Roofing Systems

Sika can provide a Sarnafil solution for almost every type of roof design and options include:

Exposed Roofs

An exposed roof is where the waterproofing membrane is the visible finish of the roof. Sarnafil membranes offer excellent aesthetics in a variety of colour options and for adhered applications a fleece blanket membrane can be used which minimises the ghosting of insulation boards. Options include:

  • Sarnafast mechanically fastened roofing
  • Sarnabar mechanically fastened systems
  • Adhered systems

SarnaVert Green Roofing Systems

Green roof systems are often specified for numerous reasons such as management of incident rainfall or to replace the biodiverse footprint that construction destroys; creating a new habitat for both flora and fauna. Other benefits of green roof systems include amenity, thermal mass, absorption of carbon dioxide, resulting in pollution reduction, natural cooling and aesthetics. Sika recommend a Sarnafil warm ballasted system for the Biodiverse, Extensive and Intensive roof systems as it reduces the insulation thickness and effectively controls vapour diffusion. A Sarnafil AquaDrain drainage and protection layer will be installed prior to the installation of the SarnaVert planting. Through our branded product suppliers we will oversee the whole project to ensure correct system specification, construction, substrate formulation, water storage and nutrient levels, creating a balanced and sustainable surface for year round performance and environmental benefit.

Utility Roofs

Many of the Sarnafil single ply membranes are specifically designed to be used on utility roofs. The systems will provide durable, long lasting performance and resistance against biological micro-organisms. Utility systems utilise a loose laid membrane which is covered with a complex variety of build-ups and finishes to suit the final use, which is generally amenity purposes such as podiums and car decks.

Ballasted Roofs

Sika also offers a range of Sarnafil membranes for ballasted roofs. Ballasted roofs are applications where the membrane is restrained by means of either stone ballast or paving slabs.
