Vinyl Siding

Length of panels	Can be as long as 40 feet	12 - 12 1/2 feet is average
Width	6 1/2 to 10 inches
Applicable Standards	ASTM E119	This means that the fire endurance ratings are similar to walls without vinyl. For example, having vinyl siding doesn't speed up a fire.
Applicable Standards	ASTM D3679	Means that the vinyl at least met the established requirements for the methods used to test the material, dimensions, expansion, appearance and windload resistance.
Thickness	Optimum panel thickness is between .038 and .48 inches. Thicker, rigid panels provide better wind resistance, protection against damage, and lay flatter and straighter.
Panel Projection	The amount the panel sticks out from the side of the home.	Look for the maximum projection for the style of vinyl selected.
Chemistry	Look for a high concentration of titanium oxide.
Formulation	High temperature fusion and after formulated manufacturing methods result in stronger panels.
Windload Pressure	The amount of wind pressure the panels can take before coming off or breaking	Look for a negative windload pressure, it gives a truer picture of windload pressure than a positive test.

HardBoard

Thickness	1/4 to 1/2" nominal	Min-Max .22 to .525
Thickness Swelling	8%	Maximum average per panel
Water Absorption	12%	Based on the maximum average weight of panels
Edge Straightness	Shall not exceed 1/64 inch from corner to corner on same edge
Applicable Standards	Model building codes all over the US	Recognized
	ANSI product standard	Conforms
	American Hardboard Association	Certified
Maker may be indicated on the back of the board using these numbers	AHA01	Boise Cascade - MN
	AHA02	Weyerhauser - OK
	AHA03	Temple - TX
	AHA 04	Louisiana Pacific - NC
	AHA 05	Forestex - OR
	AHA06	Masonite - CA
	AHA07	Georgia Pacific - SC
	AHA08	Masonite - CA
	AHA09	Evanite - CO
	AHA10	Weyerhauser -OR
	AHA11	Millian Blodel - Ontario
	AHA12	Masonite - PA

Cedar Shakes and Shingles

Applicable Standards	Cedar Shake and Shingle Bureau	The only shake and shingle association listed by name in all US Model Building Codes
Applicable Standards	Cert-label	Only Certi-Labeled products have been inspected and meet the standards for quality, material, packaging and shipping.

Brick

Thermal Mass	The ability of a heavy, dense material to store heat and gradually release it	House stays warm in the winter and cool in the summer
Sizes	There are 12 sizes of brick; each given a name by the US Brick Manufacturers, these names are commonly used in the industry	Modular, Standard, Engineer Modular, Engineer Standard, Closure Modular, Closure Standard, Roman, Norman, Engineer Norman, Utility, King, Queen
Units	Clay and shale units can be made in various sizes and shapes and are either hollow or solid, more than one type of unit can be used in an application
Further Information	Brick Industry of America	There are too many types of shale and clay, variety of units that can be used in combination and the sizes of the bricks for a chart of this type.

Aluminum

Thickness (dry film)	.80 to 1.00 millimeters	Min-Max .22 to .525
Applicable Standards	Aluminum Association	Created a 4 digit numbering system, each number represents a different aspect of the aluminum
	There are many standards associated with the many different aluminum alloys; examples are:
	D714	After 3000 hours in 100% relative humidity there is no loss of gloss, no cracking or peeling
	D2244	Shall not fade more than 5 color units in 5 years after all dirt has been removed
	ASTM B117	Can withstand 5% salt fog for 3000 hours
Temper	Temper is the term for the hardness or toughness of aluminum	Tempers describe how the aluminum will be processed and follow this designation system. F- Fabricated O- Annealed H- Cold rolled and strain hardened W - Solution heat treated T- Thermally treated
Chemistry	Melting Point	660° C The aluminum for siding is combined with another metal such as copper to give it strength

I. Importance of Siding — Protection of frame from the elements and pests, health i.e. mold

II. Styles of Siding — clapboard, shingles, shakes

III. Materials used in Siding — Pros and Cons of the many materials: vinyl, cedar, aluminum etc.

IV. Siding maintenance — power washing, denting, painting

V. Siding Rating Systems/ Specs — profile, thickness, windload resistance
