LUMEAL GA
2 Leaf Patio Door Minimalist Horizontal Slider
LUMEAL is a concealed-opening slider offering minimalist lines and only 68 and 77mm aluminium visible, around 35 % less visible structure. This slim design gives 8 to 14 % more glazed area according to the applications, as well as a Sw of 0.48.
LUMEAL concealed opening sash is a new concept totally different from the traditional sliding window to create new sash / frame combinations . It is therefore possible to produce asymmetrical 1-leaf + fixed frames, with a large section fixed and an opening section the size of a door without increasing the amount of visible aluminium. LUMEAL is designed to manufacture large sliding systems, up to L 4.50m x H 2.70m with 2 or 3 rails and up to 250kg per leaf.
LUMEAL patio-door threshold allows an easier access, conform to European standards and maintaining the sealing performance.
Locking mechanisms:
The locking system integrated in the fixed frame is not accessible from the exterior in order to improve security. Three exclusive-design handles which discretely merge into the visual perception of the sliding sashes.
Performance:
LUMEAL exceptional performances are equivalent to a casement frame:
Thermal performances: Uw = 1,4 W/m².K for a 2 leaves patio-door
Air – Water – Wind performances : A4-E5A-VB3
Conformity with the air permeability criteria for BBC labelling buildings
Using concealed opening technology, LUMEAL boasts an acoustic performance that far exceeds that of conventional-design sliding windows:
Up to 37dB (Ra, Tr) for a 1-leaf patio door + 1 fixed frame
Motorization:
The LUMEAL product range proposes a motorized option to answer to accessibility and design customers’ requirements. Fully integrated to the slider, LUMEAL with motorized option saves its same high performance and aesthetic.
User comfort and security:
Large dimensions (frames up to 4 meter long)
Easy and noiseless lateral displacement (speed around 0.15m/s)
In case of obstacle, the door stops and goes back to release
Possibility of manual handling in case of power cut
