Porch is progressing well out front. Timber frame of '6x2's to walls has been infilled with Rockwool Flexi, with 140mm Rockwool Frontrock Max E Dual Density (DD) slab providing the tea cosy. Solitex Fronta Quattro membrane is used for the outside wind tight layer for it's suitability with open jointed cladding. All held on by vertical battens screwed through the DD slab to the studs. It's rock solid, unlike the original porch.
On the roof is 300mm Rockwool Flexi between the Larsen truss type beams, topped out with 60mm Rockwool Hardrock. U-value for wall and roof=0.12 W/m2K.
