DANA Ultra Panel is a fiberglass reinforced translucent panel manufactured from a specially formulated U V stabilized polyester resin system reinforced with high quality glass fiber to ensure UV and weather stability .The weather surface incorporated retains its smooth finish to a greater period of time providing self cleaning benefits.
– DANA Ultra is manufactured from a new generation composite resin system, which is then mixed with quality glass roving materials.
– The extra heavy duty non-porous weather surface prevents water absorption, osmosis and gives sound protection against sand abrasion.
– Reduce fibre show in comparison to the standard commercial grade translucent roofing products.
– UV-stabilized non-delaminating weather surface technology
DANA Ultra panel is suitable for use on food manufacturing buildings, shopping centers, supermarkets and any commercial or industrial projects where long term high quality light is required.

DANA Ultra sheets are normally manufactured in any lengths up to 6.3 meters, but longer sheets are also possible, subject to our confirmation. Cover width shall depend on the type of profile .for profiled sheets and for flat sheets the width can be up to 1.2 meters.

Assembly of the skylight
To allow the natural linear thermal expansion of the sheet, the drilled hole should be at least 1.5 times the diameter of the mounting screw & a rubber washer should be utilized in between.
- The sheets should be screwed to purlins with fasteners not exceeding 200mm centers.
- Vinyl Lap seal or mastic must be used between when fastening to steel.
Roof light Load Span
Load / Span calculation is varied according to the required profile details of the customers. The deflection limitation used for calculation is as follow:
- Downward pressure loading deflection should not exceed 1/30 + h of the span and should not be more than 50mm.
- Suction uplift loading deflection should not exceed 1/15th of the span and should not be more than 100mm.
Roofs are dangerous places to work and it is recommended that the following information be included in the “Health & Safety File”.
No person should have access to a roof unless under the direct supervision of an experienced roofer who should be sufficiently competent to assess any risks and take the necessary action to reduce such risks.
Do not walk on rooflights at any time, ALWAYS use crawling boards.
Transportation, Handling and Storage
Sheets are generally supplied loose. Store sheets on flat, clean, level battens located not exceeding 500mm centers. They should neatly stacked to ensure even weight distribution
.Secure against theft and from being blown away.
Continuously protect sheets stored in open with waterproof Opaque covers, otherwise even on relatively dull days sheets stacks will act as a solar battery boiling any entrapped moisture and discolouring the sheets. Inspect regularly to ensure that moisture has not penetrated the stack.
When carrying the product, care must be taken not to twist them. They must be carried by at least two people or more it depends of the length of the panel.
Sheets should be regularly cleaned with warm water and detergents to maintain light transmissions.
