Why WASHERS matter?

Because washers are small and relatively inexpensive, their importance in a

roofing project is sometimes overlooked. But poor quality washers can result in
enormous cost if it is badly designed and made of inferior material. Here’s why:

• The washer is vital in maintaining the integrity of the roofing
system.
• There are four vital components to a good washer - design,
material, conductivity and traceability.
• Design - Early breakdown of the washers will result in, at best,
the replacement of all fasteners and seals across the entire roof,
and at worst, considerable water damage to the building.
• Material - The secret of the DEKS washer is its premium EPDM
(Ethylene Propylene Diene Monomer) blended with UV and Ozone
stabilizers, curatives and processing oils. The blend is critical to
sealing, UV resistance, life span and conductivity.
• Conductivity – according to the Senior Principal Research
Engineer, BHP RESEARCH -“We have found that DEKS black EPDM
washers exhibit exceptional levels of performance and provide
complete compatibility with BHP Colour board and Zincalume
coated steels. A controlled level of carbon in this product
provides superior mechanical properties and superior overall
durability.”
• Traceability - DEKS premium range of washers are always marked
with the DEKS name or a registered feature such as the blue line.
