Today, the importance of energy conservation and efficient energy use is growing alongside the significance of energy sources themselves. In building complexes, 82% of energy consumption is dedicated to heating; this figure accounts for 26% of the total energy used in our country. Heat loss in buildings stems from various sources: 40% through exterior walls, 30% through windows, 17% through exterior or balcony doors, 7% through the roof, and 6% through the flooring. Consequently, residential buildings—and specifically PVC window systems as a form of insulation—emerge as key areas for achieving energy savings. The fact that energy is the most limited and costly resource places greater emphasis on “energy conservation”—or insulation—within window systems.
The Storline system is supported by various components:
Insulation foam
Openable side cover
Intermediate rail profile
Side rail profile
Shutter panels
End profile
These components ensure the sliding system operates in a balanced manner regarding both statics and performance.
High Insulation & Energy Efficiency
With an 82 mm depth and high-quality profile, heat loss is significantly reduced.
Strength & Durability
Offers long-lasting performance with C3 wind load resistance and a robust profile structure.
Comfort & Noise Insulation
Reduces external noise levels with 40 dB sound insulation.
Project Compatibility & Flexibility
Its ability to accommodate various glass thicknesses allows for a wide range of applications in architectural projects.
The limited nature of energy resources has made efficient energy use in building systems a priority. In line with this, Erpen developed the Storline system to reduce heat loss in window and sliding systems. Insulated systems are of great importance, as a significant portion of heat loss in buildings occurs through windows and glass surfaces.
Storline is backed by quality certificates and test reports confirming its production in accordance with TS-5358 / EN 12608 standards. All documents and reports related to the product can be downloaded in PDF format from our website.
