What's accoya ?My father was a carpenter joiner all his life , started when he 14 in 1950, for a while he had a joinery shop with a couple of older joiners working for him. Opinions varied but common threads were,
People forget about the old timber that rotted and was replaced ( Little Ron, spent his apprenticeship in london replacing / repairing rotted sash windows in the 50’s)
Best timber in the world won’t survive poor - construction, installation , care and maintenance. It’ll just last a bit longer
Never under estimate the importance of the elevation timber is on when considering why it rotted.
Just about any paint will work if applied properly to good joinery and maintained after.
People just don’t understand or want to know about maintenance and repair.
It would have been interesting if they were all still with us today to see what they made of accoya.
Basically Radiata pine pumped full of vinegar!What's accoya ?
Well yes but all the advantages are lost if the stuff fails too soon - usually long enough after the event to have any hope of getting any recompense.I think acrylic paints are getting better than they used to be. But one of the major reasons why they are used by the frame manufacturers is that it saves them money big time. Drying times a significantly shorter thus improving turnaround and due to low VOC content spraying facilities are much cheaper to run as they don't need expensive filter systems or furnaces to burn off rhe VOCs. Cleanup time on spraying kit is so much quicker and cheaper with water instead of nasty organic thinners which have significant disposal costs in a commercial environment
