Ronseal
Manufacturer data for a two part exterior grade wood filler. It dries in 30 minutes and can be filled to any depth, and the formula is stated not to shrink or crack even in harsh weather. The working window is roughly 20 minutes to carve or shape the filler before it hardens, and it should be smoothed over with a knife before it sets. The 20 minute working time against a 30 minute dry is why this filler is mixed in small batches rather than a whole tub at once.

Saint-Gobain Glass UK
Saint-Gobain ORAE, described as the lowest-carbon flat glass in the Saint-Gobain range and the world's first EPD-verified lower-carbon glass. Carbon footprint 5.88 kg CO2e/m2 for 4mm glass, made with 64% recycled content (as defined in ISO 14021) and renewable electricity. Available 4mm, 6mm, 8mm, 10mm and 12mm; COOL-LITE XTREME ORAE is available in 4, 6, 8 and 10mm. Saint-Gobain states ORAE and standard flat glass achieve the same light transmittance, U-value and g-value, so the saving is embodied carbon rather than performance. For partitions, balustrades and balconies it should be specified laminated and toughened.
