Quick Summary
Choosing between perforated and solid roller shutters depends on what your shop needs most: visibility, security, privacy, airflow, appearance, or stronger after-hours protection.
For most customer-facing shops, perforated roller shutters are usually the better choice because they protect the premises while keeping the shopfront, products, lighting, and signage visible after closing.
Solid roller shutters are better for higher-risk sites, rear entrances, stockrooms, warehouses, workshops, garages, and commercial areas where privacy and full coverage matter more than display visibility. Both options can secure a shop when they are properly measured, specified, installed, and maintained.
The right choice depends on your shop type, location, stock value, opening size, council requirements, and how important your after-hours window display is.
At Redwood Shopfront, we install made-to-measure roller shutters for shops, restaurants, pharmacies, convenience stores, offices, warehouses, garages, industrial units, and commercial premises across London and surrounding areas.
This guide explains the main differences between perforated and solid roller shutters so you can choose the right system for your business.
What Are Perforated Roller Shutters?
Perforated roller shutters are made with small punched holes or openings across the curtain. These openings allow visibility, light, and some airflow while still creating a strong physical barrier over the shopfront. They are commonly used on:
- High-street shops
- Pharmacies
- Convenience stores
- Restaurants and takeaways
- Shopping centre units
- Salons and beauty clinics
- Showrooms
- Retail display windows
- Commercial units that need both security and visibility
The main advantage is that your shop does not look completely closed off after hours. People can still see your display, signage, lighting, and branding. This is why perforated and punched shutters are often preferred for customer-facing shopfronts.
What Are Solid Roller Shutters?
Solid roller shutters are made with closed metal slats that create a full physical barrier across the opening. They block visibility into the premises and provide complete coverage over doors, windows, access points, or commercial openings. They are commonly used for:
- Warehouses
- Industrial units
- Back entrances
- Stockrooms
- Service doors
- Workshops
- Garages
- Loading bays
- Higher-risk commercial premises
- Shops that need privacy after closing
Solid shutters are often selected when the main goal is stronger protection rather than display visibility. They are practical for areas where customers do not need to see inside.
Main Difference Between Perforated and Solid Roller Shutters
The biggest difference is visibility. Perforated shutters allow people to see into the shop, while solid shutters block the view completely. This affects security, appearance, planning approval, lighting, branding, and how the shop feels after closing.

Which One Is More Secure?
Both options can improve shop security, but they protect the premises in different ways.
Solid roller shutters usually provide stronger full coverage because the curtain is closed and there are no visibility holes. This makes them useful for high-risk areas, industrial openings, stockrooms, and back entrances.
Perforated roller shutters still provide strong protection, but they are designed to balance security with visibility. They help protect the glass and entrance while allowing people to see inside. This can be useful for natural surveillance because security staff, passers-by, or police can see if something looks wrong inside the premises.
In reality, security is not only about whether the shutter is perforated or solid. It also depends on:
- Shutter material
- Curtain profile
- Side guides
- Bottom rail
- Locking system
- Motor quality
- Fixings
- Installation quality
- Glass type behind the shutter
- Maintenance condition
- Site exposure and risk level
A poorly installed solid shutter can perform worse than a properly installed perforated shutter. The specification and installation quality matter as much as the shutter type.
Which One Looks Better on a Shopfront?
Perforated roller shutters usually look better on customer-facing shopfronts because they keep the frontage feeling more open, active, and visually connected to the street after closing.
A fully solid shutter can make a shop look closed off, especially on high streets, shopping parades, town centres, and streets with regular foot traffic. This may be fine for rear entrances, warehouses, or stockrooms, but it is not always the best choice for a visible retail frontage.
Perforated shutters can also be more suitable where the appearance of the shopfront matters to landlords, shopping centres, or local councils. They help reduce the “blank wall” effect that solid shutters can create, especially in busy commercial areas or visually sensitive locations.
Solid shutters still have their place, but they are usually better where security and privacy matter more than street appearance.
Which One Is Better for Product Visibility?
Perforated roller shutters are better for product visibility because they allow people to see your window display, lighting, signage, offers, and branding after the shop has closed.
This is useful for businesses that rely on passing foot traffic, window displays, or after-hours brand exposure. Even when the premises is closed, the shopfront can still show what the business sells and keep the brand visible from the street.
Perforated shutters are especially useful for display-led businesses such as fashion shops, pharmacies, mobile phone shops, salons, cafés, restaurants, showrooms, and shopping centre units.
Solid shutters block the display completely. That may be acceptable for stockrooms, rear doors, loading areas, or high-risk access points, but for many customer-facing shops, it means the business disappears from the street once the shutter is down.
Which One Is Better for Privacy?
Solid roller shutters are better for privacy.
They fully block the view into the property, which can be useful for businesses that do not want stock, equipment, tools, vehicles, or internal layouts visible from outside.
Solid shutters are often a better choice for:
- Warehouses
- Storage rooms
- Workshops
- Commercial garages
- Staff-only areas
- Rear entrances
- Loading bays
- Industrial units
- High-value stockrooms
Perforated shutters provide limited privacy, but they are not designed to fully hide the inside of a premises.
Which One Is Better for Airflow and Light?
Perforated shutters are better for airflow and light because the small openings allow some ventilation and natural or artificial light to pass through.
