Skylights — VELUX Authorized Supplier in California
VELUX Skylights — Fill Your Home With Daylight, Not Just Light
Western Window & Door supplies the full range of VELUX skylight systems — fixed, venting, solar-powered, and flat roof — for homeowners, contractors, and builders across Northern California. The world's most trusted skylight brand, sourced right here in Vacaville.
There's a Difference Between a Room That Has Light and a Room That's Alive
A vertical window borrows light from the side. A skylight pulls it straight from the sky — up to two and a half times more light per square foot than a standard wall window, falling from above the way sunlight was always meant to reach us. It changes the feel of a room in a way no lamp, fixture, or window placement can replicate.
But a skylight is only as good as the engineering behind it. A poorly made or incorrectly installed skylight leaks, fades, overheats in summer, and becomes a regret within a few years. A VELUX skylight — installed with the right flashing system on the right roof — is backed by an industry-leading warranty, engineered for California's climate, and designed to perform for decades without a second thought.
At Western Window & Door, we supply the complete VELUX skylight lineup. Whether you're bringing light into a dark living room, adding ventilation to a stuffy kitchen, or speccing skylights across a new construction project, we'll help you find the right product, the right size, and the right configuration for your roof.
Why VELUX? Because 80+ Years of Innovation Isn't Accidental.
VELUX is the market leader in the manufacturing of skylights and roof windows — a company that has always been a little bit ahead of its time in innovation, quality, and craftsmanship, holding over 2,000 patents and unique designs.
Every VELUX skylight is made from glass, composite materials, and 50% recycled aluminum — built for durability, with many lasting up to 30 years.
VELUX skylight systems are continually improved in pursuit of brighter, healthier spaces — engineered for performance, with rigorous testing and quality control measures ensuring they withstand harsh environments and extreme weather, from heavy rainfalls to strong winds to sweltering heat.
And the warranty backs it all up. VELUX stands behind their skylight systems with an industry-leading 10-year installation warranty, plus 20 years on glass, 10 years on product, and 5 years on shades and controls — with coverage on leaks, hail, and product defects.
The No Leak Promise — Three Layers of Protection, One Commitment
The number one fear with skylights is leaking. VELUX's engineering addresses this head-on with a patented three-layer water protection system built into every deck-mounted and curb-mounted installation:
Layer 1
Pre-Attached Seal
Blackout blinds reduce light penetration by 98% when in use — ideal for bedrooms or media rooms where total darkness is needed. Available in manual and solar-powered remote-controlled versions.
Layer 2
Adhesive Underlayment
Adhesive underlayment provides secondary water protection against the harshest weather conditions — a critical layer in California's winter rain season.
Engineered Flashing
Layer 3
Engineered flashing provides easy installation and primary water protection — available in configurations for every roof type including shingle, shake, slate, tile, and metal.
The result is VELUX's No Leak Promise: when installed with the correct VELUX flashing system, your skylight is covered by a 10-year installation warranty against leaks. That's not marketing language — it's a written commitment.
The VELUX Skylight Lineup — Every Configuration, Every Roof
VELUX offers one of the most comprehensive skylight ranges in the industry. Here's how the product types break down:
1. Fixed Skylights — Pure Light, No Moving Parts
1. Deck-Mounted Fixed (FS) - The cleanest, most streamlined skylight option available. With a slim and streamlined aesthetic, VELUX fixed skylights maximize daylight in the home while complementing the look of the roof. Installed flush into the roof deck, these sit low-profile and deliver consistent, beautiful daylight without ventilation — ideal for living rooms, dining areas, stairwells, and any space where you want maximum light with minimum visual interruption.
Standard laminated glass features an advanced Low-E protective coating, dual-sealed and injected with argon gas for increased protection and indoor comfort with clean, clear views and exceptional durability. Available in 14 standard sizes.
2. Curb-Mounted Fixed (FCM) - VELUX curb mount skylights work in just about any application — designed to mount on top of a site-built curb, they accommodate flat, low-slope, or standard slope roofs and work with shingles, shakes, slate, tile, metal, and more. The FCM is also the easiest replacement path for old plastic bubble skylights — it drops right onto an existing curb without tearing up and repairing the surrounding roof.
The curb-mounted design reduces unwanted outside noise by up to 25% compared to standard double pane glass, and up to 50% compared to a plastic skylight. Available in 17 standard sizes plus 19 custom sizes.
