ADVANTAGES OF MULTIWALL

Tuflite Multiwall Polycarbonate sheets are the most versatile

polycarbonate sheets in the market. The hollow and multi

cellular structure provides the flexibility while maintaining the

strength of the sheet.

They are manufactured from UV stabilised resin that ensures

the product meets the highest quality standards. Due to its

unique structure and design, hollow & cellular sheets can

be very light and can go from twin wall to triple walled

structures ensuring its lightness and improving its thermal

insulation depending upon the applications. With a wide range

of options in terms of clear as well as diffused light, Tuflite

Hollow & Cellular sheets can provide a maximum of 80 % and

minimum of 25% light transmission. They allow light to enter,

at a significantly lower heat transmission level, to ensure

optimum illumination with maximum comfort.PRODUCT RANGE

INSTALLATION

Tuflite multiwall versatile polycarbonate glazing system is advanced in design yet simple to install. The sheets simply slot into a h- bar ready for fixing to the structure. A two piece h- bar is also available for increased flexibility. The glazing bar system allows for thermal expansion through the sheet, hence

the structure is 100% water tight.

INSTALLATION INFORMATION

1. Always install Tuflite Multiwall with vertical ribs in glazing & cladding applications and in the direction of the slope for roofing applications. This will ensure easy drainage of moisture in case of condensation. Improper installation can lead to accumulation of moisture within the flutes & promote the growth of fungus and moss, especially in tropical regions.

8. One Piece H Bar SystemPlace the next bar on the other side and secure it to the support structure.

Two Piece H Bar SystemPlace the sheet between the two secured glazing bars. Position the first top glazing bar in line with the base. Secure the two bars using a rubber mullet. Once the next sheet is installed, the second and subsequent top glazing bars can be fitted.

9. Repeat steps 6-8 until sheets are in position.

10. When using Aluminum End caps, place the gasket along the end of the Multiwall sheet only, stopping the H Bar.

11. Fasten the Aluminum End Caps with a screw to the H Bar. On the underneath of the Aluminum End Cap drill a small weep hole where it meets the H Bar.

12. Use Aluminum/ Polycarbonate End Cap to close off the open edge of the first and last glazing bars.

2. Follow recommendations for rafter and purlin spacing as specified for Tuflite Multiwall sheets.

3. Tuflite Multiwall sheets can be cut using a sharp blade, hand saw or a circular saw with a fine tooth blade suitable for plastics. Dust par-ticles (swarf) should be cleared from the flutes using compressed air (or sucked out with a vacuum cleaner.) All cut edges should be free of notches. In case of reducing the width of Tuflite Multiwall sheets, trimming should be done as close as possible to the previous rib so that the optimum support is achieved.

4. Remove masking partially, from the edges of the sheet and apply a breather tape to the top and foil tape to the bottom ends.

5. Two Piece H Bar SystemPlace the first and second measured and cut base glazing bars on the structure.

6. One Piece H Bar SystemSecure H Bar to the purlin or rafter with a screw (gauge not exceed-ing 12g) at no greater than 1200mm apart.

Two Piece H Bar SystemFasten the Base Glazing Bars to the rafter with self fastening screws (10 gauge - 16 tpi) at no greater than 500 mm apart by fixing through the center of the base glazing bar and securing it firmly onto the sup-porting structure. (Self fastening screws for wood are 30 mm long; self fastening screws for metal are 21 mm in length)

7. Pull the masking back on the sides of the sheet and placethe H Bar C gasket long the whole length of both sides of the sheet Place one side of the sheet into the H Bar.
