Common questions about Extreme UPVC windows
Choosing new windows is a big decision, so itโs normal to want clear answers before you commit. Below are some of the most common questions MPN customers ask about Extreme UPVC Windows – covering energy efficiency, security, maintenance, guarantees and the installation process – so you can feel confident about the right choice for your South Wales home.
1) Are Extreme UPVC Windows energy efficient?
Yes. Extreme UPVC Windows use insulated multi-chamber frames and high-performance glazing options to help reduce heat loss and draughts. That can keep your home warmer in winter and more comfortable year-round. Weโll recommend the right specification for your property, budget and energy saving goals.
2) How secure are Extreme UPVC Windows?
Extreme UPVC Windows are built with security in mind. Depending on the specification, youโll benefit from multi-point locking, reinforced hardware, strong hinge protection and durable handles. When correctly fitted, these features help defend against common forced entry methods and improve peace of mind at home.
3) What window styles are available in the Extreme UPVC range?
MPN offers a wide choice, including Casement, Sliding Sash, Tilt & Turn, Bay & Bow, Fixed, French, Cottage, Shaped & Gable and Reversible styles. This makes it easy to match a period property, modernise a faรงade, or keep a consistent look across extensions and older rooms.
4) What colours and finishes can I choose for Extreme UPVC Windows?
Youโre not limited to plain white. Extreme UPVC Windows are available in a variety of colours and woodgrain – effect finishes to suit traditional and contemporary homes. We can guide you through popular options, show real examples, and help you choose a finish that complements your doors, brickwork and interior.
5) Are Extreme UPVC Windows low maintenance?
Yes. UPVC is designed to stay looking great with minimal effort. You wonโt need to paint or treat the frames; a quick clean with mild soapy water is usually enough. Weโll also advise on simple checks for hinges, seals and handles to keep everything running smoothly.
6) Do Extreme UPVC Windows help reduce outside noise?
Yes they can. Better sealing and modern glazing options help reduce draughts and lower the amount of noise that travels into your home. If you live near busy roads or schools, we can recommend a specification designed for improved acoustic performance, tailored to your property.
7) How long does it take to fit Extreme UPVC Windows?
Installation time depends on the number of windows and the complexity of the job. Many homes are completed within a few days. Weโll confirm timelines in advance, explain what to expect on fitting days, and keep disruption to a minimum while maintaining a high standard of finish.
8) What guarantee comes with MPN Extreme UPVC Windows?
MPN provides long-term 20 year guarantee for added reassurance. Your Extreme UPVC Windows come with a written guarantee, plus the relevant certification and installation protection.
