  • Detalles constructivos, puntos singulares, etc.

BorjaSAT es una solución técnica para la instalación y aislamiento por el exterior de cubiertas inclinadas, evitando puentes térmicos. Esto se consigue gracias a los paneles λSAT, fabricados por moldeo con poliestireno tipo Neopor ®. Los paneles llevan preparados los espacios donde se deben acoplar en obra los rastreles metálicos del sistema, que quedan encajados y fijados sobre los propios salientes que presenta el panel λSAT.

El mismo panel se fabrica en varios espesores de aislamiento, y es válido para todas las tejas cerámicas de la marca, porque funciona en dos distintos pasos de rastrel (370 mm y 395 mm), según se instalen los paneles en posición horizontal o vertical sobre la cubierta, que debe ser continua y estar previamente nivelada.

Tejas Borja confía con este nuevo hito que la certificación DIT Plus refuerce aún más la confianza del mercado en su gama de productos y sistemas, y así seguir colaborando con sus clientes y socios, así como dando apoyo a técnicos y prescriptores en sus proyectos y obras, para crear un entorno más seguro, sostenible e innovador.

About the use old recovery roof tiles

Tejas – Roof tiles – Tuiles

¿Are the old roof tiles reusable? Do they have any warranty??

Usually in old building we can find old roof tiles, basically Arab-style roofing tiles or Marseille roof tiles, that were originally handmade produced by smallold local “potters” so there is no guarantee to be used in a new deck or for a roof rehabilitation. According with the new mandatory CTE (Código Técnico de la Edificación / Technical Building Code) is mentioned for the supply of any construction material on site, the following:

“7.2.1. Control of documentation of supplies

1. The product suppliers must provide documentation and quality guarantees required for the products supplied. The suppliers will deliver to the builder, who will provide to the manager on site, all product identification documents required by the mandatory regulations. This documentation shall include, at least, the following documents:
a) Documents of origin, supply sheet and labeling;
b) The manufacturer’s guarantee certificate, signed by a natural person; and
c) lThe documents of conformity or administrative authorizations required by regulation, including documentation corresponding to the CE marking of construction products…”.

If we cannot find the manufacturer of the old mentioned roof tiles and there is no documentation for them, there will be no warranty and can be used only for decorative purposes and not to fulfill the functions for which the roof tiles are inicially made (covering and protection against rainwater and winds.)

Did you know…?

Tejas Borja has been manufacturing Plana Alicantina, a flat roof tile format, Marseille type, since 3 generations. This makes it, a product suitable for replacement that fits in installation with similar old roof tiles, produced by different manufacturers.

…The Aged roof tiles finishes of Tejas Borja have been created by investigating how the roofs age in different geografic areas.

…The textures on the roof tiles that are represented in Centenaria range have been inspired by the millennial technique of the handmade manufacture of roof tiles. Faithfully reproducing the hands and fingers marking on the roofing tile, Centenaria is a reference in the industry.

BORJASYSTEM – Ventilated Efficient Roofs System

BORJASYSTEM

Ventilated Efficient Roofs System

BORJASYSTEM is a dry, ventilated and safe installation roofing system. This installation system was born under the necessity of adapting to new requirements with regards to the need of reducing energy consumption, and CO2 and greenhouse gas emissions to meet Horizon 2020 energy objectives.

BORJASYSTEM ventilated roof, installed together with the corresponding layer of thermal insulation, improves the energy efficiency of the roof, playing an important role in reducing the heat which passes through the covering to inside the home.

BORJASYSTEM Sistema de Instalación de Tejados Ventilados de Teja Curva

This roofing system minimizes the chances of condensation forming in the thermal insulation and the materials of the exterior walls and roof, thanks to the use of waterproof and breathable membranes and the continuous circulation of air between the supporting structure and the tiles. The incorrect use of mortar causes the majority of problems experienced with sloping ceramic tile roofs:

  • Damp and leaks.
  • Structural overloading.
  • Cracks and breaks in parts and joints.
  • Lack of adequate ventilation.

The BORJASYSTEM installation system defines the criteria to be followed for a complete dry installation of the roof without the use of mortar. When it comes to roofing, the correct installation of the system is as or more important than the material used to finish it.

The ventilation of the roof

La-ventilacion-de-un-tejado

What should be consider regarding the ventilation of the roof?

Adequate ventilation of the roof, unthinkably, is an aspect not often considered when building a house, although it is an important factor that strongly determines its durability and efficiency.
Having this matter into consideration during construction stage will save expensive repairs in the future and will make the cost look insignificant.

As known, ceramic roof tiles are porous products and therefore susceptible to absorb and release water (known as “breath” of the material), that makes them ideal to regulate the moisture inside the building.

How to avoid moisture through the roof in a house?

For a good ventilation of the deck consider:

  • ensuring a good setting of the roof with special attention on the minimum air chamber
  • using Accessories and Roof components
  • using Ventilation roof tiles displayed in a proper array

This permits an easy drying of the roof tiles and eliminates moisture build-up inside the roof.

The roof ventilation will improve the conservation, thereby enhancing the maintenance of the roof. It also reduces the appearance of mosses and fungi, since a well-ventilated roof tile retains the water absorbed for a lot less time and therefore fails to provide moisture conditions that favour germination.

Why is it so important the roof ventilation?

Even if a roof is properly done, the humidity will have access inside. This is a phenomenon always present and technically unavoidable; therefore, the system used for the entire roof must provide a way for the condensed water to be removed from the inner layers of the roof.

Thus, ventilation becomes the key element for that purpose, which is achieved by providing a chamber beneath the roof tiles to force airflow re-cycle through for a continuous drying process.

WHY DRY INSTALLATION?

The fitting process of clay roof tiles is very important and it should considered at the time of choosing the material to be used on the roof.

Dry installation has significant advantages over conventional installation, as well as improving the performance of the roof during both summer and winter.

To ensure that the roof is installed correctly, air must circulate continuously in the space under the roof tiles. This micro-ventilation will allow air to enter via the eave lines and leave through the ridge lines, increasing through the use of ventilation roof tiles distributed along the roof.

During the summer, this air chamber will reduce the amount of heat received by the support for the roof tile and, therefore, the heat transferred into the building, reducing air conditioning costs.

In winter, indoor ventilation will prevent condensation from forming on the materials used to build up the roof (roof tiles, insulation, support, etc.), as they harm their durability. Furthermore, this condensation can affect the comfort of the building, producing moisture that is conducive to the formation of moss and bacteria that reduce the quality of the air inside.

With regards fittings, the use of mortar is not recommended due to its poor reaction with ceramics and the rigidity of joints. Roof tiles should be fixed mechanically or with adhesives made specifically for roof tiles, since these give the materials the necessary room to allow for the movements caused by expansion and changes in temperature.

To ensure their optimal installation, the Roof Tiles should be fixed to a support previously prepared with a double batten layout. Tejas Borja has a wide range of clay accessories and roof components as a solution for the ventilation, waterproofing, illumination and dry installation of roof tiles.
