hi everyone
 
	 
 
	I have joined the forum in the hope that you erudite folk can help a hapless diy'er/consumer help make some informed decisions on material choices.
 
	instead i have jumped feet first into a garden structure - thinking it was the way forward.
 
	 
 
	i purchased a light gauge steel frame that is sat on ground screws - this was due to an undulating lawn and a some pretty big tree stumps and roots that wouldn't have allowed a base
 
	 
 
	so my first problem is - how am i going to insulate the floor on this damn thing -  as due to its construction,, i cannot get any PIR boards to get a tension fit , i cant get any mesh underneath to prevent rockwool from falling out due to the brackets that it sits on.
 
	 
 
	my uncle said as i will not be in it 24/7 - there is no need to bother ??
 
	 
 
	any ideas or suggestions please 
 
	 
 
	many thanks in advance and apologies for such daftness
