Product Data Sheet va-Q-patch DESCRIPTION va-Q-patch is a thermal insulation system consisting of a vacuum insulation panel (VIP) covered on both sides with a full surface polyethylene (PE) foam lamination. It is primarily used as a high-performance insulation layer for heat storage tanks to increase their energy efficiency to a label rating of A and A+ according to the EU regulation 812/2013. The standard configuration includes a thin and adhesive PE foam lamination on the tank side to protect the VIP against welding defects and metal shavings amongst other impacts and to ensure a perfect connection to the tank. va-Q-patch is delivered in a space-saving, flat state and can then be bent around the tank at the installation site. It can be used as an additional layer such as beneath an ordinary polyester fleece insulation. Version: 1.1 Author: Alexander Göbel
