Product description
SphereCore S (4 mm) is a lightweight glass veil-based core material that adds extra thickness and stiffness to your polyester or vinyl ester product without adding unnecessary weight. Once saturated with resin, the material becomes soft and highly conformable. This allows the material to overlap seamlessly and ensures excellent bonding with the surrounding fibreglass layers.
SphereCore S is also the ideal choice for achieving a smooth, high-quality finish. It prevents the structure of underlying layers, such as heavier fabrics, PVC foam or balsa, from showing through on the surface (print-through). The material is mainly used in hand lay-up applications for both flat panels and moulded parts, such as scooter panels, automotive body parts, pond liners, boat decks and boat roofs.
Benefits of SphereCore S
- Adds extra thickness and stiffness with minimal weight increase.
- Quickly absorbs resin, offers controlled resin consumption and can easily be cut to size with scissors.
- Becomes soft and highly conformable after resin impregnation, allowing seamless overlaps.
- Prevents print-through of underlying fabrics or core materials.

The measurement across a product from one side to the other, for example for rolls, panels or fabrics. With rolled materials, the usable width may differ from the overall width.
- 1.000 mm
-
The physical thickness of the supplied material, such as a panel, pad, film or foam sheet. This differs from the thickness of a liquid coating applied to a surface.
- 4 mm
-
Resin consumption indicates how much resin is required to properly wet out a reinforcement material. It may be stated in g/m² (grams per square metre), g/m for narrow fabric tapes or as resin quantity relative to dry fibre weight. Actual use depends on fibre type, areal weight and laminating method.
- Approximately 2.400 g/m²
-
Areal weight is the weight of one square metre of dry reinforcement, expressed in g/m² (grams per square metre). For example, 200 g/m² glass fabric contains 200 grams of dry fibres per m², without resin. Areal weight helps with reinforcement selection and resin consumption estimates, but it is not the final laminate thickness.
