Usage:

universal use (damp and wet environments, bathrooms and kitchens, facades, installation of windows and doors, floors)
base profiles for facade and window constructions
at windowsills, blinds and flush-mounted blind boxes
with sandwich panels
extremely suitable for the construction of low-energy and passive houses
dividing walls in damp and wet areas
kitchen worktops, boat equipment, bathroom furniture,
construction of cars (e.g. residential, commercial cars, ships, wagons, etc.),
as a climatic layer to prevent the formation and action of a thermal bridge in the detail of the supply of the perimeter wall to the concrete part of the foundation during the construction of low-energy and passive houses
exhibition stands, building structures, gates and doors, kitchens,

PURBLOCK 550 is available as large format boards, full profiles and profiles with PUR insert. We can make extra-standard sizes and shapes to order.
