These windows are characterized by minimal energy input from secondary heat radiation and enable the lowest g-values.

doubled fa\u00e7ade are an extremely energy-saving support for the air conditioning of buildings, as only the minimum air volume of the fa\u00e7ade cavity is tempered without the external heat load reaching the interior. Using the retrojalousia, even negative g values are possible depending on the air temperature supplied, as the absorption at the louvre mirrors is &lt; 5%. With the support of the cold air supply, the inner pane can even become a cooling surface for the interior.<\/div><\/div><div class=\"x-col e723-e73 mk3-2j\"><div class=\"x-text x-text-headline e723-e74 mk3-2l mk3-2m mk3-2q mk3-2r mk3-2s mk3-2u mk3-2v\"><div class=\"x-text-content\"><div class=\"x-text-content-text\"><span class=\"x-text-content-text-primary\">Venetian blind cavity for RETROLux 20 \/ 25 mm slats<\/span>\n<\/div><\/div><\/div><span class=\"x-image e723-e75 mk3-3z mk3-40 mk3-42 mk3-43 mk3-45\"><img decoding=\"async\" src=\"https:\/\/www.retrosolar.de\/wp-content\/uploads\/2025\/07\/Cross_Section-detail.webp\" width=\"725\" height=\"755\" alt=\"Image\" loading=\"lazy\"><\/span><div class=\"x-text x-content e723-e76 mk3-2y mk3-30 mk3-31 mk3-32 mk3-34 mk3-35 mk3-36 mk3-37 mk3-3m mk3-3n mk3-3p\"><p>The key design feature is the patented, simple and quick installation of an inner pane. The secret is anchoring the inner pane by means of a locking rail 100, which slides over the upper front edge of the inner pane 101 and hooks into a hook profile 102 of a tambour door head rail 103. The pane sits at the bottom in a U-shaped seal on the frame profile. A U-shaped rubber profile is also used on the longitudinal edges, which is pushed laterally against the mullions and seals the cavity 105. Warm, humid air is expelled upwards when the sun enters.<\/p>\n<p>Either the RETROLux venetian blind with a width of 25mm or 75mm is recommended as a sun and glare protection measure. The working and shading functions of these blinds are carried out in a horizontal slat position and simultaneously allow daylight to enter inwards and a view outwards.<\/p><\/div><\/div><div class=\"x-col e723-e77 mk3-2j\"><div class=\"x-text x-text-headline e723-e78 mk3-2l mk3-2m mk3-2q mk3-2r mk3-2s mk3-2u mk3-2v\"><div class=\"x-text-content\"><div class=\"x-text-content-text\"><span class=\"x-text-content-text-primary\">Venetian blind cavity for RETROLux <br \/>75 mm slats<\/span>\n<\/div><\/div><\/div><span class=\"x-image e723-e79 mk3-3z mk3-40 mk3-42 mk3-43 mk3-45\"><img decoding=\"async\" src=\"https:\/\/www.retrosolar.de\/wp-content\/uploads\/2025\/07\/Jalousiekavitaet_75mm.webp\" width=\"600\" height=\"704\" alt=\"Image\" loading=\"lazy\"><\/span><div class=\"x-text x-content e723-e80 mk3-2y mk3-30 mk3-31 mk3-32 mk3-34 mk3-35 mk3-36 mk3-37 mk3-3m mk3-3n mk3-3p\"><p>A U-profile (2) is fitted over the inner glazing (1), which sits on an angled rail (4) and forms a largely closed cavity (5).<\/p>\n<p>The angle rail (4) is firmly connected to the blind head rail (6) in which the 230 V motor (7) and the winding mechanism of the blind (8) are installed. This results in an open channel (9) in the shadow gap, into which the motor cable (10) and the Hirschmann plug\u00a0 can be inserted.<\/p>\n<p>The inner pane (1) is only secured by hooking onto the shutter head rail (7). Easy access to the blind for repairs is ensured by lifting the U-profile (2) off the angle rail (4) . An extension of the U-profile (2) also serves as a cover (11).<\/p>\n<p>Schutzrechte\/Industrial property rights<br \/>\nEP 3976919<br \/>\nAu 2020269906<br \/>\nCa 53963-3003<br \/>\nUSA 17609297<br \/>\nDE10 2023 004 684.1<br \/>\nDE10 2024 001 557.4<br \/>\nDE10 2024 003 455.2<\/p><\/div><\/div><div class=\"x-col e723-e81 mk3-2j\"><div class=\"x-text x-text-headline e723-e82 mk3-2l mk3-2m mk3-2q mk3-2r mk3-2s mk3-2u mk3-2v\"><div class=\"x-text-content\"><div class=\"x-text-content-text\"><span class=\"x-text-content-text-primary\">Mullion-transom facade with <br \/>active cooling<\/span>\n<\/div><\/div><\/div><span class=\"x-image e723-e83 mk3-3z mk3-43 mk3-45 mk3-47\"><img decoding=\"async\" src=\"https:\/\/www.retrosolar.de\/wp-content\/uploads\/2025\/07\/Pfosten-Riegel.webp\" width=\"541\" height=\"895\" alt=\"Image\" loading=\"lazy\"><\/span><div class=\"x-text x-content e723-e84 mk3-2y mk3-30 mk3-31 mk3-32 mk3-34 mk3-35 mk3-36 mk3-37 mk3-3m mk3-3n mk3-3p\"><p>The angled rail (4) also serves as a support for a cooling tube (12) that absorbs the heat from the cavity or from the louvre head rail. The aim is to reduce the secondary heat radiation to the interior and to dissipate the radiant energy in the fa\u00e7ade zone without burdening the interior with heat radiation. While heat rises on the inside of the outer glazing (11), cold air falls on the inner glazing (8).<\/p>\n<p>The angled rail (4) forms a condensate collection channel. This enables the flow temperature to be lowered to the condensation temperature. Moisture on the cooling pipe jacket increases the heat transfer value \u03b1. In combination with retro solar shading, this results in a highly effective measure to protect the interior from external heat radiation. The design is also recommended for fa\u00e7ade renovations. g values &lt; 0.05 with open blinds and high summer sun are easy to achieve.<\/p>\n<p>Alternatively:<br \/>\nIt is advantageous to introduce dried and cooled air into the cavity from below through a supply air trunk, which either exits into the interior through joints at the top or is extracted via an extraction trunk. In winter, the introduction of dried warm air can also prevent condensation from forming on the inside of the outer glazing.<br \/>\n.<\/p><\/div><\/div><\/div><\/div><\/div><div
