Soundproofing Windows: Simple Guide for a Quieter Home

Having noisy neighbors or living near a busy road can make your home life stressful. The sounds of traffic, construction, loud music, and more can disrupt your sleep, concentration, and relaxation at home. Fortunately, there are ways to reduce noise coming through your windows. With some simple upgrades and DIY soundproofing techniques, you can make a noticeable difference in the noise levels inside your home.

Check Your Windows for Gaps and Cracks

Before making any major changes, inspect your windows for potential air leaks that allow sound to travel through. Feel around the window frames and sashes for gaps where air is coming in. Also look closely at the seals around the edges of the window panes – over time, seals can wear out or become brittle and loose. Replacing worn seals and using caulk to fill any cracks or gaps can immediately improve the sound insulation of your windows.

Install Heavy Curtains or Soundproof Blinds

One of the easiest ways to soundproof existing windows is by adding window coverings. Heavy curtains made from dense fabrics like velvet, quilted blankets, or blackout cloth can absorb and block sound. For best results, use curtain rods that extend well past the window edges to completely cover the window when closed. Soundproof blinds are another option – look for layered blinds designed specifically for noise reduction. The mass of the blinds blocks more sound waves. Keep blinds fully closed to maximize sound absorption.

Upgrade Your Windows

If your existing windows are single pane, switching to newer double pane or even triple pane windows can make a significant difference in soundproofing. Multi-pane windows have extra air space between panes that dampens noise. For optimal noise reduction, choose panes made from laminated or tempered glass – they are thicker and help block more sound frequencies. Also make sure that replacement windows have a high STC (Sound Transmission Class) rating from the manufacturer, and use materials like rubber, foam, or metal around the edges to reduce vibration. Installing new high-quality, airtight windows can be a pricey upgrade but also very effective at reducing noise over the long-term.

Add Interior or Exterior Storm Windows

Installing extra storm windows is an affordable way to improve both insulation and soundproofing. Interior storm windows mount on the inside of your existing windows. Exterior storm windows attach on the outside. Both create an additional barrier and airspace to reduce noise infiltration. For soundproofing, opt for well-sealed triple track storm windows. Prioritize installing storm windows in bedrooms or other quiet areas.

DIY Soundproofing Solutions

For a budget-friendly option, there are many DIY techniques you can use to soundproof windows. Placing a heavy blanket or quilt over the window pane and securing it around the edges helps absorb sound. Mass loaded vinyl applied to window frames is effective at blocking noise. Foam weatherstripping placed on windows seals air gaps that let in sound. With these simple DIY soundproofing solutions, you can see noticeable noise reduction without expensive upgrades.


Is weatherstripping an effective way to soundproof windows?

Weatherstripping is indeed effective for soundproofing. It involves applying strips of material around your window frames to seal gaps and prevent noise infiltration. It’s a cost-effective way to enhance window insulation and reduce noise.

Can acoustic curtains or blinds effectively reduce noise?

Acoustic curtains and blinds are designed with specialized sound-absorbing materials that help dampen noise. When hung over your windows, they absorb and reduce the transmission of sound, making your living space quieter.

What is double-glazing, and how does it reduce noise effectively?

Double-glazing is a process where two layers of glass are installed with a space in between. This space acts as an additional barrier to sound, preventing noise from easily passing through. Double-glazing is highly effective in reducing noise infiltration.

Can you retrofit your existing windows with double-glazing?

Yes, you can retrofit your existing windows with double-glazing. This involves adding a second layer of glass to your current window frame with a gap in between. It’s a more involved process but can significantly improve noise reduction.

What are acoustic window films, and how do they reduce noise?

Acoustic window films are thin layers applied to your window glass. They add mass to the window, which helps dampen vibrations and reduce noise transmission. These films are an effective way to minimize noise infiltration.

Are there any DIY soundproofing solutions for windows, and how effective are they?

Yes, there are several DIY solutions for soundproofing windows, such as adding heavy curtains, installing weatherstripping, or using draft stoppers. Their effectiveness varies, but they can provide noticeable improvements in noise reduction.

How much should you budget for soundproofing your windows?

The cost of soundproofing windows can vary widely depending on the chosen method and the size of your windows. It can range from a few dollars for DIY solutions to hundreds or even thousands of dollars for professional installations.

Is it advisable to attempt window soundproofing yourself, or should you hire a professional?

Whether you should DIY or hire a professional depends on your skills and the complexity of the project. Simple solutions like adding curtains or weatherstripping can be DIY, but more extensive upgrades may require professional expertise.

Will soundproofing your windows also improve energy efficiency?

Yes, some soundproofing methods, such as double-glazing and window films, can also enhance energy efficiency by reducing heat loss and minimizing drafts, making your home more comfortable and energy-efficient.


Soundproofing existing windows takes some effort but can greatly improve your home’s ambiance. Using heavy window coverings, sealing cracks, upgrading window panes, and trying DIY options are all effective ways to reduce noise coming through your windows.
