Fillerboard Joint Strip 20mm x 200mm x 2440mm is an expansion joint filler strip, a multi purpose bituminous wood fibre based strip used as an expansion joint filler for concrete slab and wall construction.

20x200mm Fillerboard Jointing Strips packed in 6 strips per pack are highly resistant to moisture penetration and ice formation in joints and should be protected by a fuel resistant sealant.

Fillerboard Strips are used in expansion joints for concrete in such applications as roads, airport runways, pedestrian areas, floors, concrete roofs, external walls, cladding and slab pavement construction.

Wood Fibre Filler Board Strips remain permanently resilient and are resistant to dry and wet rot, fungus attack and other similar forms of deterioration if protected by appropriate sealant.

Expansion Joint Strips can be sealed using most cold applied polymeric sealants, but where liquid hydrocarbons such as shuttering oil, petrol, diesel fuels and other solvents may be present.

This wood fibre fillerboard strips are manufactured from wood fibres (pine) water, bitumen, waterproofing agents and paraffin in a wet process for use as an expansion joint in concrete applications.

The installation of expansion joint strips, such as Fillerboard in concrete, is required to relieve stress and thereby reduce the risk of cracking or heave in a slab.

It is a characteristic of concrete that it will expand or contract slightly relative to ambient temperatures.

In simple terms, concrete will expand in the summer and slightly contract in the winter.

Wood Fibre Fillerboard Strip is lightweight material which can be easily cut on site.

No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.


1. Thermal inspection picture in portfolio

It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.

2. Reviews

Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.

3. Compare prices

Comparing prices will also ensure companies can’t take advantage of you and give you a fair price. 

4. Word of Mouth

The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.
