Frequently Asked Questions
Double glazing costs in the UK vary depending on the window size, frame material, and glazing specification. As a guide, a standard uPVC double-glazed casement window costs between 300 and 600 pounds installed. Timber double-glazed windows range from 800 to 1,500 pounds, and aluminium frames sit between 500 and 1,200 pounds per window. Sash windows are typically more expensive due to their complexity. Prices also vary by region, with London and the South East generally commanding higher installation costs. Always obtain at least three quotes from FENSA or CERTASS registered installers.
Both argon and krypton are inert gases used between the panes of double glazing to improve insulation. Argon is the most commonly used gas, offering good thermal performance at an affordable price point and improving insulation by approximately 30% compared to air-filled units. Krypton is a denser gas that provides superior insulation, approximately 40% better than air, but costs significantly more. Krypton is typically used in slimmer units where space between the panes is limited, such as heritage-style or slim-profile double glazing for period properties.
Key signs that your double glazing needs replacing include persistent condensation or misting between the glass panes, which indicates seal failure. Draughts around the window frame suggest deteriorating seals or warped frames. Difficulty opening or closing windows may indicate frame distortion. Visible damage such as cracks in the glass, discolouration of the frame, or rotting timber surrounds are clear indicators. If your windows are over 20 years old, they likely lack modern energy-efficient features like Low-E coatings and gas fills, meaning replacement could significantly reduce your heating bills.
Yes, double glazing significantly reduces noise from traffic and other external sources. Standard double glazing can reduce noise levels by 25 to 30 decibels, which is a noticeable improvement. For homes on busy roads, acoustic double glazing with laminated glass and varying pane thicknesses can achieve noise reductions of up to 40 decibels or more. The width of the air gap between panes also affects sound reduction, with wider gaps generally providing better acoustic insulation. Triple glazing offers further improvement for properties in particularly noisy locations across the UK.
Low-E (low emissivity) glass has a microscopically thin metallic oxide coating, typically applied to the inner surface of the outer pane in a double-glazed unit. This coating reflects long-wave infrared radiation (heat) back into the room while allowing short-wave solar energy and visible light to pass through. Low-E glass can reduce heat loss through the window by up to 50% compared to standard clear glass. In the UK, most modern double glazing units incorporate Low-E glass as standard to meet Building Regulations Part L energy efficiency requirements.
Triple glazing offers improved thermal insulation with U-values as low as 0.6 W/m2K compared to around 1.2 to 1.4 W/m2K for standard double glazing. However, triple glazing costs approximately 20% to 30% more than double glazing. For most UK homes, high-quality A-rated double glazing provides excellent performance and represents the best value for money. Triple glazing is most beneficial for north-facing elevations, properties in exposed locations, passive house builds, or homeowners seeking the absolute best thermal and acoustic performance regardless of cost.
Modern double glazing units from reputable manufacturers typically last 20 to 25 years, though many installations remain effective for 30 years or more. The sealed glass unit is usually the first component to fail, with the gas fill gradually leaking out over time and seals deteriorating. Frame lifespan varies by material: uPVC frames last 20 to 30 years, aluminium frames 40 to 50 years, and timber frames 60-plus years with proper maintenance. Regular inspection and maintenance of seals, drainage slots, and moving hardware can help extend the overall lifespan of your installation.
