After all, we have no control over the outdoor temperature, but we still have the final say on the temperature in our own home. If we want to have a better indoor cooling effect, we must pay attention to the choice of doors and windows when decorating. Doors and windows with good heat insulation performance should be How to choose?

Performance inspection report and K value of doors and windows

Now many home improvement door and window brands will submit their various product series for inspection, and the professional inspection unit will obtain specific performance parameters such as air tightness, sound insulation, and thermal insulation of doors and windows.

The heat transfer coefficient of doors and windows, that is, the K value. It is the main index used to measure the thermal insulation performance of doors and windows. It refers to the heat transferred through an area of 1 square meter within 1 hour when the air temperature difference on both sides of the enclosure structure is 1 degree (K, ℃) under stable heat transfer conditions. In layman's terms, the lower the K value, the better the insulation performance of doors and windows; the higher the K value, the worse the insulation performance.

Thermal insulation——Built-in louvre insulating glass

The built-in louvred hollow glass window can take into account the sunshade and heat insulation of the external window in summer and the heat preservation in winter. In summer, it can significantly block solar radiation heat and reduce the energy consumption of air conditioning and cooling; in winter, it has the function of heat preservation and can reduce heating energy consumption. In short, in summer and winter, it can well improve the indoor thermal environment and achieve a satisfactory energy-saving effect. In addition, the hollow glass window with built-in louvres also has many characteristics such as adjusting sunlight, reducing noise, and protecting private space. It can take into account the requirements of energy saving and dimming in different climates. It is an energy-saving exterior window with dynamic dimming performance. External windows have gradually been popularized and applied in various regions of our country.

Advantages of hollow built-in louvres

1. No-cleaning for life: Because the louvres are inside the insulating glass, no dust will accumulate, which can save the trouble of cleaning the curtains.

2. Safety and fire prevention: Inert gas is filled inside the insulating glass, which can play a role in isolating flames from burning.

3. Building energy saving: the hollow louvre is filled with inert gas, and its heat insulation is better than that of ordinary glass. Due to its excellent heat insulation performance, it can better achieve indoor heat insulation effects. When closing the window, it can make the indoor sealing effect better and save energy. Air conditioning energy can also be used with LOW-E glass, which has better performance and is more energy-saving.

4. Strong sound insulation: Inert gas will be filled between the double-sided glass of the hollow glass built-in louvre, and the product has strong sealing performance, coupled with the high-efficiency sound insulation of the broken bridge aluminium, the sound insulation effect of the hollow built-in louvre is first-class, which can greatly isolate or reduce noise.

5. Stylish appearance: everyone likes different styles for appearance. If you prefer the appearance and light and shadow of the blinds, then the built-in blinds can save the trouble of cleaning, and it is definitely a better choice.
