How to order

Filler blocks for the Kingspan KS1000RW panel are available to order online for next day delivery here. All other profiles are made to order, so please call us on 0845 450 7483 or email sales@fixfast.com with your enquiry. Please have the below information to hand when you call:


1 - Which grade of material do you need?

Profiled filler blocks are available in two different materials: V-GRADE, which is polyethylene or EPDM, which is an EPDM rubber material. V-GRADE is the more popular and economic option used throughout the industry, whilst the EPDM rubber is a higher grade product. The key differences are outlined in the table below:

Product Density (kg/m) Expected service life Temperature range (0C) UV resistance Weathering resistance Ozone resistance
V-GRADE 33 Approx 15 years -70 to +105 Good Very good Good
EPDM 100 - 150 Approx 20+ years -56 to +70 Very good Very good Excellent



2 - Which flute do you need?

Filler blocks are available as large flute (fits over the sheet), small flute (fits under the sheet) or pairs which are both large and small flutes supplied together.


3 - Which panel profile should the filler block suit?

Filler blocks are available to suit any profile sheeting or composite panels. Please confirm the manufacture and the manufactures panel reference, for example; 'Kingspan KS1000RW'. From this, we will obtain from their specifications the exact dimensions of the filler block.

4 - How many do you need?

Please confirm the quantity in terms of length (meters) or pieces, in which case the length of the filler block will match the width of the panel. 

Additional options


1 - Rake-cut

Rake cut filler blocks are required where the sheet edge to be filled is at an angle. Please make sure you know the following information:

  • Pitch - the pitch of the roof
  • Plan angle - the angle of the edge as from above (for gable ends, just the pitch is required)
  • Left hand or right hand - which side of the angle the filler is to fit

The diagram shows the most common uses of for filler blocks and where rake cut fillers are required.


2 - Self-adhesive

Filler blocks can be supplied with a self-adhesive strip or mastic strip to aid positioning and sealing. Please specify which sealant is required and order 'mastic to base', 'mastic to profile', or 'mastic all round'.

3 - Extended base

Extended base filler blocks are used in applications such as composite panels where a deeper base is required. Please specify dimension 'a' (shown on the diagram) when ordering.
