Venetian Blind Systems

Slats, mechanism and ladder tape — the oldest and still most practical blind to adjust light to the millimetre.

Venetian Blind Variants

Three system forms — each described on its own page.

Horizontal Venetian Blind

The classic free-hanging form — headrail, ladder tape, tilting slats.

Cassette Venetian Blind

Closed aluminium casing — mechanism and connections hidden.

External Venetian Blind

A guided system on the building exterior — flexible slat, wind resistance.

Slat System Components

There is no fabric in a venetian blind — horizontal slats and the mechanism moving them build the system.

Slats

Horizontal strips tilt between 0–180° — light and privacy are adjusted to the millimetre. The system speaks through them.

Headrail/Mechanism

The headrail housing the raise (up/down) and tilt functions — the heart of the venetian blind.

Ladder Cord/Tape

The vertical link that carries and aligns the slats — a decorative tape option exists on wooden venetians.

Bottom Bar and Gathering

The bottom profile keeping the slats taut — height and tilt are controlled by cord or wand.

Material Types

Three material families — slat width and usage profile make the choice.

Slat dimensions and features of venetian blind material types
Material	Slat	Use	Note
Aluminium	16/25/50 mm	Modern, moisture-proof — kitchen and bathroom	20–30 micron slat thickness
Wood	25/50 mm	A warm, natural look — living room	Wood-look aluminium option
PVC	25 mm	Budget-friendly — easy cleaning	A fabric vertical variant is also available

Mechanism Options

How tilt and raise are controlled — four options.

Venetian blind mechanism types and features
Mechanism	Operation	Note
Wand + Cord	Tilt by wand, raise by cord	Standard and economical
Continuous Cord Loop	A continuous loop on one side	Large and heavy systems
Geared	Gear mechanism	A softer tilt feel
Motorised	Tilt and raise by remote	Hard-to-reach glazing

Questions About the Venetian Blind System

Which slat width is used where?

16 mm gives a minimal look, 25 mm is the general standard; 50 mm delivers a cleaner look on wide openings.

What is a perforated (punched) slat?

25 mm punched aluminium slats pass part of the light through as filtered light — preferred in spaces wanting filtered light rather than darkness.

Real wood or wood-look?

In humid environments wood-look aluminium delivers durability instead of real wood; in dry interiors the texture of real wood is chosen.

How is a venetian blind cleaned?

The slats are brought to the closed position and the surface is wiped with a damp cloth. Aluminium and PVC are moisture-proof; wood is wiped with a dry cloth.

The compatibility table of slat types with installation surfaces is listed on the Venetian Blind Installation Types page; the spaces the system works in are listed in the application areas.

Let Us Pick the Material

Once the room's moisture state and look preference are relayed, material and slat recommendations are given.
