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

Highly Recommend this company
Highly recommend this company, for the initial quote Chris turned up on time, talked us through all options, and some we had not even thought of, very knowledgeable with no hard sell. The fitters Tim and John turned up at 8.30 everyday, worked hard and we are so pleased with their fitting and the end product Many thanks to you all

Faultless from Start to Finish.
What a great experience. From beginning to end our dealings with Optimus have been a delight. Nothing was too much trouble for them. From the original and ongoing messages with Chris, the survey with Tim, and the fitting with Jon and Tim (with a guest appearance from Chris!) everything was a pleasure.

I love my new door and window!
Great and very stress-free experience with Optimus. I love my new door and window. The door fitting was delayed due to the door not passing the quality check initially but a new date was quickly arranged. I felt comfortable having Jon and Tim at the house and they just got on with the work without any issues. Would certainly recommend.

Very professional
Dealt with Chris the owner who was helpful from start to finish. Didn't push the sale & nothing was too difficult. Fitters were also very professional & the workmanship was second to none. Great experience & glad I opted for a local business in Oreston. Recommended.


Our uPVC sliding sash windows benefit from modern technology, engineering and manufacturing methods. They are robust yet stylish, and their modern spring balance mechanism makes them easy to open and close, unlike their timber predecessors.


Traditional Wooden Sliding Sash windows are single glazed, so noise travels quickly from outside to inside homes. uPVC sliding sash windows come with double or triple-glazing options to keep the outside noise out. Adding more panes of glass prevents more of the energy of the sound wave coming into your home and therefore reduces noise pollution.

uPVC Sliding Sash Window FAQs


Our high-performance, multi-chambered profile works together with the specialist uPVC sliding sash weather seals to keep the elements out. They will protect your Plymouth home from the wind, the rain and the cold and keep it comfortable in the summer months.
A rated Sliding Sash Windows for your Plymouth home
Optimus sliding sash windows are thermally efficient to an "A" rating and could help lower your heating costs. "A" rated windows help retain more of the heat your central heating produces, so your boiler doesn't have to work as hard to keep your home warm.


Our uPVC Sliding Sash windows come in a range of styles and finishes. We have a range of glass options, including decorative glass. You also have the option of Georgian or astragal bars to complement your windows. All our Plymouth uPVC sliding sash windows come in a range of colours, too; please get in touch with us for the full range of colours and woodgrain foils.


Optimus knows there are 5 clear benefits in installing uPVC sliding sash in your home. The first is that the windows will enhance the look of your Plymouth home. Therefore giving it more kerb appeal. The second benefit is the reduced need to maintain your windows consistently; you only need soapy water and a sponge. The next benefit is the thermal-efficiency; not only could this reduce your heating bills, but it could also reduce your carbon footprint. The fourth benefit is the improvement in weather protection; sometimes, the British weather can test even the best of windows, and you will find that your uPVC sliding sash windows will stand up to the harshest weather conditions. Lastly, and some would say most importantly, is the improvement in home security that these uPVC windows bring. All our windows are "Secured by Design" to give you peace of mind.


The Sliding Sash Windows that we supply and fit have gone through extensive energy rating simulations from the British Fenestration Ratings Council (BFRC) simulator. To maximize thermal performance and to create a lighter offering, 100% recycled PVC-U Thermal Inserts are inserted in every window at factory level consequently providing much higher efficiency than traditional steel bars with no compromise on installation quality!


Our ECOSlide window has been expertly evaluated to the highest standards in accordance with BS.6375 Part 1, and achieved remarkably impressive results under severe weather conditions as defined by BS.5368! Rest assured that your home is equipped with superior protection against inclement coastal weather so you can feel safe without sacrificing style.


With stricter regulations placed on ventilation, Optimus are able to provide a product that strikes the perfect balance of performance and visual appeal. A discreet design ensures compliance with Part F requirements whilst protecting traditional aesthetics for an unbeatable end result.
