When you choose SheerGuard, you can be sure that you will get a product that will last as long as your home does — and one that will look good while it does it!

  • Are Primate Barriers made from plastic or perspex?

    It is neither of those; our SheerGuard Primate Barriers are manufactured from a thermoplastic polymer called EXOLON® the highest quality Polycarbonate and strongest material available today.

  • Can Primate Barriers be broken?

    Eventually someone could break them with the right tools, lots of noise and repeated efforts. EXOLON® the highest quality Polycarbonate has an extremely high impact resistance and a tensile strength of over 3 tons which makes it tougher than steel! Because of its strength and shatterproof properties Polycarbonate is used in high demand applications such as bullet proof windows, police riot shields, jet-fighter cockpits etc.

  • Primate Barriers stronger than Steel Burglar Bars?

    There are a number of variables to consider when comparing Steel to Primate Barriers – one is how they are fixed to the frame. Most Steel Burglar Bars are welded to the frames which is not strong enough as all it takes is a simple twist of the bar with a spanner and the weld will break.

    SheerGuard Primate Barriers are secured with stainless-steel, tamper-proof compression rivets to the frame which are much stronger and twice the weight of your standard rivet, with a domed head that can not be drilled out.

  • Do Primate Barriers corrode or deteriorate over time?

    Unlike Steel Bars, SheerGuard Primate Barriers are maintenance-free and DO NOT rust or corrode when exposed to moisture or solvents and are coated with a special UV protection which guarantees the bar against the loss of clarity for up to 10 years.

  • Could a fire burn through Primate Barriers?

    Polycarbonate has an inherent flame retardant and is heat resistant, unlike plastic it does not ignite and drip flaming liquid, it actually extinguishes itself as it is being burnt. This is not to say that they cannot be burnt through them but if someone does try to burn through them, it would take a few minutes to get through our bars and a lot of smoke and smell is produced.

  • Is it expensive?

    No, SheerGuard Primate Barriers compare favourably to custom fitted Steel Burglar Bars and in most cases work out to be more economical.
