Easy way to build secure insulated pillow for ISEC

Securing fiberglass is one off the challenge in my ISECs building.

to secure food from fiber glass contamination I used plastic. But as plastic sheet can’t go in the contact with high temperature, I sewed it with cotton fabric and then cover all with heat protection material( Teflon).
By doing so, the safety of food is ensured. I used an uphosterer to achieve to sew sheets. It increases the ISEC building cost but in other hand it makes ISEC construction standardised and fast.

Pillows can be handle together with clasps.

Finally, we get well insulated ISEC.
