Technical Drawing

Insulation washer to be used with various types of screws to prevent thermal bridging.

Both Polycaprolactam (commonly referred to as “Nylon 6”) and Polypropylene are polymers which are stable under exposure to low levels of ionising radiation (Ultraviolet, X-Ray, etc). They are also stable under exposure to certain aggressive chemicals. Products have radial holes and other head surface features to allow render to “key” (mechanically adhere) to the washers.

Evolution Insulation Washers are used in conjunction with various screw types to secure rigid PIR (Polyisocyanurate) and PUR (Polyurethane) insulation panels/ boards to various substrates (commonly timber, steel and masonry). All washers have a recessed mounting point for the screw heads: this ensures that the screw head is below the surface of the washer and aids in reducing cold-bridging
