Neuschwanstein Castle
Key numbers
Background
Neuschwanstein Castle was originally commissioned to be built by King Ludwig II of Bavaria, with work commencing in 1869. However, Ludwig died before it was completed, and in 1886 the spectacular building was opened to the public. The Singers’ Hall was one of the king’s favorite projects, extending over the entire fourth floor, but over the years, dust and dirt, and the impact of the elements, meant the beautiful original lead windows needed glazing protection in order to be preserved for future generations.Task
The key consideration for this project was that the original 19th century lead-glass windows had to be protected from extreme weather conditions and UV radiation. At the same time, they were no longer protecting the interior from the effects of the sun and energy loss. Another significant aspect was that views of these exquisitely patterned windows enjoyed by visitors could be optimized using the right glazing protection.Solution
SCHOTT’s expertise in anti-reflective protective glazing and knowledge of historical architecture resulted in the decision to use AMIRAN® glass to protect the windows. Mounted outside the valuable original glass, sheets of SCHOTT AMIRAN® Heritage Protect were fitted as a laminated safety glass with a 0.76 PVB film to enhance their durability and UV resistance. The glass is ventilated from the rear and held in place by fastening irons glued into holes in the natural stone exterior of the castle, with stainless steel brackets screwed to the irons to ensure a robust and stable long-term solution.Minimal reflectance for maximum impact
The AMIRAN® range of anti-reflective glasses offers a number of advantages over conventional float glass thanks to SCHOTT’s fine-tuning of key technical properties. AMIRAN® Heritage Protect produces negligible reflection, high light transmission, and strong protection from mechanical and environmental hazards. The glass generates just 1 % luminous reflectance, and even as the angle of viewing is adjusted, the reflectance remains minimal. This is vital considering that ornate, historical windows such as those at Neuschwanstein Castle will frequently be viewed from the side or below.Strong protection inside and out
The addition of AMIRAN® Heritage Protect glazing will preserve Neuschwanstein Castle’s unique lead glass windows for many years to come, while also protecting the historic interior, fixtures and fittings from sun damage. The high level of color rendering achieved by AMIRAN® offers highly accurate light transmission, providing the best possible view of this timeless attraction, whether experienced from the inside or outside, regardless of viewing angle.Used materials & similar products
