Hinged either on the left, right, or from the top, they can be easily adjusted for the best ventilation
Clip-on Georgian bars, decorative glass and run-through sash horns are available

Casement windows are attached to the frame by one or more hinges on either the left or right side, so whether it’s open or closed it is permanently bolted into the space, unlike the vertical sash design. They can also be hinged at the top. As casement windows have no meeting rail, they offer a versatile number of outwards opening mechanisms, both horizontal and vertical. This makes them an ideal replacement window solution that can fit any niche shape or space.
Casement windows are the most versatile window style, fitting perfectly into any home regardless of its style and age.
Thanks to the streamlined design, casement windows are considered one of the most energy efficient window styles around.
Featuring locks embedded into the frame, casements add an extra level of security as they can't be picked or drilled from the outside.
Casement windows have no obstructive sections, so you can look forward to the best viewing experience possible.
Achieve superior airflow and natural ventilation with casement windows that open wide to let the fresh air in.

Glazing
Our upvc and aluminium windows come with EcoMAX Glass™, the most eco-friendly glass window unit on the UK market, as standard. Almost 100% biodegradable, it performs on par with typical A rated windows. You can upgrade to our Comfort Glass option, designed to outperform triple glazing thanks to the inclusion of a tough laminated layer and an effective low-e coating. You can also personalise your new casement windows further with our range of textured and patterned glazing for added privacy or decoration.
The benefits of upgrading your glazing are truly limitless - the most notable features include increased warmth, reduced energy bills & beating future energy price hikes. For complete peace of mind, we also offer toughened glazing options to enhance your home security further.
Frame Options
We have a number of distinctive styles of frame to choose from. The chamfered option is a contemporary, straight-edged style while the ovolo option provides a more traditional, decorative finish. Our flush option sees sashes that finish flush with the external face of the window.

Casement windows are one of the most versatile window options. You will have the ability to choose the colour, shape, size, material and hardware for a solution that complements your home. You can even specify in which way they open, to maximise ventilation and privacy. We offer both Bevelled (flat) and Ovolo (curved) frames, ensuring a style that can suit both modern and older properties.
Depending on whether you opt for uPVC or aluminium frames, you could have the choice of over 150+ RAL colours. Kent homeowners have recently favoured contemporary grey, classic white and woodgrain effects. Casement windows can also be designed in dual-colour options, so the inside and outside finishes can be completely different for a truly distinctive design. We can include any of our decorative glass options, including stained glass or etched glass, to add a unique touch to their design, with accompanying window furniture to finish the appearance.
Whichever casement window design you decide upon, installing new windows will increase the value of your home. This makes it an excellent choice should you want to sell or invest in the future.
Get A PriceuPVC casement windows are one of the most cost-effective choices for new windows, this is because modern uPVC can be easily manufactured with streamlined processes nowadays. Although, the lower price tag doesn’t mean that it compromises on performance. Our advanced uPVC window profiles use a multi-chambered system, meaning it traps the heat inside and stops cold elements from entering, ensuring a comfortable temperature inside. They can last for at least 35 years without needing any maintenance, and won’t rot, warp or fade, thanks to a protective outer coating.
With uPVC casement windows, the design options have no limit! They can be finished in over 150+ RAL colours and a number of authentic woodgrain finishes, so they can easily achieve both a contemporary style and a traditional aesthetic.
uPVC Casement WindowsHigh-performance aluminium casement windows offer distinctively thin framed designs that no other material can achieve. The slim-framed appearance will effortlessly add a modern aesthetic to any home, whilst letting in more natural light for a brighter room. It also means you can benefit from greater views of the outdoors.
Our ultramodern aluminium windows use a thermally broken profile which breaks up currents of air, resulting in exceptional thermal performances. This innovative design also helps to keep external noises out of your home. The powder-coated frames are finished in an anti-fade coating, keeping them looking like new for over 45 years. They don’t require any maintenance, so they’re an ideal solution for busy homeowners.
You can choose from 150+ RAL colours and a variety of woodgrain effects depending on your personal tastes. With their uniquely smooth frames, they’ll add kerb appeal to your home.
Aluminium Casement WindowsOur double glazing and comfort glass options will all heighten the thermal performance of the window. Double glazing and comfort glass designs use advanced glass panels that surround argon-gas filled chambers which eliminate energy wastage.
A window upgrade is an excellent way to improve your home’s environmental impact as you’ll need less energy to warm it up, and you’ll also see reductions in your heating bills. Depending on your chosen style and material, A+ energy ratings can be achieved. We incorporate a number of features to maximise their thermal abilities, including warm edge spacer bars and beaded frames, ensuring that the heat is unable to escape from the room, and draughts won’t be able to enter for a comfortable interior all year round.
Get A PriceProtect your loved ones and belongings with our modern casement windows. We fit them with either state-of-the-art multi-point locking systems or shootbolt locks, both of which have been stringently tested to relevant security standards. If you’re looking for even greater peace of mind, we can include additional security features into your new window specification.
Casement windows are also highly durable. In terms of weather protection, they won’t be beaten. They provide airtight protection when closed and have undergone rigorous testing for wind and rain resistance. Regardless of the conditions outside, they’ll continue to perform like new for many years to come without weakening or reducing performance.
