A quick look on the Sabrefix website suggests that Builders Band is 1mm thick ! Whereas 'Restraint straps' appear to be available in 2.5mm and 5mm. For the straps to bridge the first 3 joists, they would have to be 1600mm. The restraint straps idea seems more robust, but is it...

I see what you are saying. Would the BCO be likely to sign off floor boards being used as the binders? What dimension would binders normally be? On a similar note though, is there a metal strap or special hanger that could be used at the perpendicular joint where the short joists attach to...

Linked to my other post about rafters and joists, but slightly different ................ A neighbour has just had an extension built, very similar to the one that I am doing, and I grabbed the chance to climb up the scaffolding and have a look at how the builder constructed the roof. He...

I thnk you mean 1/3 longer? 148" would = 199"

Richie Start a new thread! This one is 18 months old ! For what it's worth though Aircrete blocks are no where near as weather resistant as concrete blocks, and they pull the moisture out of plaster/render very quickly so I should imaging that they are harder to render and that the...

Thanks for the input. Just for closure - I went ahead and installed them, and the BCO was happy with everything when he inspected it. Cheers Gary

Guessed what? Sorry I don't understand what you are saying.

Not at all noseall ! But like I said - I need to get scaffold in to finish the gable end and tile the roof. If I need to get it in earlier I will, but the budget is too tight for me to have the it sitting unused for 5 days a week. My intention all along has been to cut the roof, and do as...

Well the clear span is about 6.8m and so including overhang that is approaching 8m. And with this being a DIY job over many weekends, I haven't got scaffolding - Everything is being done from the inside out - So lifting them into place would be a nightmare. I am going to have to get...

Cheers Oldun. 2 more questions then ................ Firstly, how do roof trusses compare price wise to cutting a roof on site? Secondly, how on earth do you get them up and into position ? Cheers Gary

All I am in the process of designing the roof construction of my extension, and I need some advice regarding what is and isn't acceptable. The extisting roof has got 2 big purlins in it, at roughly half height. That space will be staying as loft storage, but the loft space of the extension...

Use the HTC to measure a known angle, before you rely on it. I've got an HTC desire, and used it to measure my Rafters. They came in at 35 degrees. Smart phones are great, but make sure you understand the callibration. I trusted the phone GPS with Endomondo to measure the distance I ran...

A quick joist hanger question for you .................. Can I use 50mm joist hangers to hang 47mm regularised timber joists? I wrongly purchased 50mm hangers, and really need to do the job this weekend, which means that I won't be able to get back to the builders merchant to swap them...

Joist hangers are metal shoes that can be built into the wall, and then the joist sits in the metal cup that hangs out from the wall. Joist Seals are rubber seals that you can use to seal the gap if you opt for building the joist into the wall. Joist seals seem like a great idea, but thay...

Please tell !

Sorry, another joist related question from me............... When I build a joist into a new wall, how do I actually do it? My plan is for the joists to sit directly on top of a course of blocks, and then the other end will be on a joist hanger attached to a ledger board. I will take the...

I'm using the Trada ones, but wasn't sure about the loadings, so opted for the 0.5>1.25 column rather than the <0.25 Saying that though, the joists seperate a garage and a bedroom, so I want maximum depth for Sound and Heat insulation. Good point How does the price compare?

I am thinking of stepping up to 47mm Joists, and increasing the spacing to 600mm from 450mm. Joists are the same price per metre regardless, so why pay for 6 more than necessary

Just had a quote from the builders merchant, and the price per metre is the same regardless of 47mm or 38mm. So the 600mm spacing immediately works out £65 cheaper

Plenty of people have boarded lofts with lights and power up there, I think that it all depends on how 'Official you want to make it, and what you want to use it for. I have got a boarded loft, and my boys have their scalextric set up up there. You should only need planning permission if...
