30" x 36" Fixed Flat Roof Deck-Mount Skylight

30" x 36" BA-DXF Fixed Flat Roof Deck-Mount Skylight

Dark, artificially lit interiors shouldn't be the price of energy efficiency. Yet many property owners with flat roofs face exactly this problem: traditional skylights let in light but also let out heat. This drives up energy bills and makes it nearly impossible to achieve passive house certification. Buildings end up feeling dim and uninviting, or they fail to meet modern energy standards.

The 30" x 36" BA-DXF Fixed Flat Roof Deck-Mount Skylight addresses these concerns head-on. With an impressive U-value of 0.22 BTU/h ft² °F (R-value 8.1), this non-opening skylight provides superior insulation while flooding your space with natural light.

Designed specifically for flat and low-slope roofs, it combines triple-pane passive glazing technology with multi-chamber PVC construction to deliver energy efficiency that meets passive house requirements.

Why Should You Use the 30" x 36" BA-DXF?

• Exceptional Energy Efficiency: Boasting a U-value of 0.22 BTU/h ft² °F (equivalent R-value 8.1), this skylight minimizes heat loss and keeps your building comfortable year-round. It's ideal for passive houses and energy-conscious projects where every BTU counts.
• Triple-Pane Passive Glazing: The DU6 glazing unit features three panes with warm spacers, argon gas fill, and two low-E coatings that work together to block heat transfer. The exterior glass is tempered for durability, while the interior glass is laminated for added safety—protecting the building and its occupants. With a sound reduction index of Rw 34 dB, it also minimizes exterior noise for a quieter interior.
• Superior Thermal Frame Design: The multi-chamber PVC frame is insulated with polystyrene, eliminating thermal bridges that plague traditional skylights. This means consistent indoor temperatures and lower heating and cooling bills.
• Versatile Roof Compatibility: Whether you're working with TPO, PVC, EPDM, or torched-down membranes, this skylight integrates seamlessly. This model also has an aluminum termination bar that securely fastens the roofing membrane directly into the frame, ensuring a watertight seal.
• Impact-Resistant Construction: Rated Class 5 for impact resistance (EN 14351-1), this skylight withstands harsh weather conditions like hail and debris, providing long-lasting performance in any climate.
