VELUX: Roof windows, skylights, and EPD coverage

5 min read
Published: December 19, 2025

VELUX is synonymous with daylight from the roof. Their portfolio spans residential roof windows and sun tunnels to commercial rooflights and modular systems. For spec-driven projects that increasingly screen for verified environmental data, how well do those ranges come with EPDs today, and where are the quick wins to close gaps?

What VELUX sells

VELUX focuses on bringing daylight and ventilation through the roof. The residential line covers roof windows for sloped roofs, flat‑roof windows, sun tunnels, interior blinds, exterior shutters, and installation accessories. On the commercial side, they offer prefabricated flat‑glass rooflights, acrylic and polycarbonate domes, barrel‑vault continuous rooflights, smoke and heat exhaust units, and bespoke glazing panels.

Across sizes, glazing options, curb types, and control packages, the active SKU count sits in the hundreds. It is not a pure play in one product, rather a family that stretches from single residential units to large daylighting assemblies.

EPD coverage at a glance

VELUX publishes product‑specific EPDs that cover key families in both residential and commercial lines. In residential, that includes PUR‑framed roof windows in double and triple glazing, flat‑roof windows, and select blinds and shutters. In commercial, multiple dome, curb, barrel‑vault, modular rooflight, and glazing panel configurations are covered. These EPDs are third‑party verified and typically issued under European operators recognized by global programs, such as IBU and Smart EPD, aligning with EN 15804.

In plain terms, coverage is decent across the board and in the dozens. For teams bidding on projects that expect Type III declarations, that already lowers friction at submittal.

Where coverage looks thinner

Two areas appear less consistently represented by current, product‑specific EPDs. First, sun tunnels and other tubular daylighting devices. Second, classic wooden‑frame roof windows that are still common in heritage and residential renovation. We could not locate a current public EPD for those two examples in late 2025. If these are among best sellers in certain markets, that is a practical gap to close fast.

The competitive set on projects

On pitched roof windows, the most frequent competitors are Fakro and Roto Frank. Both publish product‑specific EPDs in core window lines, which can make life easier for project teams comparing like for like. On commercial rooflights and continuous systems, Kingspan Light + Air is a regular alternative. For tubular daylighting, Solatube shows up on many specs in education and healthcare. When your product lacks an EPD and theirs has one, the project team often has to apply conservative default factors in carbon accounting, which nudges selection away from you even if price and performance match.

A quick win example

If a wooden‑frame roof window or a high‑volume sun tunnel is among your top movers, prioritize a product‑specific EPD there first. Choose the same PCR family your closest rivals use so comparisons land apples to apples, confirm the program operator that best fits your target market, and design the LCA data pull around a clean 12‑month reference year. Even a single high‑runner EPD can unlock dozens of bids where LEED v5 oriented clients filter for verified declarations.

What specifiers want to see

They want credible declarations, clear declared unit definitions, and an issue date far from expiry. Age matters less than validity. Accessory coverage helps too. Flashings, upstands, and common shading kits round out the system so the submittal package feels complete rather than piecemeal.

Sustainability signals that reinforce the story

VELUX reports 100% documented renewable electricity across the group, and a 60% reduction in scope 1 and 2 emissions from 2020 to 2024 (VELUX Goals and Progress, 2025) (VELUX Goals and Progress, 2025). Their sustainability hub outlines climate, circularity, and biodiversity commitments with ongoing progress updates (VELUX Sustainability, 2025) (VELUX Sustainability, 2025). These signals do not replace an EPD, yet they backstop a credible materials narrative during value engineering.

Commercial takeaway

VELUX already covers many high‑leverage SKUs with EPDs, especially in flat‑roof windows, PUR roof windows, and commercial rooflights. The notable opportunity is to add product‑specific EPDs for sun tunnels and any wooden‑frame roof window best sellers to avoid losing spec on projects that score EPDs in pre‑bid checklists. Start with the one or two SKUs that drive most revenue, pick the prevailing PCR, and ruthlessly simplify data collection so engineering time is not stuck in spreadsheets. Teams that do this tend to recieve more shortlist invites, not fewer.

Frequently Asked Questions

Which VELUX product families most clearly have EPDs today?

PUR‑framed roof windows, flat‑roof windows, select blinds and shutters, and several commercial rooflight systems have product‑specific, third‑party verified EPDs.

Are sun tunnels covered by product‑specific EPDs?

We did not find a current public EPD for VELUX sun tunnels in late 2025. Prioritizing one would remove friction on LEED v5 projects and public bids that filter for EPDs.

Who are VELUX’s main competitors in EPD‑visible categories?

Fakro and Roto Frank for roof windows, Kingspan Light + Air for commercial rooflights, and Solatube for tubular daylighting.

What should a manufacturer prioritize when launching new EPDs?

Pick the highest‑volume SKUs first, align to the same PCR family used by top competitors, choose a recognized program operator for your target market, and plan a clean 12‑month data window for the LCA.
