Rincklake van Endert – A Tradition Spanning 12 Generations

In 1681, Johann Dietrich Rincklake founded his carpentry workshop in Münster, Westphalia. It didn’t take long for his high-quality woodwork to gain recognition beyond the region. Even then, the creation of artistic one-of-a-kind pieces became the hallmark of the manufactory.

Today, RvE continues to craft premium products at the highest level of performance: masterfully handcrafted, invisibly secure, and tangibly beautiful.

"It is our mission to carry on our historic legacy—to live it, to shape it, and to use it as the foundation for a fulfilling future. Our goal, now and always, is to achieve the very best. With solid craftsmanship and an unwavering drive for perfection."


– Rudolf Rincklake van Endert

  • Essentially, anyone who wants to protect themselves, their family, or their property. We’re talking about both burglary prevention and personal protection. Even if a break-in doesn’t result in physical harm, it often leaves victims with emotional distress and a lasting sense of insecurity. Windows and doors are the final barrier to keep intruders out—and they protect you when the guard dog, fence, or alarm system fail.
     
    Experts from your local criminal investigation department, as well as we as a certified manufacturer of security elements, are happy to advise you on which resistance classes are suitable for different areas of your property. As part of this, we carry out a thorough on-site inspection to assess the potential risks.
     
    For private homes, the police generally recommend resistance class RC2 to RC3 for windows and doors in accessible areas (within reach or at ground level).
  • RC stands for “Resistance Class” and refers to a classification according to DIN EN 1627ff. The security features of elements are assigned to one of six RC classes. The higher the number, the longer a window or door can withstand an attempted break-in—and the more resistant it is to heavier, more professional tools.
     
    WK stands for “Widerstandsklasse” (Resistance Class in German). However, this term is outdated and has been replaced by the “RC” classification. Correct usage of these terms can also serve as a helpful indicator when looking for a reputable manufacturer of security windows and should not be overlooked.
     
  • When we look at the table of resistance classes, the first noticeable differences are the resistance time and the intruder profile. For RC2, an opportunistic intruder will need at least 3 minutes to attempt a break-in, whereas for RC3, a more experienced intruder will be at work for at least 5 minutes. In fact, the total testing time for RC3 elements in the laboratory is significantly higher!

    The most important difference lies in the tools used: For RC2, the primary tool is a 365 mm screwdriver. For RC3, a 710 mm crowbar (pry bar) is added, allowing the intruder to apply enormous leverage. With such tools, an RC2 element can be forced open relatively quickly. In contrast, an RC3 element is expected to withstand an attack with a screwdriver indefinitely.

    The level of burglary resistance increases exponentially from one RC class to the next. We achieve this through the use of different materials. For RC3, hardwood such as oak is required, whereas for RC2, softwoods like pine, larch, or fir are generally sufficient. Additionally, RC3 elements have significantly more locking points in the perimeter hardware, much stronger anchoring to the masonry, and additional metal reinforcements in the frame.

    The glazing also differs: At RvE, we typically use P4A impact-resistant glazing for RC2 elements. Starting from RC3, we recommend break-in-resistant security glass of class P6B or higher, according to DIN EN 356. Visually, you won’t be able to tell the difference between RC2 and RC3 elements from our manufactory. Even with the thicker glass, we can offer very slim profiles and extremely narrow sightlines.

    We strongly advise against using RC2N elements in accessible areas. The “N” indicates that no security glazing is installed, creating a weak point that an intruder can easily exploit.

  • Wood is a natural, renewable high-tech material with outstanding physical properties that are hard to match. It naturally offers high strength and excellent insulation values in both thermal and acoustic performance. Thanks to its natural oils, wood has antibacterial properties, is breathable, and helps maintain a healthy indoor climate and balanced humidity. Plastic and metal elements simply can’t compete with these advantages!

    We harness these positive characteristics of wood for our security elements. Softwoods like pine or larch are used for RC2 elements, while hardwoods like oak are required for RC3 and above.

    Wood also has significant advantages in the event of a fire: it doesn’t release toxic fumes or corrosive acids that can damage flooring. Unlike plastic components, wooden fire protection elements retain their shape longer during a fire and are less likely to warp, ensuring that escape routes remain unobstructed.

    In general, wooden windows and doors stand out for their exceptional durability. Plastics can become brittle, fade over time, and are difficult to repair. Wood, on the other hand, can be restored and refurbished repeatedly—as evidenced by countless historical and listed buildings.

    Although plastic elements are typically much cheaper to purchase, wooden windows and doors offer significantly greater value and should be seen as a long-term investment. In addition, wood allows for extensive design and customization possibilities. It can be shaped and finished in a variety of ways, enabling us to create not just a standard product but a unique piece tailored to your specifications, including customized surfaces, profiles, and formats.

