窗的历史

为了遮风挡雨，更为了居住采光、通风的需要，人类发明了门窗，从山顶洞人以洞口为窗开始，门窗的发展史同时记录着人们追求美好生活的进步史。 在门窗产品发展史中，塑钢门窗是继木窗、钢窗、铝合金窗之后的第四代新型门窗产品，它是以聚氯乙烯（PVC）为主要原材料，加上一定比例的稳定剂、着色剂、填充剂、紫外线吸收剂等，经挤出成型，然后通过切割、焊接的方式制成门窗框扇，配装上密封胶条、毛条、五金件等，并在型材空腔内填加钢衬，以增强型材的刚性和抗压能力。 塑钢门窗具有木、钢、铝门窗不可比拟的水密性、气密性、耐腐蚀性、保温隔热性及环保节能等方面的性能优点，并以其优良的物理性能和多样化的产品设计，越来越成为广大消费者首选的建筑门窗。

型材

产品特点

先进的设备 -
全套引进德国、奥地利最先进设备，全套进口的挤出设备及型材模具，采用计算机控制操作，保证生产出来的每根型材质密均匀、光洁度高，功能尺寸、腔体结构完全符合要求。
优良的配方 -
引进德国配方，采用国际上先进的加工助剂，经过精心的选料和严格的操作，使海螺型材的物理机械性能远高于国家标准，尤其是型材性能的重要指标，角强度的抗老化性能方面，保证了海螺任一系列、任一品种端面的型材焊接角强度远大于国家标准3000N，人工老化1000小时后，无显著变色。
型材端面设计 -
均为多腔体结构，有独立的排水腔、增强型钢腔、保温腔，使水无法进入增强型钢腔体，避免型钢生锈，提高门窗的使用寿命，排水腔能保证框扇的积水及时的排出，保证门窗的水密性。
外观质量 -
色系为淡青色，色泽柔和，线条流畅，给人以清雅的感觉，外形尺寸精度高，给门窗的组装质量提供了保证。
性能稳定 -
型材经高低温反复处理后，尺寸基本无变化，加热后无气泡、麻点和裂痕。
出材率高 -
为满足不同消费者的需要，有多种型材组合供用户选择，使用海螺型材既能保证门窗的质量，又提高了组装厂的经济效益。

通用性、灵活性 -
不同系列、不同类型的门窗压条之间可以互换，即可安装不同厚度的单层、双层、三层玻璃。
推拉框无论是双轨或三轨：扇既可安装滑轮直接在轨道上推拉，又可将轨道上塑料条撕掉，安装上铝划轨后，扇装滑轮在轨道上推拉。
所有型材装压条、密封条、毛条部位的功能尺寸相同，便于所配套的辅件规格统一，有利于组装操作。
安全性 -
所有塑料门窗的玻璃压条朝向室内，便于更换玻璃，具有防盗功能。
性价比 -
与达到同等性能的木、钢、铝窗等同类型产品相比，海螺型材组装的性价比更高。

Technical

In Europe where the UV factor is not prevalent, their uPVC powder formulation contains an ultra-violet inhibitor, Titanium Dioxide, of which only 2% is required for European conditions. After several years of conducting stringent tests and experiments by the CSIR to overcome the harsh UV rays experienced in our country, it was established that the Titanium Dioxide requirement was 5%. Therefore for added assurance, the quantity of Titanium Dioxide was increased to 7%.

We are therefore confident that our product will endure all weather conditions for an indefinite period of time. As a result, the user need not be concerned with warping, rotting, corroding, scraping and painting of the window frames. The only maintenance required is the occasional wipe down of the frames and lubrication of the locks and stainless steel hinges.

We are using the same tested and approved multi-chambered as used in Germany.

Frame Construction and Wind Loading
The largest chamber of the frame is supported by galvanized steel or aluminium rectangular tubing, giving it rigidity. The frames can accommodate glass thickness from 3mm to 20mm. The frames are fusion welded, therefore ensuring that the chambers in the profile are sealed and remain completely separate to each other.

The galvanised steel / aluminium reinforcing is totally encapsulated in the chamber designed to hold it. uPVC has a memory and therefore seals itself around any self-tapping screws that enter the profile.

As a result of this design, the window frame structure provides an excellent insulator for noise and temperature control, which is often needed for offices in noisy locations.
Furthermore, our windows are subjected to cyclonic and adverse weather conditions testing. These conditions are simulated with winds of up to 240km per hour, driving rain and time and Ultra Violet acceleration.

Advantages of uPVC

• Excellent insulator
• Reduced air infiltration
• Resists condensation
• Easy to clean
• Durability - No pitting, peeling, rotting, drying out, or corroding
  Virtually maintenance free
• Easy operation
• Custom size of opening
• Solid colour throughout
• Never needs painting
• Integral lift rails, interlocks and weatherstripping pockets

What is uPVC?

uPVC has properties which in many instances allow it to be used instead of, and very often give it advantages over steel, cast iron etc.

The main advantages uPVC has over other materials -

• It is not affected by contact with cement.
• The colour goes through the complete wall thickness of the material (2 - 3mm).
• If it is scratched, the marks can be polished out with various grades of water paper.
• The corners are welded (not mechanically joined).
• It cannot corrode, even with direct contact with salt water.
• Double seals between sash and frame ensures the best NOISE and weatherproofing possible.

uPVC window and door frame

uPVC window and door frames contain an ultra violet inhibitor, that is ideal for climates experiencing harsh UV rays, as well as those with heavy rainfalls and humidity.

uPVC window frames have been extensively used in Germany and the Scandanavian countries for more than 30 years with great success. They were introduced to the United Kingdom in 1982 but received a cool reception by skeptics. However, by 1984 uPVC started gaining acceptance and by 1986 controlled approximately 60% of the new window market. Today aluminium frames are nearly non-existent in the domestic market. In the United States of America in 2002, there were 34,2 million uPVC windows sold compared to 5,5 million alumnium and 19,8 million wood.

We at ESI Design uPVC are very optimistic about the future of our product judging by the acceptance of architects, developers, government bodies and of course, present sales.

The main advantages ESI Design uPVC Windows & Doors have to offer over other materials:-

1. It is not affected by contact with cement
2. The colour goes through the entire wall thickness of the material (2-3mm)
3. If it is scratched, the marks can be polished out with various grades of water paper
4. The corners are welded and not mechanically joined
5. It cannot corrode, even with direct contact with salt water
6. Double seals between the sash and the frame ensure the best noise and temperature control as well as excellent weatherproofing.
7. It has a 10-year warranty issued by the largest uPVC profile company in the world.
8. Glazing is done from inside on most systems, for extra security.
   

Our window and door profiles carry the following certification:-
SABS - RAL - BSI - SII - EN ISO 9001 - ISO 9002
