Instructions to Lay Floor Components above Floor Heating

Wood responds to climatic impacts by fluctuating dimensions and, therefore, small gaps may occur. Thermal resistance of three-layer parquet MAGNUM: R = 0.14 m2 K W-1. Maximum humidity of the base on the laying day:  1.8 % of the cement finish as maximum and not more than 0.3% for the anhydrite base, when determined using the weight method. Before the floor is laid, you must issue a due report containing gradual temperatures, maximum temperatures achieved, operating conditions and outside temperature upon handover in case of both new and old base (based on DIN EN 1264 and DIN 4725). Base concretes before starting the heating mode must be at least 29 days old, under favourable climatic conditions. The starting temperature must be increased by 5°C daily during the warming-up until full heating performance is achieved. This temperature must persist for at least one day per 1 cm of thickness of heated screeds, without any night decline. Every day in addition is useful for humidity evaporation. Subsequently, reduce temperature daily by 5°C to reach 18°C - 20°C. Leave the heating switched off for the subsequent 7 days. From then on, increase the temperature gradually during 4 days to reach 45°C. After the temperature is reached, switch the heating off. Air the room continuously during this period and prevent draft of air. Having complied with these measures and having checked base humidity, the parquets may be laid.  Temperature of screed surface on the laying day: approximately 15°C - 18°C and relative air humidity: 45 - 60 %. 

How to Lay Floor above Floor Heating

In a floating manner - while laying the floor in a floating manner, you always have to lay a vapour barrier made of PE foil of 0.2 mm thickness and suitable impact insulation. In this case you must count with overall resistance of heat permeability as the sum total of each layer resistance.
By gluing parquets to the base - while laying the parquets you must use such glue which is designated to be suitable for floor heating by the manufacturer.
Switch the heating on 4 days after the laying.
a) In case there are several floor heating circuits in the room, separated from each other by expansion joints, you must admit the joints for parquets laid in the whole area on the surface of the parquets; in case of laying in the floating manner, heating must take place evenly for all circuits at the same time.
b) Upon the first putting into operation as well as at the beginning of the heating season, the floor must be warmed up gradually.
c) The surface temperature of the floor must not exceed 27°C in any part of the room.
d) In order to maintain floor stability, maintain ambient temperature at 18 - 23°C and relative air humidity at 45-60 %.

MAGNUM Parket, a.s., as the manufacturer, is not liable for any problems or defects that may arise out of non-professional preparation of the base, installation itself of the floor, exposure of the floor to unsuitable climatic conditions or unsuitable maintenance.
A guarantee claim cannot be asserted for defective components or components with a differing colour that have been laid.
