Wythenshawe Forum Case Study

Hosting a variety of retail, leisure and medical facilities, Wythanshawe Forum is a central hub for the local people. The Stone Roses, Lulu and Hot Chocolate have all showcased their tuneful talents within this historic community building, which is located in a city well-known for its musical pedigree. The thriving hub equally acts as a main transport terminus in Manchester with the Metro-link and bus services operating from this site, connecting Wythenshawe to the rest of Manchester and the North-West alike.

As an important community asset, Manchester City Council decided that for the centre to remain fully fit for purpose, a full large-scale re-rooing project would help to protect the building’s legacy for many years to come. The aging seventies roof was originally built up from Asphalt and limestone chippings, and in the late eighties it was decided that it should be overlaid with a full metal profile flat to pitched conversion. It was only within the past 10 years that the building began to suffer from various severe leaks, causing disruption and safety issues to the building’s users.

Bauder Building Board

Project: Wythenshawe Forum
Location: Manchester
Project type: Refurbishment
Roof area: 5693m2
Specifier: Manchester City Council
Approved contractor: LRL Roofing Solutions Ltd
Main contractor: F Parkinson Ltd
Solar PV installer: Absolute Solar and Wind Ltd

Systems Installed

The project entailed the installation of three separate roofing systems, primarily focusing around the Bauder BTRS Flatboard and Tapered System. The build-up of the central system consisted of four layers. The first layer was the BauderTEC KSD Mica sheet which was directly applied to the concrete roof deck. The material is tear resistant, aluminium lined and self-adhesive, which acted as the air and vapour control layer for the roof.

The second layer installed was the Bauder PIR FA-TE insulation which is faced on both sides with aluminium foil. This was bonded together with an adhesive to create a strong union and provided the building with greater energy efficiency by thermally upgrading to meet the current building regulations. 

Thirdly, the BauderTEC KSA DUO underlay was applied precisely on top of the insulation layer with self-adhesive elastomeric bitumen, bonding itself tightly to the build-up.

To complete the roofing system, a Bauder K5K cap sheet was torch applied by our experienced workforce, providing lasting watertight coverage. This waterproofing system has a service life in excess of 35 years as certified from the BBA. To work towards achieving carbon emmission reduction goals, it was decided to incorporate a solar array on the roof with Bauder's non-penetrative BauderSOLAR system

Further to this system, we additionally installed a Bauder Thermofol Single Ply roofing system to the swimming pool area. A Bauder cold applied liquid system was also used to repair the areas that were diffcult to reach and where liquid was the only practical solution.

System build-up

K5K Capping Sheet in Charcoal Grey K5K is a top quality, heavy duty, torch-applied SBS elastomeric bitumen capping sheet which features a spunbond polyester reinforcement to allow the finished product to cope with structural movement without fracture. The mineral finish provides protection against UV degradation. This product was specified in Charcoal Grey but is also available in Brown & Natural Slate.
BauderTEC KSA DUO KSA DUO is a technically advanced self-adhesive SBS elastomeric bitumen underlayer with “DUO” lap technology to ensure thorough sealing of lap joints, even in lower temperatures. The product features a glass lattice reinforcement for strength and stability and benefits from cleaner, safer and faster installation than traditional torch-applied membranes.
BauderPIR FA-TE insulation FA-TE is an extremely efficient PIR insulation board with aluminium foil facing on both sides. The top facing features a printed grid pattern to aid site cutting. It is lightweight and has zero ozone depletion potential.
BauderTEC KSD Mica Air & Vapour Control Layer KSD Mica is a technically advanced, robust, self-adhesive SBS elastomeric bitumen air & vapour control layer, with a mica finished upper surface to allow easy bonding of insulation using the specified Bauder Insulation Adhesive.

BauderSOLAR PV System

The BauderSOLAR PV System involves risk-free, zero penetration installation with a single source for integrated design of waterproofing and PV. The system weighs just 9-12.5kg/sqm and the panels are designed to create a 12º angle.

PV contractors, Absolute Solar and Wind Ltd, installed 365 JA 410w panels to give a system size of 150kWp.