  • Unfortunately, no. An alarm system offers no mechanical protection against a break-in and should always be used in combination with security windows and doors. While today’s alarm technology is incredibly advanced, professional burglars often have access to the latest tools and technology as well—and can potentially disable even top-of-the-line alarm systems. If that happens and your windows and doors don’t have burglary-resistant features, intruders can break into a house or apartment within seconds and cause significant damage. By the time the police arrive, the perpetrators are often long gone.

    Security elements are the last physical barrier an intruder must overcome. The longer it takes them to get through, the higher the likelihood that they will give up and leave.

  • Not at all. Our team has been working successfully with heritage conservation authorities in Germany and across Europe for many years. Together, we’ve developed special solutions, such as box-type windows with RC3 certification. In these cases, the listed window is either preserved or faithfully reproduced by us—including historic profiles, finishes, and more. To ensure the necessary level of security, we install a secondary security window on the interior side of the box construction. This not only increases protection against burglary but also improves thermal insulation and soundproofing. The outer window maintains the historical appearance, while the inner window meets modern technical standards and enhanced security requirements.

    Working on listed buildings often presents special challenges and unexpected surprises—but as a manufactory, we are well-prepared to handle them with our comprehensive planning expertise and skilled craftsmanship.

  • FB is a classification for bullet-resistant elements according to DIN EN 1522. In Europe, we differentiate between ballistic resistance classes FB1 to FB7. The higher the number, the greater the resistance against attacks with firearms—ranging from handguns and rifles to automatic weapons.

    During a so-called ballistic test, a laboratory evaluates whether the window, as a complete construction, can withstand an attack with a firearm. For example, in an FB4 test, the wooden security window is shot at from a distance of five meters at predefined target points using a Remington Magnum .44 handgun. In our case, the window had to withstand 42 projectiles! These projectiles strike the frame, connection points, and glazing at speeds of 450 m/s and from various angles. The test is only passed if none of the bullets penetrate and no splinters or fragments break loose on the interior side.

    This is why bullet-resistant glass alone is not sufficient. For true protection, the frame, fittings, and glazing must be precisely coordinated. Always make sure that any bullet-resistant elements you choose come with an official FB certificate!

  • NS stands for “non-splintering,” and it’s an important specification not to be underestimated. Glass in this category is especially beneficial if you have children in the home, as it helps protect them from injuries. However, splinter protection is absolutely essential in the field of bullet resistance. If a pane stops a bullet but splinters on the inside, those shards can become potentially life-threatening, razor-sharp projectiles traveling at high speed.

    The “NS” designation can, in some cases, save lives.

  • Security elements with an RC certificate according to DIN EN 1627 have been tested by an independent German institute for their resistance to break-in attempts. The entire element, including professional installation, undergoes a comprehensive three-part test.

    A door or window can only provide reliable burglary resistance if all components meet DIN standards and are perfectly coordinated. During laboratory testing, the institute simulates an actual break-in attempt using tools specified for each RC class. If the element withstands the attack for the required minimum time, it receives certification.

    At RvE, we don’t just have individual standard sizes tested by the PfB in Rosenheim—we carry out what’s called a system test for our RC products. This means we have entire product systems certified in different versions (sizes, shapes, number of sashes, features).

    Be cautious of manufacturer claims like “tested in accordance with” a resistance class. These often mean that only individual security components—such as mushroom-head locking bolts or lockable handles—are used. However, the complete element does not comply with RC certification standards and therefore cannot offer reliable protection.

  • Yes, security elements have a positive effect on energy consumption. The security materials used also offer excellent thermal insulation properties. So, if you are planning an energy-efficient renovation of your property, it makes sense to consider security at the same time. This way, you address both aspects in one step.

  • In our experience, insurers place great importance on security certificates according to DIN standards when it comes to discussing the possibility of adjusting insurance premiums. However, this varies from one insurer to another and depends on the individual circumstances of each property owner. You should definitely check with your insurance provider in advance to understand their specific requirements before choosing a manufacturer.

  • There are various options available. With construction or renovation measures, you can secure your property while simultaneously reducing energy consumption, potentially qualifying for funding from the BAFA. The state-owned KfW Bank offers funding for security measures combined with energy-efficient renovations, including grants and loans for elements starting from resistance class RC2. Additionally, there are regional and local grants for burglary protection—tax deductions and adjusted insurance rates may also be possible, depending on your personal situation and investment volume. This process can be complex, and it's not always cost-effective. We recommend thoroughly researching your options in advance, such as through the K-Einbruch initiative.
