A guide to choosing"},"content":{"rendered":"

In the context of the “Energy Performance of Buildings Directive” (EPBD)<\/strong>, the choice of a glass closure system is no longer a mere aesthetic detail, but a structural decision that directly impacts the overall thermal transmittance of the building and, consequently, its energy class.<\/p>\n

<\/p>\n\n\n

To understand how to increase a property’s value, it is important to understand the differences between folding systems<\/strong> (stackable) and sliding systems<\/strong>: two technologies designed to meet diametrically opposite architectural needs.<\/p>\n\n\n\n

Folding Systems: dissolving physical boundaries<\/h2>\n\n\n\n

Sunroom folding glass walls, such as the S.60 TT<\/strong> and S.75 TT<\/strong> models, are designed to ensure an almost total opening of up to 95%.<\/p>\n\n\n\n

Thanks to a lateral accordion-style stacking system, the space occupied by the gathered panels is reduced to approximately 10% of the total length, eliminating every visual and physical barrier between indoor and outdoor spaces.<\/p>\n\n\n\n

This technology is ideal for those seeking absolute flexibility. On a 5-meter opening, the stacked panels occupy only 50 cm.<\/p>\n\n\n\n

In addition to flexibility, there is top-tier engineering solidity. Unlike budget solutions, Sunroom transfers all the weight onto the lower track, avoiding structural bending of the ceiling and ensuring constant smoothness of movement over time.<\/p>\n\n\n\n

Thermal performance is also significant. The S.75 TT<\/a><\/strong> model achieves Uw<\/sub><\/strong> transmittance values as low as 1.0 W\/m\u00b2K<\/strong>, making it suitable even for the harshest climates.<\/p>\n\n\n\n

Sliding Systems: large dimensions and total brightness<\/h2>\n\n\n\n

If the goal is to maximize the view even when the glass is closed, sliding systems are the preferred choice. Sunroom technology allows for exceptionally large panels, covering architectural spans exceeding 6 meters.<\/p>\n\n\n\n

The S.150 TT<\/a><\/strong> system is an industry benchmark characterized by:<\/p>\n\n\n\n
