About Our Casement Windows
Casement windows are one of the UK’s most popular styles, offering practical use and a timeless style. Hinged at the side or top, they open wide for easy ventilation.
Made from high-performance frames and fitted with energy-efficient Planitherm glass, our casement windows are low-maintenance, secure, and built to last. They suit all property types across Lincolnshire, from modern builds to traditional homes.
Colours and Finishes
Our casement windows come in a wide range of colours to match your home’s style. Choose from classic white, warm cream, or woodgrain options like light oak and rosewood.
You can also opt for different colours inside and out, helping your new windows blend perfectly with your home's interior and exterior. All finishes are designed to last without fading or peeling.

Choosing the Right Casement Window Configuration
Casement windows can be designed with side-hung, top-hung and fixed sections, allowing the layout to suit the size and use of each room. A side-hung opening can provide wider ventilation, while a top-hung section can offer controlled airflow without taking up the full window area. Fixed panes can also be combined with opening sections where more glass and natural light are a priority.
During the survey, our team can help you consider ventilation, furniture position, access for cleaning and the appearance of the complete elevation. This makes it easier to select a practical configuration that also looks balanced from outside the property.
Reduce Your Heating Costs
Our casement windows are designed to help improve energy efficiency in your home. They’re made with modern uPVC or aluminium frames and energy-saving Planitherm glazing that helps retain warmth.
This thermal performance means your home stays more comfortable throughout the year, especially in winter. It can also help reduce your reliance on heating and lower your energy bills over time.
uPVC or Aluminium Casement Windows?
uPVC casement windows are a popular low-maintenance option with a broad range of colours and woodgrain finishes. Aluminium offers slimmer frames and a contemporary appearance, which can work particularly well where larger glass areas are wanted.
Both materials can be combined with energy-efficient glazing and secure hardware. The best choice depends on the property, the preferred frame proportions, colour, maintenance expectations and budget. Our team can show you both options at the Lincoln showroom before the final specification is agreed.
Perfect for Modern and Traditional Homes
Casement windows are a classic design that suits almost any property. Whether you live in a newbuild or an older home, they offer practicality and timeless style.

We asked Cliffside to replace our old conservatory including new foundation’s. We chose the solid roof option from Lela and had the interior plastered and the floor tiled, complete with under floor heating. All the staff a contractors were very professional and completed the works to a high standard. Communication with Cliffside was easy and any questions or issues we had were dealt with promptly.
We’re both absolutely delighted with our new room now being able to use it all year round. We would definitely recommend this company, thanks again Cliffside.
