The best range of double glazing colours and styles
Double glazing windows have become essential additions to the home, improving insulation and reducing heat loss, thereby helping buildings become more energy efficient and much less draughty!
In addition to the reduced energy bills this can provide, homeowners also see the added bonuses of soundproofing (perfect for houses on a main road) and improved security.
With a big impact on your comfort while in your home, as well as on a house’s resale value, double glazing is an important investment – so why settle for something that doesn’t match the rest of your exterior? At Roofline Design, we offer a huge range of window styles, so you can be sure you’ll find the right fit.

Glazing bars and opening styles
Our windows are purpose-built to order, meaning we can provide double glazing casement windows in a variety of opening styles, whether they are top-hung, left-hung, right-hung, or a combination of the three.
In addition, we can also install sliding windows, as well as tilt and turn windows. Just contact us for more information, or a no-obligation quote.
For the finishing touches, we also install glazing bars for double glazing windows in both grid and diamond patterns, allowing you to achieve a range of striking effects.
Installation
Your new windows will be installed by our trained and accredited team, who will visit your home, carry out all of the work, tidy up after themselves, and remove all rubbish from your property, all of which is included in the price.

Great work and overcame scaffold challenges
“Great service from a fair quote, booking, date confirmed and everything on time. Finished to a high standard.”

“We had our guttering fully redone and could not fault them a single step of the way. Professional and friendly, great communication throughout and completed the job quickly. Keith and Andrew, who installed everything, were brilliant and answered any questions that we had. We would definitely recommend them to others and will use them again if we need to in the future!”

Fascia, soffits, dry verge and guttering
