Soundproof Windows: How to Make Your Home Quieter

Most outside noise comes in through gaps and thin glass. Sealed uPVC frames with laminated or double glass reduce traffic noise a lot. No window removes all sound, but the difference is easy to hear.

Where the noise gets in

• Gaps around the window and between sashes.
• Thin single glass that vibrates with sound.
• Old frames that no longer close tightly.

What helps the most

• Sealed uPVC frames with gaskets on every side.
• Casement windows, which press shut on their gaskets.
• Laminated glass: a sound-damping layer between two sheets.
• Double glass (DGU) with an air gap.
• Proper installation: the gap between frame and wall sealed with foam and silicone.

What to expect

On a busy road, the change from old windows to sealed uPVC with laminated glass is very noticeable, especially in bedrooms. Very low sounds such as heavy trucks are the hardest to block.
