Maximising Fitment

Maximising Fitment

If you would like to ensure that your  ViewProtect Transparent Burglar Bars are fitted as securely as possible, take a look at some of our tips below.

Read these tips in conjunction with the installation procedures which may be found in the packaging of the product.

IMPORTANT! Always remember that the point of installation is potentially where a weakness can occur that might be exploited further by intruders.

  • Holes should not be closer than 9mm from any edge of a 6mm polycarbonate strip.
  • The polycarbonate strips must be installed as securely as possible if you wish to obtain the maximum strength.
  • The diameter of the hole, through the polycarbonate strip, must always be 1mm larger than the diameter of the screw or pop rivet being used.
  • When the polycarbonate strip is being installed in the inside of the window frame using a 4.8mm pop rivet make use of a metal washer (M5) with a 4.9mm hole when pop rivet is installed from the outside of the window frame. The holes in the polycarbonate strip require a metal washer to prevent the pop rivet to be pulled through the polycarbonate strip.

It is recommended that you drill the hole in the aluminium tubing +/- 5mm from the edge (closest to the window) of the tube. This will allow your polycarbonate strip and the fitment hole to be the required 9mm from the edge.

Only drill holes in hardwood window frames to prevent the wooden frame from splitting when screws are installed.

  1. Drill 6mm hole on both sides of the polycarbonate strip.
  2. Remvoe membrane partially on both sides of strip.
  3. Install the first screw at a slight angle away from the middle of the window.
  4. Install the second screw at a slight angle away from the middle of the window.

Maximum fitment strength on wooden frames:

  1. Use large screws with a large thread instead of one way screws. The larger thread may provide you wiht a better fitment in the wooden frame. After installing these screws, use a steel drill bit and drill out the screw slot to prevent tampering by an intruder.
  2. For the ultimate fitment strength, install the tubing in the reveal of the window.

 

 

Aluminium/Steel Installation

  1. Drill a 6mm hole on both sides of the polycarbonate strip.
  2. Remove membrane partially on both sides of strip.
  3. After marking out the strip position on the window frame. Drill on one side only. Drill a 5 mm hole in the aluminium/steel frame for the pop rivet. If self-tapper screws were used, a 4mm hole must be drilled.
  4. Place the one hole in the polycarbonate strip over the hole in the aluminium or steel frame and install the polycarbonate strip by pop rivet or self-taper screw.
  5. Take the loose end of the semi installed polycarbonate strip and place it over the opposing side of the window frame.
  6. Use a 3.5mm drill bit and place it through the polycarbonate hole to the side and mark the off centre position for the hole in the frame.
  7. Drill a 5mm hole in the frame for the pop rivet.
  8. When placing the pop rivet or self-taper in the semi installed polycarbonate strip, you will have to apply some pressure to insert it in the frame, this will ensure a solid and firm installation.
  9. Repeat 6-8 for each strip before moving to the next strip.
  10. Install top, then bottom, then second from top, then second from bottom, etc.

Cross Polycarbonate Strip Installation

Additional information regarding the polycarbonate strips to consider when installing your bars.

read more...

When installing polycarbonate strips longer than 1 meter we recommend that the polycarbonate strips must be fixed to a cross polycarbonate strip every 700mm apart. This is primarily dependant on how firmly the installer is able to install the polycarbonate strips and whether or not the window frame is loosely installed in the brickwork. These cross sections must also be fitted to the frame surrounding the window.

How to install cross polycarbonate strips:

 

  1. Drill a 6mm hole through both the polycarbonate strips at the crossing.
  2. Insert the pop rivet from the outside through both of the polycarbonate strips.
  3. Place a plastic washer in the inside for the cap, onto the polycarbonate strip AND A METAL WASHER WITH A 4.9mm HOLE (M5) between the strips and inside on top of the plastic washer.
  4. Use a pop rivet gun to install the pop rivet and make sure that the pop rivet has a clearance of at least 5mm past the metal washer before pulling.
  5. Place a black (dark) cap over the plastic washer on the inside for a clean and neat look.

Additional polycarbonate strips over fitment

Additional information regarding the polycarbonate strips to maximise your fitment.

When installing the polycarbonate strips to timber, aluminium or steel windows, you can use an additional polycarbonate strip and install them across the polycarbonate strips fitted to the frame. This will mean that all the polycarbonate strips are connected to each other and ensure that the installation is more secure.
