Granada’s unique system is purpose-built to address the common issues of older or single-glazed windows, ensuring your home is quiet, warm, and secure.

🤫1. Unrivalled Noise Reduction (Quiet)

Secondary glazing offers the most effective sound insulation on today’s market, significantly outperforming all other glass solutions.

• Our bespoke units are tightly sealed to reduce noise levels by up to a whopping 80%.
• It is scientifically proven to reduce noise by up to 54 decibels.
• Ideal for homes near busy roads, flightpaths, or city centres where external noise is a persistent issue.

🌡️ 2. Superior Thermal Insulation (Warm)

If draughty windows are a concern, secondary glazing adds an extra layer of defence against heat loss.

• The gap between your existing and secondary unit creates an insulating air layer that can reduce heat loss by up to 65%.
• This improvement in thermal insulation means you can save up to 10% more energy than you would with traditional double glazing.
• Protect your home against heat loss and radically reduce your heating costs.

🔒 3. Enhanced Security (Secure)

Secondary glazing provides a unique, additional physical barrier and deterrent to any would-be intruders.

• The durable, high-quality aluminium frames are securely fixed to resist forcing.
• The system creates a further layer of defence, making the window incredibly difficult to open from the outside.
