102.1.1.1 Blown or sprayed roof /ceiling insulation.
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).

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.

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
