Exterior walls and windows: Completely soundproof and lightproof from the outside

Treatment of the guest room's exterior opening: the window is double-layered, with an air gap of 100mm or more between the two layers of glass. The thickness of the two glass layers is deliberately different to stagger their resonant frequencies, and the window frame is of the highest airtightness rating. Outside the window, there is an additional electric blackout roller blind; when fully lowered, the interior can achieve near-total darkness. The window's position only faces an internal courtyard or a direction with a solid wall for shielding. The image presents a cross-section showing the layers of the window, with labels for glass thickness, air gap, and airtight seals. Next to it is a photo of the interior in a completely blacked-out state. Avoid: using single-layer glass, both glass layers having the same thickness, blackout blind leaking light, window facing an adjacent building or street.

客房的對外開口處理:窗是雙層的,兩層玻璃之間留 100mm 以上的空氣層,兩層的玻璃厚度刻意不同以錯開共振頻率,窗框是氣密等級最高的。窗外另有一道電動的遮光捲簾,完全放下時室內可以達到接近全黑。窗的位置只朝向內部中庭或有實牆遮蔽的方向。畫面以剖視呈現窗的層次,並標示玻璃厚度、空氣層與氣密膠條的位置。旁邊有室內完全遮光的狀態照片。避免:使用單層玻璃、兩層玻璃厚度相同、遮光簾漏光、窗朝向鄰棟或街道。
