很多济南业主装修完才发现问题：下午两点的西阳台，室内比室外还闷，空调开到24℃都不敢关机。窗帘只能挡光，挡不住热量透过玻璃往屋里灌——真正省钱的做法，是在窗外先加一层“外遮阳”。

Many homeowners in Jinan only discover problems after finishing their renovation: at 2 pm on the west balcony, the indoor air is even stuffier than the outdoor air, and they dare not turn off the air conditioning when it is turned on to 24 ℃. Curtains can only block light and cannot prevent heat from flowing into the room through the glass - the real way to save money is to add a layer of "external shading" outside the window first.

选遮阳棚不是看谁家图册好看，先按位置定类型：

Choosing a sunshade is not about looking at someone's picture book, but about determining the type based on the location:

阳台、飘窗、小门头 → 曲臂式伸缩棚，不用时收起来不挡采光，展开能压住西晒。

Balcony, bay window, small doorway → curved arm retractable shed, when not in use, it can be folded up to avoid blocking the sunlight, and unfolded to withstand the west sun.

商铺门头、咖啡外摆 → 法式固定篷或梯形篷，兼做招牌底衬，布料选抗UV亚克力，色牢度4级以上才不半年褪成灰。

Shop storefront, coffee outdoor display → French fixed canopy or trapezoidal canopy, also used as sign backing, made of UV resistant acrylic fabric, with a color fastness of 4 or above, which will fade into dust within six months.

庭院、车位、露台 → 固定铝合金骨架配PVC涂层布，抗风抗雨，长期不用收。

Courtyard, parking space, terrace → Fixed aluminum alloy skeleton with PVC coated cloth, wind and rain resistant, no need to harvest for a long time.

三个容易省错钱的点：

Three easy ways to save money:

篷布克重别低于650g/㎡，低于这个数济南夏天暴晒一两年就发脆开裂，别拿阳台防晒网当棚布用。

The weight of the tarpaulin should not be less than 650g/㎡. If it is less than this, it will become brittle and crack after one or two years of exposure to sunlight in Jinan during summer. Do not use balcony sunscreen nets as tarpaulins.

骨架壁厚写进合同：家用铝合金≥1.8mm，大跨度≥2.2mm；电动款电机防护等级IP65以上，带过载保护和遇阻回停，下雨刮风才敢自动收。

The thickness of the skeleton wall is written in the contract: household aluminum alloy ≥ 1.8mm, large span ≥ 2.2mm; electric motor protection level IP65 or above, with overload protection and resistance to stop, only dare to automatically retract in rainy and windy weather.

安装面承重先探墙：空心砖、加气块、外墙保温层不能直接打膨胀螺丝，建议加穿墙螺杆或背板。前檐留出10°–25°下坡角，不积水、不兜风。

Before installing the load-bearing surface, first explore the wall: hollow bricks, aerated blocks, and external wall insulation layers cannot be directly screwed with expansion screws, and must be equipped with through wall screws or backboards. Leave a 10 ° -25 ° downhill angle on the front eaves, without water accumulation or driving.

顺手养成两个习惯：篷布每月软刷清灰，别用高压水枪直冲电机和接缝；遇5级以上大风、暴雨、积雪直接收拢，再贵的棚也怕“硬扛天气”。

Develop two habits: clean the tarpaulin with a soft brush every month and avoid using high-pressure water guns to directly hit the motor and seams; In case of strong wind above level 5, rainstorm and snow, even the most expensive shed is afraid of "hard weather".
