The maritime world demands robust and reliable components, and windows, or portholes as they're often called, are no exception. While traditionally associated with circular shapes, rectangular portholes, or *fenêtre hublot rectangulaire*, are gaining popularity due to their versatility and aesthetic appeal. This article explores the specific characteristics of a 400x200mm rectangular porthole, highlighting its features, applications, and the advantages of choosing a French-made, UV-resistant, tempered glass model with a 4mm opening. We'll also delve into the broader market of opening portholes, focusing on price, quality, and availability.
Understanding the Specifications: 400x200mm Rectangular Porthole
The 400x200mm dimensions represent a common size for rectangular portholes, suitable for a range of marine applications. This size offers a good balance between providing ample natural light and maintaining structural integrity. The key specifications of this particular model – a 4mm opening, tempered glass, and UV resistance – are crucial for its performance and longevity. Let's examine each in detail:
* 4mm Opening Mechanism: The 4mm opening mechanism refers to the operational clearance of the window. This precise dimension is critical for the smooth and reliable operation of the opening mechanism, ensuring a tight seal when closed and easy access to ventilation when open. A precise manufacturing process is necessary to achieve this level of accuracy. The smaller opening also contributes to enhanced security and weather resistance.
* Tempered Glass: Tempered glass is significantly stronger than standard annealed glass. This is paramount in a marine environment, where the porthole is subjected to constant stresses from waves, wind, and potential impacts. Tempered glass is designed to shatter into small, relatively harmless pieces upon breakage, reducing the risk of injury compared to sharp shards from annealed glass. Its robustness ensures the long-term durability and safety of the porthole.
* UV Resistance: Ultraviolet (UV) radiation from the sun can degrade materials over time, leading to fading, cracking, and weakening. The UV resistance of the glass is crucial for maintaining the structural integrity and aesthetic appeal of the porthole. UV-resistant glass helps prevent the discoloration and deterioration of the surrounding materials, extending the lifespan of the entire installation. This feature is particularly important for boats and yachts that spend extended periods exposed to sunlight.
Fenêtre Hublot Ouvrant au Meilleur Prix: The Quest for Value
The market for opening portholes is competitive, with a wide range of options available at varying price points. Finding the *fenêtre hublot ouvrant au meilleur prix* (opening porthole at the best price) requires careful consideration of several factors:
* Material Quality: While price is a significant consideration, compromising on material quality can lead to costly repairs or replacements down the line. Investing in high-quality tempered glass and a robust frame is crucial for long-term value.
* Manufacturing Standards: Portholes manufactured to high standards will offer superior performance and longevity. Look for manufacturers with a proven track record and adherence to industry regulations.
* Features and Specifications: The specific features of the porthole, such as the opening mechanism, sealing system, and UV resistance, directly impact its performance and lifespan. Prioritize features that align with your specific needs and environmental conditions.
* Warranty and Customer Support: A reputable manufacturer will offer a warranty on their products and provide excellent customer support. This is invaluable in case of any issues or defects.
