Lambda –
The Windowsystem innovative, flexible, practical
Total new design addressing the requirements of the European markets

Project „New window series“
1976 German parliament decided upon
Energy Conservation Act
1978 Introduction of a regulation upon energy-saving heat insulation
(Heat Insulation Ordinance)
1984-95 Amendment of the
Heat Insulation Ordinance
2002 Heat Insulation Ordinance was displaced by the Energy Saving
Regulation (EnEV) (1 Feb 2002)
2007 Regulation upon energy-saving heat insulation and energy-saving installation (1 Oct 2007)
2008 Energy Performance Certificate (for buildings) becomes obligatory stepby-step (1 July 2008)

Processing
Simple processing
 Connection: crimp, punch, drill
 Stable inner chamber
 Optimized connections
 Improved ability of turning
 Coatable compound profiles
 Easy change of series

Processing
 Cutting tolerances +/- 1,5 mm
 Improved ability of turning, small sashes, down to 350 mm
 Slotted, self-leveling corner cleats: automatic leveling in height for a neat flush mitre, with minimal adjustment required (driving pin/nail home automatically levels profiles)

Processing
 Easy to apply T-connectors with integrated gasket
 Identical hole pattern for corner und T-connectors
 All processing for corner and T-connections can be done by different punching tools as stationary punches, handpunches, multipurpose punches as well as drilling jigs
 Reduce number of crimping knives required for the crimping of the frame profiles –> less change in tooling when using different frame geometries
 Upgrade kits for several 1.0 punching tools reduce the necessary invest for fabricators who used 1.0
 Delivery of mill-finished compound profiles and surface treatment done by the customers possible
 Processing tools: stationary punches, hand punches, multipurpose punches and drilling jigs available

Software
 Training of diverse software houses has been executed and an update of their software including lambda will be possibly available contemporary:
 ORGADATA
 C-Mol
 SYSCAD
 MAP
 FEBOS

U-values
 Insert strips provide minimum
U-values with comparable small insulating area
 Competitive U-values with small insulating area give advantages in stability compared to competitor designs
 Insert strips allow flexible reaction of the customer on differing value requirements
