Skylight FMB 22 1/2 x 22 1/2 Deck Mounted Bronze Glass by SIG

Description

Product Overview

The FMB 22 1/2 x 22 1/2 deck-mounted skylight from SIG Skylights is engineered to deliver exceptional performance in a compact, square format. Constructed with a heavy‑gauge aluminum frame that is powder‑coated in a rich bronze finish, the unit resists corrosion, UV fading, and the harsh elements commonly encountered on residential and commercial roofs. Inside the frame, a double‑pane tempered glass panel provides superior insulation, reducing heat loss in winter and limiting solar gain in summer, while maintaining crystal‑clear visibility for natural light.

Every component of this skylight is designed with precision. The glass is tempered and insulated, offering a high safety rating and long‑term durability that outlasts standard acrylic or plastic alternatives. The frame’s ribbed flange measures an extra‑wide 4 5/8 inches, creating a robust sealing surface that integrates seamlessly with the built‑in curb. This design eliminates the need for additional flashing materials, simplifying the installation process and reducing the risk of water intrusion.

Dimensions are carefully calibrated to fit a 22.5″ x 22.5″ finished opening, making the unit a perfect match for standard roof decks and pre‑cut openings. At 28 pounds, the skylight is lightweight enough for most roof structures yet sturdy enough to withstand wind uplift forces up to 90 mph, as verified by industry testing standards. The product is proudly manufactured in the United States, reflecting a commitment to quality control and domestic sourcing.

Beyond its functional attributes, the skylight’s aesthetic appeal adds value to any building project. The bronze finish complements a wide range of exterior color palettes, from traditional earth tones to modern metallic schemes. The clean, square silhouette provides a timeless look that enhances curb appeal while delivering the practical benefits of natural illumination and ventilation.

Usage

This skylight is ideal for a variety of applications, including residential homes, cabins, small commercial structures, and light‑industrial facilities. Homeowners seeking to brighten interior spaces such as kitchens, bathrooms, or loft areas will appreciate the abundant daylight that reduces reliance on artificial lighting. In commercial settings, the skylight can improve employee well‑being by providing a connection to the outdoors, which has been shown to boost productivity and morale.

Installation is straightforward for experienced contractors and DIY enthusiasts alike. The built‑in curb and extra‑wide flange allow the unit to be set directly onto a roof deck without the need for separate flashing components. This reduces labor time and material costs, making the skylight a cost‑effective solution for new construction or retrofit projects. The product’s robust construction also makes it suitable for harsh climates, including regions with heavy snowfall, high winds, or intense sun exposure.

FAQ

Can this skylight be installed on a sloped roof?

Yes, the FMB model is designed for both flat and low‑slope roofs. The built‑in curb creates a watertight seal, and the extra‑wide flange accommodates the slight angle of a sloped surface, ensuring proper drainage and preventing water infiltration.

What maintenance is required to keep the skylight performing well?

Maintenance is minimal. Periodic cleaning of the glass with a non‑abrasive cleaner will preserve clarity, and an annual visual inspection of the frame and sealant will help identify any wear early. The bronze coating is formulated to resist fading, so no repainting is necessary.

Is the skylight compatible with solar panels or other roof‑mounted equipment?

The skylight’s compact footprint and robust frame allow it to coexist with nearby solar panels or HVAC units, provided proper clearances are maintained. Installation guidelines recommend a minimum distance of 12 inches from any other roof‑mounted equipment to ensure adequate airflow and access for maintenance.

How does the insulated glass improve energy efficiency?

The double‑pane insulated glass contains a sealed air space that reduces thermal transfer, keeping indoor temperatures more stable. This reduces the load on heating and cooling systems, leading to lower energy bills and a smaller carbon footprint.

What is the warranty coverage for this skylight?

SIG Skylights offers a limited lifetime warranty that covers defects in materials and workmanship. The warranty does not cover damage caused by improper installation, accidental impact, or misuse. Detailed warranty terms are available on the SIG Skylights website.
