Redwave polycarbonate hollow sheet is made from virgin polycarbonate material and the high concentration UV coextrusion. The sheet possesses the features of light in weight, pervious to light, impact resistance, heat isolation, flame retardant, endurance, etc.
In addition to the above features, Crystal PC hollow sheet is with the effect of “glittering and translucent” making the light penetration downier with better aesthetic visual effect.
Best feature of the product：UV co-extrusion process for resistance of yellowing, sound insulation, heat preservation, safe and transparent.

1.1 Installation by inserting
A.Because the protective film inserted in supporting frame has a bad affect on adhesion between crack filler and PC panels, protective film 5-10mm wide inserted should be cut off before PC products are inserted.
B.Because the PC panels don't change in the same range when expand with heat and shrink with cold as metal frame, and they can be bent to some extent and resit air pressure, You must take the following factors into consideration: suitable quantity inserted, the space allowing their expanding or shrinking with the change of temperature and right thickness of PC panels.
1.2Installation by screws:
A.For any outdoor installation or installation in environment with temperature difference of 8℃,enlarge the aperture of any bolt or rivet much be enlarged to allow PC panels expanding or shrinking with change of temperature. Generally, the aperture shall be 50% bigger than the diameter of bolt. Use aluminum rivet. Self-drilling screw must be abandoned.
B.Use silica gel to fill all apertures and cover their exposing parts to prevent PC panels from map cracking by cleanser which may inserted in apertures.
C.The head of rivet should be 1.5-2.0 times bigger that the stem. Use gasket to fill between PC panels and rivet head to prevent PC panels getting directs pressure from rivet head, then lessen their pressure in this way.
D.Don't tighten screw too much in case stress may cause thereof.
E.Don't use PVC gasket and water-proof adhesive tape with asphalt content .
F.Fix the metal pressing strip on long and short edges of PC panels. Remain a space for their expanding. Strengthen installation stability
Limitation to know :
Keep PC panels away from wet cement surface or any acid or base materials.
Keep PC panels away from any organic solvent or any glue or paint composing of organic solvent.
Keep frame clean and jointing groove flat and smooth .
Choose right thickness of PC panels,allow flexure radius .
Remain space for expanding , pay attention to inserting depth. Don’t know drill any hole in curved part of sheet.
Use only neutral silica gel and use only EPDM rubber strip or washer as sealant.
Use electrical tools (tungsten carbide saw )to cut; During cutting, stabilize
PC panels to prevent their vibration and never pill off protective film .
In case that marks have to be made before cutting,try to mark on protective
film;If the marks must be made directly on PC panels,use wax crayon instead
of any sharp tool to mark .
Never pill off protective films until installation is completed .
ALUMINUM FOIL TAPE,FLASHING TAPE, PEEL/STICK ROOF TAPE, has a heavy aluminum facing together with an extra thick rubberized asphalt based adhesive system. The aluminum facing is embossed to provide flexibilty for wrapping irregular shapes and surfaces.
The Xunda-T 700 series self adhesive bituminous aluminium foil tape is recommended for most types of roofs, windows and flashing problems including:
The specification of the tape consists of three layers,
Adhesive: Fexible modified bitumen adhesive compound.
Film backing: Aluminium foil
Interleaf: Antiadhesive Film Treated with Silicone
self adhesive bituminous aluminium foil tape Features:
APPLICATION: The surfaces to be sealed must be clean, dry and free of loose rust, scale, dust, talc and dirt. All oil, grease, silicone or other contaminates should be first removed with a suitable solvent/cleaner.
For older roofs use a stiff brush to remove all loose granules and surface elements.
Porous surfaces should be primed with a common asphalt based primer and allowed to dry before Xunda-T 700 is applied.
Install Xunda-T 700 by gradually peeling away the plastic release liner while rubbing the Xunda-T 700 to the surface.
Hint: prevent bubbles under the product by using your hand to squeegee out air by wiping your hand towards the roll as you set the tape to the surface.
Overlap seams or sealing are of application by 3 inches.
