Maximise Daylight With Attic Windows

Fill your attic with an abundance of natural daylight and transform it into the brightest and healthiest room in the home.

More and more families are starting to reassess the current levels of natural daylight in their homes. This heightened awareness to the importance of regular sunlight exposure has been driven in large part by the hard-hitting VELUX Indoor Generation ad campaign.

The benefits of natural daylight and the dangers of a lack of it are now well documented. In short, insufficient sunlight can lead to tiredness, lack of productivity, illness and even depression.

Getting outside more often is the best and most obvious solution to this problem, and is easy and free to do. Many of us, however, forget this when glued to a TV series or book, or constantly travelling from home to work to gym to the shops.

This is where your home can help you. Increasing the amount of natural light coming into a building can ensure those inside it benefit from the sun at all times.

Light bulbs have for too long been a poor substitute for daylight. Not only do they not provide any of the natural goodness the sun does, they are also expensive, often unreliable and drive up bills.

Anybody with used/unused loft space or a pitched ceiling with an outside wall are in the perfect position to implement healthy, long-lasting changes with the installation of an attic window or two. (Scroll down to skip to a list of our favourite attic windows)

Attic windows, installed at either eye level or higher up in a roof, are one of the most effective ways of filling a room with natural sunlight, being hugely beneficial to anybody living, working or sleeping below.

Not only do attic windows bring superior health benefits thanks to an ability to transmit three times as much sunlight as vertical windows, they can also enhance a room's look and performance in several other ways.

views from an attic window

The lighting supplied by a well placed attic window can make a room feel more spacious, while also making it more energy efficient. Today’s best attic windows come with an argon filled double or triple glazed unit that helps keep heat trapped inside the home when it's cold outside. In the summer, low-E coated windows will help limit solar gain to help rooms stay cooler. 

Attic windows should be for all-year-round living. Aside from welcoming in more light and improving thermal performance, attic windows can provide panomaric views when installed in the loft and remove steam and food odours when installed in a kitchen or dining room.

To help you find the right attic window, we have complied a short list of some of our favourite (and most popular) attic windows sorted by four important categories; price, insulation, views and maintenance.

We hope you enjoy reading our list. All of these attic windows are available for free next day delivery at the best price online thanks to the Sterlingbuild price match promise.


RoofLITE attic windows

A cheap roof window does not have to mean a poorer window. Attic windows are available from industry leading names at prices more likely to keep you within budget.

RoofLITE pine centre pivot roof windows start from just £83, with modern white paint CORE models starting at £110. Despite these affordable prices, RoofLITE windows can fill a room with just as much natural light as competitor brands.

RoofLITE pine and white paint attic windows carry a better than average U-value of 1.5 W/m²K that confirms strong thermal performance. A sound reduction rating of 32dB also guarantees that your RoofLITE window will help drown out unwanted noise from outside.

RoofLITE, sister brand to VELUX, create all of its attic windows with FSC certified, rigorously tested pine. These attic windows come in a slimline frame that minimises framework in order to maximise daylight.

The energy efficiency of an attic window is best measured by its U-value. The lower the value, the more thermally efficient the window.

A U-value below 1 is particularly impressive and way ahead of average. With a U-value of 0.9, ECO+ pitched roof windows are thermally outstanding, yet still come at a price that belies such strong spec.

ECO+ attic windows come with triple glazing as standard to ensure that all units improve the energy efficiency of the room they're going in. All ECO+ centre pivot windows also have low-E coating treatment to ensure rooms to do overheat during warmer months, along with lockable handle positions to provide ventilation.

The triple glazed unit of ECO+ units are argon filled to help keep warmth trapped inside a room and reduce condensation, features which when coupled with the windows’ PVC frame, makes it a smart choice for kitchens and bathrooms.

For Passivhaus projects, Sterlingbuild’s lowest U-values can be found on solar roof windows from VELUX. Learn more about the power of solar windows here.


eco+ top hung roof windows

Made up of the same spec as ECO+ centre pivot windows (pictured), ECO+ top hung windows have the added benefit of being fully openable to provide unspoilt views.

Top hung attic windows have the capacity to bring even more natural light into rooms, while having greater ventilation capabilities too.

ECO+ top hung attic windows are ideal for eye level installation as the entirety of the sash exits the room to leave uninterrupted views for the lucky inhabitant when installed in the loft.

Although justifiably more expensive than centre pivot roof windows, top hung windows from ECO+ are perfect if you want to turn your loft into a room that is not only bright and well ventilated, but with views that make everybody want to come up and enjoy.

For a completely unique attic window that can switch into a Juliet-style balcony in seconds, discover the VELUX CABRIO and FAKRO Galeria.


We could list ECO+ here for a third category running given its low maintenance PVC frame, or the economical RoofLITE PVC DURO window, but no list would be complete without a VELUX on it.

The VELUX GGU has and always will be one of Sterlingbuild’s most popular roof windows and for good reason.

The VELUX GGU comes in a PU frame that is ideally designed for any rooms where steam and moisture are prominent, namely kitchens and en-suite bathrooms.

Just like ECO+ windows, VELUX PU attic windows have a self-cleaning exterior glass that will help keep the external pane free of dirt.

If and when your VELUX does need cleaning, the glazing can be rotated 180 degrees to allow safe and comfortable maintenance to be carried out, with special VELUX maintenance kits available for just the job.

As well as manual, the VELUX GGU comes in electric and solar operation for the ultimate in convenience.
