T-Pren on Recreational Centre, Calgary
Nearly 1000 metres of T-Pren gutter expansion joints were installed on the 28,000 sq.m. curved roof the Rocky Ridge recreational centre in Calgary, Canada.
The wide curved gutter required long special lengths of T-Pren, 9-18m long, and were installed in pairs to provide double the expansion movement. T-Pren forms a waterproof expansion joint, which eliminates the standard step detail and so reduces the number of rainwater outlets required.
T-Pren is a composite material made from neoprene and metal bonded under controlled factory conditions to ISO 9001 quality standards.
