VELUX Roof Windows

Professional Supply & Installation — Done Right, From the Inside

At Just Lofts & Build, we don’t just fit windows—we deliver a complete VELUX service. We supply and install genuine VELUX roof windows with precision, usually working entirely from inside your loft (subject to survey). That means no expensive scaffolding, minimal disruption, and a faster, cleaner installation. Whether you’re upgrading tired units or fitting brand-new ones, we make sure your home gets maximum light, ventilation, and energy efficiency from every window.

Where We Fit VELUX Products

We install across converted loft rooms, extensions, barns and outbuildings, unconverted loft spaces, bathrooms, kitchens, and bedrooms—wherever natural light and fresh air will make the biggest difference.

VELUX Sun Tunnels — Daylight Where You Never Thought Possible

Stop living with dark corridors and gloomy bathrooms. VELUX Sun Tunnels channel natural daylight from your roof straight to your ceiling through a highly reflective tube, transforming even windowless areas into bright, welcoming spaces without major building work.

Domed Rooflights — Robust, Stylish, Flooded With Light

When a flat glass skylight won’t do, domed rooflights step in. Available in a range of sizes, shapes, and glazing options, they bring in more natural light—even in awkward locations—while offering optional ventilation to keep air fresh and built-in UV protection for long-term comfort and durability.

Why Choose VELUX—and Why Choose Us

VELUX is the global leader in roof windows, flat-roof windows, sun tunnels, and blinds. Their products are built to last, deliver outstanding energy performance, and look good for years. We’re experienced installers who turn up when we say we will, work cleanly, and finish to VELUX standards—no cowboys, no shortcuts.

Brighten Your Home. Increase Its Value.

A correctly installed VELUX window or sun tunnel lifts your daily life, reduces energy costs, and increases property value—future-proofing your home with quality you can trust.
