Transparent sheets, daylighting roofing with polycarbonate material
ONDUCLAIR offers excellent light transmission while protecting against UV. ONDUCLAIR is a solution that is both attractive and durable.
Transparent polycarbonate sheets have 90% of light transparency. Even after 10 years of age the transparency of the polycarbonate is of 80%
High impact resistance, no damage under hail up to 135 s/m
Suitable for all climate: can be used between -30 C / +130 C.
Polycarbonate is UV resistance!
50 years of daylighting roofing experience
The polycarbonate sheets should be stored on pallets in a covered and ventilated place.
Installation and Security
During installation do not step on the sheets, the breakable sheets security instructions should be applied.
Resistance to Impact From Inside
Polycarbonate sheets are impact resistant. Howeever when used in buildings like sport halls, an extra surface protection is required.
Installation on the Roof
General Guidelines for Battens:
Steel box profiles
Maximum width: 40 mm
Maximum thickness: 1,5 mm
Maximum width: 60 mm
Maximum height: 80 mm
The span between battens should be choosen in the following table. These valors are calculated in order to give three times security to the breakability and for a sheet displacement lesser then 1/100 of the span
During the installation the corrugations must be layed parallel to the pitch and the sheets should be installed in a direction opposite to the prevailing wind.
The sheets can be cut with a thin teeth (5 teeth/cm) hand saw or spiral power saw.
The corrugations must be layed parallel to the pitch.
The sheets should be installed in a direction opposite to the prevailing wind and the overlaps should be protected against the wind.
The laying must always start from the eaves. The overlap of each consecutive raw should cover the preceeding sheet.
The overlapping must be done on top of the batten and the overlapping lenght should be at least of 150 mm for all type of profiles.
The overlapping should be done in a direction opposite to the prevailing wind.
-Protected or normal area; half corrugation
-Windy area: 1.5 corrugation
PC.: Follow the application instructions for ONDULINE HR sheets.
P.O.: 1,5 corrugations
S.P.: 2 corrugations
H3.: 1 corrugation
The sheets are fixed on top of the corrugations on the roofs and inside of the corrugations for wall cladding with screws or tirephons.
The holes should never be opened on a distance less then 50 mm from the edge of the sheets. The holes are opened with a power driller and the hole diameter should always be 4 mm larger then the fixing device diameter. The surrounding of the hole should be cleaned from all dirts such as dust, drilling residues, etc. for proper application of the washer and gaskets.
While use with fibre-cement sheets take all precautions to prevent the chemical diffusion of alkaline which may cause cracks and mechanical deformation on the sheets. The screws should be fixed in order to prevent all leakages but also to let the sheets dilate. The sheets must never be nailed. The use of rivet and nailing is prohibed (1).
(1) Except for the HR profile used together with ONDULINE HR sheets as skylighting purposes
Special Fixing Parts
Precaution should be taken against wind at faces (like gable wall end) by using L profiles.
Fixing devices and accessories should be choosen from products made within the international quality standarts in order to give the minimum mechanical strenght, leakage resistance and durability. The staggered sheets should be fixed on each batten on top of the corrugations. In addition the sheets should be screwed in the middle of the batten
on widthwise overlapping. The use of tapping screws. is recommended. The screws should be fixed together with the gasket and the space under the corrugation should be filled to prevent any damage to the corrugation.
Anti - Leakage
If the slope is 25 % or less slicone mastic or double sided self sticking butyl stripe should be used between overlappings on both sides to prevent any leakages.
On lenghtwise overlaps zig zag installation is recommended for the drainage of the humidty drops which may be caused by condensation.
The general guidelines for ventilation is the same as the actual standart regulations. The use of polycarbonate sheets may cause temperory condensation regarding the climate and humidity conditions. Direct ventilation arrangements is mandatory on roofs and eaves or on top or bottom of the wall claddings. The ribs of the sheets should never be closed for proper ventilation.
The under-side of the sheets used for skylight purposes should be ventilated in order to not exceed 130C. The ventilation surface (air entry and exhaust) should be equal or more then 1/500 of the roof surface. (At least 380 cm2/ml)
Polycarbonate sheets can be used also on curved surfaces. The minimum radius: h X 200. On installation the direction of the corrugation should be parallel to the curved surface. In order to align perfectly the sheets the installation of the battens should be linear to the curve
For vault roofs:
ONDUCLAIR polycarbonate sheets can be used both for vertical or horizontal wall cladding. The maximum accepted vertical deviation angle is 15 in siding surfaces. The corrugations should be installed parallel to the slope or vertical to the side. The sheets should be protected from the external effects or against collision by starting the cladding 1.50 m higher then the ground.
Lenghtwise Overlapping lenght should be at least of 100 mm for all type of profiles. For Widthwise Overlapping keep the same installation rules of roofing.
While fixing top or bottom sides never use flange on facade of the sheet, leave 10 mm of space with water leakage and ventilation precaution.
The overlapping must be done on top of the batten and the overlapping lenght should be at least of 300 mm for all type of profiles. Avoid lenghtwise overlap on the ridge to prevent any water leakage.
Double Layer Installation
The ONDUCLAIR polycarbonate sheets can be installed in double layer with a minimum space of 60 mm between the sheets for proper ventilation.
Finally the reaction of the Polycarbonate sheets against acids and bases is satisfactory. In addition it is resistant to gypsum and cement elements used in the buildings and to mineralized air. The mould, moss, micro-organisms and the rodents have no effects on the quality of the sheets. However it is better to avoid the contact with the solvents.
High-level, sustainable natural day light for the buildings
ONDUCLAIR provides long term sustainable optical performans through the UV protection layer.
Resistance to extreme air temperatures
ONDUCLAIR can resist extreme temperatures changing between +130° and -30°C. That’s how it can be applied to many geographical areas around the world.
Resistance to impact and hail
ONDUCLAIR doesn’t get broken under ordinary usage conditions. It can be applied very practically, so it is suggested for sports facilities and areas which are affected by hail regularly (Please see Application Guidlines).
First class fire evaluation
ONDUCLAIR’s applicability on different types of roofs and fire resistance is approved by Euroclass B-s1, d0.
Physical and Chemical Features
Polycarbonate sheets act conventiently to acids and alkalines. They are also durable to plaster and cement used in the buildings. They show resistance to salty air. Algea, mold, microorganisms and rodents don’t have effect on the qualities of the sheets. However, polycarbonate shouldn’t be contacted with resolvent materials.
