoustic performance to attend the growing demand and comply with increasingly stringent building legislations for residential, educational and sanitary premises. It will also cope with the broadest range of aesthetic and architectonic variables and applicable world-wide standards (i.e. in relation to thermal insulation, fire-proofing and mechanical properties). It will be based on an innovative multilayered structure containing new noise reduction materials and attenuating internal geometrical design. The purpose of SILENTWOOD is to allow the impacted sectors to comply with existing building regulations at European level and, at the same time, opening them the door to new market opportunities to help them face their current critical situation. This aim can be divided into two general objectives: 1.Develop the sound-insulating sandwich or multilayered structure, containing new noise reduction materials and designing an innovative attenuating internal geometrical design. 2.Test, validate and certify the door full system, firstly using computer models for optimization and rapid prototyping purposes and, secondly, carrying out standardised tests. The participant SME-AGs have recognised the need to find a technological solution to its associated SMEs and the appropriateness of the solution presented in Silentboard. However, they do not consider themselves, nor the SMEs they represent, to have the technical capabilities to drive the necessary R&D activities at the level of excellence required for such development, as this would require the combination of expertises in fields such as materials, engineering, computer sciences, acoustic and physics. For this reason, the associations of this consortium agree on the need to contract R&D services with a range of specific expertise."
