The water vapour diffusion resistance of timber materials were tested in a wet climate (relative humidity ranging from 100%to 65% at 20 °C) and in a dry climate (relative humidity ranging from 0% to 65% and from 0% to 35% at 20 °c) with variation by relative humidity and vapour pressure gradient. The diffusion resistance of multilayer solid wood panels lies under or within the range of the solid wood (spruce), tending even to a lower range. This can be attributed to the loosely inserted middle lamella of the used solid wood panels, which were not correctly glued by the manufacturer. The diffusion resistance of the solid wood panels increases with decreasing moisture content and decreasing panel thickness, as well as with increasing water vapour gradient from 818 to 1520 Pa. There were clear differences between the tested timber materials. The diffusion resistance of particle composites is strongly dependent on the specific gravity. Due to laminar particles OSBs(Oriented Strand Boards) have a larger diffusion resistance than chipboards. The water vapour diffusion resistance of OSBs lies within the range of plywood.

This study estimated the sawn wood demand price and income elasticity. Specifically it was estimated the price elasticity of sawn wood, the cross price elasticity of wood panels and the income elasticity of Brazilian GDP. A log-log model with correction through outline of the mobile average (MA(1)) was used, adjusted for the period of 1971 to 2006, which showed to be stable, with satisfactory significance levels. It was observed that sawn wood demand is inelastic in relation to price and elastic in relation to income.

King's Place is a singular venue. A relative newcomer to London's range of concert halls, comprising multiple spaces that are of a matching bright and clear acoustic – very well-researched when designed, no doubt. Clean lines and wood panels abound: there are loads of loos and plenty of places to put your coat or pick up a drink. On paper it is the perfect venue for a contemporary classical concert.
