## Questions & Answers

**Q: This might be weird but can u sew it and it hold the stitching well?**
A: I sewed mine to curtains for my skoolie and it worked great the thread wanted to slip through foam so I had to make a few extra knots on end but overall worked well

**Q: how thick is it?**
A: Foam is 3mm thick.

**Q: How much does it weigh compared to traditional reflectix?**
A: It is probably half the weight.  It is very effective, very light, thinner than the bubble types, and can be used in many ways.  I use it as windshield covers, either inside or outside, for our car and I even use it for a very effective insole and canting shim for my ski and snowboarding boots.

**Q: Would this insulation work on the bottom inside of a greenhouse window?**
A: It reflects the sun away , it's very very thin . If that is what you are trying to do is reflects the sun out then it may work
