Top -hung casement windows have hinges at the top and open from the bottom of the frame — meaning they (mostly!) keep out the rain if you leave them open. Side-hung windows offer superior ventilation (they can be angled sail-style to direct a breeze indoors) and are easy to open and close.

Casement windows are possibly our most popular make of window and are manufactured to your exact specifications in our state-of-the-art factory before being fitted by our team of expert engineers.

Frequently Asked Questions

What’s the difference between a casement window and a picture window?

Casement windows are attached to the window frame by a hinge and can be opened to allow fresh air to circulate around your home. Picture windows, on the other hand, are designed to allow for a beautiful panoramic view of your outside space.

Whilst casement windows are usually quite small, consisting of multiple sashes or panes, picture windows are made up of far fewer window panes, which offers an improvement to your outside view. However, picture windows are fixed in place and can’t be opened.

Are casement windows secure?

About as far as secure as any window can be! Our casement windows come with specially designed hook-shaped locks that fit directly into their frame, making them very difficult to break into from the outside. Should an intruder try to pry them open, casement windows make it difficult to do so. Our commonly-fitted multi-locking system can add another element of protection.

Launa’s casement windows have the additional benefit of being certified by the Official Police Security Initiative. We hope this lets you and your loved ones feel safer.

Are casement windows worth it?

Casement windows can create a bright, airy space, giving your property a refreshing ambience and improving your enjoyment of your home. They’re also excellent insulators thanks to our compression seal technology, which we hope will help you save on your energy bills.

Finally, casement windows are often the window of choice for those with limited mobility: they can be fitted with a geared crank mechanism that opens and closes the window, requiring little effort. Very often, casement windows can be readily opened and closed with one hand.
