Firstly, it’s essential to ensure that your windows are completely closed. Oftentimes, we’ve encountered situations where windows aren’t fully shut due to misaligned latches or accumulated dirt in the window channels. If the window handles are turned incorrectly, they may catch on the upper sash’s frame, preventing the lower sash from fully descending. Therefore, cleaning out any dirt buildup before closing the window properly is advisable.
Consider installing soundproof inserts if outside noise persists even with fully closed windows.
Why choose inserts over window replacement windows?
Replacement windows typically have low sound ratings, known as Sound Transmission Class (STC) ratings. Even premium triple-pane windows usually have an STC rating of around 32, while double-pane windows rate between 28-30, both falling short of the minimum STC 40 required for effective soundproofing. In contrast, soundproof inserts offer a cost-effective solution with an STC rating of 48 when paired with double-pane windows, making a noticeable difference in noise reduction.
What exactly are soundproof inserts?
These are solid window treatments made of clear glass, fitted inside your window opening between the existing windows and your window coverings like blinds or curtains. They create an air gap that traps sound waves, significantly reducing noise infiltration without blocking natural light. Moreover, they maintain the exterior aesthetics of your property and comply with homeowners’ association regulations. Custom-made to fit your windows precisely, they prevent noise from leaking around the edges and can be installed in a single day without major construction work.
How do Soundproof Window Inserts Work?
The functioning of soundproof window inserts is based on the sound-absorbing capabilities of laminated glass, the air gap created between the insert and the existing window when installed, and the tight seal around the edges of the insert. The air gap acts as a buffer zone for sound waves. This setup absorbs, reflects, and cancels out noise, resulting in a quieter indoor environment. Additionally, the insert reduces energy loss by up to 60% per window, enhancing energy efficiency.
Sealing is crucial for soundproof inserts to prevent sound from seeping through gaps. Our inserts boast an infiltration rate of less than .01 cubic feet per minute per lineal foot, surpassing international energy conservation standards. Notably, alternatives like “soundproof” drapes or curtains lack this sealing mechanism, allowing sound to pass around the edges unhindered.
Insert Pricing & Installation
When it comes to pricing and installation, costs vary depending on factors such as the number, size, and configuration of inserts required. We offer comprehensive services covering measurement and installation, as precise fitting is vital for effective soundproofing. Typically, installation is completed within five to seven weeks after receiving a 50% down payment, with residential projects typically taking one to two days.
Benefits
- Stop unwanted noise from traffic, construction, outdoor equipment, and more.
- Protect against energy loss, both cold and heat.
- Reduce the ultraviolet light that fades carpets and furniture.
- Minimize window condensation.
- Decrease drafts and allergens.
Available Configurations
- Single-piece insert: This removable panel is our most popular soundproofing window insert. It’s the least expensive and most effective because it has the least number of places to contribute sound leakage. To open your window, you remove it by pulling to release the magnetic frame from the steel frame. It’s the best choice if you don’t open your windows daily.
- Operating insert: This soundproof window insert functions like a regular sliding window. The lower sash slides up and down or side to side, whichever way your old windows move. This insert is the best choice if you regularly open your windows in the room. However, this is the most expensive option due to the higher cost of manufacturing.
- Two-piece insert: This configuration consists of upper and lower panels. providing easier access to existing window locks while minimizing costs.
