Premium Roof Glazing – Fabricated for Fast, Flawless Fitment

Flat roof windows are a popular addition in new-build conservatories and refurbishment projects. At Premier Frames, we fabricate flat glass rooflights that deliver the ideal combination of thermal performance, aesthetics, and installer-friendly design, helping you work efficiently while exceeding customer expectations.

Our flat roof window systems are designed with installers in mind: no site cutting, no drilling, and minimal installation time. Whether working on a brand-new Ultraframe conservatory or retrofitting to an existing extension, our systems arrive ready to fit, helping you get the job done quickly and professionally.

Why Fit Flat Roof Windows from Premier Frames?

We understand what matters to installers: reliability, flexibility, and glazing systems that go in without a hitch. Here’s what you can expect when you choose our flat rooflights:

Fabricated for Speed

Our rooflights are made to measure in-house and delivered fully assembled, allowing you to eliminate time-consuming on-site preparation work. No mess, no delays, just install and go.

Ideal for New Builds and Replacements

We supply many installers working on new-build Ultraframe conservatories, but our roof systems are also fully compatible with conservatory roof replacement projects. Tap into the retrofit market and expand your customer base with ease.

Superior Daylight and Ventilation

Flat roof windows open up spaces with an influx of natural light, making rooms feel brighter, bigger, and more inviting. Optional opening configurations also provide improved airflow, making them ideal for kitchens, bathrooms, and other high-humidity areas.

Thermally Efficient, Built to Last

Every rooflight we fabricate meets high standards for insulation and strength. Choose from dual-pane (1.2 W/m²K) or triple-pane (0.7 W/m²K) glass, with argon gas fill and Thermal Super Spacer® as standard. Our thermally broken aluminium frames are powder-coated in Anthracite Grey (RAL 7016), with other RAL colours available on request.

Flat Glass Rooflights – Tailored to Your Project

We offer multiple rooflight styles to suit your installation needs, whether you’re prioritising quick fitment, a clean finish, or ventilation performance.

Framed Flat Rooflights: Featuring robust, visible frames, these rooflights offer added structural strength, making them ideal for exposed locations or larger spans.
Frameless Flat Rooflights: A seamless glass finish, without visible borders, delivers a minimalist, high-end look that your clients will love—perfect for contemporary extensions.
Fixed Rooflights: Focused solely on light transmission, fixed flat roof windows are a go-to for projects where natural lighting is a priority but ventilation isn’t needed.
Opening Flat Rooflights: Combine light and ventilation with our manually or electronically opening units—ideal for functional rooms like kitchens and bathrooms.
Walk-On Rooflights: Our reinforced walk-on models combine safety with stylish overhead glazing for terraces, balconies, and commercial projects.

Fixed Rooflights: Installer-Friendly and High Spec

Our most popular option for conservatory builds and retrofits, these flat rooflights come pre-fabricated for effortless installation.

Why Choose Premier Frames

Better Products

Premier Frames work exclusively with market leaders Ultraframe to fabricate and supply conservatory components for installers.

Over 2 million Ultraframe products have been installed nationwide, making it the most popular conservatory frame in the UK. They are known for offering homeowners superior levels of thermal efficiency and home security. The installation process is also incredibly straightforward for you as the installer. Our products come ready assembled and have simple two or three step fittings.

Better Relationship

We have a great relationship with Ultraframe, having recently chosen to work exclusively with them rather than using multiple suppliers.

By having such a good relationship, we can ensure that the products we supply are consistently of a high standard. All of these conservatory and extension components are manufactured here in the UK, which allows us to have a better control over what we’re supplying to our network of installers. As a result, we’re able to provide those installers with market leading conservatory and orangery roof systems.

Better Service

We take pride in delivering a friendly, personal service to all the installers we work with. We’re able to offer help and support whenever required.

As the installer, you’ll have two options with receiving your Ultraframe products. You’ll be able to choose between collecting from our showroom or having the components delivered. We’re located in North East Leicester, near the A47. If you’re looking to have the products delivered, it typically takes around ten working days. Our friendly team will handle the delivery or collection professionally.

Better Coverage

Based in the East Midlands, we have customers spread across the middle of England. We’re continually looking to expand our catchment area.

Although we primarily work with installers local to us in the East Midlands, we have previously supplied to companies as far and wide as Margate, Chippenham and Stoke. As it stands, we don’t currently supply to Wales, Scotland or Ireland. Get in contact with Premier Frames if you’re unsure whether we can supply our Ultraframe roof systems to you. If the answer is yes, we can provide you with a quote.
