Chester Zoo

Chester Zoo is one of the UK's largest zoos with more than 27,000 animals on a 128-acre site. Visited by around 2 million people every year, many of whom choose to eat at June's food court.

The restaurant has a pavilion-like structure with an unusual roof comprising nine hexagonal peaks linked by seven flat areas.

The Challenge:

Water ingress through the old roof had forced shut down of the café multiple times making it necessary to renew the entire buildup. The beautifully designed trapezoidal featured roof was hugely complex.

The extremely intricate design process involved SIG as system experts alongside Tapered Plus in designing the cut to fall scheme that achieved the correct U-Value for the new roof.

Unilin Insulation’s Solution:

Our TR/MG product is a high performance polyisocyanurate with mineral coated glass facers which is suitable for use below single ply waterproofing system. It is also compatible with partially bonded built-up felt and many liquid waterproofing systems. In addition, the insulation boards are easy to handle, cut, and secure with insulation adhesive or mechanical fixings. The specifications and quantities met U-Value of 0.18W/m2K, which is required by the updated Building Regulations Part L.  (published in 2021).
