Collection: Insulated Shutter Slats

There are several different types of insulated roller shutter slats available, designed to suit varying opening sizes, security requirements, and thermal performance needs. The most common are insulated aluminium slats, which are lightweight, corrosion-resistant, and ideal for domestic garages, shopfronts, kiosks, and smaller commercial shutters. These are typically available in 44mm, 55mm, and 77mm profiles, with larger profiles offering increased strength and wider spanning capabilities.

For more demanding commercial and industrial applications, insulated steel slats provide greater strength, durability, and security. These heavier-duty slats are commonly available in 77mm, 95mm, and 100mm profiles and are designed for larger openings such as warehouses, factories, loading bays, and industrial units. Insulated steel slats are often specified where improved security and structural performance are required alongside thermal insulation.

Insulated slats are also available in different finishes and configurations depending on the application. Solid insulated slats provide maximum privacy, weather resistance, and thermal efficiency, while some insulated profiles can incorporate vision windows or glazing sections to allow natural light and visibility. The choice of slat profile will depend on factors such as door size, wind loading, frequency of operation, insulation requirements, and the level of security needed.

Roller shutter slats are the horizontal profiles that interlock together to form the shutter curtain. Over time, slats can become bent, dented, or damaged, often due to impact, attempted forced entry, or normal wear and tear. In many cases, damaged slats can be replaced individually, allowing the shutter to be repaired without replacing the entire curtain.

However, it is important that replacement slats match the original slat specification. Changing the slat profile, thickness, or material can affect how the curtain rolls on the barrel, the weight of the shutter, and how it travels within the guide rails.

When ordering replacement slats, two key measurements are required:

1. Cut Length (Slat Width)

The cut length is the width of the slat excluding the end locks.

This measurement represents the actual metal slat length before the end locks are attached.

2. Overall Width

The overall width is the full width of the slat including the end locks fitted on each side.

End locks help keep the curtain aligned within the guide rails and prevent the slats from moving sideways during operation.

To ensure accurate replacement slats:

• Remove one of the existing slats if possible and measure it directly
• Measure the cut length without the end locks fitted
• Measure the overall width including the end locks
• Identify the slat profile and height
• Check whether the slats are steel or aluminium

Providing clear photos and measurements can help ensure the correct replacement slats are supplied.

Replacing slats is usually possible when:

Only a small section of the curtain is damaged

The remaining slats are in good condition

The barrel, guides, and operating system are still functioning correctly

If the curtain has widespread damage or corrosion, replacing the entire curtain may be more practical.

Replacing roller shutter slats is often a cost-effective way to repair a damaged shutter, restoring both the appearance and security of the installation while avoiding the cost of a full shutter replacement.
