Single-Ply Technology

We are proud to install single-ply membranes, including Sikaplan, IKO Armouplan and Protan roofing membranes. Ideal for almost any kind of roofing project, single ply is a highly versatile and strong roofing option.


What is Single-Ply?

Single ply is a complete roof system that is created from strong and flexible membranes composed predominantly of synthetic polymer. They are sealed at joints to form a continuous waterproofing layer and when combined with insulation and continuous support they form complete, durable roof systems.

Single-ply technology offers maximum freedom of choice in roof design, performance and appearance to suit new construction and refurbishment.

UK designers and specifiers have been using single-ply roofing systems for over 40 years, with this technology offering a huge range of geometric and performance options. And its versatility and durability, combined with excellent sustainability credentials, account for the rapid increase in use of this roofing system in the housing sector, whether in new build or refurbishment.


Reasons to choose Single-Ply

  • Rapid construction allowing early interior fit-out
  • Low capital cost and cost-in-use
  • Safe, flame-free construction using hot-air welding, adhesives and fasteners
  • High thermal performance using lightweight, thermally efficient rigid insulation
  • Cold bridging eliminated by use of thermal break fasteners
  • Effective control of air leakage to meet new energy efficiency regulations
  • Minimum roof zone depth to maximise design freedom
  • Easy repair, modification and refurbishment
  • Simple detailing to suit all situations
  • Interfaces to other construction elements
  • Various colour options with matching profiles for eaves, verges and parapets

Single-ply roofing systems are also an attractive alternative for refurbishment of old traditional flat roofing materials, and can also be an economic and aesthetic solution to failed lead roofs.

Alternatives to Single Ply

Liquid Applied Membranes
Liquid-applied membrane (LAM) is a monolithic, fully-bonded, liquid-based coating suitable for many waterproofing and roofing applications. The coating cures to form a rubber-like elastomeric waterproof membrane and may be applied over many substrates, including asphalt, bitumen and concrete.


Building on Sika’s trusted expertise as a global leader in roofing solutions, SikaBit® complements the Liquid Applied Membranes and Single Ply Membranes in the Sika portfolio, with a suite of advanced Bituminous Membranes, offered with the same high standards of technical support and customer service.
