Vinyl siding renovation
I have a 40 year old home in Canada (Toronto) with about 75% of it covered in aluminum siding, black paper, exterior gypsum, 2×4 wall as with kraft faced Batts and interior gypsum. I am having this replaced with a thick residential VinylSiding. I am debating on what to put under the siding. Do I leave the tar paper on for its absorption and drying abilities…or do I get Tyvek installed? The contractor also has a 3/4 inch permeable polysio insulation called IKO enerair. Apparently this is an insulator and an air barrier. I would like some advice on what I should do. Thanks for your help.
