Deck Skylights

Deck Skylights

The basement entry to this Hoboken brownstone was gloomy, thanks to a small deck overhead. The plan was to introduce more light by adding a skylight to the deck above.

Deck Skylights

Structural glass-block skylights are heavy, so the author ordered two smaller units instead of one large one to make handling easier.

The deck framing is partially supported by a concrete-block separation wall. Doubled 2x6 joists used to frame the rough opening for the skylight were reinforced with 1/4-inch by 5-inch steel plates.

To support the skylight, workers glued, nailed, and bolted a 3-inch-wide ledge to the rough opening. Plywood was used as temporary decking during construction.

The skylight units were installed one at a time, with shims as necessary to level them and provide full bearing. Grey silicone sealant supplied by the manufacturer was used to fill the joint between the two units.

With the skylight secured to the framing, workers installed the TimberTech XLM decking, which was secured to the joists with hidden fasteners. The decking was laid out from the edge of the skylight rather than from one of the deck edges.

The skylight has a non-skid finish and is flush with the decking.

When the skylight is covered with snow, an LED rope light helps brighten the area under the deck. In warmer weather, the illuminated skylight adds a unique decorative accent to the deck.
