Beading strips are used to secure the double-glazed or triple-glazed unit.
When the beading strips are situated internally, this means that the glass unit is secured in place from inside the room. The glass simply cannot be removed from the outside without breaking it. Windows supplied and fitted by Admiral Windows Oxford are internally beaded as standard.
Externally glazed windows have their beading strips situated on the outside face. For security, modern externally glazed windows have wedge gaskets that must first be removed from inside before the beading strips can be withdrawn.
