Good vintage for the sale of windows in France
More than 10 million windows were sold in 2017, after 4 difficult years. The decrease in the amount of the Cite and its end at the end of June may be for something. According to the UFME federation, sales rose 6% in 2017.
This level is similar to that of 2011-2012. But still far from the record of 2008 to 12.5 million windows.
Concern, however, points to whether the windows will be eligible for the energy check. Ademe and CSTB must make public a report on the 25% energy saving claimed by the profession.
The 10 million windows are 60% for PVC, 30% for aluminum and 10% for wood. And almost 70% come from the renovation market.
Countersinks for flat glass
After drilling it may happen that the periphery of the hole there are some scratches or that this hole is intended to let a screw to fix the glazing and that it is desired to house the head of the screw inside the glass.
In this case we will mill the glass around the hole, either to remove the scratches (case glass for tempering) or to create a cavity to accommodate the screw head.
The diamond tool used is a countersink. It is a diamond cone, the diamond part making an angle of 45 ° with respect to the axis of the tool.
How to choose the right tool because there are several?
There are several types, adjustable or not, continuous diamond crown or segmented diamond crown.
Adjustable or not.
In the case of adjustable countersinkss it is a truncated-shaped tool that is mounted directly on the body of the drill and that is blocked by a screw at the desired height. Each countersink of this type can only be used with one drill diameter.
This type of tool is used when all holes for a certain drilling diameter must be milled, the drilling and milling operation being done without changing tools on the drill. For this type of tool it is important to check with your supplier that the rotation speed of your drill is the same as for milling.
In the case of non-adjustable countersinks it is a diamond cone (or in some cases also a truncated cone). Choosing the right tool is based on the range of hole diameters for which you want to use it. Watering is done in this case as for a classic core drill, by the inside and outside of the diamond tool.
Diamond crown continues or not?
The parameter to take into account in this case is the depth of the milling. A continuous diamond countersink is capable of removing up to 2 mm of glass. A countersink with a segmented crown can remove up to 5 mm of glass.
Possibility also in this case to have adjustable countersink or not.
