Description

Technical Data

Special Layers

Profiles

Polycarbonate Multiwall is a high performance roofing sheet which has been designed for industrial, commercial, architectural and domestic applications where insulating glazing is required.

It offers a 10 year non-prorated warranty against loss of light transmission and yellowing in accordance to ASTM 0-1003, thanks to the co-extruded UV protected PC layer fused to the PC substrate of the sheet.

STRUCTURAL CONSIDERATIONS

Load Deflection

When Polycarbonate twin wall sheet is used as a structural element in roofs and walls, the forces applied by wind and snow loads must be absorbed by a suitable structure. Also, adequate locking devices must be used to protect the whole structure (PC sheet and metal or wood structure) against wind suction.

The anticipated structural load values are specified in local building regulations. The total applicable load deflects the sheet. For safety and aesthetic reasons, the maximum bend should be limited to 5% of the dimensions of the shorter side of the sheet.

	For a 4′ wide sheet
Maximum Purlin Spacing (inches) sheet deflection -1″
Load (lb-f/ft2)	15	30	45	60
6mm	31″	24″	12″	–
8mm	38″	28″	18″	10″
10mm	45″	34″	28″	24″
16mm	75″	43″	36″	30″

	For a 6′ wide sheet
Maximum Purlin Spacing (inches) Sheet Deflection -1″
Load (lb-f/ft2)	15	30	45	60
6mm	25″	9″	–	–
8mm	36″	26″	12″	–
10mm	44″	33″	27″	20″
16mm	60″	40″	36″	30″

Heat Expansion

Glasteel’s PC sheet has a higher heat expansion coefficient than standard construction materials such as glass, steel and aluminum. Specific clearance between the sheet and the structural frame has to be calculated in order to ensure proper installation.

Material	Heat Expansion Coefficient (inch/ftºF)
Makrolon®	4 x 10-4
Glass	5 x 10-5
Steel	8 x 10-5
Aluminum	1.6 x 10-4

Fire Behavior

Glasteel’s Macrolux Multiwall sheet is produced using high-quality polycarbonate resin made by Bayer. It does not burn easily and has been defined as a self-extinguishable material by international standards in different countries.

ASTM E84-01	ClassA (NFPA); Class (UBC)
ASTM D635-74	Class CC1
ASTM D2843-93	Low Smoke Density (UBC standard No. 26-5)

HANDLING

In order to avoid condensation in the sheet cells and sheet deterioration, always place the sheet with the cells in the vertical direction.
Always store the sheets in horizontal position, never against the floor. Apply aluminum tape to seal the cells after cutting the sheet.
Do not walk over the sheets.
Do not apply direct load on the sheet with foot or knee. Use wood platforms or supports to spread out the pressure during installation.
Remove IIV protecting masking only and right after installation; never before and never after hours of being installed.
Glasteel’s PC Sheet can be cut to size using tools for standard materials such as cutters and saws. However, it is recommended the use of a table with fixed knives for a cleaner cut.
It is not recommended to drill holes in the sheet. Rather the use of aluminum or Polycarbonate profiles to fix the sheets to the structure is recommended.
Never use PVC profiles when installing Macrolux Multiwall sheets.

Cleaning and Maintenance

For general cleaning it is recommended to use a non-abrasive, solvent free neutral soap with water.
Rinse with high-pressure washer and use a soft cloth or sponge to loosen any remaining of dirt and grime. Never use abrasive cleaners or brushes. Do not scrub the sheet surface.
Never clean with gasoline, benzene or acetone.
