Flat Roofing Solutions for Schools & Academies

Sika Liquid Plastics has been manufacturing flat roofing and waterproofing systems for over 50 years and have always put the the building occupier at the forefront of our technology and service. Our flagship product Decothane, has been the liquid applied roofing system of choice for schools, academies and education facilities for many key reasons.


One of the main factors in the specification of Sika Liquid Plastics on schools, academies and education facilities, is the fact that all of our products and systems are cold applied. Unlike other traditional membranes such as felt, asphalt and other bituminous products no hot works are carried out on site during installation. This is of vital importance to any occupied building, but is of particular importance for schools, due to nature and volume of occupants. It also means that your roofs can be installed or refurbished whilst occupants remain within the facilities.


In addition, Sika Liquid Plastics has recently launched ‘Decothane Ultra’, a low odour product that has been developed with patented technology, which has been tested by Odournet a team of independent leaders in sensory analysis, and scientifically proven to be low odour. This system ensures that during installation, we can reduce the risk of complaints regarding odour.

The points on the map above highlight a few project case studies and are not indicative of all works in this sector.

Case Studies

Stokesley School, North Yorkshire

Sika Liquid Plastics Decothane Ultra low odour, cold applied liquid roofing solution specified for school roof refurbishment.

The project was funded by the EFA's Condition Improvement Fund (CIF), with Sika and Northpoint Architects working closely with the school to prepare the technical specification and independent professional advice required for the bid.



All Saints Catholic Academy, Mansfield

A one and two-storey building on a sloping site with a roof area of 2,425m2 featuring several roof lights. The seal around the roof lights had failed, causing water ingress and the existing felt roof surface had reached the end of its serviceable life and required replacement. With Condition Improvement Fund (CIF) funding secured, Sika Liquid Plastics, advised on the technical specification for the project to address the specific requirements of the building and Decothane Ultra was specified, providing a low odour, cold-applied solution without any disruption to lessons or health and safety concerns on site..



Stoddart Building, Sheffield Hallam University

The building’s existing roof was made up of a series of pitched, profiled metal roofs with metal valley gutters, all of which were in need of refurbishment. The project itself would provide many challenges with the main one being the location of the Stoddart Building on a major road running right through the centre of Sheffield.



Trevelyan College

Trevelyan College combines teaching and residential accommodation in a distinctive building of 1960s construction, which features a complex network of 18 hexagonal roofs.

The Decothane Ultra 25 system’s low odour formulation provided the ideal solution for carrying out the project in an occupied building offering a robust, seamless finish that both addressed the thermal performance and waterproofing requirements of the structure while offering an attractive finish, visible from other buildings and the park landsurrounding the college.
