Domestic security grilles are installed where residential windows or doors are vulnerable to intrusion, particularly at ground level or in concealed locations around the property.

Ground Floor Windows

The most common application.

• Front facing windows
• Rear elevation windows
• Side alley windows

Provides protection against opportunist breakins.

Basement & Lower Ground Windows

Used on:

• Cellar windows
• Semi basement flats
• Lightwell windows

These openings are often at higher risk due to concealment and accessibility.

Patio & French Doors

Retractable grilles can be installed across:

• Sliding patio doors

• French doors

Allows secure closure overnight while maintaining visibility.

Rear & Side Access Points

Installed where doors or windows are:

• Not visible from the street
• Accessible via gardens or shared access routes

Helps secure areas that are typically targeted due to reduced visibility.

Apartments & Multi Occupancy Properties

Used in:

• Ground floor flats
• Converted houses
• Communal entrance glazing

Improves security without altering the building façade significantly.

Loft Conversions & Low Level Glazing

Where glazing extends closer to floor level and additional protection is desired.

Domestic security grilles are best suited to protecting vulnerable windows and doors around the home, particularly where there is increased exposure, concealment, or insurer-recommended security measures

Domestic Security grilles provide a practical and durable method of protecting vulnerable openings while maintaining visibility and ventilation. They are available from standard deterrent systems through to independently tested high security LPS1175 solutions.

Domestic Security grilles offer a cost effective, scalable security solution, from simple deterrent protection to certified high security systems, while preserving visibility, airflow, and architectural integrity.

Domestic security grilles must comply with relevant security certification standards, fire safety regulations, building regulations, and structural safety requirements, depending on their location and intended use.

Security Certification (Where Specified)

• LPS 1175 (Levels 1–3+)

Where enhanced protection is required, door security grilles can be specified to:

• LPS 1175 Issue 7 or 8
• Certified to graded security levels
• Independently tested by LPCB

Certification applies to:

• Grille construction
• Locking system
• Fixing method

Installation must follow the tested fixing detail to maintain certification.

Fire Safety & Means of Escape (Approved Document B)

If a door forms part of an escape route:

• The grille must not prevent safe and immediate egress
• Must not obstruct compliant panic hardware (BS EN 1125)
• Must not obstruct emergency exit devices (BS EN 179)
• Clear escape width must be maintained
• Security must never compromise life safety.

Retractable or hinged systems protecting escape doors may require internal release mechanisms.

Accessibility (Approved Document M)

Where installed along accessible routes:

• Must not reduce compliant door widths
• Trackless systems may be required to avoid trip hazards
• Threshold details must not create barriers

Bottom tracks must be carefully specified in public environments.

Structural Installation Requirements

• Must be securely fixed into structural substrate
• Appropriate anchor types must be used
• Installation must resist leverage and forced entry
• No reliance on non structural finishes

For certified systems, fixing must match tested specification.

External Durability

For externally installed grilles:

• Corrosion resistant finishes required
• Weather resistant fixings used
• Structural integrity maintained in exposed conditions

When correctly specified and installed, domestic security grilles can meet graded security certification requirements while remaining compliant with fire safety, accessibility, and structural safety regulations.

Domestic security grilles must be installed correctly to ensure structural integrity, smooth operation (where applicable), and compliance with security and life safety regulations.

Installation Requirements

Structural Fixing

• Must be securely fixed into structural substrate (brick, block, concrete, or structural steel)
• Correct anchor type and fixing centres must be used
• Door opening must be structurally sound and square
• No reliance on plasterboard or decorative finishes

For LPS 1175 certified systems, installation must follow the tested fixing specification.

Fixed Mesh or Hinged Security Gates

• Frame must be level and plumb
• Anti-tamper fixings used where required
• Hinges securely anchored and aligned
• Locking mechanism must fully engage
• Perimeter gaps must be minimised to prevent leverage.

Retractable Door Security Grilles

• Top track securely fixed to structural head
• Bottom track (if fitted) accurately aligned
• Trackless systems require precise side guide alignment
• Grille must slide freely without binding
• Locks must engage correctly at closing point
• Operational testing should be completed on handover.

Escape & Fire Route Considerations

If protecting a door that forms part of an escape route:

• Must not obstruct panic hardware (BS EN 1125)
• Must allow immediate internal release where required
• Must not reduce compliant escape width

Life safety must always take priority.

Supply Only Considerations

If supplied without installation:

• Installer assumes responsibility for structural suitability
• Installation must follow manufacturer technical drawings
• Certified systems must follow approved fixing detail

Professional installation is recommended for security-rated systems.

Maintenance Requirements

Maintenance requirements vary depending on system type.

Routine Inspection (Recommended Annually)

Check for:

• Secure fixings
• Frame stability
• Lock engagement
• Signs of corrosion
• Damage or deformation

Higher-use commercial environments may require 6 monthly inspections.

Retractable System Maintenance

• Keep tracks clear of debris
• Lightly lubricate pivot points and locks
• Check smooth operation
