Insulating a van ceiling hack | Van insulation

Installing celotex in a van conversion thanks to Greg Virgoe's videos I found these hangar pins that secure celotex to the roof of the van. Thanks to Greg for the insulation hack.
Go and check out Greg's videos, I wanted to share this video to help other van converters
