How to choose doors and windows, with good sound insulation and thermal insulation effects?
There are no more than three points: the sealing structure of the product, the selection of glass, and the most important installation and landing. When considering lighting, anti-theft, ventilation, and other situations, most households do not have high actual needs for sound insulation and insulation (otherwise everything would have to be compromised), so the following are only some key points:
(1) Most door and window products have a sound insulation effect between 20-35 decibels, with sliding windows being relatively poor and windows being relatively good; When the indoor temperature is between three to four tenths, it is already quiet;
(2) In most cases, such as on the roadside of residential areas, a product with a relatively good sealing structure and insulated glass is sufficient;
(3) In some cases, such as facing the street, using hollow laminated glass or having indoor door partitions can also achieve good results;
(4) The sealing structure of doors and windows (window opening) depends on the adhesive strip: the brand, material, elasticity of the adhesive strip, the overlap amount of the adhesive strip, the shape variation when closing the window, the difficult to handle position of the edge and hinge of the adhesive strip, the effective sealing of several layers of the adhesive strip without the drainage channel, and the key manufacturer's work. The factory quality varies greatly between good and bad manufacturers, which can be said to be:, Some large brand two seal structures can instantly kill the three seals of small and medium-sized factories in practical product applications;
(5) In addition to the sealing effect of the "adhesive strip hardware" mentioned above, the insulation and insulation effect of door and window products is also important in terms of the width of the insulation strip and the selection of the glass;
(6) Select insulation strips with a width of 20mm or more (30mm), and choose low e insulating glass or three glass two chambers, or better configurations, which can generally meet the requirements.
