Supasafe, CEDR30 and CEDR24 translucent sheeting
DR-Refurb sheeting is an opaque light grey coloured repair or replacement sheet for defective asbestos cement or fibre cement sheeting. It is lightweight but tough with two layers of glass fibre reinforcement and can be used to sheet over a cracked roof sheet for example or to completely replace it. DR-Refurb sheeting can be used on any building that has a profiled asbestos cement or fibre cement roof.
Although DR-Refurb sheeting was originally developed for asbestos cement and fibre cement roofs, subject to enquiry, it can also be used to match old, profiled metal sheeting that is no longer available in a colour to suit.

Filon Over-Roofing
The Filon Over-Roofing system provides a refurbishment solution for old asbestos cement or fibre cement roofs when Building Regulations allow.
The Filon Over-Roof system is comprised of lightweight but tough, opaque grey profiled GRP sheeting that matches the existing roof profile, translucent rooflights when required, and 25mm deep or 60mm deep profiled Profix spacers that also match the existing roof sheet profile. The Profix spacers are designed to fit over the main hook bolt roof fasteners that are normally the type used and which are located at the back edge of the purlins, without removing them. The Profix spacer design allows new self-drill and tap roofing screws to be used into the central part of the purlin.
Accessories include a two-piece adjustable GRP ridge flashing for use on older roofs that have a close fitting, two-piece ridge and a 900mm girth GRP ridge flashing that can be used over a 900mm girth close fitting cranked crown ridge. Larger GRP ridge flashings and other flashings are available from Filon recommended suppliers.
The Filon Over-Roof system may be used on any roof that is clad with profiled asbestos cement or fibre cement roof sheeting.
Although originally designed for use on old asbestos cement or fibre cement roofs, the Filon Over-Roof system may be adapted for use on profiled metal roofs when alternative systems would impose too much load on the roof structure for example.

Filon Fixsafe
The Fixsafe system allows profiled rooflights or roof sheets to be replaced from within the building which eliminates the need to access a fragile roof. This also means that the need for costly roof access safety equipment is also eliminated.
The patented Fixsafe fastener system has been developed to accommodate most purlin and profiled sheet types and the tough and durable Fixsafe sheets are flexible enough to be manipulated into place without breaking.
The Filon Fixsafe system can be used to replace profiled rooflights or sheets for any roof where access on to it is not allowed, not preferred, or site safety is the prime concern.
