When winter arrives and the cold winds are raging, many homeowners feel that their windows are leaking. There are three causes of window leaks: poor materials, poor installation and faulty fittings.
Reason one: poor material
Nowadays, the material of windows is mainly made of aluminum and plastic steel, while aluminum alloy windows and doors have been gradually eliminated due to their poor sealing performance. But even if you buy plastic steel windows and bridge-breaking aluminium windows, you should also pay attention to the material. If the material is poor, the windows will be deformed in two or three years, and once deformed, the sealing performance will be poor and wind leakage will occur, so this also reminds owners to pay extra attention to the material when buying windows.
The solution: only find a window manufacturer to solve the problem.
Reason 2: Not in place for installation
Even with a window made of good materials, the installation process is an important factor in determining whether the window is leaky or not.
First of all, the window must be installed correctly, otherwise the window may become more and more crooked after a period of time, and the gap between the window frame and the wall will become bigger and bigger, and wind leakage is inevitable. Secondly, when the window is installed, the gap between the window frame and the wall needs to be filled with styrofoam. After the foam has cured, the perimeter of the window frame is then evenly coated with sealant to prevent rainwater from seeping into the room through the gaps between the window and the wall, and to prevent wind leakage. It is also necessary to apply glue to both the inside and outside of the window. Some workers try to save time by gluing only the inside, or gluing a few points on the inside, which is not sealed tightly. Even if the exterior is glued with styrofoam, it will chalk up in a year or a year and a half or so, and water leaks in summer and draughts in winter will occur. In addition, when the decoration, home improvement workers found that the window frame and wall seam gaps are not sealed tight, then will be filled with putty from the inside, but over time, there will also be a kind of subtle seam, resulting in wind leakage.
The solution: kind of situation has to find the window manufacturer. If it is only the window internal glue is not played well, the gap is also relatively small, you can put on your own beauty paper, towards the gap to play the sealant can; if the external glue has problems, you need to contact workers to operate.
Cause 3: Faulty fittings
Another important cause of window leakage is the failure of sealing accessories. A common one is the aging and cracking of the seal, which directly leads to poor window sealing performance; there is also a kind of foam rubber that is too soft and chalked after a few years of use, leading to a larger gap between the window frame and the wall, resulting in wind leakage.
Solution: you can replace the seal yourself, using EPDM rubber is better, or slightly poorer quality rubber and plastic strip can also be; if you can not operate, find the street to do plastic windows shop workers to replace the cost is not too much. As for the styrofoam, you need to find workers to operate, after the styrofoam curing, owners can pinch themselves to see, the quality of the effort to pinch the better.
Winter home construction tips
Different seasons have different requirements for decoration, winter is coming, home construction has a few tips to note.
1. carpentry work to leave a seam
To leave a proper construction gap. When laying solid wood flooring, around to leave about 2mm expansion joints, otherwise it will cause bulging, overhanging phenomenon; do furniture, the door seam should not be too small, so as not to summer expansion tight, not close tight.
2. Putty should not be scraped too thick
Because the indoor air is dry and water loss is fast, the putty before oiling cannot be scraped too thick, otherwise it will easily cause hollow drums, cracks and wall inequality.
3. Wall and floor tiles can only be paved after warmth
Whether wall or floor tiles, need to move from outdoor to indoor transition 24 hours later, adapt to the indoor temperature before paving, so as to avoid construction after the phenomenon of hollow drums, shedding. In addition, brick paving should be promptly hooked after the seam.
4. timely ventilation attention to fire prevention
Rubbish should be cleaned up at any time, wood chips, wood chips and other flammable materials at any time, paint and other items should be placed separately in the balcony and other places of ventilation.
5. The ambient temperature of the paint should be suitable
The ambient temperature should be above 0°C for the construction of mixed colour paints and not below 8°C for varnishes. Therefore, during the winter months, it is important to keep doors and windows closed to ensure that the indoor temperature is at least 5°C. The heating of the interior should be moderate, with no more than 20°C being appropriate.
How to identify the wear resistance of the floor?
Flooring because of the usual will be frequently stepped on, and sometimes also suffer from bump, scraping carved “ordeal”, its wear-resistant performance has been a hot spot of consumer concern. Laminate flooring and solid wood flooring, solid wood laminate flooring wear resistance performance is very different, flooring manufacturers have also been to wear resistance performance as a selling point, consumers should be how to identify and choose it?
Laminate flooring: high wear resistance but lack of texture
High wear resistance is one of the outstanding properties of laminate flooring. In the “impregnated paper laminate wood flooring” this standard stipulates that the laminate flooring used in the home environment, the first level of wear resistance indicators for more than 5,000 revolutions, the second level for more than 4,000 revolutions. For the average family, 4000 rpm is sufficient to meet the basic usage requirements. The laminate flooring has a special layer of aluminium trioxide wear paper, the content and distribution of which determines its wear resistance. Generally speaking, the more the content of aluminium trioxide in the wear-resistant layer, the more evenly distributed it is, the better the wear resistance of the floor will be, and these will be reflected in the wear resistance rpm. Therefore, consumers can examine the wear resistance of laminate flooring by simply checking the number of wear-resistant revolutions in the test report. As the laminate flooring surface wear layer and decorative layer, is the use of bionic technology printed paper, and solid wood or solid wood laminate flooring compared to its overall laying effect is not so realistic, the visual effect is more rigid.
Common solid wood: Careful maintenance required
Due to the raw materials, structure and technology in the product and laminate flooring is very different, ordinary solid wood flooring, solid wood laminate flooring mostly using paint surface as the surface layer, its wear resistance than laminate flooring is much inferior. The requirements for the wear resistance of solid wood and solid wood laminate flooring are also low, and the testing standards are different from those of laminate flooring, and are not measured by the number of revolutions. The main advantage of these two types of flooring is its comfortable feel and real wood texture. The Solid Wood Flooring Standard states that the surface wear resistance of a lacquered board ≤ 0.15g/100r is a qualified product. The wear resistance of these two types of flooring can also meet the needs of the average family if they are very well cared for and maintained after laying, as long as they are qualified products.
