If a 50% wet log is burnt at high temperature, with good heat extraction from the exhaust gas leading to a 100 °C exhaust temperature, about 5% of the energy of the log is wasted through evaporating and heating the water vapour. With condensers, the efficiency can be further increased; but, for the normal stove, the key to burning wet wood is ...
Health concerns around mould include infections, allergenic or immunological illness, and nonallergic illness. Asthma is also triggered by the sensitization of dust mites accruing humid, wet regions of a structure. [4]: 146 Another health effect associated with structural dampness is the presence of bacteria in an indoor environment. Bacteria ...
Different types of wood warping. Wood warping is a deviation from flatness in timber as a result of internal residual stress caused by uneven shrinkage. Warping primarily occurs due to uneven expansion or contraction caused by changes in moisture content.

Dry boards naturally creak under pressure, but these floors were built in a way that the flooring nails rub against a jacket or clamp, causing chirping noises. It is unclear if the design was initially intentional. It seems that, at least initially, the effect arose by chance.

Three of the processes are performed in one step, using oil (oil-heat treatment), nitrogen (Reti wood) and steam (Le-Bois Perdure). [1] The Thermo wood process consists of drying, heat treatment and finally cooling/conditioning, and takes up to 72 hours. [4]
Polymer formworks can suffer from sudden failures during casting, which are generally associated with the pressure exerted by the wet concrete on thin plastic formworks. Such failures can be substantially accelerated by the corrosive effects of the wet concrete paste, which has a pH of circa 13.
