The thickness of blown in or sprayed roof/ceiling insula- tion (fiberglass or cellulose) shall be written in inches (min) on markers that are installed at (east one for every 300 square feet (28 m throughout the attic space. The markers shall be affixed to the trusses or joists and marked with the minimum initial installed thickness with numbers a minimum of 1 inch (25 mm) in height. Each marker shall face the attic access opening. Spray poly- urethane foam thickness and installed R -value shall be listed on certification provided by the insulation installer. 102.1.2 Insulation mark installation Insulating materials shall be installed such that the manufacturer's R -value mark is readily observable upon inspection. 102.1.3 Fenestration product rating. U- factors of fenes- tration products (windows, doors and skylights) shall be determined in accordance with NE' ii . .. . - d, independent laboratory, an labeled and certified by the maniac Products - lacking such a labeled U- factor shall be assigned a default U- factor from Table 102.1.3(1) or 102.1.3(2). The solar heat gain coefficient (SHGC) of glazed fenestration products (windows, glazed doors and skylights) shall be determined in accordance wit1_NFRC 200 by an accredited, independent laboratory, and labeled and certified by the manufacturer. Products lacking such a labeled SHGC shall be assigned a default SHGC from Table 102.1.3(3).

(Date APR 0 102.2 Installation. All materials, systems and equipment shall be installed in accordance with the manufacturer's installation instructions and the International Building Code. 102.2.1 Protection of exposed foundation insulation. Insulation applied to the exterior of basement walls, crawl - space walls and the perimeter of slab -on -grade floors shall have a rigid, opaque and weather - resistant protective cover- ing to prevent the degradation of the insulation s thermal performance. The protective covering shall cover the exposed exterior insulation and extend a minimum of 6 inches (153 mm) below grade. 102.3 Maintenance information. Maintenance instructions shall be furnished for equipment and systems that require pre- ventive maintenance. Required regular maintenance actions shall be clearly stated and incorporated on a readily accessible label. The label shall include the title or publication number for the operation and maintenance manual for that particular model and type of product. i—' SECTION 103 ALTERNATE MATERIALS — METHOD ____OF.GeNSTRUCTION, DESIGN OR INSULATING SYSTEMS 103.1 General. This code is not intended to prevent the use of any material, method of construction, design or insulating sys- tem not specifically prescribed herein, provided that such con- struction, design or insulating system has been approved by the code official as meeting the intent of this code. 103.1.1 Above code programs. The code official or other authority having jurisdiction shall be permitted to deem a Tl national, state or local energy efficiency program to exceed 4 4'! ( the energy efficiency required by this code. Buildings approved in writing by such an energy efficiency program shall be considered in compliance with this code. SECTION 104 CONSTRUCTION DOCUMENTS 104.1 General. Construction documents and other supporting data shall be submitted in one or more sets with each applica- tion for a permit. The code official is authorized to require nec- essary construction documents to be prepared by a registered design professional. Exception: The code official is authorized to waive the requirements for construction documents or other support- ing data if the code official determines they are not neces- sary to confirm compliance with this code. 104.2 Information on construction documents. Construc- tion documents shall be drawn to scale upon suitable material. Electronic media documents are permitted to be submitted when approved by the code official. Construction documents shall be of sufficient clarity to indicate the location, nature and extent of the work proposed, and show in sufficient detail perti- nent data and features of the building, systems and equipment as herein governed Details shall include, but are not limited to, insulation materials and their R- values; fenestration U- factors and SHGCs; system and equipment efficiencies, types, sizes
