It is ideal for use in bedrooms, living rooms, holiday apartments, hotels, offices, doctors' surgeries, therapy rooms, clinics, care homes, and other sophisticated commercial spaces. It is perfect for spaces where aesthetics, well-being and thoughtful design are important.

Topas+ is an extremely light and air-permeable knitted curtain fabric that offers high- and low-frequency shielding. Its air- and light-permeability is almost 100%, preventing CO² build-up in canopies.


Ultra-fine stainless steel filaments provide the shielding. This protects the fabric against mechanical stress and corrosion. Thanks to these filaments, the knitted fabric is antistatic.


Topas+ is primarily used as a curtain fabric for windows and doors, for partial wall screening and for bed canopies and insect screens.


Due to its fine, open weave and ultra-fine stainless steel filaments, this material may curl or change texture slightly after washing. However, this does not affect the material's functionality or sun-protective properties.


We therefore recommend a gentle wash to avoid excessive mechanical stress. The slight creasing typical of this fabric can usually be significantly reduced by hanging the garment up while it is still damp and gently stretching and steaming it.
