Doors the hob need ventilation underneath? Fans and cooling? If so, higher is better. Easier seal against an edge too. Though I get the aesthetic appeal of flush.
The rain held off enough, so I was able to get it finished. I've also started to glue them in. I drive a screwdriver level into the side, and squirt PU into the gap.
I think it will work. Next step after the glue, is the anti mouse mesh.
It's only friction fit. But as in hammered in using a wooden batten as a drift. I'd not walk on it, but it's tight. Still tempted to put a shot of PU expanding foam in each corner.
There IS an air gap between the frame and the insulation - to allow the steel to dry out if it does get wet.
Ideal for mouses. Not sure what to do about that. Stuff with stainless wire wool?
It's a consideration. Not getting a cat, no more pets, but dunno.
I've a plan for the insulation. Fit the panels tightish, but cut the corners off. Not much. Size of a pen. And squirt expanding foam into. Should lock it in place nicely.
This is getting to the stage where it's almost indoors, and needs to be kept clean as well as tidy.
I'm hoping to get a good start on the insulation tomorrow. Weather permitting.
Not sure exactly how I'm going to suspend the insulation between the joists, but I expect I'll think of something.....
That's exactly the plan, just popping next door to get some timber.
This won't win prizes for neatness, but should stop the creosote seeping through the breathable membrane.
I do understand your concern. The welds are holding it up.
Anyways, three of the noggins were too long, I forgot that three joists were needed for the middle. So I had to cut an inch and half off all three.
I'm impressed at how effectively the creosote wicked up the boards.
Off to get the...
Well, there's nine of them, and eighteen welds. Each weld is four inches long.
The cross pieces are not light. Can't remember off-hand, but 90*8 mm rings a bell. Chunky enough.
Even with my welding, that's enough to support the weight of the structure, which wouldn't be more than 4 ton.
The wooden joists? No. The whole thing is resting on the steel cross pieces. Which rest on the sleepers.
The floor boards will be secret nailed to the wooden joists, but will be isolated from the creosote with a DPC of some sort, either actual DPC or visqueen DPM.
Ran out of batteries, light, roofing bolts, creosote, energy just as the last joist went in.
I'll check everything tomorrow, but for the most part it feels very, very solid.
One or two bits didn't feel entirely bomb proof, so I might get inventive with the 3*2 bits of surplus. Depends.
