Metal support for PVC joinery, anti intrusion roof is a very important detail on the window. If properly installed, such metal support will guarantee qualitative closing, ventilation and protect from burglary. One of the anti-intrusion details of the window metal support is a type of “briar” placed on some parts of the support. If those briars are of T letter shape, than such support is considered to be anti-intrusion type, but the level of protection depends on number of briars, type of installation, etc. A difference between ordinary and anti-intrusion metal support is given on pictures bellow

However, in most of cases burglar attack a part of the window around hinge, from the outer side. This can be prevented if we place screws that would hold both sides of steel strengthening and will block the opening. Still, burglars can always break the glass and that is why we recommend other types of protection as well as their combining in order to keep the building safe as possible. |

It is important to install additional extension of the metal support onto scissors for opening, so it would close the space between two hinges and also will close the bottom of the window up to 850 mm length. With a two-wing window, it is necessary to install middle auxiliary hinge on the auxiliary wing between two hinges which is actually hidden in the metal support slot. |

There are many other significant details for PVC joinery, but their installation affects the price. That is why we often meet customer saying ”Another firm offers white PVC window, but much cheaper..”, but at this point they do not think much about what they are getting for their money, and what they really need. Proper anti-intrusion protection is very important and many customers start to think about that when it is already late-after the burglary. |
