Marlin System 50 slope glazing is a custom fabricated system for overhead glazing applications. Internal condensation gutters allow moisture to be drained to a continuous transition gutter. It features a rigid polyurethane "thermal barrier" as an integral part of the framing members to ensure outstanding thermal performance.

System 50 has a 2" x 5" rafter designed to accept a steel insert for longer spans. The system is assembled with screw race construction or shear block method. Snap in fillers conceal bolt connections at head and transition to provide a clean attractive appearance.

The system accepts 1/4" to 1" glazing options. Glazing is accomplished from the exterior with screw applied pressure plates and wet seal. Snap on cover caps provide a clean, flush grid appearance

Marlin Sunrooms Quality Features

Thermally Broken Framing - Isolates the exterior metal from the interior to reduce heat loss and condensation.

Variable Roof Pitch - Custom designed and built to meet your exact needs

Internal Gutter System - Provides drainage for any condensation that may appear (a must for enclosing a hot tub).

Screw Race Construction - Allows for faster and stronger fabrication and installation which will save you money.


Results of performance test include:

-Air infiltration per ASTM E283: 0.05 cfm @6.24 psf.

-No water penetration per ASTM E331: up to 15 psf.

-Structural Loads per ASTM E330: +80 psf.

-CRF rating per AAMA 1502.7: 74
