Also in fall-protection glazing and where burglary protection is required.<\/p>\n\n\n<h2 class=\"wp-block-heading\">What does laminated glass mean for the window actuator?<\/h2>\n\n\n<p class=\"wp-block-paragraph\">Like normal glass, laminated glass weighs about 2.5 kg per m\u00b2 and mm of glass thickness; the interlayer adds little. An insulating unit 44.2 VSG-16-4 therefore weighs about 31 kg per m\u00b2. The heavier glass increases the required force, especially on roof windows. Values for common build-ups are shown in the entry <a href=\"\/en\/dictionary\/glasaufbau\/\">Glazing build-up<\/a>.<\/p>\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n\n<h3 class=\"wp-block-heading\">Is laminated glass the same as toughened glass?<\/h3>\n\n\n<p class=\"wp-block-paragraph\">No. Toughened safety glass is thermally tempered and breaks into small crumbs. Laminated glass holds the fragments on the interlayer.<\/p>\n\n\n<h2 class=\"wp-block-heading\">Read more<\/h2>\n\n\n<ul class=\"wp-block-list\"><li><a href=\"\/en\/dictionary\/glasaufbau\/\">Glossary: glazing build-up<\/a><\/li><li><a href=\"\/en\/dictionary\/fluegelgewicht\/\">Glossary: sash weight<\/a><\/li><li><a href=\"\/en\/dictionary\/pitched-roof-window\/\">Glossary: roof window<\/a><\/li><\/ul>\n\n\n<p class=\"wp-block-paragraph\"><strong>See also in the glossary:<\/strong> <a href=\"\/en\/dictionary\/ueberkopfverglasung\/\">Overhead glazing<\/a><\/p>\n\n\n<p class=\"wp-block-paragraph\"><strong>Tools:<\/strong> Calculate force and stroke with the <a href=\"\/en\/window-actuator-calculator\/\">Window actuator calculator<\/a>, find the right model in a few questions with the <a href=\"\/en\/drive-finder\/\">actuator finder<\/a>.<\/p>\n\n\n<p class=\"wp-block-paragraph\">Not sure which actuator fits?
