Project Details

Knauf Windliner was used to complete work on the external walls of Carlton Academy, a secondary school in Nottinghamshire in need of redevelopment. The school was awarded £2.6m, an investment that allowed them to build ten new classrooms on site to house a wide variety of subjects and service a growing catchment area.

The project was designed by CPMG Architects, with Henry Brothers as the main contractor and WD Drywall specialist contractor installing the exterior walls.

"Windliner is our preferred option due to the ease of installation compared to other sheathing boards. It can be cut with a knife, so no need to set up expensive saws and extractors. The screws pull in with ease and the Windliner Tape provides a good seal even in moist conditions."  Ryan Doherty, Commercial Director, WD Drywall.

Knauf’s high performance Windliner board enabled the building envelope to be sealed quickly and easily, and the internal works have now started.

Developed for steel infill construction methods, Knauf Windliner is a specialist gypsum-based 12.5mm external grade sheathing board specifically designed for use with external steel framing wall systems.  It is easily identifiable by its terracotta-coloured external paper finish.  The product inherits both fire and moisture resistance qualities with the paper providing a water repellent surface.  It can be left installed and exposed for up to 6 months on site before the need to complete the final cladding.

In addition Knauf Windliner offers many other on-site benefits including a quick and easy cutting method –simply score and snap the boards – and simple fixing using low-profile headed Knauf Windliner Screws.  There is no pre-drilling required, resulting in a faster installation compared to a traditional cement particle board.  Furthermore the boards themselves are also lighter than traditional cement particle boards, making them easier to handle and install on site.

Knauf Windliner can eliminate the need for a breathable membrane saving time and reducing installed cost.

CMPG Architects, praised the team at Knauf for their advice and technical expertise on the design of the project.

"The support from Knauf Project Specification Team on this project was invaluable. The technical drawings and details provide were a great help in the completion of Carlton Academy and the Knauf team were always on hand to assist." - Alex Walker, CMPG Architects.

When complete, the refurbishment of Carlton Academy will have included the construction and fit out of a new detached teaching block with classrooms, an office and toilets, along with an additional car parking area. The School is delighted that this investment will support its catchment and its families as they see its facilities improve and grow.
