Are the Pinehaven walls lined internally? All Pinehaven Sheds and Studios come stock standard with a heavy paper lining. Standard Courtyard Cupboards and Kids Cubbies do not come lined. For a small cost you can upgrade to fire rated building paper. By samr12| 2018-05-29T18:08:17+00:00 May 29th, 2018|0 Comments Share This Story, Choose Your Platform!
