Wall insulation polystyrene can help your home remain at an even temperature and lower external noise and moisture. Plus, it helps protect it against external noise that might affect its insulation capabilities.
EPS and XPS insulation boards are popular wall insulation materials, made up of millions of microscopic air bubbles that block heat transference.
Thermal Conductivity
Polystyrene wall insulation is an effective choice to help maintain an even temperature inside of your home, as it reduces external noise while being fire resistant and moisture proof – as well as stopping mould from growing within wall cavities. It offers comparable insulating power as mineral wool but is much easier and cheaper to install.
Insulation material can be easily installed into wall cavities using an injection gun, starting off as liquid before quickly changing to foam form within minutes. Once in place, this insulating material fills any air gaps it encounters before hardening into an impenetrable structure that doesn’t leak air. For optimal performance and effectiveness, drill machines or dowels should be used to secure this type of insulation so it doesn’t shrink away and leave gaps that reduce its effectiveness.
EPS wall insulation is composed of plastic and can either come in rigid slabs or as loose, blown-in material that can be installed by drilling holes into inner and outer walls using a special injection gun. In this study, thermal conductivity of different locations within an assembly is evaluated.
Moisture Resistance
Insulation can help your home remain comfortable for living, saving on energy bills and keeping the heat inside for longer. However, excessive insulation levels may create moisture problems which negatively impact health and durability issues in your home.
Expanded polystyrene foam (EPS) or extruded polystyrene foam (XPS) is one of the best wall insulation materials, due to its millions of tiny air pockets which help resist heat flow.
Molded EPS and XPS insulation materials are highly water resistant. Testing conducted by ACH Foam Technologies’ laboratory demonstrates this point; in fact, mold EPS exhibits very low moisture absorption, meaning it dries after wetting conditions quickly while maintaining its R-value. Cellulose insulation on the other hand has higher moisture absorption that could lead to condensation within wall cavities.
Noise Reduction
Insulating walls is a complex task with multiple methods available to you; each approach will vary in its performance. One key consideration when selecting an insulation material for walls should be its ability to reduce external noise such as construction noises, trucks, trains or airplanes – noise from these sources can disrupt your comfort at home or office; insulation materials can help minimize such disturbances.
Polystyrene foam boards are widely utilized as wall insulation due to their ability to dampen sound waves, so those considering using this form of insulation in their home should look for products with an STC rating of at least 30.
Mineral wool and cellulose insulation materials are effective at dampening external noise, and can be installed during new construction or remodeling projects to decrease external noise levels. Both forms of insulation come in batt and blown-in formats for installation into walls during these projects; both options offer fireproof protection as well as moisture-resistance to avoid mold growth in wall cavities.
Durability
In addition to being odourless (unlike traditional glasswool insulation with its thousands of loose fibres that may irritate exposed skin), XPS insulation is extremely durable; lasting years without needing replacement – making it a cost-effective solution.
Polystyrene wall insulation is made from recycled plastic, helping reduce waste. Additionally, its lightweight construction means less carbon emissions from transportation. And thanks to its long-term durability properties, its insulation properties should last many years while helping prevent heat transfer between inner and outer walls.
This type of cavity wall insulation is also extremely straightforward to install. Consisting of expanded polystyrene beads that can be blown into wall cavities with an injection gun, they feature an adhesive coating to stop them blown around should the cavity wall ever become exposed or accessible later; and there’s even a graphite layer which reflects radiant energy back into its source for extra insulating capability.
