Project Details

The renovation of St. Joseph’s Primary School in Bishop’s Stortford required an external sheathing board offering BBA certification for the project. Encon Insulation and Nevill Long knew exactly where to look for a suitable and cost-effective solution – Knauf Windliner


The project is scheduled to be completed this Summer, but the Coronavirus pandemic made this a challenge. However, with the help of the Knauf Technical Team, the development is well back underway.


“Sourcing a product to meet the requirements throughout the Coronavirus pandemic was challenging but working with the Knauf Technical Team we quickly determined that Knauf Windliner sheathing boards would meet performance criteria and would be available and delivered to site when required.” – Dan George, Area Sales Executive, Encon Insulation.


Knauf Windliner sheathing boards were supplied to the project by Encon’s East London Branch. Offering BBA certification and no requirement for a breathable membrane, the Knauf Windliner sheathing boards can be left uncovered on the façade for up to 6 months and can be used alongside Knauf Windliner Tape and Knauf Windliner Screws as a full system.


Subcontractor Eden Facades were looking for an external sheathing board that was lightweight and offered a fire reaction class A2-s1 d0 for the renovation project. Knauf Windliner ticked all the boxes, as it has a fire and moisture resistant core, and is faced with treated terracotta-coloured paper to reduce moisture ingress.


Rebuilding the 420-pupil primary school is a major refurbishment project. The new school is being built by main contractor, Kier, on the existing campus after the original 1960s school buildings were demolished. The school renovation allows space for a new external soft and hard play area, a coach drop-off point and a re-modelled car park with an extra 20 spaces for teachers and parents.
