Have Questions About Our Windows, Doors & Conservatories?
Choosing the right windows, doors, and conservatories for your home is an important decision. We’ve answered some of the most common questions to help you understand our products, installation process, and what to expect. If you need more details, our team is always happy to help.
Can't see the answer you're looking for?
Contact UsAre uPVC windows more durable than traditional wooden or metal frames?
Yes! Unlike wood or metal frames which are prone to rotting, rusting or warping over time, our high-quality uPVC frames are designed to withstand harsh weather conditions without losing their structural integrity.
Do I need triple-glazed windows for better insulation?
While double glazed windows already provide excellent thermal efficiency by trapping heat inside during winter months and keeping cool air in during summer heatwaves, opting for triple glazing further enhances energy savings as well as noise reduction benefits.
How secure are uPVC windows?
Our uPVC window installations come with multi-point locking mechanisms which ensure enhanced security features compared to standard single locks found on other types of replacement products, giving homeowners peace mind knowing they're protected against potential break-ins.
Can I choose custom colours for my new uPVC casement windows?
Absolutely! At Crown we understand the importance of aesthetic appeal when it comes making any property stand out. That's why we offer a vast selection of stunning colour choices.
