WHY HAVWOODS' TIMBER WON'T LET YOU DOWN
No matter how well seasoned, oiled, waxed or lacquered it may be, wood remains hydroscopic. This means that when the humidity is high it will absorb some of that moisture, swell and rise or ‘crown’ in the middle. If that same piece of timber is placed in a dry environment – as happens when using heating or air conditioning – it will release its moisture, dry out and shrink. Lay pieces of timber side by side in a confined space and those changes in humidity, over time, may well result in them bowing, warping, cupping or gapping – gaps between the planks. This is what can happen with a solid wood floor, wall or ceiling.
