Filler blocks are used for sealing the cavities formed between profile sheet materials and flashings.
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.
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:
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.
4 - Double profile
These are filler blocks that are cut to match both outer and inner sheet profiles, normally used in built-up systems. Please specify dimension 'B' (shown in the diagram) as well as the manufacturer's profile references for both panels.
5 - Ventilated
Filler blocks can be supplied ventilated to facilitate air flow in the roof void by means of 'v-cuts', 'crown cuts' or holes, which can have mesh inserts if required.
6 - Side, block or custom shapes
As well as matching specific sheet profiles, virtually any size or shape of the filler block material can be manufactured. Square section or rectangular block are often ordered for side filler applications, and chamfered blocks can be specified.
