INDU LIGHT Energy-Line-Silent technology is benchmark for the industry.

ELS energy saving potential is still unrivalled in the market.

Exceptional thermal insulation with advanced ELS technology

With Topline ELS, INDU LIGHT presents the benchmark in continuous rooflight technology. ELS combines outstanding thermal insulation, excellent soundproof values and various options of integrated shading systems.

Cost savings are achieved by the high thermal insulation of ELS when heating your building. Utilizing natural daylight additionally reduces power consumption of electrical lighting.

ELS sunbloc can be integrated and provide the shading functionality which will maximize energy saving when cooling is required.


First-class thermal transmission value (U value) according DIN standard

Topline ELS achieves the overall U value of up to 0.9W/m2k. The overall U values refer to the transmission values calculated for the entire construction. Determined by an independent authority the calculation basis considers an 80mm frame insulation and is valid for horizontal installations. Values indicated are standard values and meet current technological standards. 

Individual values may vary – please contact your INDU LIGHT representative. General technical approvals by the Institute of Building Technology are available.

Topline ELS can be used in all climate zones. UV characteristics are adapted regionally. 

Environmentally soundproofing values

The high sound reduction index of the ELS system (max. 33dB) satisfies the stringent soundproofing requirements of national law. The legislation defines maximum levels for the impact of sound on the environment and is intended to protect the population. For planners and building owners ELS can improve the planning security in the construction permit application process. With minimum sound impact on the environment ELS also offers a higher flexibility in the choice of where to locate your new plant.

 

ELS sunbloc – sunblinds, glare shield and climate control

Topline ELS offers integrated sunblinds for optimized climate and shade control.

Installed between the multiwall polycarbonate sheets ELS sunbloc is not affected by fast changing weather conditions and ventilation functionalities can operate independent from the shading system.

Fall-through protection and durability

Secure fall-through protection – maximum safety with minimal visual impact.
Steel mesh grids can be added and with minor design modifications Topline ELS complies with the requirements of ETAG 010, DIN EN 14963, DIN 4426 as well as GS-Bau-18 and the Swiss SUVA standard.

Durability of materials – According to the local conditions the intensity of solar radiation varies quite substantially. As a consequence the UV resistance of the materials need to be adapted accordingly.
Based on the solar zone map, we define the  multiwall polycarbonate sheets which exactly fit to the prevailing UV radiation levels. This enables us to guarantee quality and durability of our products.

Fall-through protection

Safety is our number one priority. That is why all INDU LIGHT continuous rooflights come together with the IAP1 anchor point. This includes a stainless steel bracket which is integrated in the eave structure of the continuous rooflight and fixed to the frame head. Attached to the PPE it protects personnel from falls. Anchor point IAP1 is a tested class A1 anchor device in accordance with EN 795:1996-07/A1:2000-10 (D) und EN 795:2012-10 (D)

RAL coating

On request, all aluminium profiles can be supplied in RAL colours, according DB colour chart, or other commonly used systems. Available coating types are sustainable standard powder coating,  seawater-proof coating or anodizing.
