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)

The Windowsystem
Innovative, flexible, practical
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

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
