Creative and versatile

Discover our wide standard range of lightweight and rigid sandwich panels suitable for advertising, signage, decorations, POS/POP displays and more.

KAPA® boards are a composite of polyurethane foam and various paper surfaces, some of which are FSC® certified. The boards are available in a range of colours from white and gray to black. There are variants with self-adhesive or moisture-repellent surfaces while others have a particularly stable foam core. The diverse range of boards is used primarily in the field of visual communication.

The easy processing of KAPA® foam panels is another benefit, which also applies to FOAM-X® and the extremely stable GATORFOAM® panels.

For short-term outdoor use (1 - 2 days) we recommend KAPA® plast - for long-term outdoor use we recommend the weatherproof, lightweight and  extremely stable SMART-X® plastic sheets.

Frequently asked questions about lightweight foam boards

Lightweight foam boards consist of two different components: A core of polyurethane foam with paper surfaces on both sides. Therefore these lightweight and stable boards are also called sandwich boards. Due to a wide product range with different properties, the boards are used in a wide variety of visual communication applications.
Both kinds of boards are light and stable, but the foam of rigid foam sheets is usually denser than that of lightweight foam sheets and so even more stable. In addition, the denser foam does not absorb water, which is why rigid foam sheets such as SMART-X® are often used in outdoor applications.
The advantage of the hardware store is that the boards can be picked up directly if they are in stock. However, it must be considered that transporting large & sensitive boards is not straightforward! Therefore, buying lightweight foam boards online is not only more convenient but also safer, as the boards are professionally packaged and delivered within 1-3 business days. As wholesalers, we not only have a variety of different lightweight foam boards permanently in stock, but also countless thicknesses and formats - sometimes even exclusive special formats!
Photos, pictures and posters can be laminated onto light foam boards such as KAPA® line using spray adhesive. Alternatively, you can use the self-adhesive KAPA® fix quick laminating boards (video instruction).
KAPA® tech boards are certified according to Euroclass Bs2dO / DIN EN 13501-1 (flame retardant / B1). Furthermore, the products KAPA® fix and KAPA® mount are certified according to fire protection class DIN 4102/B2.
