See below the Kitchen Floor at our CO Mtn. House w/2" x 6" Wall Construction. Didn't deter a Bear coming in and opening the Fridge to snack. This is how we found it; Frozen Berries and Bloody Mary Mix gone:
From the circa-'85 Construction at 9,050' elevation, the Windows are Double Pane + an integral extra Single Pane Storm Window. Bear Forensics, and other breaks-in that Summer [23 total around us], indicated Mama was teaching Junior the fine art of breaking and entering.
4 different Single Pane Windows had been broken out in 'testing' whether they would give to allow entry, and the Clothes Dryer Vent was ripped off the Wall. A huge Bay Window had 2 side Windows that were 2' wide x 5' high. One of those was fully broken out to allow entry. However, the huge triangle of Glass that remained in-Frame meant that Junior got through a space 10" wide w/o drawing Blood. Other than a small 'Barrel' of Fireplace Wood being knocked over, Junior went RIGHT for the Fridge and chowed down. Quite the IQ. An upper Cabinet Door was scratched, due to Maple Sryup inside, we guess.
Nice Antiques were left intact, and there was no Bear 'deposit' left on the Carpet as a 'mark'; something which often happens. Bear Fur on the Window Casing told the story, too.
Some FN IDIOT was putting Bacon Grease in an old Tire in his 'front' Yard to watch the Bears work at getting to it. '2 time Loser' Mama was trapped repeatedly and then killed as per CO Policy. No more break-ins in the several Summers since. This is why the Bumper Sticker says 'Garbage Kills Bears'.
Given the propensity of Bears to chow down and then take a snooze, I was mighty glad to be packing when I went down the Stairs to sweep the finished Basement for resident Bears. It was a Bear- and Poop-free zone.
