INSULATION

INTERIOR INSULATION

Wall / Interior

Insulating perimeter walls from the interior, namely dry lining, consists in thermally insulating walls from the inside of a building, that is to say, the part facing the heated room, without resorting to expensive works on the structure or facade. It is a widely used system during building renovations or to increase comfort and energy conservation in a condominium's housing unit.

This system is preferred in all those cases in which thermal insulation is poor, in rooms that are used occasionally as is the case of second homes, if you prefer a system with lower thermal inertia, namely with a faster response to heating, or if you wish to avoid bothering those living in the housing unit with long masonry works.

Another type of application is thermal insulation of rooms below ground from the inside. Besides saving energy, good wall insulation greatly improves living comfort; even a difference of 2 °C between the walls of a room can create convective air currents that make a room less comfortable.

ADVANTAGES

-Fast heating -Low cost -Clean working -Laying not affected by weather conditions -Higher surface temperatures and hence greater comfort -No architectural modification needed

PREFABRICATED PANEL

The GIBITEC® ES prefabricated panel has been designed for this type of application. It has a layer of plasterboard coupled with a layer of X-FOAM® extruded polystyrene without extrusion skin to ensure top thermal insulation, very low water absorption, high compressive strength and constant performance over time. The product is ready to be laid and it can be directly glued and mechanically fastened to the perimeter wall. During laying, the joints are to be sealed with reinforced filament tape and special mortars.

When laying the panels, it is good practice to pay attention to their alignment and avoid that any adhesive or stucco seeps through the joints. The surface is ready for a final hand of paint. If the walls are not perfectly perpendicular or have rough surfaces, we recommend the GIBITEC® ES panels on a frame of strips previously built to create a cavity useful for scattering vapor or installing systems. Use X-FOAM® shims to lift the GIBITEC® ES panel off the ground to avoid that the plasterboard layer is affected by the hygrometric conditions in the joint between the floor and wall.

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.

APPLICATIONS

CAVITY WALLS INSULATION - POLISTYRENE

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 insideaccumulates 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.

In this type of application, we recommend using a product that can guarantee constant and durable performance over a long period of time, since the insulation layer cannot be accessed during a building's entire life cycle, and that affords a high resistance to water absorption. Extruded polystyrene has all these properties and, since it is also breathable, there is no need for laying a vapor barrier or air barrier; X-FOAM^® LMF is especially easy-to-use and it makes laying fast thanks to the length of the boards (2800 mm) because they cover the entire wall from top to bottom. 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.

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.

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.

VENTILATED WALL

The ventilated facade is marked by an uninterrupted ventilated air chamber between the outer face, which can be made of the most diverse materials and the inner face on which the insulating layer is normally applied. The air chamber provides for the dispersion of water vapor and avoids that it condensate thus preventing moisture; the outer face protects the insulation panels from UV rays and bad weather.

The polyurethane foam is particularly suitable for this type of application for the very low water absorption values and for the vapour permeability, besides of course the good values of thermal conductivity (λ) and of dimensional stability. POLIISO®FB thanks to its excellent reaction to fire (Euroclass B s1 d0) is particularly suitable for the thermal insulation of ventilated facades and buildings subjected to fire prevention.

Laying : Anchoring plates to hold the facade's finishing or outer covering are amounted on the inner wall or on the support wall usually made of bricks or cement blocks. The anchoring system consists of a frame made of vertical and/or horizontal bars. Once the bars forming the anchoring system are mounted, the POLIISO®FB insulation panels are laid by fastening them mechanically to the support wall. This creates a ventilated air chamber with a thickness of about 3 cm between the insulating layer and the outer face. The facade's finish, usually made of thin ceramic, stone or metal plates or tiles, is then mounted on the frame to finish the whole.

WALLS BELOW GROUND OR WALLS RETAINING GROUND

In most buildings with a cellar, garage or rooms below ground, earth-retaining walls are those that dissipate most heat due to the low temperatures of the ground that comes into contact with the wall. Moreover, below-ground rooms are being used increasingly to make them more livable.

Thermal insulation is extremely important and extruded polystyrene is especially recommended for this type of application not only because of the excellent thermal insulation values, but also because of the great compressive strength. In this application, the pressure exerted by the ground on the thermal insulation requires the use of insulation with high compressive strength.

Laying : Walls need to be duly protected and waterproofed. The X-FOAM® HBT 500 insulation layer can then be laid making sure to fit them together closely. The panels are applied dry and by points starting from the bottom. The insulating layer is to be protected by a waterproof sheath. The last step is to fill the wall's extrados making sure to apply a filtering fabric on the insulating layer and a layer of gravel between the fabric and the ground to allow filtering so that the ground does not ruin the insulation panels.
