Hexagon Tower Case Study

The project

Hexagon Tower is a specialist science and technology facility located in North Manchester. The roofs of the laboratories were experiencing water ingress due to poor original detailing and aged interfaces. Whilst looking to replace the failing roof, the client also wanted to upgrade the insulation to increase the U-value and improve the appearance of the rooftop using a trusted system. Bauder was selected as the supplier due to its comprehensive service offering, which includes detailed report, bespoke specification, project advice and ongoing inspections to ensure a full system guarantee can be issued.

Project: Hexagon Tower
Location: Manchester
Project Type: Refurbishment
Roof Size: 6,000m²
Client: IF Building Consultancy 
Approved Contractor: BBR Roofing

The challenge

The building was occupied by employees during the works with multiple trades onsite. Bauder provided a system and installation methodology, to keep disruption to a minimum for both the employees within the building and the residents of the surrounding areas. The sensitive nature of the work being carried out within the building meant that mechanical and electrical equipment could not be switched off for more than a few hours at a time.

The solution

Elements of the existing roof surface were removed, details modified and then a Bauderflex system incorporating vapour control layer, 120mm PIR FA-TE insulation and two-layer bitumen waterproofing, with a brown finish was installed. BBR Roofing installed the system, finishing the roof area with expertly installed complex detailing around columns, windows and the area protected with a new free-standing guard rail.

Applied products


Bauderflex is suited to new build and refurbishment applications and is robust enough to withstand foot traffic and most permanently sited plant. It can be used in warm and cold roof designs and also to overlay existing roofing materials.