2. Venting Skylights — Light and Fresh Air Together
1. Solar-Powered Venting (VSS / VCS) - The flagship of the VELUX lineup — and the smartest investment for most California homeowners. The solar-powered fresh air skylight features a solar panel that captures available daylight and uses it to recharge a highly efficient, fully concealed battery-powered operator and control system — the battery opens and closes the skylight, with a built-in rain sensor that automatically closes the unit in the event of inclement weather, even when you're not home.
The battery will charge even on cloudy days or in partial shade — and the skylight can be opened day or night since it runs on stored battery power, not live solar input. Operated by wireless remote, no electrical wiring required.
The practical benefit in a California home is significant. Many VELUX skylight models are designed to open and close, allowing fresh air to circulate — proper ventilation helps prevent moisture buildup, reducing the risk of mold and improving indoor air quality. For rooms that tend to feel stuffy, like bathrooms or kitchens, a ventilating skylight can be a great way to let fresh air flow in.
2. Electric Venting (VSE / VCE) - For projects where hardwired power is preferred. Same venting functionality as the solar models — remote-operated, rain-sensor equipped — with a direct electrical connection instead of a solar panel. Available in deck-mounted and curb-mounted configurations.
3. Manual Venting (VS / VCM) - The accessible, budget-friendly venting option. Operated by a telescopic control rod, manual venting skylights bring fresh air in at the turn of a handle — no power, no batteries, no electronics. Straightforward, reliable, and priced for projects where simplicity is the priority.
3. Flat Roof Skylights
Not all California homes have pitched roofs. VELUX's flat roof skylight range covers low-slope and flat roof applications that standard deck-mounted or curb-mounted products can't handle:
GSM Fixed SkyMax : Fixed flat roof glazing for maximum overhead daylighting on low-slope roofs.
FXG Fixed Double Dome : Double-dome acrylic construction for durability and insulation on flat applications.
CXP Hatch : A polycarbonate dome top cover with hatch functionality — useful for roof access combined with daylighting.
4. Self-Flashed Skylights (EVMS / EV / EF)
A lightweight, economical option for simpler residential applications. The self-flashed design simplifies installation and reduces cost — available in solar-powered, manual venting, and fixed configurations. A good fit for replacement projects and straightforward new construction.
Glass That Works as Hard as the Skylight Around It
VELUX's glass technology is a significant part of what separates their products from generic skylights. Every model comes with high-performance double-pane Low-E argon glass as standard — but there are upgrades worth knowing about:
Standard Laminated Low-E3 Glass — Clean, quiet, and safe — features an advanced Low-E protective coating, dual-sealed and injected with argon gas for increased protection and indoor comfort. Building codes require laminated glass for out-of-reach applications, and VELUX includes it as standard on deck-mounted models.
Neat® Glass Coating — The smoothness of this unique material reduces water spotting and helps water disperse and evaporate more evenly. It also reduces outside noise by up to 25% compared to standard double pane skylights, and up to 50% compared to a plastic skylight.
Impact Glass — For coastal installations, high-wind zones, or simply peace of mind. Engineered to meet impact rating requirements in applicable building codes.
Snowload Glass — Reinforced for roofs subject to heavy load conditions.
White Laminated Glass — For applications where diffused, privacy-forward light is preferred over clear views.
Built-In Shade and Control — Because Light Needs to Be Managed, Not Just Added
All new VELUX skylights come with pre-installed, white, solar-powered shades, offering built-in light control right out of the box. This is a significant value — shades that were previously a costly add-on are now standard.
Blackout Shades
Blackout blinds reduce light penetration by 98% when in use — ideal for bedrooms or media rooms where total darkness is needed. Available in manual and solar-powered remote-controlled versions.
Light Filtering Shades
Light filter blinds allow about 30% of light through — designed for kitchens or living rooms where total darkening is not needed but glare control is appreciated.
VELUX ACTIVE with Netatmo
VELUX ACTIVE automatically adjusts airflow using built-in sensors and a connected weather station, opening slightly for fresh air adjustment while preventing unwanted temperature loss — and working with your home's air conditioning system to keep comfort balanced. Fully smartphone-controlled, it takes the thinking out of managing your skylights entirely.
What Changes When You Add a Skylight
A well-placed skylight does more than most people expect. Here's what our California customers consistently report after installation:
More Light, Less Electricity
A 2'x4' skylight lets in more than 2.5 times the amount of light of a vertical window and can generate the equivalent lumens of up to 11 100-watt lightbulbs. For rooms where lights were running all day, the savings on electricity bills become noticeable quickly.
Better Air Quality and Ventilation
A stuffy home is a breeding ground for multiple respiratory irritants including bacteria, dust mites, pet dander, pollens, and molds. A VELUX venting skylight offers a viable alternative by enabling fresh air to naturally cleanse the indoor air of these micropollutants.
