FAQs
Thinking about upgrading your windows in Milton Keynes or Leighton Buzzard? Our expertly crafted casement windows are a popular choice for homeowners seeking style, security, and energy efficiency, but we know you might still have questions. We’ve addressed some of the most frequently asked questions to help you make an informed decision with complete confidence.
What are casement windows?
Casement windows are hinged on one side and open outward. They offer uninterrupted views, excellent ventilation, and a timeless aesthetic that suits modern and traditional homes.
Are casement windows energy efficient?
Yes, especially when crafted using premium profiles like the Deceuninck 2500 or 2800. These windows feature a robust thermal barrier designed to reduce heat loss, enhance insulation, and help lower your energy bills throughout the year.
Can I choose the colour and finish?
Absolutely. We offer over 30 colourways, including natural tones and woodgrain effects, all designed to complement your home. Each finish is durable, low-maintenance, and comes with a 10-year manufacturer’s guarantee.
How secure are casement windows?
Casement windows are some of the safest windows on the market. They feature multi-point locking systems, strong hinges, and robust frames. Moreover, they’re independently tested to meet modern security standards.
Are casement windows suitable for period homes?
Absolutely — especially when you choose a flush casement style or our 2800 Heritage Sculptured profile. These designs blend traditional charm with cutting-edge performance, making them the perfect choice for period homes and character properties. You’ll enjoy the classic look you love with all the comfort, efficiency, and security of modern uPVC.
How easy are they to look after?
Extremely easy. Our casement windows don’t need to be painted or varnished, just an occasional wipe down with soapy water to keep them looking immaculate.
Can I customise the glass or hardware?
Of course. Choose from a range of glazing styles, decorative glass options, and handle finishes to suit your space. You can even add traditional features like a dummy peg stay or choose from a butt hinge or mitred joint.
