Recommended Floor Insulation Thicknesses in Cold Rooms

Recommended Floor Insulation Thicknesses in Cold Rooms


It is necessary to use a continuous and reliable thermal insulation in order to save energy, protect the cold room and prevent heat losses that may occur on the floor. Regardless of the condition of the existing cold room or any cold store under construction, a thermal insulation layer can be placed under or on the floor concrete. In the section below, the floor structures where thermal insulation is used under the base concrete are described and the types of loads they are exposed to are listed. Thermal insulation boards used in foundation walls and floors; product loads to be stored forklifts must withstand the loads of high racks:

Recommended floor insulation detail is shown below

1-) Square Mosaic (3 cm)
2-) Cement Mortar Screed (3 – 5 cm)
3-) Reinforced Concrete (5 – 7 cm)
4-)Styropor (10 – 15 cm)
5-) Steam Cutter
6-) Unreinforced Concrete (10 – 12 cm)
7-) Blockage (5 cm)


GROBETON is to cut the contact between the ground and the foundation, to prevent water or harmful chemicals from the ground from damaging the foundation reinforced concrete, and to bring the foundation to the level necessary for laying the reinforcement.

STYROPOR is a hard, insulating, lightweight, polystyrene-based plastic. It is generally used for preservation and isolation purposes. STYROPOR is a petroleum (derivative) by-product. It has the lowest heat permeability among its other peers; It is produced in various densities between 8gr/dm3 and 100gr/dm3 and has wide application areas.

STEAM SHUTTER It removes the steam produced to increase the durability and energy efficiency of the buildings exposed to cold, moisture and steam, and thus prevents corrosion of the building elements over time. In addition, it ensures that the cooled air remains inside the building by preventing air losses and provides energy savings of up to 30%.

BLOCKAGE is the recommended layer to be poured under lean concrete, usually consisting of stone chips or crushed rubble, with a thickness of 15 cm. It is a good precaution against water with its intermittent structure.
