If carefully installed and well monitored after installation, with sensible running of the heating system then yes, it may be used over a heated concrete slab. Reconstructed does not warrant installations over heated subfloors due to the many uncertainties involved. However, our product has been successfully installed on numerous occasions by persons experienced with such installation methods.
It is recommended that the subfloor be heated to its normal operating level for 14 days to remove excessive moisture, then turned off for two days before installation to ensure the heating has no adverse effect on adhesive or timber, and then gradually increase the Under Floor Heating (UFH) to normal expected temperature.
The heating should be increased in stages from a low level to the desired room temperature over a period of about 10 days, incrementing by no more then 2°C each day and then maintained for a further two weeks.
If the floor has been sanded and coated, recommendations vary with this, with some coating manufactures indicating that it should be carried out about three days after the heating was turned back on, while others indicate the heating should be turned off and the floor sanded two days after the floor has cooled.
It will be up to the sanding professional to be aware of what the manufacturers recommendations are for the product used. The heating operating panel is to be fixed at a maximum of 27°C for the lifetime of the floor, this will need to be strictly adhered to. Engineered flooring installed over slab heating can still be expected to shrink however the amount will depend on the in-service room temperature and relative humidity. With a heated concrete slab the optimum relative humidity range is between 45%-60% year round with room temperatures of about 18°C to 24°C.
This depends on the circumstances. In most circumstances little or no acclimatisation is required. However, it is imperative that the flooring installer takes a moisture reading of the engineered flooring to ascertain suitability for the given installation site. The flooring should not be any more than 1-2% different than the normal EMC (Equilibrium Moisture Content) level for that given area.
If the EMC is expected to be 10% and the flooring is 10%, then no acclimatisation is required. However if the EMC is expected to be 13% and the the moisture contenct of the timber is 10%, then it must be allowed to accimatise.
This is most effectively done by being racked out or stacked in the room of intended installation with in-service conditions being applied. Opening cartons and leaving in the garage is not appropriate in-service acclimatisation, neither is leaving the timber inside the cartons in the room it is to be installed.
Reconstructed produce our products in two grades: Premium and Rustic.
- Premium (Standard and Better)
This is our highest grade and can contain a very subtly amount of natural occurring features. This grade of flooring once installed presents a uniform, natural look. As timber is a natural product, this grade of timber flooring will contain some degree of feature such as pin holes, gum vein, surface checking, knots, sapwood, natural occurring stains, black specks, burls and hob nails. The premium appearance of this grade is ideal for the most discerning eye.
- Rustic (Standard and Feature)
This grade is carefully selected to include the most natural and interesting features to enhance the natural appearance of your timber floor. This grade may contain screw holes, nail holes, saw cuts, large knots, gum vein, pin holes, surface checking, splits, cracks, man made features and other natural occurring features that are filled during manufacturing to lessen the amount of work required onsite. Rustic grade presents a timber floor to you the way mother nature intended with very little done to adjust this natural featured grade appearance.
Reconstructed do not sell our products as ‘colours’ but as ‘species’. This is due to timber being a natural product and within each carton there will be a variety of natural colours pertaining to the certain species and in some cases a mixture of species. The colour variation present in these species is what makes each floor unique, so it is expected to have colour variation between cartons and across the entire floor. When it comes to recycled timber, you should expect colour variation amongst a species and a mixture of species at times due to it being reclaimed and often similar looking species will be mixed together.
