Insulating or Thermal Fabric for Sewing: What Is It and What Can You Use It For?

It already smells like spring, and we're dreaming of countryside getaways, walks on the beach, weekend picnics, mountain hikes… Although the material we're introducing today will also be very useful in your day-to-day life. For example, if you're someone who takes lunch to work. […]

It already smells like spring, and we're dreaming of countryside getaways, walks on the beach, weekend picnics, mountain hikes… Although the material we're introducing today will also be very useful in your day-to-day life. For example, if you're someone who takes lunch to work. Insulating fabric for sewing is simply that silver-colored fabric you can find inside thermal bags. Does that sound familiar?

I'm sure you have one of these thermal bags at home, but interestingly, they're all hideous. With garish, outdated colors or the typical one featuring a yogurt or soft-drink brand. It keeps food at the right temperature, whether cold or hot. It's also useful for carrying medicines or injections that need to be stored in the refrigerator and kept cold so they don't lose their effectiveness.

Use insulating fabric to make the lining for a pretty bag, like the one we made in last Friday's tutorial, and that's it.

Although it obviously doesn't have the same texture and consistency as regular fabric, it's very easy to sew. In fact, you don't need to use a special needle or presser foot. What we do recommend is that, when securing the fabric before running it through the machine, you don't use pins. It's better to secure it with clips or water-soluble glue so you don't puncture it.

 

Suggestion for using insulating fabric

The tutorial we mentioned earlier. To keep the temperature steady, we made this bag with a roll-top opening. That way, you can roll it several times, providing better insulation for the inside. The closure is Velcro, so you can adjust it according to how full it is and keep it perfectly closed at all times.

The design is crossbody-style, so it's easy and comfortable to carry. But if you prefer, you could also add backpack-style straps or just one handle at the top, like a briefcase. It's up to you!

Here's the link to the thermal bag tutorial.
