Triangle Windows for domes

Our custom geodesic triangle skylight windows are designed to enhance incredible views. Enjoy wide and tall panoramic views whether sitting or standing from inside your dome. Relax in sunshine with an open glass wall that surrounds you on all sides. Bask in bright blue skies overhead or watch storms pass by.

4D Skylights™ feature a powder coated welded aluminum frame, integrated rubber compression gaskets, and Dome Inc. exclusive drip cap. The 4D triangle skylight window delivers exceptional durability, extended lifespan, and a 10 year sealed glass no leak warranty. Our modern design adds a clean, sophisticated touch to any geodesic dome home. Maintenance-free aluminum skylight windows will not rot, do not require caulking, no painting or screws to retighten.

Window Manufacturing

Respected window manufacturing giants Anderson Windows and Marvin Windows stopped offering skylights 30 years ago due to persistent water infiltration issues and low demand. Currently, Velux is the premier operable square skylight manufacturer. Dome Inc. adopted a solid curb frame design. Our sixth-generation custom skylights feature exclusive design considerations for ice, snow, and rain that affect dome skylight windows.

The 4D aluminum skylight

The 4D aluminum skylight frame sits on a 4" curb. The roof is shingled, step-flashed up to the top of the curb, then the aluminum-framed glass unit is set on the curb, overlapping the flashing. Our windows are fixed closed. All windows are custom-made to fit a specific location on your dome.

The welded frame weep system removes moisture if condensation forms inside the window. A water gutter collects condensation from the interior glass surface and drains it outside onto the shingled roof. Dome Inc.'s 4D Skylights™ use all stainless-steel fasteners and have a continuous thermal break.

Overhead skylights meet Building Code requirements with a laminated inner safety pane. The standard skylight unit is double pane with Low-E Energy Coating inside the Argon gas-filled airspace. Exterior frame colors include Arctic White or Mocha Brown. Upgrade options include Triple Pane Glass, tint, Solar Cool Mirror tint, more frame colors, and clear impact-proof polycarbonate glass.
