We offer wooden slats for installation and can remove the cross bracing in individual cavities upon request, or use joinery machines to cut grooves. For surface elements, we can also move the upper slat downwards.

Single vertical penetrations are possible withoutstructural reinforcement in the area of the cavity,with the box element up to 130 mm and with thesurface element up to 200 mm.

The cross distribution is easiest if done in the zoneof the bearing. Of course, services can also beinstalled in a sound insulation layer or in bondedchippings and the underfloor heating be put inthe screed.

Almost all lights can be fixed to standard flammablebuilding materials like wood – LIGNATUR.Lights that do not fulfil the requirements have tobe labelled specifically according to EN 60598-1:2008. On all flammable surfaces that are influencedthermically by the lights, no higher temperaturesmay develop in normal operation.We therefore recommend using only lights withaluminium reflectors.
