Discover the T7003 RPT Series: Airclos Leads the Future of Retractable Roofs.

In the constant quest for excellence and innovation, Airclos is proud to present the latest evolution in our acclaimed retractable roof series: the T7003 RPT Series.

This new model not only inherits the robustness and avant-garde design of its predecessor, the T7000 RPT, but also introduces significant improvements in two crucial aspects for contemporary architecture: watertightness and insulation.

Aware of the challenges presented by both extreme climates and the need for more efficient and comfortable spaces, we have dedicated countless hours of research and development to exceed our customers' expectations. The T7003 RPT Series is the result of this unwavering commitment to innovation, presenting significant advances in several areas that ensure the T7003 RPT Series is not just an improvement over its predecessor, but a true pioneer in the enclosure system industry.

Redefining Excellence: Key Innovations in the T7003 RPT

We will explore each of these improvements in more detail below:

Improvements in Watertightness:

  • Polyamide profile between leaves: We have introduced a polyamide profile at the junction between leaves, achieving a significant improvement in thermal bridge breaking. This profile is secured along its entire length with 3M tape, eliminating any gap between the junction and the leaf where it is installed.
  • Windbreaks in the guides: To prevent air or light infiltration, a windbreak system has been developed that is installed in the guides, specifically at the point where the leaves cross.
  • Front block under the guides: To cover any gap between the guide and the lintel and prevent filtrations, we have designed a front block that is placed under the guides.
  • Watertight tape on the side guides: Now, the side guides are sealed with watertight tape, applied both at the end of the guide and on the side caps, improving watertightness.
  • Foamy sealing gasket at the front: A foamy sealing gasket has been added at the front to optimize watertightness and insulation with the motorized leaf and the front lintel.
  • Improved material in the guide joints: The motorized leaf now incorporates water deflectors, facilitating the evacuation of water to the outside.
  • Guide joints: The material of the guide joints has been updated to maintain thermal bridge breaking at the joint points.

Improvement in Durability:

  • Accessories with more durable finishes: The transmission system accessories now offer options in stainless steel or with cataphoresis finishing, significantly increasing their durability.

Triple Glazing in Airclos Retractable Roofs

As is customary in our high thermal performance series, the T7003 RPT is manufactured with triple glazing, achieving a Ug value of 0.5W/m²K.

The Ug value measures the temperature exchange between the inside and outside of a room through the glass. The lower the Ug value, the less transmission there is, and therefore, less heat or cold loss will occur in the home, increasing comfort while reducing energy consumption and environmental impact.

Given that the majority of the surface area of retractable roofs is glass, this represents a considerable improvement in the thermal performance of the entire roof.

What is Thermal Break?

A thermal break occurs when a specific element (the frame of a window, for example) has a higher U value transmittance than the adjoining elements (the walls). In turn, the heat, which always looks for the easiest escape route, tends to escape through these components.

This occurs mainly when working with highly conductive materials such as aluminium.

The Thermal Break was created precisely to reduce this transmission of temperature between the inner and outer sides of a building. This is achieved by preventing the different sides of the conductive material (aluminium) from coming into contact with each other.

Therefore, a very low conductive material is inserted between both sides.

Advantages of using the Thermal Break:

  • Energy saving: By avoiding temperature transmission, consumption in air conditioning (either hot or cold) is reduced. This allows for more efficient buildings and a reduction in CO2 emissions.
  • Glass condensation reduction: In cold weather, where the external temperature is very low and the relative humidity indoors is high, the phenomenon of condensation occurs on the inner profiles.

Thermal Break in the T7003 RPT

The T7000 RPT marked a milestone as the first series of retractable roofs on the market equipped with effective Thermal Break Technology. The T7003 RPT, for its part, not only takes up the innovative design of its predecessor but also perfects thermal break technology, thus achieving a significant advance in efficiency and thermal performance.

How do we get a U value of 1.4W/m²K?

To achieve this, a longitudinal Thermal Break is created to cover all the points of contact between the indoor and outdoor profile. Let's look at these points in detail:

  • Polyamide inside the leaf profiles: To avoid direct contact between the interior and exterior profiles, we insert a polyamide barrier with low thermal transmittance, ensuring effective separation.
  • Polyurethane Foam (PUR) filling in the profiles: The cavity created by the polyamide inside the profiles is filled with polyurethane foam, which further reduces thermal transmittance.
  • Polyamide between the leaves: In our staggered design, where the leaves partially overlap, we place polyamide on the exterior face of each leaf to prevent direct thermal contact between them. This measure is complemented by the previously mentioned improvement of the polyamide profile and its fixation with 3M tape at the junction between leaves.
  • Polyamide between the guides: Being a system with a staggered design, we introduce polyamide profiles between the different aluminum guides to eliminate direct contact between them, thus extending the Thermal Break to the entire system, not just to the roof leaves. In addition, recent improvements include the update of the material of the guide joints, ensuring the continuity of the Thermal Break at all connection points.

How does polyamide influence thermal insulation?

Traditionally, Thermal Break in aluminium profiles is obtained by inserting polyamide insulating rods reinforced with 25% fibreglass. This material has a conductivity almost 800 times lower than that of aluminium, creating a continuous isolated barrier that prevents heat transmission.

How does Polyurethane Foam (PUR) influence acoustic insulation?

Polyurethane Foam is a synthetic, duroplastic, highly cross-linked, and non-fusible material characterised by its high resistance to thermal and acoustic transmittance.

It has a high insulating capacity due to the low heat conductivity of the foaming gas in the closed cells. This represents a 25% improvement compared to the average of other products used in thermal insulation.

When the installation of a retractable roof with Thermal Break becomes interesting

Taking into account the advantages mentioned above, this system is perfect for:

  • Reducing the U Value, energy loss and, therefore, energy consumption and environmental impact.
  • Attenuating the acoustic impact.

These two premises make this type of enclosure especially suitable for businesses focused on leisure and hospitality.

Pubs, restaurants, hotels and other businesses in this category make large investments to guarantee their clients' comfort (in heating, air conditioning, smoke vents...), which is why looking for solutions that reduce this cost will be highly profitable. In addition, reducing sound for a more comfortable atmosphere is also key in this type of business. That's why our retractable roof from the T7003 RPT series is particularly interesting for these cases.

The same properties must be taken into account for the walls. It makes no sense to install a retractable roof with a thermal break and glass curtains because all the insulation offered by one system is lost in the other.

The best combination as recommended by the brand would be Airclos bi-fold doors with Thermal Break such as the S220 RPT and S200 RPT series.

Other potential applications are indoor patios or indoor pools. In these applications, the system is often completely surrounded by walls which guarantee the enhanced benefits of the glass. In addition, these are usually businesses that generate a lot of noise, so reducing noise transmission is also important, especially in residential areas.
