DOP (DECLARATION OF PERFORMANCE) CLAIMS.

How to be sure to get a guaranteed high-performance door into your home? The EN 14351-1 standard obliges manufacturers of exterior pedestrian doors to put the CE mark on the product. This standard is an extra guarantee, because it includes several regulations that involve testing and grading products by analyzing different performances, so you can be sure to choose the best.

As of July 2013, all CE-marked construction products must have an additional document called Declaration of Performance: DoP (Declaration on Performance).
The DoP collects all essential information related to the product and its traceability and highlights its performance including:

• Air permeability
• Water tightness
• Wind load resistance
• Sound reduction
• Thermal transmittance
• Burglar-proof

The door to be classified in the burglar-proof classes undergoes several tests. Let’s take a close look at them:

An attempt is made to open/break the various components by applying a static load with mechanical pistons at specific points. If, during the pushing, no useful space is created for the passage of a specific gauge, the test is passed.

In this case, an attempt is made to open/break the various components by applying a dynamic load to examine the stability against the pushing blow. The test is passed only if no gap is created after the thrust that would allow a person to pass through.

In this case, an attempt is made to open/break the various components by applying a dynamic load to examine the stability against the pushing blow. The test is passed only if no gap is created after the thrust that would allow a person to pass through.

Following the operator’s attempt to open it manually, an assessment is made as to whether the door is able to resist. The last test, depending on the strength and experience of the operator, is the least objective of the 3.

Thermal and acoustic insulation

Your energy and economic savings will increase with effective insulation.

Synergy In is designed with a thermal transmittance value of 1.4W/(m2 x K). The frame gasket, double cold-shielding foil and no-air plugs increase the level of thermal insulation and at the same time allow for a sound reduction value of 45 dB. Your home will thus always have optimal temperatures and be protected from the intrusion of annoying noise.

Break-in resistance

Dierre is a world leader in security locks; in fact, Synergy In doors, thanks to sophisticated anti-intrusion solutions, have a Class 3 burglar-resistant certificate and, on request, Class 4. Shild drawn steel rostrums prevent the door leaf from being unhinged, plus you can insert the D-Fendy defender that increases the level of protection of the lock to increase your level of security.

Fire resistance

Synergy In can be made to preserve, in the event of a fire, certain characteristics for a set time and block flames by limiting temperatures on the side not in direct contact with fire, thus on the cooler side.

That’s why if you choose Dierre’s security doors, your level of security will only increase!
