House decoration chooses self-installation, how to find and buy system doors and windows, compare prices and construct (doors and windows stage)

environment:

Location: Hangzhou

Decoration type: self-installation

Area: 135 square meters of construction area

Progress: Purchase and installation of aluminum alloy doors and windows

Problem Description:

House decoration chooses self-installation, how to find and buy system doors and windows, compare prices and construct

solution:

1. Understand the knowledge about doors and windows

The difference between broken bridge aluminum and system windows

断桥铝：为铝合金是金属，导热比较快，所以当室内外温度相差很多时，铝合金就可以成为传递热量的一座“桥”，这样的材料做成门窗，它的隔热性能就不佳了。而断桥铝是将铝合金从中间断开的，它采用硬塑将断开的铝合金连为一体，我们知道塑料导热明显要比金属慢，这样热量就不容易通过整个材料了，材料的隔热性能也就变好了，这就是“断桥铝（合金）”



系统窗：系统门窗是一个性能系统的完美有机组合，需要根据气候变化综合考虑水密性、气密性、抗风压、机械力学强度、隔热、隔音、防盗、遮阳、耐候性、操作手感等一系列重要的功能，还要考虑设备、型材、配件、玻璃、粘胶、密 封件各环节性能的综合结果，缺一不可，最终形成高耐候性能的全候系统门窗。




系统窗一定是断桥铝窗，但断桥铝窗不一定是系统窗

系统窗一体成型，断桥铝像是组装的

1. Profile

brand

parameter

(1) 55, 90, and 108 refer to the width of the window frame, such as the 108-series window with a window frame width of 10.8 cm, which also occupies a position of 10.8 cm when the window falls on the balcony

(2) Aluminum profile 6063-T5, 6063 represents the grade of the aluminum alloy material. 6063 aluminum alloy is a medium-strength, heat-treatable strengthened platinum alloy, which belongs to the six-series alloy in aluminum alloys. T5 in aluminum profile 6063-T5 is the classification mark of heat treatment. The first digit after the word T indicates the basic type of heat treatment, that is to say, T5 indicates artificial aging after cooling from the molding temperature

2. Glass

brand

parameter

(1) The national standard glass thickness is 5mm, and the glass thickness depends on the size of the window

(2) Configuration: For example, 5mm+18A+5mm, which belongs to hollow double tempered glass, 18A represents the hollow thickness, and the sound insulation effect of hollow laminated glass is better

(3) Buy glass with different performances according to your needs, for example, three-glass two-cavity, laminated glass, four-glass three-cavity, etc. Many people only care about profiles, but ignore the glass configuration. A good door and window, glass 70% accounted for, profiles accounted for 30%

Add argon

中空玻璃充氩气和没有充气的区别是，冲氩气的中空玻璃，隔音效果和保暖效果更好，另外，里面不会有雾气出现。没有充气的中空玻璃的话，容易出现雾气。氩气是惰性气体，可以有效降低磁波共振，达到隔音效果。可以明显降低传热系数，有效阻止外片玻璃所吸收的热量向室内流入。对遮掩系数也有一定影响，惰性气体氩气可以有效的遮挡紫外线。降低玻璃两侧温度，减少玻璃表面结霜、起雾的现象，更可降低玻璃自爆的几率

Low-E glass

Low-E玻璃又称低辐射玻璃，是在玻璃表面镀上多层金属或其他化合物组成的膜系产品。其镀膜层具有对可见光高透过及对中远红外线高反射的特性，使其与普通玻璃及传统的建筑用镀膜玻璃相比，具有优异的隔热效果和良好的透光性。
玻璃是重要的建筑材料，随着对建筑物装饰性要求的不断提高，玻璃在建筑行业中的使用量也不断增大。然而，当今人们在选择建筑物的玻璃门窗时，除了考虑其美学和外观特征外，更注重其热量控制、制冷成本和内部阳光投射舒适平衡等问题。这就使得镀膜玻璃家族中的新贵——Low-E玻璃脱颖而出，成为人们关注的焦点

When purchasing doors and windows, be sure to ask clearly what the glass configuration is, whether to add low-e or argon. Whether the glass is artificially glued or pimped, the most important point is whether to install the glass with micro-foam glue. The advantage of this is that the glass and the profile are more sealed and the sound insulation effect is better.

Good product + good installation process = value

3. Hardware

brand

1. What should the appearance of door and window hardware look like?

It mainly depends on the coating of the product, whether the surface is smooth, etc. The appearance is the direct standard for judging the quality of a hardware product

2. How to look at the material and performance

Ask the merchant what the material of the handle is. Generally, the material of the handle is zinc alloy, aluminum alloy, or stainless steel; and ask if there is any performance test report, such as salt spray test, opening and closing test, etc. Then try to see if the operation is easy and smooth

3. When choosing a brand, you must be sure whether it is really imported

Many door and window manufacturers often say that their hardware is imported hardware, but it is actually an OEM product. You must pay attention to doing your homework when purchasing

4. Major imported brands

At present, the brands in the home improvement door and window hardware market are basically imported brands, and the brands with a relatively large market share mainly include CMECH from the United States, Hoppe from Germany, Giesse from Italy, Roto from Germany, GU from Germany, etc.

5. How to choose a brand

Door and window hardware brands currently have a good reputation in the market, mainly CMECH from the United States and Hoppe from Germany. Among them, Hoppe mainly produces handle products, and the quality of the handle is good. CMECH mainly produces a full set of door and window hardware products, and the products are all They are all self-developed and self-produced. At present, CMECH still has its own factory in China. Many first-line door and window brands use its products, which are still very good.

