Carpentry

Attach stainless steel screening over the 2 triangular ends of the attic to prevent squirrels, etc from entering. I have 196' screen rolls 39" wide. Need the 3/4" plywood floor finished all the way around edges of attic floor. Center of the attic floor is done. Must fin approx 4' all the way around. Attic is approx 24'X40'. Ceiling center pitch is approx 10'. I’ll purchase the 3/4" plywood to finish floor. Actual measurements needed.
