New From Major Industries: Clima-Tite™



Clima-Tite™ takes the unmatched dependability of our standard Guardian 275® aluminum-based translucent panel daylighting systems and transforms them to a new level of thermal performance and condensation resistance.

The key to the high performance of Clima-Tite™ is pultruded fiberglass. By replacing traditional aluminum support structures with fiberglass, we're able to offer a system that provides better U-factors, increased CRF values and a unique snap-to-lock installation feature that saves labor costs and eliminates the need for unsightly visible fasteners. Clima-Tite™ systems also provide built-in water management for long-term performance.

Like our Guardian 275® translucent panel systems, Clima-Tite™ features Major’s Ultimate Series™ FRP face sheet technology for unbeatable weathering performance and unmatched warranties. The Ultimate Series™ offers superior color retention, an erosion veil for extreme environments, and industry-long warranties.


In order to create the pultruded fiberglass members in a Clima-Tite™ system, continuous strands of glass are combined with resins and pulled through a heated die. Pultruded fiberglass has numerous advantages over aluminum, including dimensional stability and increased protection from temperature differences and condensation, which can enhance occupant comfort.

Other benefits of a Clima-Tite™ fiberglass system include:

  • No visible fasteners for a clean look
  • Corrosion resistant and durable - long-lasting performance
  • Low thermal conductivity - eliminates the need for thermal breaks and improves performance
  • Electrically non-conductive - unlike aluminum
  • UV resistant
  • Paintable just like standard aluminum framing
  • No special handling or transportation requirements
  • High impact resistance - reinforcing fibers distribute load


Clima-Tite™ Window-Wall systems allow you to provide light and ventilation control for building occupants plus superior thermal performance compared to traditional window or translucent wall systems.

By incorporating GThurm™ windows from Graham Architectural Products, which offer an advanced composite design plus stainless steel hinges and white bronze locking hardware for long-term performance, we can provide a system that's unmatched in the industry. Numerous glazing options are available, including single, double and triple-glazed glass, low-E coatings, as well as optional features like multi-point casement locks and integral mini-blinds.


Fiberglass is environmentally sound, as the manufacturing processes require less energy when compared to aluminum (about 80% less embodied energy). Also, the main ingredient in fiberglass is silica sand, an abundant natural material. Once properly converted, the inherent thermal properties of fiberglass allow for reduced HVAC loads, which can reduce greenhouse emissions.

The long lifespan and durability of pultruded fiberglass also delivers reduced costs over the lifetime of the system.
