Timbers Glacial Oak

Timber windows and doors made from ASH’s brand of American Oak – Glacial Oak – are arguably the best on the market.

Perfect for traditional style homes or architectural masterpieces, hardwood windows are naturally hard-wearing, strong, energy efficient and visually stunning.

Glacial Oak is straight line edged after drying, has minimal pink colouring, is internally scanned for defects and is available either as solid timber or finger-jointed material.

Companies incorporating our hardwood timber in their construction have been able to achieve BAL29 and BAL40 (Bushfire Attack Level) rating, although the timber properties naturally achieve BAL-19 without additional tests.
