Thanks Jeebus and LiquidSV.

Hey guys - they didn't teach us girls CDT like they did the boys... Nobody's forcing you to read my posts if you don't want to :-)

What's CDT? (genuinely)

You've obviously been taught more about it than me.

Ahhh, we had Craft & Design, Technological Studies and Technical Drawing as three seperate subjects.

Sarah - by all means, ask any question you like.

My post was an attempt to point out that, in all honesty, monkeys learn faster than you! If your query relates to Homes/DIY etc, then you should start your thread in the Homes/DIY forum. (Most people realise this after the 3rd or 4th time).

I'm really starting to sound like the 'milk monitor' at school here, aren't I? boxedin

It seems they're both treated, so what's the difference between these two types of timber?

I'll try to keep it simple...

Firstly, generally they're not both treated.

Carcassing is a lower grade of timber, usually faster grown with wider growth rings (grain) & larger knots that is used for studwork, joists etc. It can be treated or untreated depending on where its being used & generally comes kiln dried to stop shrinkage. Its often strength graded to C16 or C24 grade, C24 being the better one of the two.

PAR, as mentioned means planed all round (smooth) & is of a higher quility that is used for joinery work. There are several grades of PAR timber but most merchants stock fifth Scandinadian or fourth Russian redwood, some stock unsorted joinery which is a higher grade with smaller knots & a straighter/tighter grain. This can also be treated but its a different kind of treatment to the one used on carcassing, its uncommon to find treated PAR timber in stock anywhere. PAR timber is also kiln dried but to a lower moisture content than carcassing.

Theres lots more to it than that, but hopefully that tells you enough.

If not, employ a builder...its what they do biggrin

Was being serious, by the sounds of you posts you need a copy of

you may get more serious answers posting DIY questions in the Homes section rather than the mods having to move them though wink
