For installation in insulated façades: Recessed housing 13519 with five optionally usable insulating elementsThe recessed housing 13519 from BEGA is suitable for the installation of luminaires in insulated facades. The scope of delivery includes one insulation element with a depth of 3 cm and four insulation elements with a depth of 2 cm. The modular design and the composition of the individual insulation elements in steps allow flexible adaptation to the insulation system. Thus, it can be used for insulation thicknesses of 12 to 20 cm.A comprehensive test certifies that this built-in casing is free of thermal bridges (test by Passivhaus Institut Dr. Wolfgang Feist). The additional increase in the regular heat transfer coefficient of the wall is ΔU < 0.01 W/(m² - K). A plastering frame is required for plastering in the housing - optionally for surface-mounted or flush-mounted installation of the luminaire. Plastering frames are supplementary parts and must be ordered separately (see accessories).
