Storm Casement Windows
Based in South Manchester, we are no strangers to the rain and understand the importance of protecting your home against unpredictable weather. Storm casement windows can offer all the beauty and timelessness of traditional casement windows but with the peace of mind of additional weatherproofing and thermal performance.
What are storm casement windows?
Often referred to as stormproof windows or lipped casement windows, storm casement windows don’t sit flush in the frame as the traditional casement style does. Instead, they have a lip that sits proud of the frame. This lip is simple yet effective in providing additional protection from the elements, giving them their stormproof name. Stormproof casement windows have an embossed look as opposed to a flush one for a slightly different aesthetic.
In the UK’s windy/rainy and often cold climate, stormproof windows offer extra weather resistance and better insulation. The lip makes it harder for water to find a gap and reduces heat loss from the frame, helping you to maintain a comfortable temperature in your home. They also offer some acoustic and security benefits.
First introduced to the UK in the 1950s, they have become a popular window style for British homeowners.
How do storm casement windows work against the weather?
Believe it or not, the weather helps to make these windows weatherproof. With outward opening windows, when there is pressure from the likes of wind, this pushes against the window surface. Because of the lipped casement in storm windows, this pressure only aids in pushing the sash more firmly against the seals it sits within, making less space for draughts to squeeze into.
Types of stormproof windows and frames
We offer a large selection of casement windows to suit any home. Our flush-fitting or stormproof casement windows are available in UPVC, aluminium, or timber to suit every taste and budget.
The material of the frame can significantly impact a window’s energy efficiency, durability, maintenance requirements and appearance.
UPVC Storm Windows
The most affordable type of stormproof casement windows, UPVC are low maintenance and offer good insulation. However, standard UPVC may not suit older properties. It is less sustainable than aluminium or timber, and you may find fewer design options. It also doesn’t last as long as its rivals, as it can crack or split with repeated weather exposure, and certain colours can fade over time. It is best for those on a budget looking for a shorter-term solution.
Aluminium Storm Windows
The most eco-friendly of the three materials, aluminium is infinitely recyclable and has a low manufacturing carbon footprint. It offers a sleek look with ultra-slimline frames available. It costs a little more than UPVC, but it arguably makes up for it with its durability. Aluminium also doesn’t require much maintenance but is strong and durable even when slimmed down. Aluminium is not naturally as good an insulator as UPVC, but adding thermal breaks to the window typically makes it match the insulation of a similarly rated UPVC window.
Timber Storm Windows
The most expensive option, timber offers an authentic appearance in your choice of sustainably sourced Meranti, Sapele or Accoya wood. Wood is an excellent natural insulator but is not as weather-resistant as UPVC or aluminium, especially if it is untreated. Wooden window frames can warp, rot or crack and require regular cleaning and sealing to protect against the elements.

It’s All in the Detail
Our casement stormproof windows offer several customisation opportunities, from your choice of glazing to the colour and finish of the frame, and ending with the handles and security features, you can create the windows that best suit your needs.
Window Handles
The finishing touches of a window are the handles, fixtures, and fittings. At Manchester Window Factory, we offer a collection of window furniture in various colours, from black and gold to brushed chrome.
Colour Choices
Choose stormproof casements with a smooth or grained effect, depending on your property style.
Available in a wide range of coloured foil finishes, including two-tone, your windows can be as striking as they are storm-busting.
Don’t let the rain stop you from having the whole rainbow. Classic white, black, or anthracite grey are timeless, while pretty pastels or bold brights help you put your stamp on the property.

Glazing
We also offer a large selection of glazing, from Planitherm low-E triple glazing to acoustic glass for noise reduction. For a more historical look, ask about our traditional leaded glass with stained glass and Georgian bar options.
Security Features
Stormproof casement windows are slightly more secure than the traditional flush style because there is an extra barrier between the window and a would-be intruder.
All our windows meet British Police security standards and have the most secure locking mechanisms available. You can take that a step further and integrate your windows into a smart home security system.

Storm Casement Windows FAQs
What Manchester Window Factory doesn’t know about windows isn’t worth knowing, so if your question isn’t answered below, our family-run business is here to help.
Yes. A French casement window, also known as a double frame, features two side-hung panels with a central mullion. The handles are central, with the window opening outwards to create a wide aperture.
Traditional flush windows are one of the most popular styles of window in the UK. Casements sit seamlessly within the window frame, resulting in a minimalist and elegant design, proven to be a timeless favourite.
Stormproof windows offer everything that a flush casement window can, with customisable colours and energy-saving glazing to fit your home and budget.
Visually, stormproof windows have a lipped casement, meaning that the windows are raised from their frame. This lip provides extra weather resistance and a more modern look. If you’re not sure which window will best fit your style, get in touch with our friendly team of experts.
Absolutely! We offer a range of materials (UPVC, timber, aluminium), colour choices, window handles, and glazing options to match your style and performance needs.
To replace all the windows in a standard 3-4 bedroom home with storm casement upgrades should take around 5-10 days. A single window can be fitted in one to two hours, depending on the ease of access and the complexity of the design. However, windows are typically fitted in small batches a day, so that you aren’t living with holes until the replacements are fitted.
