Our membranes


Synthetic membranes are designed to waterproof all shapes and types of roofs. They are primarily intended for flat roofs, but are also used for creating curved or sloped roofs due to their aesthetic qualities.

The main advantages of synthetic membranes are:

Competitiveness:

  • Savings on implementation: a single layer, whereas bituminous waterproofing is made of a two-layer system.
  • Savings on structure: waterproofing is more than five times lighter than multi-layer solutions.
  • Maintenance savings: generally limited to checking gutters and downspouts.

Fire Safety:

  • No open flame used during the assembly of the membranes.

Aesthetics:

  • Uniformity of the roof thanks to the discreet overlaps.
  • Wide range of colors.
  • Adaptability to roof structures of all shapes.

Physical Properties:

  • Water vapor permeability.
  • Flexibility.

Durability:

  • Life expectancy, according to the BBA (British Board of Agrément), is over 35 years.

Recyclable:

  • PVC is recyclable and can be reintroduced into a new manufacturing process, helping to preserve our environment and natural resources.
  • End-of-life PVC roofing membranes can be collected and recycled into new raw materials.
  • Our supplier RENOLIT, aware of its ecological responsibility, participates in the ROOFCOLLECT collection and recycling program.

Insulation


The insulation of a flat roof helps prevent up to 30% heat loss within the building. This is an essential aspect of saving on energy bills. Additionally, proper insulation ensures a better living environment by improving thermal comfort in both summer and winter.

The choice of thermal insulation for a flat roof depends on the nature of the physical support, the required performance, the chosen waterproofing technique, and the type of roof.

Insulation for a flat roof is generally applied from the outside, offering better building insulation. Materials such as expanded polystyrene, polyurethane, extruded polystyrene, and rock wool each have their own qualities to meet all performance requirements (thermal insulation, sound absorption, resistance to compression or humidity) for both new construction and renovation projects.

We will find the appropriate insulation to meet your needs, constraints, RE 2020 regulations, and your thermal study.
