Two Replacement Windows
Had 2 windows replaced due to previous windows causing damp issues. The team were very polite and incredibly knowledgeable. I can't believe the difference with the new windows. The quality is amazing. Will definitely be using the company again to replace more windows and have already recommended to family and friends.

New Cottage Windows
Had some windows fitted in my air bnb cottage. The guys did a great job. I had the old style with the wood dividing the panes of glass and they look amazing so in keeping with the cottage style. Everything was left spotless. Would highly recommend Optimus and will definitely be using them again. Thanks Optimus

Optimus casement windows are available in a wide range of configurations, styles and finishes. We can design and install single casement, double casement, top hung, fixed casement and tilt and turn windows. We have provided some more detail on these windows below.  Our uPVC casement windows make a bold statement with their low sightline gaskets and neat finish, allowing you to relish the uninterrupted views from inside your property. Spacer bars fitted within provide extra strength against condensation and cold air ingress for added protection – perfect for helping maximise natural light entry.


Factoring in popularity, convenience, and versatility, the single casement double-glazed window is a top contender in the window game. With a simple yet effective design consisting of one hinged window opening along the side, you can control the airflow as much or as little as you desire. This type of window can complement any architectural style, whether it’s a modern build or a historic home, making it a reliable and timeless choice.


Looking for a window that can seamlessly merge your indoor and outdoor spaces? Look no further than double casement windows, or French Windows. These windows boast two sash windows that can be opened from the centre, obliterating any central bar obstacle. They provide the perfect, undivided view. Additionally they enable you to enjoy the fresh air without ever having to leave the comfort of your home.


Another excellent addition to your home  are top hung windows. These cool windows swing open from the bottom and are hinged at the top. They’re cleverly designed to hang from the top track, meaning the frame heads take most of the weight, making them durable and long-lasting. In addition to looking stylish, top-hung casement windows are great at blocking out rain, making them the perfect choice for any weather conditions.


Are you looking to add some natural light to your living space without the hassle of opening and closing a window? Look no further than a fixed casement window! These windows may look like their functional counterparts, but they’re purely decorative. They are designed to let the sun in and add a touch of elegance to your home. While they won’t provide any ventilation, their aesthetic appeal is unmatched.




Make your Plymouth home more energy and cost efficient with quality, hand-finished windows and doors. Our products will not only help you save on expensive monthly bills – they’ll also reduce noise pollution for a better living experience.


At Optimus, we believe in the quality and craftsmanship of British manufacturing. That’s why all our products are absolutely made with passion and pride right here at home – allowing you to be part of a movement that will help shape Britain’s future. Get on board today: Choose Quality; Choose British windows.


We are based in Plymouth although we cover a wide area outside of city including Manamead, Tamerton Foliot, Woolwell, Glenholt, Derriford, Bickleigh, Roborough, Plympton, Chaddlewood, Hemerdon Sparkwell, Luton, Brixton, Yealmpton, Noss Mayo and Newton Ferrers to name but a few!


Our selection of uPVC double-glazed windows ensures the safety, tranquility, and, above all, warmth of your home. We provide uPVC and aluminium windows in double-glazed or triple-glazed options, available in a variety of colours and styles to suit every home. Our range of doors caters to diverse needs, including French Doors, Sliding Doors, uPVC doors, Solidor Composite Doors, and more. Additionally, we offer the supply and installation of elegant and impressive Aluminium doors, all available in a extensive array of colours.


Our casement windows are a multi-chambered uPVC  profile design. This state-of-the-art profile enables them to achieve an A+ rated standard of heat retention. At a time when energy bills are high this rating means that they will work to keep your home comfortable throughout the cold winter months and trap in warmth to support your Plymouth property to heat up more quickly. It will also reduce heat loss through the windows and enable the house to stay warmer for longer.


With Optimus casement windows in place, you could save money on your heating costs as your boiler wont have to work as hard to keep your home warm, or you wont need to rely as much on the grid if you have solar panels and battery storage. Consequently, you could find that your heating costs or carbon footprint reduce.

You can customise the appearance of your new uPVC casement windows with a range of finishes, colours and hardware. Classic white will always be popular, but you can also select from a choice of RAL colours to suit your home, and the woodgrain finish is always popular with our cottage-dwelling customers.

Because every house is different, windows have to be bespoke. A customer living in a modern new build home will often select something very different from a traditional or heritage property. At Optimus, we pride ourselves on being able to bring a personal touch to your window without compromising on quality and offer our Plymouth customers a wide choice to meet all their wants and needs.

We are confident in the quality of all our products, and we acknowledge that replacing windows is quite an investment in terms of home improvements. With this in mind, our casement windows come with a 10-year insurance-backed guarantee through Assure. Assure not only provides a guarantee but verifies that your casement windows are the energy-rated ones you ordered and that the installers and surveyors hold the appropriate qualifications, giving you peace of mind.
