best for: roof areas with less foot traffic and transitions to exterior wall joint covers, where seismic or multi-directional movement must be accommodated.

Introducing the R2001

The PROROOF Series R-2001 & RK-2001 is an innovative roof expansion joint cover system crafted for roof areas where seismic and multi-directional movement is essential. This system integrates a full aluminum profile, designed specifically for roofs, ensuring watertight integrity while accommodating movement.

seismic movement accommodation

the proroof series effectively manages seismic shifts and thermal expansion, allowing the roof structure to move without compromising the joint’s functionality. this multi-directional capability makes it ideal for areas prone to temperature fluctuations and seismic activity.

water protection

rain runs off the sloped aluminum cover plate of the proroof r2001. where required, a tpe/epdm water barrier is fitted beneath the cover, held in the aluminum base frames on both sides, as a second line of protection for the roof below.

Seamless Water-Barrier Integration

This allows floor waterproofing to seamlessly merge with a continuous water barrier, ensuring a 100% watertight membrane. Designed for ultimate reliability, it eliminates leakage risks, delivering unmatched protection and durability for expansion joint systems.

Optional Vapor Barrier

For added protection, an optional vapor barrier is available, constructed from either EPDM or TPV, which offers high tensile and tear resistance, ensuring long-term performance against moisture penetration.
Optional Vapor Barrier

Galvanized Steel Turnbar

A corrosion-resistant galvanized steel turnbar with an “A” coating provides centering and support, ensuring that the cover plate remains aligned during movement, thus extending the life of the system.

Noise Reduction

Integrated elastomeric rubber gaskets between the aluminum support frames and cover plate cancel out metal-to-metal noise, enhancing acoustic comfort. This feature minimizes noise when subjected to movement, delivering a quiet and efficient joint cover solution for roof applications.
Noise Reduction

Durable Aluminum Profiles

The PROROOF Series utilizes high-grade AA 6063 aluminum for the support frames and cover plate, ensuring durability, corrosion resistance, and structural integrity. Its robust aluminum composition is designed to withstand exposure to environmental elements over prolonged periods.
