Damage that penetrates the vacuum insulation panel can cause the vacuum to be lost, reducing its thermal performance.
For this reason, vacuum insulation panels should not be drilled, nailed or sawn.
Gradient specifically states that drilling, nailing or sawing a Vacuum Insulation Panel can cause loss of vacuum and reduce thermal performance. Deck-VQ® incorporates protective high-density PIR layers designed to provide additional protection to the vacuum panel during installation and use.
Installers should follow the manufacturer's installation instructions and avoid activities that could damage the panels.
