Our fire-retardant polystyrene bead or bean filling is great for filling bean bags. The bean filling is available in bags of 3 cubic, 6 cubic and large 10 cubic bags. Polystyrene beads are also used in the construction industry as cavity wall insulation, injected with a suitable adhesive into wall cavities and can also be mixed with concrete to reduce its weight whilst increasing its thermal properties. Whether you've tried your creative hands at designing and making a new furniture addition to your living room, an adorably cuddly toy for your little one or a dreamy pillow, this filling bag will bring your creation to life!.
