Casement Windows –
The Popular Choice
uPVC casement windows are a popular choice in the UK, and make up a large proportion of windows within residential properties. These windows incorporate a mixture of fixed panes, transoms (horizontal), mullions (vertical) and opening vents (side or top), combining both design and ventilation to suit.
Our uPVC casement windows are one of the most secure window styles on the market. The majority of the hardware is protected, due to being concealed within the window frame, acting as a deterrent to any ‘would-be’ intruders. Our windows can be manufactured to meet the specifications required to be backed by the police initiative ‘Secured by Design’ – created to raise standards and help avoid criminality. Aesthetics are also enhanced due to the hardware being neatly obscured.




Energy Efficient uPVC Windows in Plymouth
uPVC casement windows are one of the most energy-efficient styles available, due to their innovative design. Strong seals on each side of the uPVC profile, help the vent to press against the frame in a secure way. Therefore, as a result of the seals being tightened, the windows are airtight – minimising the risk of cold air coming in, or hot air from escaping.
Cost-effective uPVC windows provide efficient thermal insulation, so the internal structure of the profile traps heat inside your home, meaning you can keep your family warm, whilst also reducing your energy bills. The benefits of opening vents are that you can still ventilate your home or business whenever necessary. These vents can also be locked in a position where only a small gap is visible – allowing for continuous circulation for the security conscious – ideal for ground floors.
