don't suppose anyone knows of a bowstring truss calculator or anything? 🤣

sorry, yes, I meant as in supporting a small mezzanine floor!

OK, I’m wondering if this is even possible there, so please bear with me on this… not a huge span (4.500mm), the max depth in the centre is around 360mm, and the max depth at the ends of 115mm. Would this be possible?

OK, to make things easier if anyone is interested, you can follow progress here… https://www.smallmissionhall.com/

True, I’m just not a fan of plasterboard as a surface finish. I’m the 0.01% who wants something else 🤣

I will try Envirograf again, as I haven't heard back at the moment.

Don’t suppose you still have their details to ask? 🤣 Just enquiring about 9mm Magply Euroclass A1 Non-Combustible Board 2400 x 1200mm as an option

No joy as yet, the issue seems to be that Building standards require 30 min fire resistance, primarily because I hope to have a small mezzanine floor area for sleeping, which so far, no manufacturer can apparently meet. Struggling to find a viable alternative to plasterboard, which I would like to avoid if at all possible (single-use product, non-reusable or repurpose and you have to pay to dispose of it)

Thanks, I’ve just got in contact with both so I’l see what they suggest?

Hi, I’m looking into using Intumescent paint for use on OSB as an internal wall finish that needs to be fire-rated in Scotland. Can anyone recommend a supplier whose product has accredited data from an independent body such as BBA or BRE to verify that the paint product would achieve the required fire resistance on OSB sheeting?

Water for porridge only when I run out of milk – I'm not a fan of salt in pretty much anything, apart from Fish and Chips obvs!

So far so good with the electricity

That's for softies!

Ah, is that what they are called, an unvented water heater? Helpful to know what to search for in the first instance!
