EPAL Slim

Refined appearance and robust protection.

Profiles for opening-tilting aluminum windows

The Slim series of aluminum frames stands out for its refined and understated design, featuring thin profiles and concealed hinges that offer unmatched flexibility in the design and decoration of a space.

Top Moisture Sealing

According to EPAL’s high standards, the frames of this series offer a thermal transmittance coefficient (Uw) starting from 0.87 W/m²K, thanks to the longitudinal polyamide thermal break and double thermal insulating glazing. The superior sealing from moisture and air is ensured with two perimeter-applied EPDM seals. An additional advantage of the series is the multi-point locking system that provides a high level of security.

High Functionality - Subtle Design

The uniquely designed tilt-and-turn windows owe their aesthetic superiority to the clean construction lines and the German-made hidden Roto NT Designo opening mechanism, which combines high functionality with subtle design.

The frames in the Slim series follow the principles of minimal aesthetics for comfortable spaces that impress. They can be combined with screens and shutters.

Product Description

The EPAL SLIM series is a thermally-insulated window with an elegant design, stability, and ease of production, making it one of the best solutions for new constructions as well as the replacement of old windows.

Respecting the original design, it offers a significant improvement in thermal insulation.

It provides an unmatched design thanks to the use of the NT Designo mechanism by Roto-Frank, with hidden hinges, ensuring that nothing undermines the appearance of the window.

Technical Characteristics

The windows of the EPAL Slim series have the following characteristics:

  • Profiles with polyamide thermal break of 32mm throughout the length of the profile.
  • Openable – tilt & turn windows.
  • Equipped with Roto NT Designo mechanisms from Roto-Frank with hidden hinges for superior aesthetics and design.
  • Pressed corners.
  • Perimeter applied EPDM gaskets for perfect sealing.
  • Multi-point locking system designed to work flawlessly and effortlessly while maintaining style and durability.
  • Made from specific materials and components that meet high-quality standards.
  • Supplied with insect screens or blinds.
  • Manufactured under controlled production processes that ensure consistent and high quality.

Advantages

The EPAL Slim window series ensures:

  • Very high thermal insulation. The EPAL Slim system allows the construction of windows with excellent thermal insulation properties (up to Uw = 0.87 W/m2K).
  • High levels of sound insulation: Rw (C; Ctr) = 38 (-2; -6) dB weighted sound reduction index (with triple glazing 6Planistar – 15 – 4 – 15 – 4).
  • High resistance to mechanical stress during use and excellent functionality.
  • Superior aesthetics with a wide range of colors and high-quality electrostatic painting.
  • These projecting windows rotate outward for easy cleaning from the inside, maximum ventilation, and almost effortless operation.
  • Installation of EPAL windows is performed by specialized technicians on any surface using special components and insulating materials, ensuring a perfect fit.

Glazing

EPAL imports glass panels from the largest glass manufacturing companies in the world.
