Isotec Roofing System The ISOTEC panel is a component material which includes in a single product a complex system of elements and functional layers to increase the thermometric and hygrometric performance of a roof. For pdf file Click here

What is it? The ISOTEC panel is an insulation and structural panel which is perfect for new roofs and for redoing old ones. The ISOTEC panel consists of a flameproof insulating core made of rigid polyurethane foam covered in waterproof embossed aluminum with a supporting metal structure. Holes in the panel channel any leaks by the top roofing layer right into the eaves and ensure a perfectly ventilated roof. The ISOTEC panel is interlocking, thus providing an excellent fit which eliminates thermal changes.   For pdf file Click here

What does it Guarantee?

Protect from leaks by the top roofing layer.

Provides a rational solution for the vapour barrier.

Ensures effective ventilation for the lower roofing layer.

Offers ideal support and foundation for the outer roof definitiva.

Provides a safe foothold for fast, easy roofing work. A correctly installed ISOTEC system can be walked on. In case of discontinuous structures, the person walking on the structure must be careful to walk on the metal section and never step on the areas where the panels are joined together vertically, since they cannot support weight.

How it is sold? -

ISOTEC is supplied in standard panels of the following dimensions: length: 390 cm width: 34.2 cm thickness: 6, 8, 10, 12 cm respectively Panels from 23 cm to 69 cm in width can be supplied upon request. When ordering it is necessary to specify the distance of the metal sections according to the roofing tile to be used.     For pdf file Click here

How it is installed?

Installation sequence Protruding elements of the roof such as chimneys, vents, dormers, windows, roof windows, etc., must be connected to the ISOTEC panel by using ISOTEC polyurethane foam covered with ISOTEC tarred aluminum tape. The protection must include an upside-down "V " on top of the element. For Laying instructions Click here

Equipment and accessories The ISOTEC system is extremely simple. It can be installed with ordinary tools such as a hammer, drill, wrench, rip-saw, a disc saw and a extruder for silicone and, to complete the installation, sealing and attachment accessories. For Sealing pdf Click here

Cutting the panels The panels can be cut in one step with a disc saw or in two steps using a rip saw with a rigid blade to cut the foam section. Once the panel is cut to the correct size, it can be laid down and attached. For Cutting pdf Click here

Starting from the eaves First a wood beam (6x6 or 8.5x8.5 cm) is laid to fix the first ISOTEC panel at the edge of the eaves. The beam also serves as the first point to block the gutter. The size of the eaves panel must correspond to the first layer of tiles to be placed in the gutter (5-6 cm). Once this has been done, the panels are laid in successive rows upward to the ridge, staggering the interlocking joints of the panels. For pdf file Click here

Attaching the panels The panels are attached directly on:   Wooden structure. Metal structure. Cement.   On the average, four fastenings per square meter are necessary. The fastening must be done in the rear part of the metal section.   For pdf file Click here

Sealing the joints The side joints of the ISOTEC panels are dovetailed and must be sealed with ISOTEC single-component silicone before they are interlocked. As soon as they have been laid and attached, the surface of the joint must be waterproofed using the appropriate tarred aluminum tape. This ensures the effectiveness of the ISOTEC system, even in case of leaks caused when tiles break or are moved. For pdf file Click here

At the Ridge Near the ridge the pitch must be completed using the portion of a panel equipped with a section or with an entire panel which has been cut to the right size. If there is no section at the ridge a special metal section can be used. For pdf file Click here

The ventilation of the ridge The elements along the ridge can never be attached with mortar because the air beneath, which naturally exits at this point, would be blocked. Laying the ridge elements correctly ensures that they are fixed mechanically, using appropriate brackets, to the lenght of wood beneath. A special sheet beneath the ridge with small holes can be used to control leaks from the side. This mechanically blocks the ridges and allows air to circulate, avoiding leaks.

Compluvia and Hips At compluvia and hips, fix any irregular edges with ISOTEC polyurethane foam and protect with ISOTEC aluminum and tar sheath. Then apply tin trimming to match the top roofing layer. Incompatible metals should be separated with sheath. For pdf file Click here

Side Pitch Near the side pitch a portion of the upper part of the metal covering must be cut off so that metal flashings can be installed. The ISOTEC panel is attached to a wood beam which supports and protects it and is used to attach the metal flashing. Before positioning the flashings it is useful to place ISOTEC tarred aluminum tape between the panels and the wood beam in order to avoid leaks between interlocked elements. For pdf file Click here

Roof Elements Protruding elements of the roof such as chimneys, vents, dormers, windows, roof windows, etc., must be connected to the ISOTEC panel by using ISOTEC polyurethane foam covered with ISOTEC tarred aluminum tape. The protection must include an upside-down "V " on top of the element. For pdf file Click here For Photo Galery click on the Icon
