Tensioned inside the rails Unlike a basic roller blind, zipped fabric edges lock into side guides. This limits excessive movement and helps retain the screen under wind.

Solar and glare control Technical fabrics filter sunlight, reduce glare and limit overheating. External shading is effective because it intercepts solar energy before it reaches the glass.

Privacy Depending on openness, fabric can reduce daytime views from outside while preserving some outward visibility. Night-time privacy changes when interior lights are on.

Pergola integration Zip screens control low-angle sun and wind on the sides of a pergola. Planning motor and cable routes before production gives a cleaner result.

Selecting fabric Colour, openness, UV resistance and fire behaviour should match the application. Wide openings require coordinated wind, profile and motor calculations.
