Fixed aluminium-framed skylights on the Made-in-China index were listed from US$90.00–US$98.00 per square metre at 5 m² MOQ up to US$135.00 per square metre at 1 m² MOQ on 2025-08-27, with tempered-laminated glass and electric-opening roof units quoted as separate SKUs [S1]. In the North American residential market, replacement-windows pricing data published 2026-05-06 puts installed skylight-adjacent openings at US$450–US$2,800 each, with whole-project budgets of US$7,000–US$27,000 [S3].
The three cost layers that actually move a 2026 budget are: the glazing-and-frame unit itself (FOB factory cost), the flashing/curb install labour, and the long-tail shade or solar-screen accessory. Fisher Products' HeatBlocker exterior skylight shades are quoted per square foot for both standard and custom sizes — a line item that routinely adds 10–25% to a daylighting budget once heat-load and UV control are specified [S2]. For envelope specifiers cross-checking daylighting against the rest of the building skin, the system window & door comparison lays out how a skylight opening differs from a curtain-wall module in air- and water-leak testing.
FOB price bands: what US$90, US$98 and US$135 per m² actually buy
The Made-in-China index snapshot is the cleanest public reference for aluminium-frame fixed skylights: two OEM/ODM SKUs cluster at US$90.00–US$98.00 per square metre with a 5 m² MOQ, "more than 5 years" warranty and online technical guidance, while a single-piece 1 m² MOQ SKU is listed at US$135.00 per square metre with the same warranty posture [S1].
What is NOT in that band: electric-actuated opening mechanisms, Australian-spec aluminium roof systems, and tempered-laminated glass with high Solar Heat Gain Coefficient (SHGC) tuning are all listed as separate Quick-View SKUs on the same index, which means the headline US$90–US$135 figure should be read as a fixed-glazed baseline, not a turnkey operable unit [S1]. For project buyers, the safe move is to ask the OEM to itemise four line items — frame extrusion, glazing build-up, hardware, and flashing kit — so the SHGC, U-value and impact-class choices are not buried inside one square-metre price.
Installed cost envelope: turning factory price into a project line
For North American residential work, the 2026 cost guide for replacement windows treats a skylight as one window opening in the same installed-cost framework: US$450–US$2,800 per opening installed, with whole-house projects landing between US$7,000 and US$27,000 depending on material, window type, project size and brand tier [S3]. The wide per-unit spread is structural — a fixed deck-mounted Velux-style unit on a curb installed from inside the attic sits at the low end; a large custom curb-laid electrically vented unit with new framing, drywall return and interior finish sits at the high end.
For a specifier, the lever that moves that range more than any other is roof access. A unit that can be cut in and flashed from inside an attic on a standard asphalt-shingle roof is a one-day install with one carpenter plus one roofer; the same unit on a tile, slate or standing-seam metal roof requires outside scaffolding, tile cutting and a roofer-carpenter-electrician trio. That labour delta — typically a full day and a second trade — is the single largest non-glass line item separating the US$450 and US$2,800 ends of the range [S3].
Accessory cost: shades, screens and the 10–25% adder
Heat-load control is a separate budget line that building-envelope buyers regularly underestimate. Fisher Products' HeatBlocker exterior skylight shades are priced per square foot for both standard and custom sizes, with the custom SKU carrying the higher per-foot rate and the standard sizes acting as a price floor [S2]. Fisher markets the line on heat, UV and glare blocking for both home and workplace, with US manufacturing and an easy-install framing system that mounts to the exterior of the curb.
The way to size the line item is roof orientation and glazing SHGC. A south- or west-facing skylight with a high-SHGC double-glazed unit in a cooling-dominated climate typically justifies an exterior shade; the same opening in a heating-dominated climate with a low-SHGC triple-glazed unit rarely does. Across a daylighting package of 5–10 openings, planning 10–25% of the glazing subtotal for exterior shading is a defensible budget placeholder, with the exact figure set by orientation mix and HVAC balance rather than by a flat rule of thumb [S2].
Spec levers that move the price: glass build-up, frame, opening mechanism
1. Glazing build-up. Double-glazed tempered vs triple-glazed low-E vs tempered-laminated acoustic laminate is the single biggest cost driver on the same frame. The Made-in-China index lists tempered-laminated glass as a distinct, higher-tier SKU family rather than as the default, which is the clearest signal that laminated glass carries a premium over monolithic tempered [S1]. 2. Frame material. Aluminium alloy is the FOB-China baseline at US$90–US$135 per m²; thermally broken aluminium, PVC, and timber/aluminium composites all sit above that floor, and the installed cost guide's "average window costs by material" axis is where the brand tier is added on top [S3]. 3. Opening mechanism. Fixed vs manual centre-pivot vs electric-actuated (Australian-spec electric aluminium roof units are quoted as a separate SKU on the China index) is a step-change in price because of the actuator, rain sensor and control wiring [S1]. 4. Flashing kit. Standard curb flashing for shingle roofs is a stock item; tile, slate and metal-roof flashing kits are purpose-built and routinely 2–4× the stock-kit price.
Selection criteria: who a skylight is for, and where it fails
A skylight is the right daylighting move where the floor plan has a deep interior zone more than 5 m from any vertical window, where the roof structure can carry a curb without structural rework, and where the HVAC system can absorb the additional solar gain in cooling season or the additional heat loss in heating season. It is the wrong move on west-facing slopes in cooling-dominated climates without an exterior shade budget, on low-slope roofs where ponding and leak risk dominate, and on roofs with multiple penetrations already (HVAC, plumbing vent, solar conduit) where each additional opening compounds flashing risk. [S2]
For envelope buyers, the skylight vs system window & door cut frames the air- and water-leak testing delta: a unitised curtain-wall module is factory-tested as an assembly, while a field-built skylight curb relies on the roofer's sequencing. That sequencing is the failure mode behind the majority of skylight warranty calls and is the reason a reputable OEM's online technical guidance and multi-year warranty are not a marketing extra but a risk-transfer item [S1].
Standards and sourcing signals to track on a 2026 buy
Three documentation lines should be on every 2026 skylight PO. First, ask for the tested U-value, SHGC and Visible Transmittance (VT) on the exact glass build-up being quoted — not a generic brochure figure — and confirm the NFRC rating label where North American code requires it. Second, ask for the flashing kit part number matched to the actual roof covering (shingle, tile, standing-seam metal, membrane), because a kit that is rated for one covering and installed on another is the most common path to a leak call. Third, for electric-actuated units, confirm the actuator's IP rating, the rain/wind sensor package, and the control voltage — these three lines are where a US$135-per-m² fixed unit and an electric SKU part ways on the OEM's own Quick-View listing [S1].
The cross-check against the rest of the building package is the adjacent trades. Skylight pricing sits inside the same China-sourced aluminium and glass supply chain that feeds curtain-wall, pressure transmitter instrument enclosures, and HVAC louvre frames, so FOB-band moves on extrusions and tempered glass tend to land in skylight quotes within one quoting cycle. A 2026 buyer who tracks the Made-in-China index for aluminium-frame skylight SKUs is also tracking the input-cost signal for a meaningful slice of the building envelope — and that signal is the cleanest public leading indicator for whether a Q3 2026 re-quote will come in flat, up, or down [S1].
