I am planning to winterize the patio, 4 x 10 m, raised 1.4 m above ground level in the same level as the lower floor. Currently only clapboard and three window sections 1.4 x 2 and a sliding door section 2 x 4.
Built in 1990 with 100 x 20 pressure-treated decking on the floor. Roof made of tile-like sheet metal and 5 insulation MDF boards as the ceiling.
Thankful for suggestions.
Best regards,
Roffan
