    AI Overview
    18(4)x300 Unfinished Extra Extra Wide Board
    300mm wide engineered oak flooring provides a grand, spacious look, typically featuring a 4mm–6mm solid oak wear layer on a stable 15mm–16mm plywood base. These boards are usually 18mm–21mm thick, 2200mm long, and suitable for underfloor heating. Options include unfinished, natural oiled, and prime grades. 
    Key Features & Specifications 
    • Dimensions: 300mm width, often with a 2200mm length.
    • Thickness: Generally 18mm to 21mm, with a 4mm–6mm wear layer.
    • Stability: Plywood backing prevents cupping/warping.
    • Finish: Available in unfinished (raw), natural oiled, or smoked finishes.
    • Installation: Suitable for gluing, nailing, or floating. 
    Common Options & Suppliers 
    • Oak Floors Online: Offers 18(4)x300mm unfinished, extra-wide boards.
    • Old Oak Floors: Stocks 18mm thick, 300mm wide unfinished oak.
    • Naked Floors: Provides 21mm thick options with a 6mm top layer.
    • Broadleaf Timber: Features 300mm wide "Classic" extra-wide oak.
    • Engineered Flooring: Offers 300mm raw oak planks. 
    Important Considerations 
    • Stability: Because of their width, 300mm planks require proper installation (usually glued down) to maintain stability.
    • Wear Layer: A 4-6mm wear layer means these floors can be sanded and refinished, similar to solid wood.
    • Appearance: These boards create a modern yet rustic, "grand" appearance, reducing the number of joints in a room.

    What is the best thickness for engineered oak flooring?
    High-traffic areas benefit from thicker boards (18-20mm) with substantial wear layers (4-6mm), while moderate-use areas typically do well with 14-15mm boards with 3-4mm wear layers. Choosing the right thickness of engineered wood floor is crucial based on room usage and foot traffic to ensure durability and longevity.Feb 26, 2025
