Listed as 1 of 10 top Technologies in 2020

• Duratherm building systems™ is recognized as 1 of 10 Best Green building manufacturer of 2020

• Duratherm building materials have been tested and designed to meet local building code standards 

   in Costa Rica and beyond.

• The UN has approved this material for green building projects. The added insulation of the                             polystyrene creates a far more efficient house than conventional timber or concrete

   building methods.

• Projects built with this product have endured 8.4 earthquakes and category 5 hurricanes.

• The polystyrene insulation of the panels provides great sound proofing & thermal resistance                   qualities. Duratherm SIPs are a clean product and do not produce greenhouse gases.

• SIPs qualify under the new cap & trade bill as an approvedenergy efficient product.

Description of the technical characteristics and performance of "Durathermsips", their structural
use and their insulating characteristics are defined here.

"SIPs" is an acronym for "Structural Insulated Panels". They are used for walls, ceilings, floors
and mezzanines Panels: 

This product is manufactured for applications as eco-friendly walls, ceilings, roofs and floors, and form the backbone of high-performance low energy building systems, in commercial, residential or multi-family projects.


Each piece for wall, ceiling and floor structures are manufactured as a sandwich of two flat fiber
cement boards laminated to a high density expanded polystyrene core "EPS" may be 19 kg/m3
or 26 kg/m3 panels. SIPs are manufactured under controlled conditions and can be adjusted to
almost any building design such as;

∙ Single Family or multi-family residential buildings
∙ Building public areas and private offices
∙ Industrial buildings
∙ Hotels, Assisted living, Hospitals.
∙ Schools, Shops, etc…


The nominal dimensions for the panels "Durathermsips" for structural walls, ceilings and floors

"Durathermsips" for walls, ceilings and roof panels offer R-values starting at 22, providing
insulation, from heat and cold and also acoustic qualities for soundproofing your walls and
ceilings. Achieving unsurpassed energy efficiency ((up to 10 degrees centigrade cooler than the
outside temperatures in hot climates, and reducing your heating costs up to 70% for colder
climates) all the time protecting the environment.
NMX-C-460-ONNCCE-2009 See heat resistant panel for walls and slabs.


Durathermsips are used as walls, ceilings and roofs, for better interpretation define as the Type I
for wall and Type II for roof & ceiling. The fiber cement panels of 5/16inch thickness or greater,
attached to both sides of a core of expanded polystyrene (EPS) of specific density working
together as an element that creates a monolithic piece of certain features, its design specific
characteristics they are suitable building "Durathermsips" durable material with the following
See charts of values for panels type I for walls and II for roof and ceilings, interpretation of the results taken
by the certification. Reference NMX-C-405-1997-ONNCCE

The modulation of the project for "Durathermsips" is very important because this allows the construction system to be more efficient in the amount of required materials, construction time, labor, and ultimately generates less waste while lowering costs.
It is up to the construction project and it is from this as the dimensions of the building are defined, and
give us the result of the number of panels for the wall and roof. The method takes into consideration the modulation, the standard measurements already described for panels modulating from multiples of 1.22cm long. The goal is to reduce labor and material costs by choosing sizes of doors, windows and walls that offer economy of cost while maintaining the architectural integrity of design desired by the client. Compliance with local building regulations, and safety is generally surpassed.

G. Foundation

We recommend a foundation slab designed in accordance with the structural calculations
determined by referencing local soil tests, building weight, and geometry of uses. Respecting
the characteristics of resistance Fc 'and position of steel or glulams specified in the project.
