Professor Callum Hill’s update on the positive environmental impact of wood

In a review of the environmental impact of wood products, leading Welsh wood scientist, Callum Hill shows that timber products lock-up more carbon than is used in their production. The study also shows that generic embodied carbon data quoted from independent databases such as the Inventory of Carbon and Energy (ICE) tend to underestimate the benefit of wood.

Japanese Larch and its Innovative Applications in Construction

The Wales Forest Business Partnership (WFBP) have surveyed 55 Japanese larch sites across Wales and estimate that 4.9 metre sawlogs make up 24% of the total crop of 1.89 million cubic metres. This could produce around 1 million cubic metres of sawnwood or 50,000 timber framed and timber clad three bedroomed houses. Add in projected volumes of sawnwood from The Marches and these figures increase to anything between 68,750 and 76,725 houses.

The purpose of this survey is to determine the quality of the larch resource in Wales, and extrapolate this data for the Marches.

Thermal Mass Leaflet

The ability of a property to maintain a constant habitable temperature is essential, and depends not only on the ability of a construction to keep its heat through correct insulation, but its ability not to absorb or lose heat to the environment. This is mainly linked to the ability of a material to absorb and release heat, and is known as its thermal mass.

Perceptions of quality in homegrown Douglas fir

Douglas fir has significant economic importance in NW America, New Zealand and parts of Europe, especially France and Germany. Roadside prices for logs are considerably higher in Germany than here in the UK where logs from 50 year old trees can make up to 140 Euros per cubic metre.

Wood Strength Testing

Hand-held strength grading tools utilising acoustic technology have been discussed for several years and the question keeps arising “when will they be available for use by SMEs?”
