Hi there people.
just want your opinions on the best method of applying sidewall shingles. regarding furring strips and stuff like that. i’m living in ireland and we’re regarded as a mixed climate, approx. 30″ rain per annum, felt or tyvek, stuff like that.
what do you lot think?
thanks and good luck!!
Prescriptive codes don't address the connection at less common angles, so base the connection off more typical ones using bolts, structural screws, blocking, and steel tension ties.

eddie, Usually I do not use furr strips under my shingles, but a good many of my shingle jobs are using board sheathing. For plywood sheathing I have installed directly to the plywood and over furr strips ( 1/4" wood lath ). I have not detected any major problems with either way, but the walls are under 15 years old.
In either case I prefer using red rosin paper as first choice, 15# felt as second choiuce, newspaper as third choice. I do not like nor recommennd using the housewrap, especially under cedar or cementious siding.
The rosin paper and felt work quite well as wind paper, which is superfluous if using plywood for sheathing and blocking all joints. As a weather barrier, the better wicking ability of the paper allows moisture to disperse over a greater area and evaporate more quickly thus reducing the potential for water damage.
Also use a 5d galv. box or shingle nail, two per shingle

There was a great article on this a while back. Is it new construction? The best case set up is to use whatever barrier you want on the home before trimming. then install strapping(1/2 inch pressure treated ply ripped to 2" lets say) vertical along wall studs on top of sheathing and barrier. Then install 3/4 x 2 "or better horizontal on top of those. Then back prime and install shakes to your strapping . Make sure you figure all that into your trim and window requirements. A piece of venting (coravent strip) with screen attached installed at the bottom keeps out bugs but allows water to flow freely out the bottom from behind siding. This system is great for letting the shingles dry out quickly gets the most life from the shakes and whisks water out quickly when it gets where it should not.
