Although the Bay Area broadly falls under zone 10a and 10b of the USDA Plant Hardiness Zone Map, the localized weather pattern and microclimates differ widely across this region Based on your location, you will know whether you fall under 'foggy' or 'sunny' conditions

It is considered the best product for exterior insulation because of its high durability. The different thermal insulators that could be used in this type of application have lower mechanical resistance. On the one hand, this characteristic translates into a long useful life for the product and, on the other hand, it means that the façade, roof or floor have superior mechanical resistance, a characteristic that is considered extremely important in order to protect the façade from possible blows in its lower part and to support the loads of use on the roof and ground.

Extruded polystyrene is a foam with a closed cell structure.

It contributes benefits to the construction elements where it is incorporated due to its nature and technical characteristics.

The closed cellular structure of extruded polystyrene gives it excellent performance against water and thermal insulation.

The high rigidity of the cell structure gives it a very high mechanical resistance capacity.

The three characteristics that make extruded polystyrene ideal are thermal insulation, low water absorption, and high mechanical resistance.

The thermal conductivity of the products depends on the gas used.

The conductivity can be found between 0.029 and 0.036 W/mK.

The thickness of the product is more important than the thermal resistance.

m2 K/W is the ratio of d to m2

Where?

The thickness of XPS is related to the thermal conductivity.

The closed cell structure of the product allows it to absorb less water than the total long-term immersion.

In an inverted roof, the effect of water diffusion is less than 3%.

This characteristic is used to determine the degree of aptitude of a product.

It is a question of applying a force that causes a small amount of the product to be tested. Products with resistances of 500 and 700 K pa can be obtained, although the standard compression resistance of 300 K pa is the norm.

This characteristic is used to determine the suitability of a product for long periods of time. The values of 125 kpa for loads of 50 years of duration with less than 2% are reached for XPS products of 300 Kpa of compression resistance.

The reaction to fire indicates the contribution of the product in case of fire.

The Euroclass E product is self- extinguishing without the presence of burning drops and is resistant to fire.

The relative changes in length, width and thickness should not be greater than 5%.

It shows the ability of the XPS to support both loads and temperatures.

After 168 h. at 70oC and 40 Kpa, the deformation must be less than 5%.

It is an indicator of the longevity of the XPS.

It is expressed by level 2, which means a loss of strength and an increase in water absorption after 300 freeze-thaw cycles.

The resistance of the material is greater than 200 K pa.

The water vapor diffusion resistance factor shows the magnitude of the product's resistance to water vapor in relation to a stationary air layer of the same thickness at the same temperature.

The manufacturing process of the XPS is comprised of phases.

The panels are made from polystyrene in pellet form. The pellets are introduced into the extruder along with other ingredients to form a fluid.

Under very controlled conditions of pressure and temperature, a foamable mixture is injected into the head and expanded.

The mass coming from the head is shaped to allow a smooth and flat finish on the surface of the panels and homogeneity throughout the perimeter.

The panels are cut to the desired dimensions, the panels are allowed to rest, the grooves and edges are made, and finally the panels are palletized.
