Glazing has a big impact on comfort, energy efficiency and noise levels. VELUX offers different glazing types to suit bedrooms, lofts, bathrooms and extensions. This guide explains the main options in plain language so you can choose with confidence.
Standard Energy-Efficient Glazing (e.g. 2070)
Many popular VELUX roof windows are supplied with high-performance double glazing such as 2070, which offers:
Good thermal insulation (low U-value).
Safety glass on the inside pane.
Enhanced noise reduction compared with older units.
Durable, low-maintenance performance.
Noise Reduction & Enhanced Glazing Options
For homes near busy roads, railways or flight paths, specialist glazing can improve acoustic comfort. Options may include:
Extra noise reduction layers.
Improved sound insulation for external noise.
Better performance in wind and rain.
These glazing types are ideal for bedrooms and home offices where a quieter environment is important.
Solar Control & Sun Protection Glazing
In very sunny rooms or south-facing roofs, solar control glazing helps reduce overheating:
Limits the amount of solar gain in summer.
Helps keep rooms more comfortable in hot weather.
Still allows plenty of natural light.
For even more heat protection, consider combining solar control glazing with external awnings or shutters. See our VELUX Blinds & Shading Guide.
Triple Glazing & Low-Energy Homes
Triple glazing is often chosen for low-energy or highly insulated homes where maximum thermal performance is required.
Very low U-values.
Improved comfort in cold climates or exposed locations.
May be specified as part of energy-efficient building standards.
Glazing for Bathrooms & High-Humidity Rooms
In bathrooms and kitchens, both glazing and ventilation are important:
Choose safety glazing and good ventilation options.
Use the ventilation flap regularly to reduce moisture build-up.
Consider blinds and materials suited to humid spaces.
