Thanks Milkfloat .
My take on things .
Pretty much all joinery in this country for the last few hundred years + has been made from redwood and everywhere you look it is still there doing its job .
Engineered wood is just timber traders trying to get the most out of a fast grown tree / the rubbish they cant sell . I used it once for some doors and the whole batch turned up warped .
Accoya has been pushed by the timber traders for about 8 maybe 10 years now as the new thing
It lasts 50 years they say but it wasnt used 50 years ago so i can only guess it doesn't last that long .
Iroko . Nice stuff , poor mans teak . It has an oily touch and thats what you want for durability .
Oak . King of woods .
Both of these you would want to stain and not paint .
Sapele . I use this for exterior cills if i'm asked for hardwood and also my choise if hardwood painted windows are asked for . Meranti and luan (sp) are from the same family but not as durable .
Jeldwin windows . shoot ! Mass produced storm proof joinery that relies on glue to hold the joints together and has channels directing the water to the joints
Personally i make my stuff from unsorted redwood . Its kind of worked for a very long time so why change it
