Colour Lok

Colour LOK is a high rib roof with 2 pan using clip-on system profile. This profile is specifically ideal for low pitch roofs with strong wind and heavy rainfall terrain. The anti-leak capillary design and conceal clips on this profile can accept roof pitch to as low as 2 degrees.

Features

  • Most widely used metal roofing profile for commercial projects
     
  • High Rib anti-leak capillary design and conceal clip provides exceptional water proofing characteristics.
     
  •  No exposed screws/fasteners hence avoiding leakage problems caused by improper installation
     
Thickness Available:
  • 0.48 mm
  • 0.54 mm
  • 0.60 mm

Clips & Accessories

  • The Colour LOK clips are specially designed to achieve great interlocking application.
     
  • Use Water Head M5 x 30 Self Drilling Screws for fastening of clips to purlins.
     
  • Use Hex Head M5 x 20 Self Drilling Screws with Neoprene Washer for stitching of flashing or capping onto roof shet.
     
  • Use Hex Head M5 x 65 Sekf Drilling Screws with Neoprene Washer for fastening of edge of roof sheets to Purlins.

Coating Specifications

Coating Specifications
Solar Reflectivity (SR)

Solar reflectivity or reflectance is the ability of a material to reflect solar energy from its surface back into the atmosphere. The SR is value is a number from 0 to 1.0 A Value of 0 indicates that the materials absorbs al solar energy and a value of 1.0 indicates total reflectance. Energy Star requires and initial SR value of 0.25 or higher for steep slope (>2:12) roofs and 0.15 or greater after three years. Low slope roofs require an initial SR value of 0.65 or higher and 0.50 or greater after three year.
 

Solar Reflectance Index (SRI)

The Solar Reflectance Index is used for compliance with LEED requirements and is calculated according to ASTM E 1980 using values for reflectance and emissivity. Emissivity is a material’s ability to release absorbed energy. To meet LEED requirements a roofing material must have a SRI of 29 or higher for steep slope (>2:12) roofing and a SRI value of 78 or higher for low slope roofing.
