How to Install Clear Guard

Clear Guard is designed for straightforward DIY installation using basic tools. Follow the steps below to install your transparent window security system securely and achieve a clean, professional finish.


Tools Required

  • Battery drill
  • 5mm drill bit
  • Hand or battery-operated riveter
  • Screwdriver or suitable driver bit (No. 2 square drive if using square-drive screws)
  • Suitable screws and anchors for your installation surface
How to Install Clear Guard tools

Important: Mounting screws and anchors are not supplied, as the required fixings depend on whether you are installing into timber, masonry, concrete or another suitable surface. Other standard installation components are supplied with the kit.

Recommended Fixings are:

Wood Fixing:
Use 8-gauge screws (28–40mm, or up to 100mm for deep penetration through multiple wall layers). Screws pass through the 10mm access hole and fasten into the 5mm fixing hole.

Concrete Fixing:
Drill a 5mm hole into the concrete, insert a wall plug, then use 8-gauge screws.
For applications that need extra strength, use a 10-gauge hex head screw.
The holes should be drilled 16 mm / 7 mm into the material.

 

Step 1: Prepare the Installation Area

  • Check that the window opening matches your Clear Guard dimensions.
  • Ensure the installation surface is clean, solid and free from obstructions.
  • Unpack all components and identify the left and right side frames.

Step 2: Position and Install the First Side Frame

  1. Position the first side frame at your preferred location within the window opening. 

    The larger access holes on the side frames must face inward, towards the inside of the premises. The smaller fixing holes should face the mounting surface.

  2. Ensure the frame is straight and correctly aligned.
  3. Check that the rivet holes face inward and remain accessible for installation.
  4. Secure the top fixing screw first.
  5. Once aligned, install the remaining fixing screws.
  6. Insert the supplied fixing caps to cover the screw holes.

Tip: The side frames can be positioned towards the front, middle or back of the window opening. Make sure there is enough clearance to access all rivet points with your riveter.

Step 3: Prepare the Polycarbonate Slats

  1. Identify the protective film covering each slat.
  2. Carefully peel back approximately 50mm of film from both ends of each slat.
  3. Leave the remaining protective film in place to prevent scratches during installation.

Important: Removing the film from the ends before fitting makes it easier to expose the complete surface after the slats are secured.

Step 4: Install the Slats and Opposite Side Frame

  1. Slide each polycarbonate slat into the installed side frame.
  2. Guide the opposite ends of the slats into the second side frame.
  3. Ensure all slats are correctly seated and evenly positioned.
  4. Align the second side frame with the first.
  5. Check that both frames are parallel and straight.
  6. Secure the second side frame using suitable fixing screws.
  7. Install the supplied fixing caps.

Check that the slats are properly seated before permanently securing the opposite frame.

Step 5: Install the Centre Support (If Supplied)

For wider openings, a centre support may be included to provide additional stability.

  1. Identify the centre support and its top and bottom fixing brackets.
  2. Slide the bottom fixing bracket into the support's lower groove.
  3. Attach or position the top fixing bracket.
  4. Position the support at the centre of the window opening.
  5. Ensure the support is straight and correctly aligned with the slats.
  6. Secure the bottom bracket through its fixing holes.
  7. Secure the top bracket in the same manner.

Note: The bottom of the centre support has additional clearance to accommodate its fixing bracket. Check the bracket orientation before installation.

Step 6: Secure the Slats

  • Check that each slat is correctly positioned.
  • Ensure the rivet fixing points are accessible.
  • Secure the slats at the designated fixing points using the supplied rivets and a hand or battery-operated riveter.
  • Use the 5mm drill bit where drilling is required, following the positions demonstrated in the installation video.
  • Check that all connections are secure.

Avoid overtightening or forcing components against the polycarbonate.

Step 7: Remove the Protective Film and Clean

  1. Carefully peel away the remaining protective film from all polycarbonate slats.
  2. Remove any installation dust and debris.
  3. Wipe the slats gently with a clean, soft, non-abrasive cloth.
  4. Remove surface static and dust to restore maximum clarity.

Avoid abrasive cleaning materials that could scratch the polycarbonate.

Final Installation Check

Before finishing, confirm that:

  • Both side frames are securely fixed.
  • All polycarbonate slats are correctly seated.
  • All required rivets are securely installed.
  • The centre support is properly fixed, if supplied.
  • All screw-hole caps are fitted.
  • All protective film has been removed.
  • The transparent surfaces are clean and free from installation debris.

Your Clear Guard installation is now complete, providing an additional physical security barrier while preserving visibility and natural light.

Why Some Homeowners Choose Clear Guard

Traditional window bars create a strong visible deterrent, but they may not suit every home or personal preference.
Some homeowners prefer a cleaner appearance that maintains visibility, natural light, and the overall feel of their living spaces.
Clear Guard provides an alternative approach.
Using strong polycarbonate slats within an aluminium frame, Clear Guard helps strengthen vulnerable windows while keeping views open and maintaining a lighter, less intrusive appearance.
It is commonly chosen for:

  • Modern homes
  • Living rooms and street-facing windows
  • Areas where preserving natural light matters
  • Homeowners wanting protection with a more subtle appearance
  • Properties where traditional bars may feel visually heavy

Clear Guard offers practical window protection without creating the enclosed appearance that some people associate with traditional security bars.
