Site Procedure 1: Installation of Sub-frame

The galvanized steel sub-frame, origin from Italy, is cast in or anchored onto the wall structure, in order to create a more precise opening for the main frame to be subsequently mounted when all other trades have completed their works.

Site Procedure 2: Main Frame Installation

The main frame is mounted to the sub-frame when the site is ready. 

  • Adjustable spacers are used to maintain the alignment of the outer frame. 
  • Stainless steel screws or Hilti wall-plugs are used to mount the main frame to the sub-frame or wall structure.
  • Hilti insulating foam is used to fill up any gap between main frame and wall.
  • Bostik sealant is used to seal the edge of main frame and wall structure, usually in white colour.
  • All our Aluminium frames are well protected from scratches or potential damage.

Site Procedure 3A: Glazing Work and Protection

  • Setting blocks are used to prevent glass from directly touching the aluminium frames
  • Dow Corning silicone is used to seal up the gap between glass and aluminium frames
  • PE sheet is used to protect the glass before final cleaning

Enhancing The Beauty, Security And Durability of Your Dream Home

Site Procedure 1: Sub-frame Stage

Installation of Sub-frame
– Sub-frame is cut into size on site
– Corner joint is used for ensuring the perpendicularity of sub-frame
– Galvanized strip and Hilti products are used to fix the sub-frame to the wall structure
Advantages of Sub-frame system
– Generally has better water tightness performance
– Can be used for precast or cast in-situ wall systems which do not require plastering
– Allow greater flexibility in the sequencing of works of other trades; the sub-frame is installed first so that the wet trades around the window can be completed before subsequent installation of the main frame
– The main frame are installed after completion of all wet trades around the windows and hence, are subjected to lower risk of physical damages
