As a special door and window system for ultra-low energy consumption buildings and near-zero energy consumption buildings, WinGreen aluminum alloy polyurethane composite doors and Windows continue to develop and improve in the development process of passive ultra-low energy buildings in China, and the product series has covered all product series of ultra-low energy and near-zero energy building external protection structure. After more than ten years of project practice, the product solution is mature and reliable, and will create greater value for the realization of China's dual carbon goal. At present, the product series has been certified and evaluated by relevant organizations, and has been entered into the PKPM software system, and provides architects with more reliable options for building energy saving optimization design.

Reference standard for ultra-low energy consumption and near-zero energy consumption doors and Windows (Shanghai) :

Ultra-low Energy window:

Whole window heat transfer coefficient K value ≤ 1.4W /m2.K; Glass shading coefficient SC≥0.6 Visible light filtration TL≥60%, air tightness 8, water tightness 5, wind pressure resistance 9

Near zero energy window:

Whole window heat transfer coefficient K value ≤1.0 or 1.2 W/m2.K; Glass shading coefficient SC≥0.6 Visible light filtration TL≥60%, air tightness 8, water tightness 5, wind pressure resistance 9

Second, the optional high-end thermal insulation aluminum alloy window system in PKPM system:

At present, in PKPM software (V4 or above version can be), the recommended high-end thermal insulation aluminum alloy door and window system and can meet the above design standards are: aluminum alloy polyurethane composite window system (PU broken bridge aluminum doors and Windows), its program level and parameters are as follows:

Third, PKPM system selection of aluminum alloy polyurethane doors and Windows method:

1, Material editor "Material selection" search: aluminum polyurethane... As shown in the picture below:

2, if you do not search, in the material editor "material selection" interface, the system will also actively push: aluminum alloy polyurethane window system... As shown in the picture below:

3, in the material editor "material selection" interface "heat transfer coefficient" option can also be screened and queried

Fourth, Aluminum alloy polyurethane composite doors and Windows are special doors and Windows systems for ultra-low energy consumption and near-zero energy consumption buildings (core advantages)

1, the insulation performance is super strong, three-glass two-cavity single-layer single silver low-e can meet the performance requirements of unfavorable window type, and the measured K value is 1.2-1.3, providing a reliable guarantee for future acceptance.

2, single silver high-permeability Low-e glass configuration, so that doors and Windows have ultra-high visible light transmittance, more transparent and bright. High shading coefficient, far better than the standard requirements.

3, 75 series minimalist design, is the smallest frame glass ratio of domestic ultra-low energy Windows and doors, the narrowest side of the design style, more transparent.

4, the country has the most ultra-low energy consumption completed project cases (more than 300+), mature program, rich construction experience, to provide reliable guarantee for acceptance (aluminum alloy doors and Windows).

5, the certification system is the most complete, the whole series of products through the German passive housing Institute PHI certification, the Ministry of housing certification, national green building materials product certification

6, can provide a full range of product solutions: including external window, internal window, hanging window, sliding door, unit door, entry door, fire-resistant door, curtain wall, frame and other ultra-low and near-zero energy building perimeter protection product solutions.

7, the strength of the product is higher than that of ordinary broken bridge aluminum, strong wind pressure load resistance, typhoon resistance, to meet the needs of areas with high basic wind pressure along the river and coast. Superior durability and weather resistance, to create the longest service life cycle, good stability, the earliest domestic ultra-low energy project case is China's first passive ultra-low energy project ten years ago.

8, industry design consulting and experts are highly recognized, can represent the future development trend of ultra-low and near-zero energy Windows and doors technology solutions, has been in many places in Shanghai proofing.

9. The air tightness (grade 8), watertightness (grade 6) and wind pressure resistance (grade 9) of WinGreen's products can reach the highest standards of relevant tests in China and Europe. The excellent thermal insulation performance is the most outstanding advantage of WinGreen's brand series products. The heat transfer coefficient of WinGreen 75 series is as low as 0.88W /(m2·K), the heat transfer coefficient of flat door is as low as 0.77W /(m2·K), and the heat transfer coefficient of balcony sliding door is as low as 1.3W /(m2·K).

It is suitable for the application of ultra-low energy consumption projects in different regions, and achieves high cost performance in procurement cost, maintenance cost, construction and use. WinGreen's products have beautiful design, environmentally friendly production process, full solid thermal insulation, safety and reliability, and bring comprehensive improvement of energy saving, environmental protection, economy and comfort to buildings
