El espesor del panel será de 20mm para conductos instalados en el interior y de 30mm para conductos a la intemperie o de gran tamaño.
La espuma PIR debe tener una densidad media de ±35 kg/m3 y cumplir con los requisitos de aislamiento del RITE (Reglamento de Instalaciones Térmicas en los Edificios).
Todos los materiales utilizados y los conductos terminados deben cumplir con las exigencias del RITE y con la norma europea EN 13403 para “Conductos no metálicos” y otras EN de referencia en ella mencionadas.
Los conductos serán construidos con base a los Protocolos y manuales de trabajo facilitados por el fabricante. Por lo tanto, hacen parte de esta especificación los requerimientos dados por los reglamentos, normas y recomendaciones aquí mencionadas.
Documentación y gestión de calidad
Antes de iniciar los trabajos, el contratista deberá aportar todos los ensayos y certificados requeridos en la norma EN 13403 y en especial los certificados de reacción al fuego europeo EN 13501-1 (Euroclase B-s1,d0) y/o americano ASTM E84-15 (Class A FD/SD ≤25/50). Al finalizar los trabajos el contratista deberá aportar los formularios cumplimentados de los Protocolos de trabajo. Protocolos y Manuales facilitados por el fabricante serán aceptados como “Documentos Reconocidos” por el RITE.
Mano de obra
El contratista deberá acreditar el grado de capacitación y conocimiento que tiene el personal acerca de la fabricación de los conductos mediante un certificado de capacitación expedido por el fabricante. Para garantizar la calidad de los conductos, el equipo de herramientas utilizadas serán las facilitadas por el fabricante.
Armado y Sellado
Los conductos y las figuras se armarán con cuatro caras separadas biseladas longitudinalmente a 45° y se unirán usando pegamento adecuado. Las uniones longitudinales internas se sellarán con silicona adecuada hasta donde sea posible y en las externas se aplicará opcionalmente cinta de aluminio (obligatorio en los conductos instalados a la intemperie). Las uniones transversales entre las diferentes secciones de conductos se realizarán con el sistema de macho y hembra sellados con cinta de aluminio por el exterior. La cinta de aluminio deberá ser del mismo aluminio gofrado 60mµ que el de los paneles y la anchura mínima debe ser de 75mm (3”) e irá adherida con el mismo pegamento usado para el armado. Todos los insumos no originales utilizados deben ser consultados y aprobados por el fabricante. El procedimiento debe ser de acuerdo con los Protocolos y las recomendaciones facilitadas por el fabricante.
Refuerzos
Los conductos de suministro y/o de retorno deberán reforzarse internamente para soportar la presión de positiva y/o negativa de su funcionamiento y se deberá verificar su posicionamiento, intervalos y cantidad en función a la relación entre dimensión y presión.
Soportes, deflectores, puertas de inspección, pasos de muros, conexiones a unidades manejadoras, accesorios y restricciones.
Todos estos elementos deben ser instalados de acuerdo con el RITE y la norma europea EN 13403 y serán aplicados en base a los Protocolos y las recomendaciones facilitadas por el fabricante.
Conductos a la intemperie
Los conductos instalados a la intemperie serán de 30mm de espesor y la espuma PIR debe tener una densidad media de ±35 kg/m3 y cumplir así con el RITE. El aluminio gofrado de 60mµ de espesor en cada cara y con certificado de no proliferación microbiana.
Los conductos deberán ser lo más cuadrados posibles a fin evitar la acumulación de agua en la cara superior. Los conductos de anchura >120cm (48”) se dividirán en dos conductos para favorecer la resistencia mecánica. Independientemente de la presión de trabajo positiva o negativa, los conductos se reforzarán por el interior. Los tubos internos de refuerzo central se colocarán en posición vertical y se cortarán con una longitud de >1,5cm de la medida de la altura interior del conducto, para forzar la deformación en el centro del conducto de la cara superior hacia arriba y ayudar a escurrir el agua hacia los lados del conducto evitando la deformación y el deterioro por el peso del agua.
El armado de los conductos será el mismo que el aplicado para los conductos de 20mm instalados en el interior de los edificios y serán construidos en base a los Protocolos y recomendaciones facilitadas por el fabricante.
En aplicación del RITE, los conductos en el exterior deberán tener una protección adicional. Esta protección debe ser de pintura de base caucho impermeabilizante tipo “Sikafill” o “Sikafill 200 Fibras” de tres capas que se aplicará una vez terminados los trabajos de instalación de los conductos y evitar así cualquier filtración de agua hacia el interior de los conductos y del edificio.

| Description Characteristics | Galvanized Insulated Ductwork | PIRALU Pre-Insulated Duct System |
| Production | Sheet metal and Insulation materials plus glues and fastening accessories | Single source |
| Fabrication contamination | Fiberglass insulation dispersion during cutting may cause health problems. | No such dispersion as the material does not disintegrate while cutting. |
| IAQ compliance | In a warm and humid environment, wet fiber plus lagging adhesives used in insulation work give rise to eventual growth of fungus, bacteria, mildew (typical ‘black spots”). | Meets the requirement of IAQ (Indoor Air Quality) as per ASHRAE 62-1989 regulations, especially important in clean room applications such as hospitals, laboratories, food processing etc., public places such as malls and community centers. |
| Duct construction | Numerous vendors and components are required. Plus large on site fabrication requires bulky and expensive equipment and fabrication space. Plus additional time and materials for insulation. | Single Vendor and simple on site fabrication, can be done by one person with hand tools. Pre insulated duct boards save time and guarantee better thermal break control. |
| Weight | Galvanized sheets and specially the finished product is heavy, and usually requires a few persons for its transportation and installation. The heavier load requires more supports, and places a heavier tall on the building structure. | Light Weight (15%-20% of GI Ductworks). Less man power / Less fabrication time = $ savings Less weight = less man power / less possibility of accidents / less supports / less structural requirements |
| Heat Transfer | l= 0.038 (with 25mm thick insulation) | l = 0.023 w/mk Due to reduced losses, 18% energy savings over insulated GI ductwork |
| Fire codes | Class ‘O’, BS 476, part 6& 7. | Class ‘O’, BS 476, conforms to Building Regulations 1991. Tested and approved in most countries worldwide. ASTM E84 approved |
| Permeability, Solubility | Slightest damage to the aluminum foil vapor barrier causes condensation on duct surface, which will corrode ductwork and consequential damages to the building ceilings and structure. Fiberglass absorbs water and looses thermal properties. Damp and wet areas are susceptible to mildew and fungal growth. | Closed cell construction reduces water absorption to less than 5% in 24 hrs. of immersion. Slight site damages usually do not compromise the vapor barrier |
| Productivity | The cost of materials – metal and insulation – for typical low pressure air systems, in most (not all) markets tends to be 5-10% less than the pre-insulated panels. But the average waste is 10-15% in material | The FINAL installed cost of the same size of ductwork in pre-insulated material is approximately 20% – 25% less And the average waste is 3-5% |
| Mechanical Protection | In Outdoor systems most ductwork installation require an additional Mechanical protection, which is usually an aluminum cladding. | Pre-insulated panels already bring an aluminum cladding for protection and additional structural strength. |
| Exterior Painting | Usually a base primer is needed on canvas cladding. | Application of paint can be directly applied on panels due to its lacquered surface, which serves as base primer. |
| Reinforcements | Large duct cross sections require angle bracing at close intervals to avoid sagging due to weight of sheet metal and its insulation. | Not required for most common sizes; only extra-large sizes are recommended with stiffeners. A 20 mm thick panel will handle 50 Pa or 2” Wg |
