SureFast®

Tube washer and fastener system for flat roofing

Our SureFast fastening system comprises of a range of specialist tube washers, fasteners, pressure plates and termination bar for mechanically fastening insulation and/or membrane to flat roofs.

What makes up the SureFast range?

SF-T tube washers

Our SureFast tube system has been specifically designed to overcome the cold-bridging effect of mechanical fastenings.

Due to the thermal properties of SureFast tube washers, U-value calculations are greatly simplified - as minimal correction factors or penalties need to be considered, saving time at the design stage, and preventing any increase in material costs incurred by thicker insulation requirements.

  • Tubes to suit both insulation and membrane, providing a complete system

  • Comprehensive size range: available in lengths up to 250mm

  • Manufactured from high-quality polypropylene and able to withstand harsh rooftop environments

  • Up to 40 years warranty available for peace of mind

  • Barbed tube option to achieve high design values - sometimes results in fewer fasteners required

  • Pointed tube aids penetration through membrane and insulation

  • Low profile tube for use with Trocal® or TermBar

  • One tube diameter suits all fastener types 4.8-6.1mm diameter

  • 50mm diameter membrane tube for increased pull-over

  • Prevents the fastener head from damaging the membrane

  • Protects the deck and fastener interface

  • Effectively eliminates unwinding forces

Flat roofing components

Pressure plates

For insulation and membrane attachment in flat roofing applications, we have a variety of sizes and profiles to suit most applications.

Our pressure plates are ETA-approved and CE-marked, with stainless steel options for optimum corrosion resistance.

View the range

Termination bar

Available in 4 different profiles to cover the vast majority of applications, including the termination of membrane at parapet walls or penetrations.

Peel rivets

Designed for fastening insulation and membrane to thin metal decking materials and difficult substrates, in conjunction with SureFast pressure plates.

Anchor drive rivets

One-piece anchor for fastening flashings and TermBar to concrete or masonry - eliminating the need for separate fixings and plugs.

Steel grades

Carbon Steel

Carbon steel is suitable for use in internal or external applications in non-corrosive, non-coastal environments. All our carbon steel fasteners feature a corrosion-resistant organic coating which also provides lubrication for ease of drilling while also preventing damage to the steel.

Stainless Steel A4/316

A4/316 Stainless Steel is a super-austenitic alloy containing high levels of molybdenum, nitrogen and nickel – ensuring it is highly resistant to corrosion, tarnishing and stress

High Corrosion Resistant (HCR) 1.4529 Stainless Steel

Containing a minimum of 6% Molybdenum, these fasteners can be used in corrosive, aggressive environments

Head styles

Bugle

The tapered head style ensures the fastener sits nearly flush once installed – either on top of the substrate, or within a tube washer

Countersunk

Ribbed countersunk heads for an unobtrusive finish – with locking notches to firmly grip membrane once installed (available on our SF-RS-CL-5.2 range)

Tooling

SureFast drive bar

Drive bars at 750mm long allow the operative to stand whilst installing – with replaceable TX25 & 2PP drive bits, meaning the bar can be reused once the drive bit has worn out. Also available at 300mm long.

STOPP drills

Alongside our standard range of masonry drill bits are our specialist STOPP drills specifically for drilling an exact pilot hole depth. Use in conjunction with our Extender drill bar, for easy installation – allowing the operative to stand during installation.
