The Northlander™ Skyview Low Profile Polycarbonate Roof

An aluminum coupler system for translucent sheets that installs on customer provided framework.

Description

Polycarbonate Roof on Customer Provided Framework

Often we have found that customers come to us with glazing requirements, but they have an existing framework that doesn’t require the strength of our big Skyview structural beams. That’s why we offer Skyview Low Profile.

  • Works with 16mm sheets.
  • Very flexible, easy to install.
  • Mounts on existing aluminum, steel, or wood frame work.

Aluminum Couplers for Polycarbonate
With the Skyview Low Profile system, it doesn’t matter if your rafters are 16” or 24” apart. And it doesn’t matter if there are slight inconsistencies in rafter spacing, all you need to do is trim the sheets to suit your openings. Alternatively, you can run horizontal strapping (purlins) and space the Skyview Low Profile glazing bars equally.

Our extruded aluminum base and pressure cap with gaskets are your best choice for a long lasting, water proof roof system. Much more durable and leak proof than systems that use polycarbonate joiners.

Thinking About a Glass Roof?

Our polycarbonate sheets are light weight, provide good insulation values and are so much easier to install than glass. Solarium glass is very heavy, and if you are using laminated glass it can be prone to cracking during installation or from subtle shifting of the foundation. Polycarbonate sheets are many times stronger than glass, acrylic or even modified acrylic.

Need To Repair a Glass Roof?

Don’t forget how hot it was with that glass roof! And maybe it was leaking at the purlins (the joints between the glass units). Re-glaze with polycarbonate, it’s cooler, and the sheets run the full length of the roof, without the leaky purlins of glass systems.

Solar heat gain coefficient (SHGC) is the ratio showing the amount of the sun’s heat that can pass through the glazing. The lower the number, the less heat build up you will have in your sunroom.

U-Factor (or U-Value) is the rate of heat transfer from warm to cold areas in watts per square metre Kelvin (W/m2K). Lower numbers mean better insulation. Typical values:

  • single glazed glass, 5.91
  • double glazed with 13mm air space, 2.73
  • double glazed with 13mm air space & low e, 1.70
  • double glazed with 13mm air space, low e & argon, 1.36
