  • All INVISI-GARD hinged doors are fitted with three point locks & three hinges for added security.

  • Incorporating the unique patented EGP Retention System, your doors can be ordered as a Standard Door with or without a mid-rail. 316 Marine Grade Stainless Steel Mesh is used in all INVISI-GARD Stainless Steel Security Products and it is because of this 316 Marine Grade Stainless Steel that Invisi-gard out performs all other stainless steel security products when it comes to corrosion resistance.

Alpine Glass were prompt, took time to answer our questions and gave us a options in fittings. When they installed the shower screen it fitted perfectly and we are very happy with our design options. It’s refreshing to have tradies that are good communicators.