Real Health Benefits
Natural sunshine provides numerous health benefits, including boosting Vitamin D absorption and improved focus, memory, and productivity. For rooms where people spend the most time — kitchens, home offices, living areas — this matters more than most homeowners realize.
Higher Home Value
A home filled with natural light and good airflow feels more open, welcoming, and comfortable — qualities that add to the value of your home if you decide to sell. Bright, well-ventilated spaces are attractive to buyers, especially in rooms like kitchens, bathrooms, and family rooms where people tend to spend the most time.
Sustainable Design
VELUX is committed to sustainable manufacturing practices — every skylight comes with an Environmental Product Declaration (EPD) detailing where materials are sourced and how products are packaged and shipped. For homeowners and builders pursuing green building goals, VELUX skylights can contribute to LEED certification and other sustainability standards.
Solar-Powered Skylights May Qualify for a Federal Tax Credit
Solar-powered VELUX products — including the VSS and VCS fresh air skylights, and manual or fixed skylights with factory-installed solar-powered shades — may qualify for a federal residential energy tax credit. Qualifying VELUX products purchased and installed by December 31, 2032 may be eligible for a 30% credit on both the product and installation cost.
Important note: VELUX recommends that consumers always seek professional tax advice when making a final determination on any individual tax credit qualification. We can provide the product documentation needed — but please consult your accountant or tax professional to confirm eligibility for your specific situation.
Where a Skylight Makes the Biggest Difference
Living Rooms & Great Rooms — The single biggest transformation. A living room with overhead daylight feels fundamentally different — larger, warmer, more inviting. Position matters here: we'll help you identify the right roof location for your specific floor plan.
Kitchens — Where you spend the most active time in your home. A venting skylight in the kitchen solves two problems at once — flooding the work surface with natural light while exhausting cooking heat, steam, and odors without running the range hood constantly.
Master Bedrooms — A solar-powered venting skylight with a blackout shade gives you the best of all worlds: dark when you need to sleep, sky-gazing when you want it, and fresh air whenever you want it — all controlled by a remote from the bed.
Bathrooms — Privacy without darkness. A skylight brings natural light to a bathroom without any window required — and a venting model handles humidity that leads to mold and deterioration far better than an exhaust fan alone.
Home Offices — Natural light can boost energy up to 24% — in the workplace, this has been shown to decrease absenteeism and increase productivity significantly. A home office with overhead daylight is simply a better place to work.
Stairwells & Hallways — Often the darkest, most neglected spaces in a home. A fixed skylight above a stairwell floods multiple floors with natural light and creates a dramatic architectural moment with relatively simple installation.

FAQ's
Will my skylight leak?
VELUX skylights are engineered with three patented layers of water protection — a pre-attached seal, adhesive underlayment, and engineered flashing — backed by a 10-year installation warranty that covers leaks when installed with VELUX flashing. The right flashing kit for your specific roof type is the critical piece — we'll make sure it's specified correctly.
What's the difference between a skylight and a sun tunnel?
A skylight is a full glass unit installed in an opening cut through the roof — it provides a view of the sky, maximum natural light, and optionally ventilation. A sun tunnel is a tubular system that channels light through a reflective tube and is ideal for rooms where a skylight can't be placed directly, like interior bathrooms or hallways. Both are VELUX products — which one fits your space depends on the room's location and your roof structure. We carry both and can help you determine the right solution.
How much light does a skylight add?
A 2'x4' skylight lets in more than 2.5 times the amount of light of a vertical window of the same size, and can generate the equivalent illumination of up to 11 100-watt lightbulbs.
Do I need a venting skylight or is fixed enough?
Fixed is simpler, more affordable, and perfectly suited to rooms where light is the only goal. Venting skylights add fresh air circulation — worth the investment for kitchens, bathrooms, bedrooms, and any space that tends to feel stuffy or accumulate moisture. Solar-powered venting is the most popular choice because it requires no wiring and includes a rain sensor.
What roofs can VELUX skylights be installed on?
VELUX curb mount skylights will work in just about any application — it doesn't matter whether you have a flat, low slope, or standard slope roof, or what type of roofing material you have: shingles, shakes, slate, tile, metal, and more. Deck-mounted models are designed for pitched roofs with specific pitch ranges. We'll match the right product to your roof during the quote process.
Can I control the skylight from my phone?
Yes — with the VELUX ACTIVE system, solar-powered venting skylights and solar-powered shades can be controlled from anywhere via smartphone app. The system includes weather sensors that automatically adjust your skylights based on temperature, humidity, and rain data.
