The compressive Strength of thermal insulation materials is determined by short term standard test methods. The data given in the table refer to a deflection of 10% or yield value within 10% deflation. For the structural applications involving continuous high compressive load, non uniform loads of high temperature, while designing an adequate safety factor in design stress levels should be provided to minimize deformations with time. These values are reduced at higher temperatures but the mechanical properties are not affected adversely at lower temperatures down to 40*C (-40*F).
Resistance to water and vapour penetration
Polyfoam absorbs negligible amounts of water because of its structure which consist of small sized closed cells and outer form skin of denser material on both sides. Therefore polyfoam will remain dry in the high relative humidity and high ambient temperatures of the Middle East.
Polyfoam is stable and has good resistance to acids, basis, cold bitumen, silicon, and oil.
Polyfoam can be easily cut with wood working tools and can also be cut by hot wire and can be bonded with suitable hot bitumen and with special adhesive for polystyrene foams. A wide variety of size and the easy handling makes it possible to fix the boards to almost any shape.
Polyfoam is odorless, and not supporting with the pests friendly environment.
Polyfoam is polystyrene foam insulation and as such it is 100% recyclable. Separate machinery recycles the debris and for the production.
Effective thermal insulation with POLYFOAM products are highly effective by contributing by reducing emissions of carbon dioxide (CO2).
POLYFOAM insulation makes the buildings that are more healthy and comfortable to live in. Even in high and low temperature, POLYFOAM protect the building and subsequently the fabric of the building is protected from the temperature and the moisture as well. This prolongs the life of buildings and enhances their value. POLYFOAM is the environmentally friendly insulating material and it will prolong the life time of the building.
depends upon its correct installation in accordance with good building practice.
