Having first correctly measured the window opening before ordering, you will start off with a window that is perfectly sized. 

Then follow these step by step instructions for installing an Ascend Sliding Window into a timber clad construction, by home builder / renovators Kyal & Kara.

What you'll need:

  • Wideline Ascend Sliding Window

  • Window Packers
  • Set of Drills
  • 75mm Screws
  • Safety Gear
  • Estimated time: 1-2 hours 
  • People: 1-2

Tools you'll need to install a sliding window

 

Step 1: Pack Window Sill Until Level

First of all you need to prepare the window opening. It’s important to get the sill straight and level. Start at one end with a 5mm packer and work along the length of the sill until it’s level.

Step 2 : Spread Packers Along Window Sill and Fix Down

Finish off levelling the sill by adding more packers along the length of the sill to help support the window and fix into place.

Step 4 : Unroll Flashing and Position on Outside to Prevent Leaks

Put your window upside down to unroll the black flashing that will sit on the outside of the house and keep any water out.

Step 5 : Install Window Hard Up Against Packed Opening

Install the window so it sits against your levelled sill and hard up against the reveal you’ve plumbed up.

Step 6 : Set Window Reveal for 10mm Gyprock

We have set up the inside of our window reveal for 10mm gyprock. To do this, use a 10mm packer and place it under the frame to make sure it’s flush with your timber reveal. Once you’re sure, you’re ready to fix the window through where you’ve packed it.

Step 7 : Use Packers to Fill Opposite Side and Fix Through

Once you get to the opposite side of your window use your packers again to pack between the reveal and the stud, making sure it’s nice and firm. Fix off through these packers.

Step 8 : Place Packer Under Centre Mullion

Once your window is fully fixed off, place a packer directly underneath the centre mullion for support.

Step 9 : Install Head Flashing

Now that your window is fully installed, it’s essential for the compliant waterproofing of windows and doors in this type of installation to have a hardened head flashing fitted, then you’re ready for some cladding!

The principles are the same when you’re installing this window into a timber frame construction or a brick veneer construction. The main thing that will change is the finishes around the outside.
