Large soundproof windows, which measure approximately 44 by 52 inches, involve the highest material and labor costs. Due to their substantial size, they necessitate the most resources for a flawless installation. While large windows provide optimal noise reduction and can dramatically enhance views, they also come with a higher price tag, around $600 – $1,800 per unit. 

Here is how much soundproof windows by size: 

Soundproof Windows Cost by Glass Type

The cost of windows with noise reduction features typically ranges from $350 to over $1,000 for the glass panes alone. The cost variability varies based on the type of soundproof glass used. It's worth noting that there are four main types of soundproof panes available in the market - double pane, triple pane, acoustic glass, and laminated glass. Each of these options has its unique attributes, effectiveness, and associated costs and value. Let us have a close look at each type of soundproofing window pane:

Soundproof Windows with Double Panes

Double-pane windows, an effective soundproofing solution, are designed with two layers of glass separated by a spacer that houses an inert gas, commonly argon, xenon, or krypton. The gas-filled space enhances thermal insulation while also significantly reducing noise penetration. The cost range for windows with double panes generally falls between $300 and $2,100 per unit, including installation. 

Soundproof Windows with Triple Panes

Triple-pane windows, offering an advanced level of soundproofing, take it a step further with three layers of glass separated by a spacer. Each space between the panes is filled with an inert gas. The extra layer of glass and the associated gas-filled spaces provide superior thermal insulation as well as enhanced noise reduction. The costs for these windows, including materials and labor, typically range from $550 to $3,540 per unit.

Soundproof Windows with Acoustic Glass

Acoustic glass windows offer an optimal solution for reducing external noise. They are designed with two or more layers of laminated glass for improved sound insulation. Besides blocking noise, they also provide safety benefits, as their laminated nature makes them harder to break. The price for these acoustic glass windows usually falls within the range of $350 to $650.

Soundproof Windows with Laminated Glass

Laminated windows are the most effective soundproof means, made of either two or three sheets of float or tempered glass, with a layer of plastic sandwiched in between them. The plastic interlayer boosts the window's ability to absorb noise, providing considerable sound absorption(up to 95%). The cost of these noise-reduction windows begins at around $950 for a double-pane window and goes above $1,000 for a triple-pane window. Some extra-sized units may cost over $1,600, including installation.

Soundproof Windows Cost by Frame Material

You can also enhance the energy efficiency and soundproofing characteristics of the window by replacing its frame. Depending on the selected material, the cost of the new pane will vary from $150 to $500. The prevent materials used in soundproofing windows are vinyl, wood, and aluminum. Below, we will delve deeper into understanding the specifics of each material, aiding your decision-making process for choosing the frame material best suited to your needs and budget.

Soundproof Windows with Wood Frames

Wood-framed soundproof windows, costing between $100 and $350, offer a host of benefits, such as weather resistance, energy efficiency, and an eco-friendly nature. These factors contribute to a potential higher return on investment over time. However, it's worth noting that they come with higher labor costs for installation and may require more maintenance than their aluminum and vinyl counterparts.

Soundproof Windows with Aluminum Frames

Aluminum-framed soundproof windows, with a price range of $150 to $350, are known for their durability and resistance to weather conditions. They also require low maintenance, making them a hassle-free choice for homeowners. However, these frames are less energy-efficient compared to others and can be susceptible to dents, which is something to consider before making a decision.

Soundproof Windows with Vinyl Frames

Vinyl-framed soundproof windows, with costs falling between $150 and $500, are appreciated for their cost-effectiveness, notably lower installation labor costs and low maintenance requirements. However, these frames might not be the best choice if durability and longevity are high on your priority list, considering their relatively short lifespan of 10 to 20 years. Therefore, while vinyl frames may offer initial cost savings, it's essential to weigh these benefits against their durability limitations.
