Extra Wide Roller Blinds

Engineered for Large Spans — Designed to Perform, Not Just Fit

Wide roller blinds look simple, but once you pass around 3000mm, everything becomes engineering: tube stiffness, fabric stability, headbox design, and long‑term reliability. At Taylor & Stirling, we design extra wide blinds using  Helioscreen, Vertilux, and our own custom 68mm system, selecting the right combination based on span, fabric, and performance requirements.

🪟 Where Wide Roller Blinds Work Best

Perfect for:

  • Sliding & stacker doors
  • Large picture windows
  • Open‑plan living
  • Commercial fit‑outs
  • High‑use areas needing reliable operation

⚙️ Understanding Width Limits — The Real Engineering Rules

1. The 3000mm Threshold

Once a blind exceeds 3000mm, several things change:

  • Tube diameter must increase
  • Fabric options narrow (only stable, low‑stretch fabrics)
  • Chain loads increase
  • Deflection becomes a major design factor

This is the point where we stop treating the blind as “standard” and start engineering it.

🧪 2. The 3225mm Practical Limit (Standard Internal Rollers)

For standard internal roller systems (non‑specialised tubes, standard brackets, standard headboxes), we treat 3225mm as the maximum practical width.

Why?

  • Tube deflection becomes visible
  • Fabric skew decrease
  • Telescoping risk rises
  • Chain loads exceed comfortable operation
  • Warranty becomes questionable

This applies to standard Helioscreen internal rollers, standard Vertilux rollers, and generic systems.

🧠 3. Helioscreen Internal Rollers — Up to 3800mm

Helioscreen can exceed the 3225mm limit when specific conditions are met:

✔ Maximum width: up to 3800mm

…but only when using:

  • Approved low‑stretch screen fabrics
  • Their upgraded, larger‑diameter tube
  • Correct bracket and fixing configuration
  • Motorisation (strongly recommended)

Helioscreen increased their tube diameter specifically to support these larger spans — but only with fabrics that behave predictably at width.

We follow their engineering tables exactly.

🧠 4. Vertilux OneScreen — Up to 12,000mm

Vertilux’s is able to offer a number of extra wide blind solutions, in standard configuration depending on fabrics 3400mm to 3900mm, but with the OneScreen system is a completely different category:

✔ Maximum width: up to 12,000mm

✔ Requires a special headbox

✔ Uses a specialised oversized tube

✔ Designed for commercial-scale spans

✔ Motorised only

✔ Limited fabric range (stable screen fabrics only)

This is not a “normal roller blind” — it’s a specialised architectural system.

We only specify OneScreen when the project genuinely requires a single span beyond 4–5 metres.

🛠️ 5. Taylor & Stirling Custom 68mm Tube System

For spans between 3000mm and 4200mm, we also offer our own engineered solution:

✔ 68mm custom tube

✔ Designed for internal wide blinds

✔ Works with selected screen fabrics and some blockout fabrics.

✔ Reduces deflection compared to standard tubes

✔ Ideal for large residential openings

This system fills the gap between standard rollers and the specialised Helioscreen/Vertilux systems.

🚫 What Goes Wrong When You Push Too Wide

Even with upgraded tubes, wide blinds introduce risks:

🔩 Tube Deflection

  • Bowing in the middle
  • Bottom rail not level
  • Visible rippling in fabric

🎯 Fabric Skew & Telescoping

  • Fabric walks sideways
  • Edges rub or fray
  • Fabric rolls unevenly

⛓️ Chain Load & Clutch Stress

  • Heavy to operate
  • Clutch wear accelerates
  • Chain safety compliance issues

🧱 Bracket & Fixing Load

  • Higher torque
  • Requires stronger substrates
  • Headbox stress increases

This is why we engineer every wide blind individually.

🎨 Fabric Selection for Wide Blinds

As width increases, fabric choice narrows.

✔ Recommended

🪟 Screen fabrics (2–5% openness)

  • Low stretch
  • Excellent stability
  • Ideal for spans above 3000mm

🌑 Selected blockout fabrics

  • Only those with stable cores
  • Must be compatible with tube size
  • Often require motorisation

❌ Avoid

  • High‑stretch polyester
  • Soft‑hand decorative fabrics
  • Heavy coated blockouts on large spans

Fabric choice is one of the biggest determinants of success.

⚡ Control Options

✋ Manual Chain

  • Suitable up to ~3225mm
  • Beyond that, chain loads become excessive

⚡ Motorisation

  • Strongly recommended above 3000mm
  • Essential for Helioscreen 3800mm
  • Mandatory for Vertilux OneScreen
  • Integrates with smart home systems

Motorisation improves operation — but does not fix deflection or fabric behaviour.

🔗 Alternatives for Very Wide Openings

When a single blind isn’t the best solution, we offer:

🔗 Linked blinds

  • Shared brackets
  • Reduced light gaps
  • Independent control

🧭 Multiple blinds in a run

  • Cleaner operation
  • Lower loads
  • Easier servicing

🌤️ External screens (Helioscreen)

  • Designed for large spans
  • Manage heat and glare outside the glass
  • Ideal for Hobart’s coastal glare and Ballarat’s summer sun

📍 Local Expertise — Ballarat & Hobart

We design wide blinds based on:

  • Local climate
  • Orientation
  • Glazing type
  • Fabric behaviour
  • Supplier engineering data
  • Our own 40+ years of installation experience

❓ FAQs

Can you make a 4m internal roller blind?

Yes — with Helioscreen or our 68mm custom tube, using approved fabrics and usually motorised.

Can you make a 12m blind?

Yes — Vertilux OneScreen supports up to 12,000mm with its specialised headbox and tube.

Why do you still talk about 3225mm?

Because that’s the limit for standard internal roller systems. Beyond that, you must move to specialised tubes, special fabrics, or special systems.

Does motorisation let you go wider?

It helps with operation, but it doesn’t solve deflection or fabric skew. Tube size and fabric stability matter more.
