About Polystyrene rendering
Industry of design and construction has passed through the evolution process due to the invention and implementation great deal of new materials. That especially concerned items of the houses appearance finishing and energy efficiency demands and standards.
There plenty of different ways of making the walls of a house to keep warm inside.
One of the newer rendering methods is Polystyrene rendering. Its popularity has been sky rocked over the latest years.
The necessity of better wall insulation as well as pressing requirements for the energy efficiency made polystyrene the most desired rendering.
It is known that the polystyrene is quite good insulating material. Moreover, it was successfully introduced in house and building constructions, mostly for exterior walls. It was used as a formwork for the concrete. In addition, it was used for interior walls, basements or ceilings.
Such a technique is referred to as Insulated Concrete Formwork and needs to be acrylic rendered.
Polystyrene rendering has evolved a lot from cement rendering and so now we have the polystyrene foam render.
It is available in a wide variety of colors and there are various finishes.
If you want more appealing look, well, there comes the texture finishing over the polystyrene.
The pre-blended polystyrene is a flexible thing and eventually render quality turns to be much consistent and superior.
This material possesses ability to be applied for almost all kinds of surfaces including steel frame building, bricks, and polystyrene sheets.
One should distinguish extended polystyrene (EPS) and extruded polystyrene (XPS)
Extended polystyrene is also called Styrofoam. It is rather lightweight and consists of expanded polystyrene beads.
Extruded polystyrene (XPS) is manufactured using a process of extrusion. This continuous process results in a closed cell structure with a smooth skin on the top and bottom of the board. The closed cell structure of extruded polystyrene (XPS) prevents water penetration to the structure of the insulation board and provides long term strength and durability.
Expanded Polystyrene insulation (EPS) is manufactured using beads of foam within a mould, heat or steam is then applied directly to the beads which causes them to expand and fuse together. This process produces a closed cell structure, not a closed cell insulation board, due to voids that can occur between the beads.
In building and construction, there is a measure of how well the building, per unit of its exposed area, resists conductive flaw of heat. This is the R-value indicator. The higher the resistance is, the better the thermal insulation properties of the object.
It is commonly understood that XPS offers more initial R-value per inch than EPS but because of its lower cost, EPS offers more R-value per dollar
XPS is often branded by its manufacturer and frequently comes in a number of different colors, which have nothing to do with performance. . Since XPS is much more expensive than EPS, buyers would better to compare the characteristics of each product in correspondence to the needs of design and application.
