The heroal D 72 front door system provides exceptional design versatility in a single system. Performance features of the door system can be matched to the construction project and requirements relating to heat insulation, wind load, air permeability, tightness against driving rain and burglary resistance can be tailored to the conditions on site. For heroal fabricators this means maximum flexibility, an end-to-end system logic and greater production reliability.

• Heat insulation values up to U_f of 1.7 W/m²K
• Comprehensive product range for every application
• Large variety of colours and designs

heroal S 77 SL opens up new large dimensions and guarantees maximum transparency with its unique innovative frame construction. The new generation of heroal lifting-sliding doors combines a movable monorail casement with fixed frame glazing and minimal view widths. This large frameless glazing with clean lines forms an almost invisible link between the inside and outside, extending the living space beyond its actual limits. The heroal S 77 SL lifting-sliding system is a new architectural design element that creates a new sense of space.

The heroal S 77 SL lifting-sliding system creates a harmonised balance between contemporary design, maximum comfort and consistent functionality. Thanks to its elegant and modular construction details, the heroal S 77 SL has unlimited uses in new buildings and renovations.

Additionally, the insulating variant heroal S 77 SL/CC provides for an improved heat insulation due to the optimised design of the central joint, the typical weak point in the insulation of any lifting sliding door. This optimisation creates a comfortable climate in the living spaces.

Versatility is our speciality: heroal S 77 is a modular profile system with a modern design that fulfils the strictest structural requirements. It offers a wide range of profile face widths, is compatible with other heroal systems and comes with an almost unlimited selection of surfaces.

heroal S 77 can also be used to create multi-track design variants and barrier-free systems. Special leaf profile shapes ensure that all sizes and weights of leaf meet the applicable requirements and regulations for heat insulation. The heroal seal technology with three levels and sealed corners – for leaf and central joint sealing – ensures optimum air permeability and tightness against driving rain.

Through the smart combination of selected materials and geometries, the heroal W 77 window system achieves U_w values up to passive house suitability with a design depth of only 77 mm. Sash profiles are available with push rod fitting grooves (SBN) and plastic fitting grooves (KBN), which makes a flexible fabrication possible. Windows with a high proportion of glass can be created thanks to the minimum face width of just 90 mm. The standard window system heroal W 77 with a face width of 120 mm achieves a U_f value of 1.1 W/m²K, and can be further enhanced or extended. Extensions are heroal W 77 HI (Highly Insulated - enhancement of the U value through the use of different sealings and insulations; U_f value of 0,95 W/m²K), heroal W 77 PH (Passive House - U-value at passive house level with a face width of 180 mm; U_f value of 0,78 W/m²K) and heroal W 77 UD (Universal Design - French doors with a threshold height < 20 mm). heroal W 77 also allows for the simple implementation of façades for stairwells.

• High thermal insulation with low design depth
• Proven performance features, combined with heroal WF and heroal WF EM fittings
• Great variety of colours and designs

Available as a heroal plus package.
