1, rough calculation method for floor tiles:
Room floor area ÷ Area of ​​each floor tile × (1+10%) = number of bricks (where 10% means increased loss)
Accurate calculation method:
(Room length ÷ brick length) × (Room width ÷ brick width) = Room with a number of bricks 5 m long and 4m wide, 400mm × 400mm
Take the standard floor tile as an example:
5m÷0.4m=12.5 blocks (take 13 blocks) 4m÷0.4m=10 blocks
13 × 10 blocks = 130 bricks in total.
When purchasing, additional loss of about 3% -5% is required.
2, wallpaper common wallpaper specifications: each roll length 10m, width 0.53m.
Rough calculation method:
Floor area × 3 = Total area of ​​the wallpaper Total area of ​​the wallpaper ÷ (0.53m × 10) = Number of wallpaper rolls Accurate calculation method:
Wallpaper per roll length ÷ Room actual height = number of components used Perimeter of room ÷ Width of wallpaper = Total number of used units Total number of used units åˆ†é‡ Number of used units = Number of used wallpapers Fixed wallpaper specifications Therefore, when calculating its usage, pay attention to the actual length of the wallpaper. Usually, the actual height of the room should be used to subtract the height of the skirting board and the top line. In addition, the door and window area of ​​the room should also be subtracted from the number of components used.
This calculation method is suitable for plain or fine-grained wallpaper. In the collage of wallpapers, the bigger the pattern is, the bigger the pattern is, and the greater the loss, so it is about 10% more than the actual amount.
3, composite floor common specifications: 1.2m × 0.19m
A rough calculation method:
Room floor area ÷ (1.2m × 0.19m) × 105% = exact calculation method for the number of floorboards:
(Room length board length) × (Room width board width) = Number of floorboards Take 5m long and 4m wide as an example:
Room length 5m ÷ 1.2m ≈ 4.17 (block) Take 5 (block)
Room width 4m ÷ 0.19m ≈ 21.05 (block) Take 2l blocks Total plate: 5 × 21 blocks = 105 blocks Composite wood floors often have 3% -5% of the loss in the pavement, if calculated by area, thousands Don't ignore this amount of usage.
4, common specifications of solid wood flooring: 900mm × 90mm × 18mm, 750mm × 90mm × 18mm, 600mm × 90mm × 18mm
A rough calculation method:
The floor area of ​​the room, each floor area × 1.08 = the exact calculation method for using the floor number:
(Room length ÷ Floor length) × (Room width ÷ Floor width) = For a room with a floor length of 5m and a width of 4m, use a 750mm × 90mm × 18mm floor as an example:
Room length 5m ÷ 0.75m ≈ 6.67 (block) Take 7 (block)
Room width 4m ÷ 0.09m ≈ 44.44 (block) Take 45 (block)
The number of wooden floors to be purchased: 7 × 45 blocks = 315 blocks When buying, it is necessary to take into account that 8% of the loss is usually found in solid wood floor coverings.
5, curtains Normal curtains are mostly flat curtain, in the calculation of curtain materials, first of all according to the specifications of the window to determine the size of the finished curtain.
The finished curtain should cover 0.15m to the right and left of the window frame and double folds. When installing curtains to be 15-20cm from the ground.
Calculation method:
(Window width + 0.15m × 2) × 2 = Finished curtain width Finished curtain width ÷ Width × Curtain height = Curtain required cloth Assumption Window specifications: width 1.55m, height 1.90m:
Finished curtain width = (1.55m + 0.15m x 2) x 2 = 3.70m
Curtain height = 0.15m + 1.90m + 0.50m + 0.20m (Burma) = 2.75m
Take the cloth width 1.50m as an example:
Need to buy curtain fabric: 3.70m÷1.50m×2.75m=6.78m
6, the coating of paint packaging is basically divided into 5 liters and 15 liters of two specifications.
Taking the 5 litre capacity commonly used in the family as an example, the theoretical brushing area of ​​5 liters is 35 square meters twice.
A rough calculation method:
Floor area x 2.5÷35=accurate calculation method using the number of barrels:
(Room length + room width) × 2 × room height = wall area (including door and window area) Room length × room width = ceiling area
(wall area + ceiling area - door/window area) ÷35 = The number of barrels used is 5m in length, 4m in width, and 2.7m in height. The brushing area of ​​indoor walls and ceilings is calculated as follows:
Wall area: (5m + 4m) × 2 × 2.7m - 48.6m2 (4.5m2 including doors and windows)
Ceiling area: 5m×4m=20m2
Coating amount: (48.6m2+20m2-4.5m2)÷35 m2/bbl = 1.83 barrels. Actually need to purchase 5 liters of paint 2 barrels, the rest can be used as a backup.
The above is only the theoretical amount of brushing, because in the construction process to add appropriate amount of water, so the above amount is only the minimum amount of brushing.

Advantages of Aluminum Doors
Multi-panel door systems are often made with aluminum frames to facilitate indoor/outdoor living. Milgard aluminum frames are available in anodized or baked-on finishes for long lasting color. Sealed, mechanically joined corners stay square and true over years of use.
•Aluminium doors provide stability.
•Aluminum doors are easily available.
•Aluminum doors maintenance is easy.
•Aluminium doors are good choice for houses with modern designs.
•Aluminium doors provide weatherproof qualities.
•Aluminium doors do not rust
Light yet strong, aluminum windows and doors can be configured into a wide variety of combinations. The narrowness of the frame places the focus on the glass and subsequently, the view it offers.
Aluminum is not recommended in beach homes for while the material is water resistant, it can suffer corrosion from salt water and salt air. The corrosion affects hardware operation and frame performance.
Compared with vinyl, fiberglass and wood frames, aluminum conducts heat and cold the least well. To reduce heat flow,Sunsia offers a Thermally Improved Aluminum frame in select regions. Thermally Improved Aluminum windows and doors are equipped with thermal breaks to separate the interior and exterior surfaces and improve energy efficiency.
