The patented FILON Over-roofing system has an incredible range of benefits for building refurbishment – from time and cost savings to reduced environmental impact and more. Utilising durable profiled GRP sheets, FILON Over-roofing is designed to provide a quick, trouble-free and economical solution for a new waterproof skin over an existing roof, whatever its condition.
BENEFITS OF FILON GRP OVER-ROOFING
Time
Building refurbs can take time, but FILON’s Over-roofing system can save you some in a number of ways:
Cost
Budgets are always a concern in any refurbishment project. FILON Over-roofing:
Minimal weight
FILON Over-roofing is lightweight yet strong, and is manufactured to the same profile as the existing roof. It therefore requires no additional structural supports. As the weight of the system is less than that of the potential water absorbed by the existing asbestos cement and fibre cement sheets, there is no requirement for structural calculations. The building will have carried heavier loads under saturation before, but the existing sheets won’t get wet again.
Minimal disruption on-site
Fixed from the outside, FILON Over-roofing allows total roof refurbishment to be carried out with minimal disruption to building occupants.
The cover width is the width to use to calculate how many you require, the difference between this and the overall width is to allow the sheet to lap onto the next.
Please Note: 25mm spacers can be added to your order as one, free of charge, per linear metre - you must let our sales office know these are required when ordering. 60mm spacers are also available but will be charged for - please contact our sales office for more information.
If you require under 50 linear metres please contact our sales office for a quote.
