Engineered timber

[hibbo]

Hello everyone,

I am thinking of starting to use engineered softwood for my doors and windows and would like to know if it stable on external joinery, and if anyone has come across any problems while using it as i have been told it is very good but would like to hear your opinions.
Many Thanks.

I remember at Richard Arnolds open day him talking about a new type of treated softwood being used to window joinery that was almost indestructible from rot etc, but cannot recall what it's name was.

can anyone shed some light?

Accoya. Tricoya.

Accoya. Tricoya is MDF treated in same way. 50+ years unfinished IIRC

Good quality pine heartwood lasts just as long and oak heartwood even longer........ I just find it wrong that the logging companies churn out fast grown krotty rot prone wood of worse and worse quality and force people to use artificial substitutes for the real thing.

I used engineered timber for some external doors and frames I made a few weeks ago. Was for an architect so wanted to get it right.
Was end jointed 3 layered laminated redwood. Came in perfectly straight 6 meter lengths.
cant say that it will last longer than unsorted redwood, will let you know in 50 years time !
Will definitely use again, not much more than unsorted red either. Machined and painted well and seemed very stable with no knots, faults etc
Agree with you about softwood heimlaga. I wish I could bring some real northern pine to show people in the uk. No comparison with the firewood that ends up in the UK.
