Panels can be stored outdoors without suffering damage from rain or snow. However, panels must not be exposed to direct sunlight while they are stacked. Stacks of three or more panels act as a solar heat collector and may incur heat stress damage, which is not covered by warranty. Do not stack or place heavy objects on the panels.

Panels are lightweight, flexible and can be rolled up for easier handling. Long panels should be carried by two people, especially in windy conditions. If panels are to be moved by a forklift, take care to avoid scratching panels by using a pallet or protective support under the stack of panels.

Any local deformation due to inadvertent and excessive local pressure or to vandalism should be reversed as soon as possible to avoid eventual local stress crazing. To avoid panel deformation and risk of injury, under no circumstances should DynaGlas be walked on, whether on the ground or on the roof after installation.

DynaGlas panels will expand and contract during the life of the panel. To avoid excessive expansion and contraction of the panel and avoid warping or premature cracking at faster point, care should be taken to observe the following.

1. Install panels during temperatures of 50-77 degrees F (10-25 C)
2. Predrill panels at fastening points before screw installation.(Larger holes may be required for darker colored panels)
3. When the end of panels are inserted into a recessed channel, allow 1/8” - 1/4” space from the back of the channel for to allow expansion and contraction.
4. Apply the panels to properly spaced purlins. (See recommended load charts)
5. Don't apply more fasteners than recommended.
6. Avoid using excessively long panels. Click to download Benefits of Lapping Panels

Note: Darker colored panels may expand and contract more than lighter colored panels. Extra care should be taken when installing dark colored panels.

DynaGlas is sufficiently flexible to allow vertically positioned panels to conform to arched construction. It is recommended that panels be affixed to curved surfaces where the curve radius is greater than 16 feet. At a minimum, the radius of the curved surface must be greater than 13 feet. Affixing the panel to tighter radii surfaces may result in local stress crazing and deterioration over time. To determine the radius of an arch roof, apply the formula in the section below.

Obtain the measurements of “h” (height of arch) and “w” (width of arch) as indicated in the illustration at left. Using these measurments, determine the value of “r” (radius of arch) using the following equation:

For maximum economy, installation ease, and pest control, DynaGlas panels can simply be extended approximately 6" below ground level.

DynaGlas panels have a UV-protected exterior surface and a condensate-controlling interior surface. Panels are to be installed with the labeled side out (exposed to the weather) as indicated by the sticker affixed to the UV-protected side of the panel. If the label has been removed, install panels with the edges pointing down, not up.

To ensure a full 4' or 6'net coverage, panels should be stretched slightly across the width during installation.

It is best if panels are installed when the temperature is about average for the region. This helps to ensure that the panels won't be installed when they are fully expanded or contracted due to warm or cold temperatures, respectively.

Panels overlap vertically by one corrugation and should be overlapped away from prevailing winds. Vertical laps are fastened together by means of Self-Grip Lap Fasteners (click here for more detailed information about Self-Grp lap Fasteners).

For horizontal overlaps, the upper panel should overlap the lower panel by 3" to 4". Horizontal overlaps should be centered over purlins or girts. Sealants are not required between overlapping panels. The use of sealants or caulking will only result in unsightly dirt streaks within a short period of time.

DynaGlas Plus has extremely effective built-in condensate control properties on the interior surface of the panel. To ensure proper condensation flow after installation, a minimum roof slope of 15% (approximately 2” per foot) must be maintained.* (Note: DynaGlas “SE” is intended for use on side, end, and partition walls.)

DynaGlas can be cut several panels at a time with a power circular saw equipped with a standard woodworking blade (fine-tooth, hollow ground, 10 to 12 teeth per inch). It is also advisable to install the blade backward. This will help minimize chipping and ensure a staight cut.

Single panels can be cut with standard shears or snips. A saber saw equipped with a fine-tooth blade can also be used, but proper support of the panel is recommended.
