Modular raised floors help to quickly level out any differences in the floor level and implement non-standard planning solutions.
They are expensive and are used in apartments mainly to solve non-standard problems, such as the construction of podiums of considerable height or the installation of ventilation and air conditioning ducts under the floor based on low-power units.
The main parts of the raised floor are support posts, stringers and slabs. The most common size of slabs is 600 × 600 mm, and the height of the supports varies from 50 mm to 1.5 m.
The supports can be made of plastic (hard PVC, polyamide), steel or a combination of these materials. The floor elements are mainly made of high-density chipboard 38 mm thick. To prevent formaldehyde emissions, they are covered with aluminum foil along the plane, and PVC tape along the edges. The cost of a set of parts starts from 2,200 rubles per 1 m2.
A more environmentally friendly solution is reinforced gypsum boards (on company websites you can find the name “Calcium Sulphate”), reinforced with a steel sheet, but they are twice as expensive as chipboard.
