Cressington Engineered Golden Oak Brushed and Lacquered 125mm x 10/2mm Wood Flooring. A fantastic Golden Oak engineered wood flooring. Each individual board is 125mm (12.5cm), the overall thickness of the plank is 10mm (1cm), including a top 2mm layer of Oak veneer. The 2mm wear layer enables you to sand down and refinish the surface at least once. This shouldn’t be necessary for the first 10-15 years in most domestic environments. Engineered flooring, such as this, is highly resilient to temperature and humidity changes meaning they can be laid in most rooms in the home, including conservatories, with the only exception being the bathroom. Due to the stability of our engineered flooring products laying the flooring in rooms heated with water-based underfloor heating is not a problem. Each board is manufactured with a tongue and groove profile, so each board can simply be glued together. The grade of this Oak is mixed, meaning it will contain some knots as is typical with Oak products. This engineered Oak would usually be fitted as a floating floor installation, where a 3mm underlay is laid onto the subfloor beneath the flooring, this gives added protection from any damp and will act as a sound barrier and insulator. Our 4mm Compressed Rubber Underlay is suitable for water-based underfloor heating.
