This new collection of blackout duo roller blind fabrics includes around ten fabric options, making it easier to choose the right finish for your interior and preferred level of light control.
If you want to make a room as dark as possible, it is important to consider how the system is installed. A duo roller blind system is approximately 40 mm wider than the fabric itself. For the best result, it is recommended to install the system outside the recess, with enough overlap. We advise at least 5 cm on each side to improve the blackout effect.
Please also note that duo roller blinds provide around 85% blackout on average. Because there is always some space between the two fabric layers, limited light diffusion can still occur between the bands and along the sides.
Still unsure about the right fabric or colour? Simply order free samples through our webshop, so you can confidently choose the right fabric for your made-to-measure duo roller blind.
Always read the installation guide before starting. This helps you prepare properly and follow the right steps for a correct installation.
As an online shop, we do not know your specific installation situation. For this reason, screws and wall plugs are not included as standard. The correct fixing materials depend on the surface, the weight and the intended use of the product.
