Why choose a fibreglass Composite construction?

It is difficult to categorize components produced using fiberglass reinforcement constructions. This is due to the many advantages given by choosing just such a solution. Fiberglass composite products are thus utilized in many different types of industries, with windmills and the boating industry being some of the best known.

Below are few of the many advantages, which can be achieved by choosing a fiberglass composite solution:​

  • Great pliability
  • Great strength with light weight
  • Extreme corrosion resistance
  • Fire resistance
  • Chemical resistance
  • High surface finish - UV resistance
  • Durable surface
  • Sound and heat insolating
  • No or very little maintenance
  • Long product life​

How is a fiberglass composite construction built up?

A fiberglass lamination usually consists of three (3) component elements. If one wishes to take advantage of the benefits of a sandwich construction, a fourth element is employed: sandwich materials.


Gel coat is used when a certain surface finish is required. Otherwise, a top coat is used when the exact requirements for a surface are of less importance.

Gel coat and top coat can be found with different qualities and in every conceivable RAL colour.


As a filling material, polyester is most often employed, but vinyl ester or phenol can be used according to the mechanical and chemical requirements placed upon the fiberglass lamination.

Fiberglass reinforcement

Fiberglass comes in many different varieties, such as chopped mats, specially woven or stitched mats and more fluid patterns. The choice of fiberglass reinforcement typically depends on requirements for mechanical strength and the choice of production process.

Sandwich materials

The use of sandwich materials in a fiberglass construction is usually present when one wishes to achieve a sound and/or temperature isolating effect. Additionally, a sandwich construction gives great advantages when strict requirements are placed upon weight and strength relations. As sandwich materials, PUR foam, XPS foam, PVC foam or balsa wood can be employed.
