MPH DUAL is a pleated insect screen system, which belong to the HARMONY family. The system has been designed as a two-wing variant with the possibility of making a corner insect screen without a post. Due to this solution, the product can be used on standard terrace doors, whose dimensions reach up to 6m wide and 2.7m high, as well as on increasingly popular HS type corner sliding doors. A characteristic feature of the MPH DUAL system is a pleated mesh which, when closed, forms a harmonica and then hides in the side profile and due to this solution allows for optimal use of space. The mesh is available in several sizes, so called sets, which depending on the needs can be cut, thus adjusting the mesh to the size of the joinery. Moreover, the mesh is available in two colours: grey and black, which allows to adjust it to the needs of the user. The MPH DUAL system is characterized by an extremely smooth movement, which makes its use very simple and does nor require much effort. Two sizes of sliding profiles are available in the offer. In addition, the construction of the insect screen allows to stop it in any position. The advantage of this solution is also the low threshold, which facilitates smooth passage. The construction of the insect screen is made of extruded aluminium, which makes it durable and resistant to weather conditions, and in addition it can be varnished in any colour. The pleated insect screen MPH DUAL works with roller shutter systems and lift and slide balcony doors MB-77HS available in Aluprof’s offer.
