From where do Junckers get the solid hard wood sports floors? Junckers do not import floor boards. We manufacture the floor boards and control the complete process in our own factory in Køge, Denmark. 2. Do only solid hard wood floors get affected by moisture fluctuation in the environment? No, all types of wooden floor boards absorb humidity from the air and will expand and contract during a season. 3. Why do you sometimes see floor boards cupping or crowning? Cupping or crowning occurs on both solid hard wood floor boards and engineered floor boards when installation of the floor is not done in consideration of moisture fluctuation in the surrounding environment or according to the laying instruction. Also poor site conditions like moisture from the sub floor or heavily use of water can create this type of problem. 4. Do solid hardwood floors expand and contract more than engineered floors? Climate chamber tests show that engineered floors expand and contract less than solid hardwood floors. Engineered floors however, only function in environments with limited moisture fluctuation, typically 35-65%. Due to lack of flexibility in an engineered floor board, it is common to see tension between the different floor board layers and this creates a very high risk of delamination. 5. Is Junckers solid hardwood floor more stable than an engineered floor board? Yes, this because you get a floor very durable, tension free, resistant to indentation and able to cope with huge load capacity. These properties are obtained through our 80 years of experience and special developed production methods. 6. Do I need dilatation joints in a Junckers sports floor? No, due to the built in expected moisture fluctuation, dilatation joints are not needed. 7. Is a solid hard wood floor expensive to maintain? No, a Junckers hardwood floor is delivered with a long lasting and hard-wearing surface treatment of polyurethane lacquer and vacuuming, use of a micro-fibre mop or a well wrung cloth on a daily basis is more than enough to keep the floor in good shape. 8. How many times can a Junckers floor board be sanded? 8-10 times due to the 9.5mm wear layer. In average 5 times more compared to engineered flooring. However this is only needed, if years of very hard wear demand a more comprehensive renovating. Usually a light screening followed by one coat of sports lacquer is more than enough to keep the floor in shape. See more here 9. Is the stability of the floor affected when sanding down to the upper dovetail joint? No it has no relevance for the stability as the floor board has two dovetail joints.
