Havwoods’ Bog Oak flooring is derived from semi-fossilized trees in European lakes, rivers and peat bogs, where they were preserved and transformed over centuries to create intricate patterns. The 3/4 inch thick wood has deep ebony hues, a 5 mm wear layer and is available in various widths (9 7/8 in. – 13 ¾ in.) and lengths (78 3/4 in. – 157 1/2 in.) It can also be suitable for underfloor heating.
