Vinyl Siding

Length of panelsCan be as long as 40 feet12 – 12 1/2 feet is average
Width 6 1/2 to 10 inches
Applicable StandardsASTM E119This means that the fire endurance ratings are similar to walls

without vinyl. For example, having vinyl siding doesn’t speed up a fire.

ASTM D3679Means 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 ProjectionThe 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 PressureThe amount of wind pressure the panels can take before coming off or breakingLook for a negative windload pressure, it gives a truer picture of windload pressure than a positive test.

Cedar Shakes and Shingles

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


Thermal Mass The ability of a heavy, dense material to store heat and gradually release itHouse stays warm in the winter and cool in the summer
SizesThere are 12 sizes of brick; each given a name by the US Brick Manufacturers, these names are commonly used in the industryModular, Standard, Engineer Modular, Engineer Standard, Closure Modular, Closure Standard, Roman, Norman, Engineer Norman, Utility, King, Queen
UnitsClay 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 AmericaThere 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.


Thickness (dry film).80 to 1.00 millimetersMin-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: 
D714After 3000 hours in 100% relative humidity there is no loss of gloss, no cracking or peeling
D2244Shall 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
TemperTemper is the term for the hardness or toughness of aluminumTempers 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

ChemistryMelting Point 660° C

The aluminum for siding is combined with another metal such as copper to give it strength