4. Precautions

														
1、安装前检查窗户材料是否是自己选定的厚度和系列，有无磕碰铝材检测报告6063T5是原生铝材原生铝材截面光亮度高			
														
2、安装用自切螺丝或不锈钢拉爆螺丝，不要使用小黄鱼														
												
3、螺丝内外交叉大，不要打在隔热条上，间隔40公分打一颗														
														
4、装大玻璃，框架底部的缝隙用水泥沙浆填满，不然装玻璃易下沉														
														
5、窗框外延用卫生间剩下的防水刷两遍，干了贴砖或者用不锈钢铝板做斜水坡														
														
6、安装好的窗框，室内不要为了美观只刮灰，内外都要打耐候结构胶														
														
7、提醒安装师傅注意安全														
														
8、隔热条选尼龙PA66，隔热条宽度24mm够了30mm非常好了														
														
9、玻璃材质一定选带3C标志钢化玻璃，双层中空玻璃，中间空隙在9～15mm,填充氩气，防雾														
														
10、密封胶条选三元乙丙材质玻璃压条，抗老化收缩														
														
11、五金件成套买，国内Hopo,派格；进口的希美克、格屋，购买前试一下是否顺滑														
														
12、金刚网纱窗可选快拆式，比传统合页结构安全，拆洗方便														
														
13、合同中要把计价方式，售后、搬运费、拆旧费写清楚，问清楚开启扇、五金、护栏、纱窗是否另算														
														
14、每平预算500以下不建议选，每平预算800左右可选择派雅、亿合														

Second, looking for door and window suppliers

1. Introduction of acquaintances

There are relatives and friends who have renovated the introduction

2. Consultation with neighbors installed in the same community

In the same community, there are on-site visits and consultations where the doors and windows have been renovated and installed

3. Search online store

Search on Taobao, Douyin, and Xiaohongshu

4. Search on the map

Search nearby stores and factory stores

5. Physical store consultation

Inquiry about physical stores near the community

I have tried all the above 5 methods, and finally found a local factory store

3. Measurement and customization

1. Select 1 acquaintance introduction and 4 local factory stores, let them come to measure the size for free, and give a plan and quotation

Acquaintance Introduction (Personal Boss)

Offer sheet

Others make a case map in his home

local factory store

Introduce the product first

parameter

1. 5mm+18A+5mm double-layer hollow tempered glass (integrated bending process)
2. Holland Akzo powder spraying process paint surface
3. Standard Xiongao handle
4. A full set of Sekel dust-proof hardware, with anti-falling rope
5. 6063T5 primary aluminum material
6. Glass filled with argon gas has better sound insulation and heat insulation performance
7. EPDM sealing strip
8. PA66GF25 nylon heat insulation strip
9. Standard 304 stainless steel gauze (high-definition net, thickened net optional)

4. Quotation Form & Contract Signing

signing the contract

After many product and price comparisons, bargaining and negotiation discounts, reached a purchase intention with a local factory store and prepared to sign a contract

合同细节：

1.工期要求
如果家里装修比较赶，或者门窗订货有点迟了，可以重点关注下时间期限，一般来说，定制门窗从下单到安装的时间为20-50天左右，和商家提前确定大致工期，并最好约定期限限制，如延期一天赔1%

2.安装条款
选购时应提前了解商家的施工水平、安装验收标准、辅材用料等，并在签订合同时强调，同时落字为据。
提前了解、约定易推诿的一些安装细节，如①门窗拆旧工作谁来做，是否要收费；②洞口处理、防水谁来做，是否收费；③垃圾清运、安装后产品保护谁来做等

3.安全施工
门窗施工属于登高、临边作业，有一定的风险，合同中一定要强调安全问题，如搭阳光房、门窗室外打胶时，安装人员应系带安全装置。
同时最好要明确责任，即合同中加一条，门窗安装发生安全意外时，非消费者或第三方原因导致的安全事故，由施工单位全权负责，甲方无需负责
施工作业人员保险
这一点是鉴定正规军与游击队最有效的方法。目前很多的门窗厂家都是临时雇佣几个安装工人，没有统一的作业标准，安装质量不能保证。有保险的工人，基本上是常年给厂家安装的，专业性更强，可以放心使用

4.验收条款
选购前提前了解「商家有无验收服务，验收标准是怎么样的，不符合验收时的解决方案是怎么样」后，在合同中落字为据

5.质保期
合同中还应注明门窗产品的保修范围，保修期，与收费情况(视商家和产品而定)
保修范围一般有产品本身质量、安装问题(门窗渗漏、材料破损老化等)、产品使用问题(密封不回、开启不便等)等

门窗保修期一般在1-5年左右，时间相对越长用户使用越省心。
同时保修或维修的收费情况应注明，如保修期限内，提供无条件维修服务，保修期限外，提供有偿维修服务

6.盖公章
这个同样也很重要，最好要求厂家提供营业执照，便于核对公章真伪

final contract

如果颜色做双色，我是外咖内白，白色竟然没平方要40块另外收费，要特别问清楚老板

5. Order payment & arrange production

Pay according to the requirements of the contract, and send the screenshot to the business manager. After the completion, the manufacturer arranges production, and confirms the order content again before arranging production.

6. Shipping & Installation
