Security (metal) exterior doors are intended for flats only as they do not have thermal break. Aluminium and PVC exterior doors are intended for both houses and flats, and can be supplied in any colour according to RAL colour chart (ALU) or in several imitation wood options. Locks can be either short regular (or intercom locks) or prolonged three-point or five-point locks. Doors are supplied as single-wing, double-wing or triple-wing ones, and with a variety of options in terms of transom windows and fixed fields. We supply them with door handles or grips of different size and length, and we offer installation of self-closing door mechanisms. ALU and PVC doors differ in their thermal features, type of material, colour, price, and potential for manufacturing large-size doors which is characteristic for aluminium profiles.
