Internal glass window guards are fitted typically on the upper floors of houses and apartments, internally between the window reveal to the outmost external edge of the sill. They are inserted to prevent accidental falls through externally glazed windows or Lites . The external glazed panels and IGU’s are safe and fit for purpose. However, they are not designed to prevent loadings associated with forces or falls at a height below 1100mm . To keep your home, new build or rental property safe from such hazards, NSG supply and fit window guards that are suited to many different configurations. We have consulted on the retrofitting of glass window guards on new builds and public rented accommodation to bring those buildings up to code.

At NSG, we specialise in the supply and installation of internal glass window guards—a discreet and elegant solution designed to prevent accidental falls from upper-floor windows in homes, apartments, and public buildings.

Many homes and apartments have externally glazed windows that aren’t designed to withstand impact forces below 1100mm. This poses a serious safety risk—especially in upper-floor rooms, children’s bedrooms, or rental properties.

Building regulations require protective measures in certain scenarios, and internal glass guards are a simple, elegant solution.
