APPLICATIONS WITH POLIISO® AD
NON-TREADABLE INVERTED ROOF
The inverted roof is the solution to all those problems linked to building traditional flat roofs and it is characterized by the laying of the waterproofing membrane below the thermal insulation layer. When insulating non-treadable flat roofs, extruded polystyrene is normally used for its high compressive strength, almost no water absorption, and high resistance to frost/defrost cycles. Generally, in this type of roofing, there is a layer of washed gravel (16 - 32 mm) laid on top of the insulating layer.
It is used both as finishing and to protect the extruded polystyrene boards against UV rays and wind. The drainage layer is to be laid by starting from the farthest point of access to the roof and covering the entire surface. It is recommended that the drainage layer be at least as thick as the insulating layer and anyhow no less than 5 cm thick.
The weight of the gravel also contrasts the buoyancy of the insulation boards. It is also recommended to lay a separating layer made of non-woven fabric, for instance, as a filter between the extruded polystyrene and gravel. The concrete slab is duly waterproofed and the laying surface is leveled with a roll of expanded polyethylene. The X-FOAM® HBT boards can be laid on the sheathing without any need for adhesives. There is no need for vapor barrier because there is no forming of condensate.
TREADABLE INVERTED ROOF OR FLAT ROOF
In this type of inverted flat roof, like any other inverted roof, the waterproof membrane is laid below the thermal insulation so that the insulating layer can protect the waterproofing and underlying structure over time. This type of roofing is treadable and the finish consists of cement or ceramic tiles laid on mortar. When insulating inverted flat roofs, extruded polystyrene is normally used for its high compressive strength, almost no water absorption, and high resistance to frost/defrost cycles.
Laying : a coating of lightweight mortar with a minimum gradient of 1%is applied on the roof's concrete slab. The waterproofing membrane is laid on the coating. It is then either fastened or welded according to the manufacturer's instructions.
X-FOAM® HBT extruded polystyrene insulation boards are then laid trying the cover the entire surface of the roof. We recommend laying roofing felt (layer of non-woven fabric) of a weight of at least 100 g/m² between the insulation boards and waterproofing layer to avoid the risk that they glue together. Non-woven fabric, preferably white, is laid on the insulating layer followed by a layer of reinforced mortar at least 4 cm thick to ensure better gripping with the finishing tiles.
FLOOR
In floors thermal insulation is laid on the floor and under the flooring. In this type of floor, the insulation needs to bear working loads that are not very large yet are permanent. The insulation is also exposed to possible water vapor condensation: in order to avoid this risk, the floor's surface temperature needs to be not much lower than that of the room's air temperature. For all these reasons, the thermal insulation used for this type of application must have good hygrometric properties and mechanical performance.
Laying : once the concrete slab is cleaned and leveled, the X-FOAM® HBD insulation boards are laid on it covering the entire surface. The boards do not need to be fastened mechanically; all you need to do is lay them on the surface.
The flooring is then laid on the insulating layer by applying adhesive mortar or a slab of at least 4 cm in thickness. In order to complete the floor, a desired coating layer is applied (partitions, slabs or simply treadable screed). Thanks to their near zero capillarity and to the fact that they do not absorb water, X-FOAM® boards do not require any protective layer against water that may be present in the concrete mix or overlapping layers.
RADIANT FLOORS
Good floor thermal insulation ensures a good temperature avoiding cold spots and the forming of surface condensate while saving energy. A very heating type of heating system that is being increasingly used and allows for uniform temperature and major energy savings is the radiant floor. The most convenient thermal carrier is low temperature water (more or less the same temperature of sanitary hot water: 30 - 35 °C) running through heaters by means of special piping.
Low temperatures favor the integration of other heat sources such as heat pumps and water solar collectors; they reduce heat losses in the distribution system, corrosion and scaling in piping, but they require heaters with a large surface covering even the entire treadable surface. One product especially recommended for this type of application is POLIISO® AD. It consists of expanded polyurethane panels coated with embossed aluminum.
Thanks to this special combination of foam and coating, this product offers one of the best thermal conductivity λ available on the market ( λD = 0,022 W/mK). The waterproof support allows the product to achieve a μ value = ∞, that is to say a total barrier to the passage of water vapor. The panel is also characterized by a good mechanical performance.
Laying : the panelsare simply laid dry on the surface and fit together side by side. A sheet of polyethylene is used to protect the insulation when casting the concrete slab. The piping system is then laid and fastened on the separating layer, the concrete slab is cast and the flooring is laid. POLIISO® AD is waterproof. Thanks to the embossed aluminum coating it is resistant to water leaks and water vapor. However, it is good practice to avoid that any debris ends up in the joints between one panel and another.
ADVANTAGES
-Conduction heating. -Pleasant surface temperature. -Easily settable heating system. -More space for furnishing because there are no radiators. -Central heating. -Less heat losses through the distribution system. -High thermal inertia.
CAVITY WALLS INSULATION - POLIISO
Cavity walls consist of two faces with an empty space in between to apply thermal insulation boards or panels. This building technique is widely used across Italy because it ensures a high degree of thermal comfort by keeping the interior walls warm. Walls are usually either curtain walls or load-bearing walls: in the latter case, the outer face often has an at-sight masonry finish (bricks) and protects the load-bearing wall against bad weather while preserving the inner thermal insulation, as the latter is no longer accessible. The advantage of double walls is that the load-bearing wall on the inside accumulates and preserves heat at length.
Wall performance is further improved by creating ventilated air spaces, namely an air barrier between the outer face and inner face on which the insulation boards are applied: air circulation maintains a low concentration of water vapor and provides a further degree of protection for the insulation over time. Air circulation is ensured by means of vents in the outer face and the use of spacers between the outer face and the insulation layer.
POLIISO® PLUS is the best solution for this type of application, since it ensures long-lasting performance, it is a closed-cell product that prevent water from penetrating through the foam and causing the deterioration of the panel's thermal performance (which happens, instead, with open-cell or fiber insulation) and has a μ value = ∞, namely it is a total vapor barrier. Thanks to the aluminum foil layer, the panel affords one of the best thermal conductivity λ available on the market ( λD = 0,022 W/mK), thus allowing you to save on the applied thickness. POLIISO® PLUS also comes in 1200 x 3000-mm panels, thus making laying much faster, since all you need is a single panel to cover the entire height of the wall. The panels are fit together so that there are no interruptions in the material without any risk of thermal bridging. In case of buildings with a load-bearing structure and outer curtain walls, thermal bridging can be easily solved by passing the thermal insulating layer outside the pillars.
