THERMAL INSULATION
THERMAL INSULATION FOR HOT FLAT ROOFS UNDER SYNTHETIC MEMBRANE
Roof / Hot Roof
The "hot roof" type is made with bituminous or synthetic membranes, but the thermal insulation is always laid under the membrane.
The advantage of this solution lies in the fact that is well known and has been widely used for a long time thus reducing any possible errors. The insulation is always protected by the waterproofing and its characteristics and performance are preserved at length without any washout effect.
The type of insulation required in this type of application must have the following characteristics:
- excellent insulation properties
- good compressive strength
- resistance to heat
- resistance to solvents contained in bitumen
The most suitable product for this type of application is undoubtedly rigid expanded polyurethane. Please bear in mind that extruded polystyrene and expanded Styrofoam CANNOT RESIST to temperatures over 80°C that can be reached not only during laying, but also in operating conditions. Special attention is to be paid when laying these products in contact with artificial and bituminous membranes with a high content of plasticizers and solvents.
Fiber products DO NOT HAVE adequate resistance to humidity to ensure constant performance over time. Fiber products DO NOT HAVE adequate compressive strength resistance to humidity to ensure constant thickness and resistance to treading over time. Expended polyurethane panels are the optimal solution for this type of application. Synthetic coatings are blends of resins mixed with plasticizers, stabilizers and pigments produced by extrusion, calendering and spreading.
The structure can either be homogeneous, stabilized and reinforced or even fiber-reinforced. The use of a synthetic membrane at sight requires the use of anti-UVA additives. The polyurethane panels can be laid dry or with compatible additives; the synthetic membrane must always be left free from the insulation. The joints between the coating’s components are achieved by hot welding or with solvents.
The various layers can be laid dry in case of ballasted coatings.When dry laying is not recommended, the coating can be fastened mechanically or glued with adhesives. Hot bitumen is one of the most widely used. A quantity of about 1.5-2 kg/m2 is spread evenly on the surface to be bonded.
The separation layers (non-woven fabric of about 500g/m2) inside the package protect the vapor barrier, normally composed of a polyethylene sheet and synthetic coating, against the roughness of the laying surface and abrasions caused by the ballast layer. POLIISO® VV expanded polyurethane panels with glass fiber supports are the recommended type of insulation for this type of application, because they ensure good compressive strength values, excellent thermal insulation values and resistance to the high temperatures that develop under the membrane both during laying and service life.
PORTICO FLOORING
PORTICO FLOORING (PILOTY FLOORS)
Floor / floors
This building system has become quite frequent in recent years.
This flooring is laid on open porticos, namely floors built on a building's load-bearing pillars. Despite the fact that this building system is widely used, it gives rise to several problems, among which the major thermal dissipation and low temperatures that this type of floor is exposed to. Great attention is hence needed when building a structure like this and, in particular, excellent thermal insulation needs to be applied on the outer part of the building.
Said insulation must also be highly resistant to compression, as it must bear a part of the structure's weight. Extruded polystyrene is the thermal insulation that ensures both characteristics and is appropriate for this type of application.
Laying: once the building's structure is erected on the portico, the X-FOAM® WAFER insulation panels are applied directly on the portico after leveling the surface.
The panels are glued on the support using cement-based adhesives. Therefore, the panels must have a rough or embossed surface: it is necessary to ensure the best possible gripping with the adhesive. It is also recommended to fasten the panels mechanically to the support. Once the insulating layer is fastened, it is coated with a layer of plaster reinforced with synthetic fiber or with a composite layer of smooth plaster reinforced with a fiberglass net and a plastic finish.
EXTERNAL INSULATION
WALL / EXTERNAL INSULATION
The thermal insulation system of a building from the outside, commonly known as "external insulation", has been considerably diffused in the last 30 years and is the most suitable solution for the renovation of vertical facades. This system consists of applying slabs or insulating panels to the entire external surface of the building.
Extruded polystyrene and polyurethane foam are particularly suitable for this application as they are light weight, have excellent insulation, they don't absorb water and cling easily to mortars and plasters commonly used.
For this specific application are indicated X-FOAM® WAFER and POLIISO® ED: the first product has a wafer surface and is available in thicknesses from 20 to 300 mm, POLIISO® ED, instead, is a PIR foam panel available in thicknesses from 30 to 160 mm.
The use of X-FOAM® and POLIISO® panels, compared to solutions using alternative insulating materials, makes it possible to considerably improve the performance and the cost-effectiveness of the entire system thanks to a reduction of the thicknesses necessary to obtain the Prefixed thermal transmittance, to a limitation of the weight of the insulating layer, to a lower incidence of the accessories for the fastening and finishing of the system (shorter plugs, less thick profiles, reduced thresholds and sills), to a greater stability in time of insulating performance, mechanical resistance and dimensional stability and end to a lower use of resources and limited environmental impact.
Laying: the wall must be flat, without any dislevels above the centimeter, clean from residues and dry. The X-FOAM® and POLIISO® panels must be fixed to the structure with a normal adhesive mortar with continuous curb on the perimeter of the slab and center point. Moreover, they must be fixed mechanically to the masonry by means of coat plugs, at least four points, near the edges of the slab. The first layer of shaving is then stretched in which a glass fibre network is drowned, with a reinforcement function. After eliminating any imperfections from the net, the following protective layers are drawn up to the external finish, which is generally made up of mineral-based paints.
