However all went smoothly and by 4pm the building had a roof on.
Why from Poland? Much of our construction timber is sourced from overseas. In Poland they make Steico I-beams [joists made of a thin central core of manufactured board with timber at each end] which are less termally conductive and also stronger for given size than solid timber. Steico also make insulation from wood fibre. So a Polish factory can construct competitively an excellent quality wall/roof frame from I-beams, fully filled with insulation and clad on the ouitside with a further 100mm of insulation.
Windows were fitted later after these pics - they were supposed to be fitted in factory, but arrived on the back of the lorry.
