Enviroshake® is recommended for roofs with a pitch of 4/12 or greater. Please consult Technical Support at 1.866.423.3302 or info@enviroshake.com if your roof slope is less than 4/12.

The exact composition of Enviroshake® is a proprietary trade secret. It is what is commonly known as a composite material that contains plastics, fibers, and tire derived rubber. There are also components that protect it from UV degradation and provide the necessary colouring to replicate the look of cedar shakes.

No they do not. Standard shingles tend not to last as long on unvented sheathing; ventilation should be provided on solid sheathing for the best results. Please consult the CSSB's New Roof Construction Manual for more information.

Enviroshake® is currently offered in only one colour. It starts out as a brownish grey colour and converts or “weathers” to a silver-grey colour that closely resembles a real cedar roof.

Different jurisdictions have different code regulations but generally speaking, Enviroshake® can be installed over one layer of existing asphalt shingles, provided the roof is structurally sound underneath. There is considerable cost savings since there would be no additional cost for removal and disposal of the shingles. There are considerable environmental benefits to this as well because the old shingles need not be put in a landfill. No.

Slope is defined as the change in height (rise) as compared to the distance up the roof area (run) and is measured in inches. For example, a slope of 4:12 means 4 inches of rise for every 12 inches in run. Some people call slope "pitch", but the technically correct term is "slope".

Yes, placing a slope, driveway or building behind a wall is referred to as placing a surcharge or load on the wall. A maximum of a 2 to 1 slope can be placed behind a wall. Parking lots, driveways, buildings of all sizes even swimming pools can all be behind a retaining wall. The key to having a successful wall is making sure the wall is designed to meet the pressures (loading) that will be on the wall.

If AcreEase Wing Mowers are towed in tandem, they should not be used on slopes greater than 15 degrees because the back unit will push the front unit sideways. If the units are attached directly to the side of the tow vehicle, they are extremely stable on as much as a 40-45 degree angle. The Briggs & Stratton and Tecumseh Engines should not be used on angles greater than 25 degrees for any length of time because the engine will lose lubrication.

Deck: The structural surface to which the roofing or waterproofing system (including insulation) is applied. Flashing: Pieces of metal or roll roofing used to prevent seepage of water into a building around any intersection or projection in a roof, such as vent pipes, chimneys, adjoining walls, dormers and valleys. Granules: Ceramic-coated colored crushed rock that is applied to the exposed surface of asphalt roofing products.

APP (Atactic Polypropylene): A modifier of asphalt (see modified bitumen roof membrane) that increases the UV resistance of the bitumen as well as its flexibility at low temperatures and improves its flow resistance at high temperatures. Built-Up Roof (BUR): A flat or low-sloped roof consisting of multiple layers of asphalt and ply sheets. Base Sheet: A saturated or coated felt installed as the first ply in some multi-ply modified bitumen roofing assemblies.

For the receiver once it drops below 4.8V then do not fly it. This is for a 4 cell nicd pack. For the radio, 8 cell nicd, the alarm on it should go off once it goes below 9.6V. I do not have any personal experience with the use of these type batteries in the r/c hobby. The best place to find accurate information is R/C Battery Clinic. At this time I know of some issues with these packs. Li-Ion has an open type failure mode compared to the short type for nicd.

I-70 in CO near the west portals of of the Eisenhower Memorial Tunnel (MM 213-215) under the Continental Divide east of Dillon is 11,192 feet above sea level. (Map: 39.68,-105.93 ; see also http://www.dot.state.co.us/eisenhower/ and http://www.mesalek.com/colo/i70.html ) The second-highest is also on I-70 in CO at Vail Pass (Exit 190) which reaches an elevation of 10,666 feet above sea level. (Map: 39.53,-106.22 ; see also http://www.mesalek.com/colo/i70.

The lowest standard used to calibrate an assay is usually the lowest value you can report. Rarely, the manufacturer may validate an assay outside the standards. If this is the case, the lab must verify this, usually by obtaining additional standards.

The slope of the high-pass filters are 6 dB/octave. Each channels high-pass filter is continuously variable over a range of 80 Hz to 240 Hz. Individual channels are always assigned to the master bus - there is no provision to unassign an input from the master bus. However, direct outputs are post-trim, pre-fade. Because of this you can have the fader all the way off, and still ride that channel’s gain sent to the direct output with the trim level.

The two broad categories of asphalt roofing systems for commercial, industrial and institutional buildings are Built-Up Roofing (BUR) and Modified Bitumen Systems (MBS).

Slope soaring is flying a radio-controlled glider in lift that is created when wind hits a slope or near-vertical cliff. As the air hits the slope it is deflected up. Flying a model in slope lift is very similar to what hang-glider pilots do when the jump off cliffs and fly. With a stiff breeze and some experience, a slope-glider pilot can stay aloft for hours, all without benefit of an engine.

The Laser Grader can operate via laser control on slopes from 0 to 10% and can be operated manually on slopes up to approximately 25%.

Slope is the ratio between horizontal and vertical distance from the top of the levee to the toe. For example, if for every 2 feet of horizontal distance the levee is 1 foot lower, then the slope is 2 to 1.
