Grille guards are unobtrusive, blending in well with the fabric of historic buildings. They offer protection against large projectiles such as stones and are an effective deterrent against break-ins.
The guards are manufactured from stainless steel mesh finished in semi black high temperature powder coat paint. They are fixed using discreet brackets and screws, all non ferrous.
Each guard is accurately profiled to the aperture of each window and fitted approximately 25mm in front of the stained glass.
This method is an excellent deterrent to attempted break-ins. It offers protection against projectiles such as stones and also resists damage from pellet guns etc. Polycarbonate also acts as double glazing, reducing noise, draughts and shielding the stained glass from wind pressure.
The polycarbonate and stainless steel fixings are unobtrusive from the outside and invisible from the inside, allowing the glass to be viewed clearly.
The existing glass is thoroughly cleaned before protection.
We use Makrolon Longlife Clear 2099 polycarbonate (8mm for extra rigidity). It is fire resistant and U/V stabilized on both sides guaranteeing its optical clarity for 10 years.
All fixings and materials are maintenance free and compatible with the fabric of the building. Air flow is maintained to prevent condensation.
We have been granted zero VAT rating on protection to listed building
