What are interior window inserts and why do I need them?

Did you know that your windows will get less efficient at keeping air and noise out of your home as they get older? It’s a natural part of aging with your home as the wood and framing settle. The seals around your windows get older and don’t work as well. This is where you’ll benefit from interior window inserts. At Windows Interior, we can help you find the best window inserts for your home to help solve this problem. If you’ve never considered inserts, keep reading this short guide where we’ll explain what they are and why you need them.

What are interior window inserts?

Interior window inserts are a supplementary piece of plastic that’s lined with silicon to create a secondary seal around your window sill. They function like storm windows and provide a number of additional benefits for your home. They’re far more affordable than replacing your windows and don’t take away any of the views that you enjoy every day.

Why do I need interior window inserts?

Depending on the type of interior window inserts you buy, you can enjoy different benefits. From noise reduction to reducing UV rays entering your home to energy efficiency. We have solutions for each so you can customize your windows.

Reduce outside noise

You can keep outside noise where it belongs by installing Acoustic Indow inserts. These inserts are effective at reducing outside noise by a considerable amount. If you have single-pane windows, you already know that noise from outside comes into your home pretty easily. Window inserts create an extra barrier to reduce sound coming into your home by as much as 70%.

Improve energy efficiency

In addition to keeping sound from coming out, your interior window inserts will help prevent conditioned air from escaping. The positive pressure in your home that’s created by your HVAC system makes the air want to naturally escape your home through any available crevice. With the tight seal created by your window interiors, you’ll notice that your heating and cooling bills will drop as you’re better able to maintain a temperature in your home.

Reduce intense natural light and solar heat

If your living room or kitchen faces west, you’ve probably experienced the blinding light and intense heat of a sunset, especially during the summer. You can lightly tint your windows by installing Shade Grade inserts. These window inserts are effective at reducing the amount of intense sunlight and solar heat entering your home in the evening. Even the minor tinting of these inserts will go a long way to keeping your home cooler during the summer.

Reduce UV ray penetration

Excessive exposure to UV rays from the sun is not only dangerous for our skin but it’s harmful to the items in your home. UV rays will dry out and damage your flooring, furniture, and upholstery. By installing Museum Grade inserts you can filter up to 98% of UV rays from getting into your home and protect your family and your belongings.