This can be useful for:
- Food shops
- Cafés
- Restaurants
- Shopping centre units
- Internal retail shutters
- Car parks
- Commercial areas that need airflow
- Spaces where lighting should remain visible
Solid shutters block most airflow and light. That can be useful for privacy and weather protection, but it may make the shopfront feel darker and more closed.
Airflow and visibility are especially useful for customer-facing shops, food businesses, car parks, and commercial spaces where a completely solid shutter may feel too closed off.
Which One Is Better for Planning Permission?
Planning is often overlooked, but it can affect the type of shutter a shop is allowed to install.
In London and many UK town centres, external roller shutters can affect the appearance of a shopfront. Some councils are cautious about shutters that make streets look closed, inactive, or unsafe after trading hours.
Perforated, punched, lattice, or open-style shutters are often easier to justify because they keep some visibility through the shopfront. Solid external shutters may face more objections, especially on high streets, conservation areas, listed buildings, or visually sensitive locations.
That does not mean perforated shutters are always automatically approved. Planning rules vary by borough, building type, street location, and whether the shutter is internal or external. Before installing external shutters, shop owners should check:
- Local council planning rules
- Conservation area restrictions
- Listed building status
- Landlord or lease requirements
- Shopping centre rules
- Whether the shutter is internal or external
- Whether the shutter changes the shopfront appearance
Are Perforated Shutters More Expensive Than Solid Shutters?
Perforated roller shutters can sometimes cost more than basic solid shutters because the curtain design is more detailed and may require a more specific finish.
The final cost depends on opening size, material, motor size, controls, finish, access, security level, and installation requirements. Main cost factors include:
- Width and height of the opening
- Internal or external installation
- Steel gauge and curtain profile
- Powder-coated finish
- Guide rail strength
- Bottom rail and locking system
- Motor and controls
- Site access
- Removal of old shutters
- Planning or drawing requirements
A small shopfront shutter will cost less than a large double-fronted retail unit or industrial opening. The best way to compare cost is to measure the opening properly and quote both options based on the same specification.
Maintenance: Which Shutter Is Easier to Look After?
Both perforated and solid shutters need regular maintenance, especially if they are used daily.
Solid shutters are generally simpler in design because there are no punched openings across the curtain. Perforated shutters may need slightly more care to keep the holes clean and maintain the finish, especially in busy high-street or food environments. Basic maintenance should include:
- Checking the shutter opens and closes smoothly
- Cleaning dirt from guides and slats
- Listening for unusual motor noise
- Checking locks and controls
- Looking for dents or curtain damage
- Checking weather exposure and corrosion signs
- Booking servicing if the shutter becomes stiff, noisy, or uneven

Need help choosing between perforated and solid roller shutters?
For most customer-facing shops, perforated roller shutters are the better choice because they protect the premises while keeping products, signage, and lighting visible after closing. Solid roller shutters are usually better for rear doors, stockrooms, warehouses, garages, and higher-risk areas where privacy and full coverage matter more.
Redwood Shopfront does not recommend the same shutter for every business. We assess your shopfront, opening size, location, stock value, access points, visibility needs, daily use, and security concerns before recommending the right system.
We install made-to-measure roller shutters for shops, restaurants, pharmacies, offices, warehouses, garages, and commercial properties across London and surrounding areas.
FAQ
Are perforated roller shutters secure?
Yes, perforated roller shutters can be secure when they are properly specified and installed. They provide a physical barrier over the shopfront while still allowing visibility through the curtain. For higher-risk shops, reinforced guides, stronger locking, laminated glass, and a suitable security rating may also be recommended.
Are solid roller shutters better than perforated shutters?
Solid roller shutters are better for privacy, full coverage, warehouses, back entrances, and higher-risk areas where visibility is not needed. Perforated shutters are better for customer-facing shopfronts because they protect the premises while keeping products and signage visible.
Which roller shutter is best for a high-street shop?
For most high-street shops, perforated roller shutters are the better choice. They provide security without fully blocking the shopfront, helping your display, lighting, and branding remain visible after closing.
Do solid roller shutters need planning permission?
External roller shutters may require planning permission because they change the appearance of the shopfront. Solid shutters can face more planning concerns in some high-street, conservation, or town centre locations. Always check local council rules before installing external shutters.
Are perforated shutters good for restaurants and takeaways?
Yes, perforated shutters are a good option for restaurants and takeaways because they secure the shopfront while keeping signage, menus, and lighting visible after closing. Solid shutters may be better for rear doors, storage areas, or service entrances.
Which shutter is best for pharmacies?
Perforated shutters are often a good choice for pharmacies because they balance visibility and security. They allow customers to see signage, opening hours, and internal lighting while still protecting the entrance and glazing.
Can I use both perforated and solid shutters on the same premises?
Yes. Many businesses use perforated shutters on the main shopfront and solid shutters on rear doors, stockrooms, loading areas, or other non-customer-facing openings. This gives better security without making the main frontage look closed off.
How do I know which shutter my shop needs?
The best way is to assess your shop type, stock value, location, opening size, planning restrictions, and visibility needs. Redwood Shopfront can inspect your site and recommend whether perforated, solid, insulated, or industrial shutters are the right fit.
