Location of Installations Without Opening Chases in Ceramic Walls

Abstract

To open chases in a wall, made of ceramics bricks, blocks or thermal blocks is, actually, a traditional locating system for installations. It is an expensive, slow, dangerous and destructive system prone to diseases. Traditionally the parameters of thermal conductivity and acoustic insulation of a brick, ceramic block or thermal blocks provided by a manufacturer, have been the result of executing a wall (partition or structural wall) made of that material, but without the opening chases. Companies have been giving some values which really could not comply with regulations. The way to solve this failure to comply is twofold. The first option is to endow the ceramic piece with some safety co-efficient, as far as acoustic and thermal insulation is concerned; so that once the installations have been located in the different chases they meet the minimum requirements set by the regulations. The second option, subject of this paper, is to locate installations within the same geometry of the ceramic piece and so, three patents will be explained briefly to illustrate this point. The European guidelines in the field of energy efficiency in 2010 (2010/31/UE, 19 May), and 2012 (2012/27/UE 25 October), together with the 2013 Spanish executive orders, RD 238/2013 (Regulations for the Thermal Installations on Buildings, RITE, modification) and RD 235/2013 (energy efficiency), severely penalize worsening/weakening of passive conditioning and more specifically, they severely penalize the opening of chases. Therefore, it is time to look for eco-solutions to secure a safe and efficient commercialization of the ceramic closing/wall.
