Frequently Asked Questions
Browse our FAQs below to find answers to commonly asked questions or get in touch!
01205 311144What is double glazing?
Double glazing refers to a window construction that involves two panes of glass separated by a space, usually filled with argon gas. This design enhances thermal efficiency, reduces noise, and improves security compared to single-glazed windows.
How does double glazing improve energy efficiency?
Double glazing creates an insulating barrier that helps maintain the temperature within your home. It reduces heat loss in winter and keeps your home cooler in summer, resulting in lower energy bills and a reduced carbon footprint.
Is double glazing worth the investment?
Yes, while the initial cost may be higher than single glazing, the long-term savings on energy bills, increased comfort, enhanced security, and potential increases in property value make double glazing a worthwhile investment.
Can I get double glazing in different styles and colours?
Absolutely! At Boston Trade Frames, we offer a wide range of styles, including casement, flush sash, sliding sash, and tilt-and-turn windows, all available in various colours and finishes to match the aesthetics of your home.
How long does installation take?
The installation time for double glazing can vary depending on the number and type of windows being fitted. However, our professional team strives to complete the installation efficiently, typically within a day or two for most projects.
Will double glazing reduce noise from outside?
Yes, one of the significant benefits of double glazing is its ability to reduce external noise. Our windows can offer sound insulation that significantly lowers your home's exposure to traffic, chatter, and other disturbances.
Are your products guaranteed?
Yes, all our double-glazing products come with comprehensive guarantees. We stand by the quality of our materials and workmanship, ensuring our customers receive reliable products that last for years.
