Filler Board
Filler boards are made from highly flexible softwood fibers coated with Bitumen. These boards are dry and clean, resistant to any form of staining. They provide excellent moisture and frost resistance at joints, and are impervious to dry or wet rot, fungi, and most types of insect attacks or similar deterioration. They fully fill joints even under repeated cycles of expansion and contraction with minimal extrusion.
They also serve as an effective vapor barrier and are easy to handle without breaking.
Available thicknesses: 9, 12, 18mm.
