Wood
Once the leading siding material in the nation, wood was, of course, the material of choice for early settlers. Wood is still a popular siding in new home construction, but the high cost of repainting and wood's tendency to deteriorate over time have caused nearly all the re-siding market to convert to non-wood products. As wood prices have risen due to environmental protection harvest restrictions, wood is being used less frequently as a siding material in new construction.
Polypropylene
The most recent addition to CertainTeed's extensive line of vinyl building products, Cedar Impressions� Perfection and Half-Round Shingles and Rough-Split Shakes are manufactured from a specially blended polypropylene copolymer. This copolymer capitalizes on the rigidity, weatherability, and processing properties of polypropylene
and other micro-ingredients. Unlike our PVC siding, which is extruded, polypropylene Cedar Impressions� is injection molded into its authentic cedar shingle patterns.
The Siding Collection is a total package approach to exteriors. It begins with an unsurpassed selection of siding profiles, each designed for architectural accuracy and superior performance. Then we add expansive trim options, decorative details, and color choices, all of which work together to give each home a unique look.
Cedar Im
pressions� Rough-Split Shakes
Cedar Impressions� is CertainTeed's super premium siding. Cedar Impressions is a family of cedar style shingles available in three styles: Perfection Shingles, decorative Half-Round Shingles, and Rough-Split Shakes. Used on the whole house or as an accent, any one of these products provides dimension and texture to any home,
and they will not rot, crack, split, or cup like real wood shingles.
Real Wood Appearance
It's almost impossible to tell the difference between a real cedar shingle and Cedar Impressions. To underscore how remarkably similar Cedar Impressions� is to its wood
Counterpart, consider how the product is made. Real cedar shingles are used to create rubber molds. The pattern is transferred onto a set of molds from which the Cedar Impressions panels are created.
Unique Construction
Cedar Impressions� Perfection and Half-Round Shingles and Rough-Split Shakes are suitable for just about any climate.
Thicker than standard lap siding and molded with color clear through, Perfection and Half-Round Shingles have a 3/8" panel projection, while Rough-Split Shakes has a 1" panel projection.
The high butt leg provides rigidity over the length of the panel as well as a distinctive shadow line. Molded ribs on the back of the panel provide
structural stability to help prevent warping and distortion. Unlike lap siding, Perfection and Half-Round Shingles and Rough-Split Shakes have a molded perimeter locking
system which does two things: It gives the installation a virtually seamless appearance from top to bottom, end-to end, and it enables the product to withstand high wind
load pressures. This accounts for the products' popularity in the coastal, hurricane-prone states.
Distinctive Designs
Cedar Impressions is recommended when design is important because its three styles offer the possibility to achieve a distinctive look. Cedar Impressions Perfection and Half-Round Shingles and Rough-Split Shakes are injection molded with durable polypropylene.
D7 Perfection Shingles are 48" long with a 14" exposure. T5 panels are 60" long with a 15" exposure.
They are .100 in. (nominal) thick and extra rigid. Ribs on the back of the panel add structural stability, while the molded perimeter lock creates a seamless look and holds
panel securely together.
Half-Round Shingles are often found in gables, under windows, and on other areas of the home where the design calls for highlights. Available in 32 in.-long panels in a double-course pattern, Half-Round Shingles features a 12-1/2" exposure.
Rough-Split Shakes are designed for whole house coverage or accent areas. With its designer color palette and rustic split-cedar dimension, this 57-in.-long panel
has an 18" exposure. The thickest siding on the market, homeowners prefer Rough-Split Shakes for its superior strength and rigidity.
Designability
Like wood shingles, Cedar Impressions� styles can be interchanged to create a unique, decorative effect. Also, all three styles can be installed with lap siding for a
custom look.
Finally, Cedar Impressions� styles can be installed with ordinary siding accessories, including wide decorative trim that resemble the lumber trim found on the most expensive, wood-shingled homes. These accent pieces, or lineals, are available in 3-1/2 in. and 5 in. widths to resemble 1 x 4 and 1 x 6 boards. When the job is completed, these lineals look like traditional wood carpentry. Mitered Cornerposts are available for Perfection Shingles and Rough-Split Shakes.
When installed with nails, Cedar Impressions� D7 Perfection Shingles have been tested to withstand negative wind load pressures up to 85 psf, which
converts to 180 mph.
