BOEN sports flooring is an ideal floor covering for placing on top of under-floor heating systems having favorable thermal resistance properties. Hardwood, being a hygroscopic material, is very susceptible to movement when exposed to different humidity levels especially Beech and Maple. Hardwood floors absorbs moisture from the atmosphere when humidity is high (normally during the summer months), causing expansion; whilst in the winter months when the heating system is in operation and humidity is low, the floor will shrink, therefore some movement in the floor may be possible. A well-functioning under-floor heating system, hot water or electrical, results in ideal thermal distribution throughout the area to be heated, giving maximum comfort. It is therefore necessary for the floor-covering to have good thermal conductivity, i.e. Low resistance to heat transmission. There are many different types of under-floor heating systems available, e.g. Electric cable, hot water pipes and low voltage foils, the majority of which can be used together with BOEN Sports flooring.

Major requirements concerning concrete screed
The screed must be laid according to contractual specifications and planning authority requirements. When overlaying screed, moisture must not exceed 1.5% CM or max 75° RH when the hardwood flooring is laid. Ideally the screen will have been laid at least 4 weeks prior to the heating system being used. The first time the heating system is used it should be run at 2/3 output for at least 2 weeks so that escaping moisture can evaporate without causing damage and the screed can dry and attain its final moisture content.
1 week before the hardwood flooring is laid the heating should be reduced to approx 18°C/64°F.
If the heated under-floor is concrete screed, this should be covered with a layer of suitable non thermal resistant underlay as a compensation layer and for muffling step sound. The electrical cables or water pipes must be covered by 30mm reinforced concrete/levelling screed.
Before laying commences refer to Boen’s laying instructions.
The hardwood flooring boards, which are pre-packed in a heat-shrunk wrapper, must not be opened until immediately before they are laid. About two days after the parkett has been laid, the temperature of the under floor heating system may be gradually raised over a period of one week until the desired temperature has been obtained.
The under floor heating system must be regulated to ensure a max of 60W/m2 with a sub-floor surface temp not exceeding 27°C/83°F, with a room temperature of 17-18°C/62-64°F. RH should be maintained between 30-60%. Heat must be evenly distributed under the hardwood flooring.
No carpets with insulating effect must be used on top of the floor as this accumulates heat.
