Every new residential dwelling structure or any new addition to a dwelling structure shall have properly installed thermal insulation with the following R/resistance factors based upon the building section in which it is installed.
Building Section
R/Resistance Factor
(a)    Exterior Walls.
(1)    Frame walls
(2)    Masonry walls above the frost line, including walls in living areas and basements
(3)    Other fabricated exterior walls above grade
(b)    Ceilings.
(1)    Conventional horizontal ceilings under ventilated attic spaces
(2)    Cathedral ceilings with conventional interior finish, which shall have insulation between roof rafters
(3)    Cathedral ceilings with exposed beams and roof sheathing for interior finish, which shall have built-up roof insulation
(c)    Floors.
(1)    Frame floors over unheated areas
(2)    Slab-on-grade floors which shall have insulation at their perimeter
         Such insulation shall be:
         A.    Installed vertically from the top of the slab floor to below the frost line around the perimeter of the slab; or
         B.    Installed vertically from the top of the slab floor, extended down the thickness of the slab and continued horizontally back under the slab to a width of at least two feet around the perimeter of the slab floor.
      (3)    Heating/cooling ducts that are installed in slab floors shall be enclosed by the warm winter side of the perimeter insulation in the manner provided in subparagraph (c)(2)B. hereof.
   (d)    Windows.
      (1)    Windows, including basement windows, shall be double-glazed or installed with storm windows.
      (2)    Metal windows shall provide a thermal break between the inside and outside surface areas.
   (e)    Doors.
      (1)   Doors shall be insulated with an insulation core; or
      (2)    Doors that are uninsulated shall be installed with storm doors.
   (f)    Caulking and Sealants. Exterior joints around windows and door frames, between walls and foundations, between walls and roofs, between wall panels, at penetrations of utility services through walls, roofs and through floors over unheated spaces, and all other openings in the exterior envelope of such dwelling structures shall be caulked, gasketed, weatherstripped or otherwise sealed to prevent air leakage.
   (g)   Vapor Barriers.
      (1)    All insulation shall be installed with vapor barriers, rated one perm or less, on the warm winter side of such insulation, provided, however, that vapor barriers shall not be required for top-ceiling areas that meet the attic ventilation provisions of Section 1529.11 of the Regional Dwelling House Code or applicable provisions of the Ohio Building Code.
      (2)    Slab floors in living areas and slabs in crawl- space areas shall have vapor barriers rated four mil thickness with maximum one perm vapor penetration installed beneath the slab.
   (h)    Installation. Insulation shall be installed in building sections in a workmanlike manner in order to receive the thermal insulation effectiveness of the R/resistance factor designated by the manufacturer on his product.
      (1)    Insulation on all side walls shall be firmly packed without exposures, at both the top and bottom wall cavities.
      (2)    Insulation shall be chinked into all rough windows and door frame openings and covered with a vapor barrier.
      (3)    Batts shall be neatly stapled at least every six inches.
      (4)    Vapor barriers shall not be damaged before the final wall finish is installed.
   (i)   Inspection. All work involving the installation of insulation subject to the insulation requirements and installation standards and requirements established by this section shall be inspected by the Inspector of Buildings before concealment.
   (j)   Controlling Provision in Conflicts. In the event of a conflict between any of the provisions of this section and a provision of the Regional Dwelling House Code adopted in Section 1331.01, a provision of the Ohio Building Code adopted in Section 1341.01 or a provision of any other applicable ordinance or code adopted by the Municipality, the more restrictive provision shall prevail.
