[Warm Window] Simple Inner Window DIY Kit｜Order Glass.com

An inner window is a window remodeling project in which another new window is installed inside an existing window.

By installing an inner window, heat transfer can be reduced, creating a room that is warmer in winter and cooler in summer.

While most inner windows are generally installed by window specialists or remodeling companies, our [Warm Window] Simple Inner Window DIY Kit allows even DIY beginners to easily install an inner window, as the components are simply attached with double-sided tape.

For this reason, our [Warm Window] Simple Inner Window DIY Kit has been adopted by many people who want to install inner windows on their own without spending a lot of money.

While glass is used for ordinary inner windows, the [Warm Window] Simple Inner Window DIY Kit uses a material called "hollow polycarbonate.

Hollow polycarbonate is made by overlapping two sheets of polycarbonate, and its cross-section has a structure similar to corrugated cardboard.

Because there is an air layer in between, it is not only lighter and easier to handle than glass, but also keeps the interior warm (or cool) by reducing heat transfer.

Many DIY sets of inner windows from other companies sell rails and hollow polycarbonate in fixed sizes, which require you to cut them yourself using a saw or similar tool.

We cut the products to the exact size of the customer

By installing the [Warm Window] Simple Inner Window DIY Kit, a layer of air is created between the window and the window, reducing heat transfer.

This makes it difficult for warm air inside to escape in winter and hot air outside to enter in summer.

This also makes it easier for air conditioners and heaters to work, leading to savings on electricity bills.

Warm Window] Simple Inner Window DIY Kit has the same high performance of keeping a room warm (thermal insulation performance) as general glass inner windows.

A comparison of "thermal transmittance," which expresses the ease of heat transfer, shows that the values are not significantly different between ordinary glass inner windows and the [Warm Window] Simple Inner Window DIY Kit.

*According to our own research. Outer window glass: float glass 3 mm thick / inner window glass (for glass inner window): pair glass 12 mm thick / inner window glass (for [warm window] simple inner window DIY kit): hollow polycarbonate 4 mm thick

Not only is it easy to install, but the low installation cost and high savings are other features of the [Warm Window] Simple Inner Window DIY Kit.

For a window 102.9 cm high and 200 cm wide, the [Warm Window] Simple Inner Window DIY Kit costs about 17,000 yen, less than half the price of a standard inner glass window.

The electricity savings are greater than the cost of installing a simple inner window DIY kit, so the savings can be realized more quickly than with a standard inner glass window. *
