Structural insulated panels from Vencel Resil have been used to meet the latest U-value requirements at a converted and extended 16th century barn in Suffolk.
Walnut Tree Farm uses Jabroof SlimFix roof panels, a system that consists of a sandwich construction incorporating an inner and outer layer of 8mm thick moisture-resistant orientated strand board (OSB) bonded to an insulating core of expanded polystyrene, which provides a ‘warm’ roof construction.  
Jabroof SlimFix, which has been approved by the British Board of Agrement (BBA), is being widely specified in major housing developments for its thermal performance benefits as well as its ability to help housebuilders meet their build schedules.
Polly Wellings from Walnut Tree Farm said: “The roof panels were extremely easy to handle and work really well with the rest of the building. 
“We completed the installation of the roof in just two days, when normally it would take much longer. The result is a property that has a traditional finish, but with all the benefits of modern methods of construction.”  
 Neil Conway, general sales manager for Vencel Resil, explained: “This is the perfect demonstration of how modern methods of construction are not just applicable to new builds, but also to renovations. 
“This type of construction is becoming really popular with developers who need to achieve the required U-values, reduce the amount of waste on site and meet ever tighter build schedules.”
