Summary for decision-makers

The house near Reims was equipped with an old wooden glass door that was not very secure and did not provide sufficient insulation, making it unsuitable for a rural setting with frequent truck and tractor traffic. To improve security and comfort, the owners opted to install a Diamant Luminance II A2P BP1 certified glass security door, recommended and installed by Antivol, a local specialist for 40 years.

The new door offers 42 dB sound reduction, high-performance thermal insulation (Ud 1,7W/m2.K), and a 5-point lock certified A2P* burglar-proof. Its VTX European round cylinder offers enhanced resistance, complemented by patented keys with a unique impression. The custom installation, completed in two hours, provides greater security, peace of mind, and natural light thanks to the Mikado triple glazing.

The owners of a house located in the Reims region chose the Diamant Luminance II glass security door from Picard Serrures to improve the security and insulation of their home, without sacrificing brightness or design.

Installation of a glass security door to enhance the security and comfort of a country house near Reims

Located in the countryside a few kilometers from Reims on a street often visited by trucks and tractors during harvest time, this house had a wooden, glazed door 45-50 mm thick. Equipped with a roller lock with 3 locking points, two of which acted more as compression points, its burglar-proofing, as well as its thermal and sound insulation, left something to be desired, to say the least. This is why the owners wanted, in addition to a better level of security, to find some peace and quiet.

A security specialist operating in the Champagne region for over 40 years, Antivol then recommended the Diamant Luminance II A2P BP1 certified glass armoured door, which had just been launched by the French manufacturer Picard Serrures, a leading name in the residential security market. Thanks to its numerous technical features providing flawless protection and its double frame with thermal break, it met all of their expectations (acoustic attenuation of 42 dB, Ud of 1,7W/m2.K).

Equipped with a lock with 5 locking bolts of 22 mm in diameter certified A2P* burglar-proof by the CNPP(1), the Diamant Luminance II armored door is equipped with a VTX European round cylinder which ensures maximum protection against attempts to open by drilling, sawing, picking, tearing or bumping. In addition, its patented high-security keys, supplied with a numbered property card, whose "wave" shaped imprint provides additional security against picking attempts.

Custom-made in 930 mm width and 2100 mm height, in anthracite gray on the outside and cream white for the inside panel, the Diamant Luminance II was installed after completely removing the old door. It took just over two hours for a team of two people from Antivol to carry out this operation and install the new model. A task that generally requires a day for a house entrance " underlines Romain Michaëli, Business Manager – Locksmith Manager at the company Antivol, Approved Picard Locks Installer for 15 years.

From an aesthetic point of view, the owners chose Mikado full-height, burglar-proof central triple glazing, which allows maximum light to enter. Delighted with the final result, which enhances the facade of their home, they now benefit from optimal security and much-appreciated thermal and acoustic comfort.
