Exterior Render

Pro.Tek offer a number of key systems for the refurbishment sector which are based on a range of modern insulation materials that include fire safe mineral fibre, lightweight expanded polystyrene, enhanced expanded polystyrene and high performance phenolic foam.

Our systems have been designed to enable various methods of fixing to be employed, dependant upon the substrate condition and type.

Rain Screens

A rainscreen is an exterior wall detail where the wall cladding stands off from the moisture-resistant surface of an air barrier applied to the sheeting to create a capillary break and to allow drainage and evaporation.

The rain screen is the wall cladding itself and prevents the wall air/moisture barrier on sheathing from getting wet.


Pro.Tek work with an extensive range of external cladding boards which allows you to choose and specify the right façade system at the right time for the right project.

Incredibly easy to work with, cost efficient and above all aesthetically attractive, the exterior of your building can be brought to life with our easy to shape and highly versatile broad range of products, available in an assortment of colours and designs to suit your creative needs.

Cavity Barriers

Cavity barriers work to improve a building’s safety by preventing the spread of fire within concealed voids. They provide essential protection whilst also helping to minimise air leakage and heat loss between the external cavity and the separating party wall.
