Aluplast Lift And Slide uPVC Doors.

An ideal solution for those who want a comfortable combination of the interior and terrace and the panoramic view achieved thanks to a large glazed area is the use of the lift and slide doors. Special fittings mechanisms allow you to move huge wings using minimum force. Turning the big handle down, from the closed position, raises the wing by a few millimeters, releasing the pressure of the gaskets and the enabling you to move the wings freely.

An unquestionable advantage of this type of patio doors are the possible dimensions of its construction. The width of the wing can be from 0.8 m to 3 m wide and up to 2.7 m high in white color, which allows you to create even a more than six-meter glazing.

Changes in the construction of sections have allowed for a significant improvement in thermal permeability of profiles, which depending on the chosen option allows to obtain an average value of the heat transfer coefficient Uf = from 1.5 W (m2 * K) in the Basic version, through Uf = 1.3 W (m2 * K) in the Standard version up to Uf = 1.1 W (m2 * K) in the Premium version. Despite their huge size, Lift slide doors remain an effective barrier against the escape of heat.

The table below presents the values of Uw heat transfer coefficient for example Lift slide doors (SCHEMA A) with dimensions 4000 x 2300 mm glazed with double-chamber glass with a heat transfer coefficient for the middle part of the pane Ug = 0,5 W (m2 * K) and Ug = 0,7 W (m2 * K) and the values of linear heat transfer coefficient of thermal bridge at the interface between the pane and the frame Ψ = 0,04 W (m2 * K).
System is available in white, brown, cream and anthracite core.
