Apr 19, 2018

timg.jpgThe window sill is made of plywood and veneer made of wood, and can also be made of cement and stone. The style of the sill plate is mainly categorized from the material. Common materials include marble, granite, artificial stone, decorative panels and decorative wood lines.

1. Marble

Marble should be the first choice for window sill, but the premise is that the selected color texture is ideal. The marble sill plate has the advantages of beautiful colors and various textures. The countertop can prevent splashing rain. However, marble may have radiation and it is not good for the body, so it is not recommended to use it in the bedroom.

2. granite

Granite texture is basically dominated by granules, and there are a variety of colors. Its color and texture are inferior to marble, but it is harder and more durable than marble.

3. artificial stone

Artificial stone has high hardness, high abrasion resistance, high temperature resistance, environmental protection, non-toxic, tasteless and non-radiative. It also has more colors and higher grades, and can maintain a good finish for a long time.

4. composite acrylic

Acrylic's biggest advantage is that it can do any modeling, and his seamless stitching technology cannot be replaced by any other material. At the same time, Acrylic is slow in heat conduction, and when you meet a large window in the room, sitting in the window of the sun in the winter is warm and pleasant. It really is a kind of enjoyment. The disadvantage is that acrylics that are too solid may yellow due to long-term sunlight exposure. Therefore, when choosing acrylic as the window sill, it is best to choose yellow and warm


5. Wood

Wood paneling can reflect the simple wood texture, highlighting the natural flavor. People feel warmer. However, the disadvantage of wood is that it cannot be shaped. Edge sealing is a big problem. The plate itself is easily deformed and cracked under the long-term sunlight exposure.



Sill plate size

The size of the sill plate should be measured to be larger than the actual sill size, increase the width of the exposed wall edge and the length of the ears on both sides. Such as the size of a single window, usually in the length of two more plus 3 ~ 5 cm can be, commonly known as "ear"; In addition, the front also has to explore out a few centimeters, which is the actual width of the window sills than the thickness of the bottom of the 

window sill wide, at least wide 3 cm. Sill plate width = actual window sill width + widened width 3.5CM; sill plate length = actual sill length + ear length (3 ~ 5CM) X2 edge; ledges are generally as wide as possible, wider and more beautiful, also Easy to put flower pots and so on. However, it should be noted that if the width inside the window sill is relatively narrow, the window sill cannot detect too much. If there are more vacant places, the ledge will not be strong.

Marble window sill installation process

1. Grassroots cleanup

The base layer should have sufficient rigidity and stability. The surface of the grass-roots level should be smooth and clean, and the smooth surface of the grass-roots should be subjected to a cutting process in order to facilitate the bonding of the base layer and the veneer. The protruding part of the concrete surface should be leveled and then moistened by watering.

2. Bottom gray

Wipe thick 12mm 1:3 cement mortar, find rules, use a short wood carpenter to flatten, and draw hair.

3. Positioning line

According to the design drawings and the actual site of the paste, as well as the size and size of the sill trim panel used, the horizontal and vertical lines are popped to ensure that the board joints are tight and impermeable. When considering the seam width of the panel, it is generally not more than 1mm.

4. Paste the veneer

Wet and wet the bottom ash, apply a thin layer of plain grout to the surface to be affixed, and then apply the wetted, dry screed on the back of the marble sill plate 2-3mm thick. The plain grout, paste it, stick it and tap it with a wooden hammer to fix it. When sticking, you should use the ruler at any time to level and find the straight, and use the bracket to stabilize the ruler, then wipe out the mortar that flows out to avoid contaminating the adjacent decoration. For smaller areas, it can be directly affixed with an adhesive such as epoxy.
