## Questions & Answers

**Q: can the weatherseal go between the bottom of the air conditioner and the window sill?)**
A: If there is space then yes. It’s a foam so you can manipulate it into the smallest crevices.

**Q: does it absorb moisture?**
A: Never had to experience moisture

**Q: What is the maximum temperature rating of this foam?**
A: Sorry, no idea. I use it for insulation. It does not come with temperature ratings listed,  but as it's very light, thick sponge rubber I wouldn't think it would withstand very high heat.

**Q: Is it washable?**
A: It can be hand-washed in mild soapy water' rinsed and air-dried as long as the foam has not gotten crumbly with age.
