THE THERMAL INSULATION SYSTEM FOR ROOFS
Isotec is a thermal insulation system for roofs designed specifically to repair and recover roofs in old buildings or to create new roof coverings.
The correct installation is sped up by the lightness, easy maneuverability and workability of the panels which are laid in a sequence (from the gutter to the ridge of the flashing) to quickly form a load-bearing deck that is thermo-insulating, microventilated/ventilated and impervious to accidental infiltrations in the roof covering.
The installation of Isotec requires compliance with a few simple rules and the strict use of accessories, which are provided in the kit of the system. When installed correctly the roof is no longer a problem, and becomes a real source of living comfort and energy saving throughout the entire building.
1. The transverse ends of the panels are cut in a dovetail fashion to ensure continuity of the insulation.
2. The Isotec panel is shaped with opposing battents that ensure it wedges snugly between the panels, eliminating the risk of thermal bridges.
3. The panel is made load-bearing by a steel stiffener with water-drip ribbing protected by an aluminium-zinc-silicon alloy, perforated, with a height of 30 mm.
4. The Isotec panel is made of self-extinguishing rigid polyurethane foam.
5. The Isotec panel is covered on both surfaces by embossed aluminium foil.
VENTILATED INSULATED ROOF
The Isotec thermal insulation system is designed to be applied on all pitched roofs, with any type of supporting structure. It ensures thermal insulation, under-tile ventilation, second-stage waterproofing and, thanks to the metal stiffener, acts as a substructure for securing and hooking the roof covering. It can also be used to repair old roofs or create new ones.
Some examples of the application of the Isotec system on different types of supporting structures:
CONTINUOUS WOOD STRUCTURE
CONTINUOUS CONCRETE STRUCTURE
DISCONTINUOUS STEEL OR WOOD STRUCTURES
DISCONTINUOUS STRUCTURE ON WALLS
ISOTEC can be combined with all types of roof coverings, the pitch varies depending on the cladding chosen.
ISOTEC INSTALLATION: SIMPLICITY AND SPEED
• Fixing of the wooden stop bar (the same thickness as the panel) and the first Isotec panel with reduced pitch. Fix the Isotec panel to the supporting structure by means of a mechanical fixing system to be defined according to the support (screw anchors, anchor bolts or self-tapping screws).
• Continue with the subsequent rows following the same sequence, until arriving at the ridge of the flashing. The cut parts of the panel can be reused for the next rows.
• This procedure for subsequent rows from the gutter to the ridge reduces the percentage of waste material by an average of about 3%.
• Fix the under-ridge brackets to the flat part of the metal stiffener and lay the under-ridge plate
• It is a good idea to use a ventilated gutter batten along the gutter line that not only prevents birds from getting inside, but also ensures continuity of the slope when laying the first row of tiles on the gutter line.
