How long do double glazed windows last? +
Well-made UPVC double glazed windows typically last 20 to 25 years before the sealed units start to fail or the frames become brittle. Aluminium frames can last 30 to 40 years, and timber frames last indefinitely with proper maintenance. Signs your windows need replacing include misting between panes, draughts around the frame, difficulty opening or closing, and visible frame damage.
What is the difference between UPVC, aluminium and timber windows? +
UPVC is the most popular and affordable option — low maintenance, good insulation, and widely available. Aluminium frames are slimmer, stronger, and suit modern designs, but cost 40-60% more than UPVC. Timber frames offer a traditional look and excellent insulation but require regular painting or staining every 3 to 5 years. Each material has its strengths depending on your property style and budget.
Is triple glazing worth the extra cost? +
Triple glazing costs around 30-50% more than double glazing and provides a modest improvement in thermal performance — typically reducing heat loss by a further 20-30%. For most UK homes, A-rated double glazing is the best value option. Triple glazing makes most sense if you live in an exposed or particularly noisy location, or if you are building a passive house to very high energy standards.
Are there window fitters in Armagh who do free surveys? +
Most reputable window fitters in Armagh offer free, no-obligation home surveys and quotes. During the survey, the fitter will measure your windows, discuss frame materials and glass options, and provide a written quotation. Be wary of high-pressure salespeople who want you to sign on the spot — a trustworthy fitter will give you time to compare quotes.
Will new windows reduce noise from outside? +
Yes, replacing old single glazing or failed double glazing with modern sealed units will noticeably reduce outside noise. Standard double glazing reduces noise by around 25-30 decibels. For maximum noise reduction, ask about acoustic glass or unequal pane thickness (e.g. 6mm outer, 4mm inner) which disrupts sound vibrations more effectively. Triple glazing also offers improved sound insulation.
How long does it take to replace a window in Armagh? +
A single window replacement typically takes 1 to 2 hours from start to finish. A full house of windows in Armagh usually takes 1 to 2 days depending on the number of openings and any complications like rotten lintels or damp. Your fitter should leave each opening weathertight before moving on to the next.
