prefabricated

assemblies

shall

be

CHAPTER 16 Plastics

SECTION 1601. Approved Plastics . — Approved plastic

materials shall be those which have a flame-spread rating

of 225 or less and a smoke density not greater than that

obtained from the burning of untreated wood under

similar

conditions

when

tested

in

accordance

with

generally accepted engineering practices. The products

of combustion shall be no more toxic than the burning of

untreated wood under similar conditions.

SECTION 1602. Installation . — (a) Structural Requirements

— All plastic materials shall be of adequate strength and

durability

to

withstand

the prescribed design loads.

Sufficient

and

substantial

technical

data

shall

be

submitted to establish stresses, maximum unsupported

spans, and such other information as may be deemed

necessary for the various thicknesses and forms used.

(b)

Fastenings

—

Fastenings

shall

be

adequate

to

withstand design loads and internal and external stresses

required of the assembly. Proper allowances of plastic

materials in conjunction with other materials with which

it is assembled or integrated shall be provided.

SECTION 1603. Glazing of Openings . — (a) Doors, sashes

and framed openings in exterior walls of all buildings

except Types IV and V Constructions may be glazed or

equipped with approved plastics: Provided, that:

(1) The wall in which such glazing is installed is so located

that openings are not required to be fire-protected.

(2) Except for Type I Construction, the location size, and

spacing of such glazed openings do not exceed the

values set forth by the Secretary.

(3)

Plastic

used

in

glazed

openings

for

Type

II

Construction

shall

be

materials

appropriate

for

use

according

to

flame-spread

characteristics

and

the

location, size, and spacing of the openings do not exceed

the values set forth by the Secretary.

SECTION 1604. Skylights . — (a) General — Approved

plastics may be used in skylights installed on roofs of

Types I, II, or III constructions and all buildings in these

categories shall be equipped with an approved automatic

fire-extinguishing system in Groups A, B, C, E, F, J, H-3 and

H-4 Occupancies: Except , that:

(1)

Approved

plastics

may

be

used

in

any type of

construction or occupancy as a fire venting system when

approved by the Building Official.

(2) Plastic may be used in approved skylights in Type II

one-hour fire-resistive construction which are located 300

millimeters or more above the lower place of the ceiling.

The walls of the skylight well shall be no less fire-resistive

than the adjacent ceiling.

(3)

Where

fire-resistive

ceiling

is

not

required

in

one-storey buildings, approved plastics may be used in

skylights.

(b) Installation Requirements . — (1) Except in Group A

Occupancies, no skylight shall be installed within 3.00

meters of a property line.

(2) The edges of dome-type skylights shall be properly

flashed.

(3) Plastic skylights shall be separated from each other by

at least 2.50 meters laterally and 3.00 meters along the

slope of the roof.

(c) Allowable Areas — The area of individual plastic

skylights shall not exceed 10.00 square meters. The total

aggregate area of plastics used in skylights, monitors, and

sawtooth glazing shall not exceed twenty percent of the

floor area of the room or occupancy sheltered.

(d) Curb Requirements — Plastic skylights in roofs having

a slope of less than 1 in 3 shall have a 100 millimeters high

curb. The curb may be omitted where a wire screen not

smaller than No. 12 U.S. gauge with a mesh not larger

than 25 millimeters is provided immediately below the

skylight. The screen shall be substantially mounted below

the skylight.

SECTION 1605. Light-Transmitting Panels in Monitors and

Sawtooth Roofs . — (a) General — Where a fire-resistive

rating is not required for the roof structure, and in all

buildings

provided

with

an

approved

automatic

fire-extinguishing system, approved plastics may be used

with or without such as the light-transmitting medium in

monitors and sawtooth: Except , that plastics used in

monitors or sawtooth roofs of Type II Construction shall

be of materials appropriate to be used according to

flame-spread characteristics.

(b) Allowable Area — The area of individual plastic glazing

used in monitors and sawtooth glazing shall not exceed

15.00 square meters. The total aggregate area of plastics

used in skylights, monitors, and sawtooth glazing shall

not exceed twenty percent of the floor area of the room or

occupancy sheltered.

(c) Area Separation — The area of such plastic panels

shall be separated from each other by a section of

incombustible material or by a section of the roofing

material of the structure not less than 1.50 meters in

length. The lower edge of the plastic material shall be at

least 150 millimeters above the surface of the adjoining

roof surface.

SECTION 1606. Plastic Light Diffusers in Ceilings . — (a)

General — Ceiling light diffusers having an area greater

than ten percent of any 10.00 square meters of room area

shall

be

of

approved

plastics

conforming

to

the

requirements specified in this Code.

(b) Installation — Plastic light diffusers shall be installed in

such

a

manner

that

they

will

not

readily

become

detached when subjected to room temperature of 80ºC

for 15 minutes, Except , for the plastic light diffusers which

are installed in the first floor area of Group C Occupancies

having egress directly to the exterior of the building; and

plastic light diffusers which are located between an

approved automatic fire-extinguishing system and the

area to be protected other than public corridors for Group

A, B, C, D, E, G, H and I Occupancies if tests required by

the Secretary have established that such installation will

not

interfere

with

the

efficient

operation

of

such

automatic fire-extinguishing systems.

SECTION 1607. Partitions . — Where partitions are not

required

to

be

of

fire-resistive

or

incombustible

construction,

approved

plastics

conforming

to

the

requirements specified in this Code may be used.

SECTION 1608. Exterior Veneer . — (a) General — Exterior

veneer may be of approved plastic materials, and shall

(b) Height — Plastic veneer shall not be attached to any

exterior wall above the first storey: Provided, that plastic

veneer may be attached to exterior walls above the first

storey of buildings located outside of highly restrictive

Fire Zones: Provided, further that the height of the veneer

is not in excess of 10.00 meters above the adjacent of

elevation.

(c) Area — Sections of plastic veneer shall not exceed

15.00 square meters in area, Except, that in less restrictive

(d) Separation — Sections of plastic veneer shall be

separated by a minimum of 1.20 meters vertically and 600

millimeters horizontally.

SECTION 1609. Awnings and Canopies . — (a) Plastic

materials appropriate for use according to Flame Spread

characteristics may be utilized in awnings and canopies,

provided such awnings and canopies are constructed in

accordance with provisions governing projections and

appendages as specified in this Code.
