Alnet is proud to introduce EXTRABLOCK!

The innovative and specially designed UV Extrablock, a product with unique properties.

The Extrablock range of knitted shadenetting fabrics has been specifically designed for use in tension structures, but performs equally as well when used on standard carport structures, awnings and even umbrellas.

The Extrablock shadenetting is unique with its high tensile strenghts in the warp and weft directions as well as its almost equal elongation properties in both warp and weft directions when under tension.

Alnet researched and engineerd this remarkable shadenetting for almost two years, and now bring to the world a unique and extremely functional outdoor shadenetting, one that can offer the ultimate combination of:

• high strenght
• controlled elongation
• maximum shade
• dimensional stability
• maximum protection against harmful UV rays
• fire retardancy
• and exceptional resistance to UV degradation.

Extrablock is the result of the technological abilities and commitment of one of the world's first manufacturers of knitted shade fabric, Alnet (Ptyd) Ltd.

At present, Extrablock is available in 6 colours:
