How to add Colorbond fence extensions?

[caliundro]

G'day.

I'm looking at increasing the height of my current 1500mm colorbond fence to 2100mm for privacy. 

The fence on the other side was knocked down timber and replaced with trim deck colourbond 1800 height + 300mm slattice.

Using the 600mm extension posts is one able to use that, remove the existing 1500 sheeting, install 1800 sheeting, top rail, then add the slattice and another top rail. (As shown of image 2, picture from Google images)

Or, would I need to do as image 1, use of 600mm extensions, add bottom rail, 600mm sheet, add top rail. Done. 

The existing fence is structurally sound and am looking at budget costs and the new landlords is not interested in paying for the fence extension for privacy matters.

On another note we do live in a high wind area. 

Thanks for your help and advice in advance!

Hi @caliundro,

Welcome to the Bunnings Workshop community, it is fantastic to have you with us.

Unfortunately, our suppliers do not produce a 600mm extension post that you can attach Colorbond infill panels to, so you would have to look at something like the matrix fence extensions to achieve the desired 2100mm height.

I would suggest having a look through the following discussion, which explains the installation process -

• How to attach Matrix fence extension to Colorbond fence
   
• Matrix fence extension installation query
   
• How to install a Matrix Decor screen to a Colorbond fence.
   

If you were to use the COLORBOND® Steel 340mm Fencing Post Extensions or source a longer post extension, you could use @ProjectPete's guide on How to add an extension to a Colorbond fence as a reference.

Let me know what you think and if you have further questions, please don't hesitate to ask.
