Roofing & Cladding Support Systems

Gridtite

For all new build and refurbishment applications Gridtite is a long established, class leading spacer system with a proven track record. Tested extensively by independent laboratories and supported by a full technical package. Gridtite is ideal for roofing and wall cladding where the spacer system runs horizontally* across the wall or roof, supporting ‘top to bottom’ sheeting.

Gridtite is a lightweight bar and bracket system that is designed to provide a controlled space between the inner and outer metal sheets that make up “twin skin” site assembled roofing and walling systems. Insulation goes into this space – usually either a glass fibre or rock fibre quilt.

Gridtite is easy to install, strong and stable when sheeted over; is durable and easy to relocate or alter if the need arises. It is easy for self-drilling fasteners to drill into, but provides good fastener grip to resist pull-out loads. Gridtite has very little effect on the thermal performance of the insulation, which assists the building in complying with Part L of the building regulations.

* for wall sheeting that runs horizontally, use Gridtite GP.

  • Bracket

    Bracket

    Manufactured from 1.55mm high tensile galvanised steel to BS EN 10346-S390+Z275 incorporating stiffening ribs and vapour seal pad/thermal insulator.

    Heights available 60–220mm generally in 10mm increments. Other heights can be produced by arrangement.

    Brackets are boxed in varying quantities depending upon size; every box features simple, pictorial fitting instructions.

  • Ultra Bracket

    Ultra Bracket

    Due to thermal performance requirements, the depth of insulation specified has increased over the years. With this in mind Fixing Point have designed and developed our new Ultra Bracket.

    The improved design adds strength & stability to the bracket which allows for depths of up to 400mm without the need for additional support brackets.

    Manufactured from 1.55mm high tensile galvanised steel to BS EN 10346-S450+Z275.

    Heights avaialable: 140 – 400mm generally in 10mm increments.

    Brackets are boxed in varying quantities depending upon size; every box features simple, pictorial fitting instructions.

  • Bar

    Bar

    Manufactured from 1.25mm high tensile hot-dip galvanised steel to BS EN – 10346-S390GD+Z275 incorporating a 40mm spigot end for easy on-site connection to form a continuous level support.

    Corrugations along its length give strength, stiffness and optimum screw pull out performance.

    Lengths 1, 2, 3 & 3.6m (effective cover). Bar weight = 1kg/m.

    The bar length we quote is the finished ‘fitted’ length and ignores the 40mm joint. A pre-punched hole in both ends allows accurate alignment and, by inserting a fastener, a means to lock the lengths together in a more positive manner than a punched tab.

Gridtite GP

Gridtite GP is a lightweight bar and bracket system that is truly General Purpose. It is designed to provide a controlled space between the inner and outer metal sheets that make up “twin skin” site assembled roofing and walling systems.

Gridtite GP

GP is easy to install, strong and stable when sheeted over; is durable and easy to relocate or alter if the need arises. It is easy for self-drilling fasteners to drill into, but provides good fastener grip to resist pull-out loads.

GP has little effect on the thermal performance of the insulation, which assists the building in complying with Part L of the building regulations. Gridtite GP and Gridtite GT have been approved for use in firewall applications.

A multi-purpose rail and bracket system designed for high load applications such as horizontal wall cladding, extra wide roof light spans and flat to pitch conversions.

Please enquire for a copy of our fire assessment report.

GP Brackets should be fitted over the crown of the liner panel and not in the valley.

Benefits

  • User friendly high strength design.
  • Resolves horizontal cladding issues.
  • Suits most profile-insulation-liner combinations.
  • Secure fixing detail.
  • Minimum components.
  • Suits any cladding rail spacing.
  • GP rails up to 4m long.
  • Range of bracket sizes to suit most U values.
  • Limited cold bridging.
  • Non-combustible.
  • Compliments Gridtite GT system.
  • Brackets can be either pre-assembled into the bars, or attached to the structure individually – it’s your choice. Pre-assembly removes the risk of misalignment of fixed brackets.
  • No loose spigot sections are required. Simply butt bar sections up to each other on the appropriate brackets.
  • Brackets are solid and do not hinge.
  • Simple, single layer of quilt insulation is used, no confusion problems with two different quilt depths.
  • Line out the walls in the conventional manner.
  • If a fire wall is required fit Fire Insulations Hangers when installing the liner fixings. These can also be used instead of stick pins on a non fire wall if preferred.
  • Fix the assembled GP system to the sheeting rails.
  • Push the quilt over the hangers.
  • Install the outer sheet.

Gridtite GP Bar

Gridtite GP Bar diagram

Bar

Manufactured from 1.25mm high tensile hot-dip galvanised steel to BS EN 10345-S390GD+Z275.

The 40mm deep bar section is available in 3, 3.6 & 4m lengths. For ease of handling we recommend that double spans are used giving 3.6m lengths with horizontal rails at 1.8m centres.

The lengths of bar can be joined mid span by butting end to end over a splice joint or at a bracket location by using the wider butt bracket.

Two screws are recommended through the side of both sides of the bar into each bracket.

Bracket

Manufactured from 1.25mm galvanised steel incorporating a vapour seal pad / thermal insulator.

Heights available 100 – 260mm generally in 10mm increments. Other heights can be produced by arrangement.

Brackets are supplied in two widths:

Standard brackets: 50mm wide – for intermediate positions or at the end of a run.

Butt brackets: 100mm wide – where two lengths of bar butt against each other.

Assembly

GP is easy to assemble, brackets can either be fixed to the structure first and then the bar attached, or the two components can be assembled first and then secured to the structure.

All fixing is achieved using Drilltite self drilling and tapping screws.
