SWMBO wants a new potting shed for her 40th birthday (shopping trips to New York, spa weekends, designer handbags are not her thing!) and we're getting tied up in knots trying to decide whether there are better options available to us by scouring the interweb.
There seem to be two areas of confusion for us - style of "cladding" and thickness of the cladding.
Some firms quote "overlap", some "shiplap", some "tongue & groove" and some "tongue & groove shiplap". I'm happy with "overlap" (plain boards, overlapping each other). I think I'm OK with shiplap (plain boards with a shallow section cut from opposite sides, so that whilst the boards can overlap the overall surface is more or less vertically flat). Its the "T&G shiplap" that I don't really understand. Can anyone enlighten me (and give me a good steer as to which is the most long lasting / preferable / sturdy).
Then timber thickness. There is a range (BillyOh) which appears to pride itself on the "strength" of the sheds. That uses 11mm timber (T&G apparently). Another local provider says it uses 16mm "T&G shiplap". Is it worth spending the extra on those 5mm?
Any other relevant info gratefully received!
Thanks
Matt
