Noggings

ozdemirozgur

Hi,


I would like to strengthen the existing joists in my shed roof by putting some noggins between them. Existing joists are 2x3, and I will use the same for noggins. Can anybody let me know whether I should use screws or timber nails to fix noggins to the joists.

I always use screws, they are slightly easier to drive in and grip/hold in. 100mm No 6 should be fine.

Normally I would use nails ( for noggins) , but as you are fixing above your head and near a cheap thin roof, would in your case a few screws seems reasonable.

Noggins won't strengthen any joists, but will make the construction more rigid - is this what you mean you want to do??

If so - then +1 with Phil - pilot hole thru the joist too.

Hi,


what is a pilot hole? checked on internet but was able to find to many information.

You drill a narrower hole than the screw you're going to use, prevents the wood from potentially splitting.

Completely agree with all the posts above.

As your joists are only 2" x 3" I would use screws. As already mentioned above the noggins are to make the structure more rigid by preventing the joists twisting.

The pilot hole made by a 4mm wood drill bit will not only prevent the joist from splitting but will save you a lot of effort in screwing the noggings.

How far apart are your joists?

There is not standard between joists. min 50 cm up to 80 cm in some cases.

My suggestion is to do three lines of staggered noggins.
