What are single ply insulated panels?

Single-ply insulated panels provide a flat roof solution and comprise of three main components: a single-ply membrane, insulation core and liner sheet. The composite element of the panels provides an easy and quick solution, which rivals more traditional single-ply applications.

Not only do flat single-ply membrane panels significantly reduce installer's build time, but they also provide a high thermal performance whilst preventing moisture ingress and air leakage.

How do you fix single ply insulated panels?

To fix the panel, a fastener is required to secure the liner sheet into the substrate below.

Often referred to as 'self-coring fasteners', the prominent feature of single-ply membrane fasteners is their 'self-coring washer'. This washer facilitates the cutting of the membrane and coring of the insulation layer.

To achieve a successful installation a long drive bar is required to aid in the coring of the membrane and insulation, before fixing the liner sheet in place. The fastener could be required to fix the panel to light and heavy gauge steel, as well as fasten panel overlaps.

What are the key considerations when fixing single ply insulated panels?

In an ever-increasing carbon conscious climate, the maintenance of building's U-Value, has become a point of scrutiny during the design process, as a way of reducing the building's overall energy consumption in use.

Single-ply Membrane panels are no exception and key considerations during the installation stage are immensely influential in maintaining the panel's thermal properties.

Damage to the insulation layer must be minimised, throughout all the stages of the installation process, to ensure thermal performance is maintained.
A maintained connection with the fastener is essential for a successful installation. Using a drive bar with a secure fit prevents loss within the insulation layer as Reconnecting a lost fastener, results in further damage to the insulation.
Minimal damage to the membrane is required to allow successful welding of cover strip, fastener should cut through the membrane in one easy action. The swift cutting of the membrane, minimises the risk of the fastener faltering, resulting in interference with the insulation.
Reducing the diameter of the hole left in the membrane after installation assists with successful welding of cover strips, the head of the drive bar should have as small diameter as possible.

How does the new SXP range mitigate disruption to the insulation layer

SFS's new Stainless-Steel single-ply membrane fasteners have been designed with the above considerations in mind:

The SXP range have both a Hex and Torx drive, allowing installation with either drive. This flexibility allows for a more confident and controlled installation method. Providing increased security, reducing the risk of a lost fastener, leading to a successful installation. There are 'secure fit' drive bars for each of the head drive options.
The 19mm self-coring washers are designed to cut through the single-ply membrane with ease. They produce a 'corkscrew' motion during the coring of the insulation layer, providing a clear passage for the screw, crucially minimising disruption to the insulation.
Our accompanying drive bars have been designed with a reduced diameter and chamfer shape, to create a streamlined product, lessening unnecessary damage to the insulation and reducing the hole widths in the membrane.
