DIRECTIONS FOR MECHANICAL INSTALLATION
-
Determine the location of the Polar Blox™ per Manufacturer’s recommendation (see above).
-
Clean the roof surface where the Blox will be placed with xylene or isopropyl alcohol. Allow to dry completely.
-
Apply an even coating of transparent silicone sealant to the Blox base. We recommend SB-190 as it is a sealant and adhesive. (Use a non-acetic acid silicone on Galvalume® or galvanized roofs.)
-
Each Polar Blox™ should be positioned with the holes against the roof and the face of the Blox toward the roof ridge.
-
Use #12 or #14 Self-Tapping screws with neoprene washers under the heads. Screw through the Polar Blox™ and roofing material, into the purlin or structural support.
-
Tighten the screws to ensure an adequate squeeze-out of silicon sealant around the entire edge of the Blox. Do not over-tighten. Run a bead of silicone along any voids along the perimeter.
-
To ensure a weather-tight seal, use a gloved finger to smooth the sealant along the edge of the Blox.

DIRECTIONS FOR ADHESIVE MOUNTING
- Determine the location of the Polar Blox per Manufacturer’s recommendation (see above).
- Clean the roof surface where the Blox will be placed with xylene or isopropyl alcohol. Allow to dry completely.
- Generously apply an even coating of adhesive to the Blox base, covering the entire area to be mounted. We recommend SB-190 as it is an adhesive and sealant.
- Each Polar Blox™ should be positioned with the holes against the roof and the face of the Blox toward the roof ridge.
- Press each Polar Blox™ firmly against the roof surface. Make sure there is no air trapped under the Blox and that there is an adequate squeeze-out of silicon adhesive along the entire perimeter.
- To ensure a weather-tight seal, use a gloved finger to smooth the adhesive along the edge of the Blox.
