During an initial site survey, AIANO engineers will take accurate measurements and photographs of the windows to be guarded. We will also, where appropriate, take templates of the exact window shape where necessary and note in special features of the windows or the installation that need to be taken into consideration.

AIANO engineers can then make a second site visit to install your window guards and grills. We will always seek to use the most appropriate method of fixing for each project taking into account security, any constraints in the fabric of the building, and cosmetic or aesthetic considerations.
