I've installed a Perspex (Acrylic) panel on the interior of the front door of the cottage. Its purpose is to protect the existing door glazing from the rare, but careless/negligent, actions of guests. A couple of weeks ago, a guest managed to put his fist through one of the panes and scattered glass across the road outside the house. This is despite there being an inner door to protect the outer door. It's an old door with nine original, but obsolete privacy patterned annealed glass panes covering the upper half.
The acrylic plastic is colourless clear cast and is 6mm thick. It is almost impossible break without tools. I've milled out a solid oak frame, with mitre joints at the corners to hold the acrylic panel in place. The panel covers all of the interior side of the glass. I robustly mounted the panel on Friday morning in time for the arrival of the latest guests in the afternoon.
Unfortunately, the replacement pane of toughened and patterned glass for the front door is not yet available. It is on special order via a specialist glazier and their supplier has encountered some production problems. So sadly, I've had to tell our new guests, while the front door is now secure there is still an unsightly temporary plastic sheet covering the missing pane. I've had some wooden beading bespoke manufactured to the correct (imperial) dimensions by a local company. The beading will be used to secure the pane when it arrives. The beading is a good match for the old beading which has received some damage. Despite many phone calls, I've not been able to track down a supplier who retails this obsolete wood moulding off the shelf.
I'll be holding discussions as to who pays for remediation of the damage!
