LAMINATED GLASS LAMINATES HAVING HEAT-RADIATION-SHIELDING PROPERTIES BASED ON THIN FILMS FORMED FROM UNPLASTICISED POLYVINYL ACETAL

摘要

A heat-shielding laminated glass laminate, consisting of at least one film A containing a polyvinyl acetal PA and optionally at least one plasticiser WA and at least one film B containing a polyvinyl acetal PB and at least one plasticiser WB between two glass sheets, characterised in that in each case prior to lamination - a proportion of plasticiser WA of less than 16 % by weight is dispersed in film A, - a proportion of plasticiser WB of at least 16 % by weight is dispersed in film B, and - heat-shielding particles are dispersed in film A.
