Advantages of building with SIPs

There are many advantages of building with Duratherm SIP products!

If your goal is to build a stronger, safer, more energy efficient home or building, which is also environmentally friendly and financially practical, in much less time than typical building systems, than building with Duratherm SIPs is the solution.

The Duratherm Mexico SIP panels are unique when compared to normal SIP systems.

In an effort to target safety, our Duratherm structural insulated panels recipe begins with a polystyrene core, of the highest density used in the industry. Furthermore, instead of using OSB (oriented strand board) for the outer sheeting, we have chosen the stronger cement sheeting, which offers several advantages to the customer. To begin with, the panels arrive from the factory ready for painting or tiling, eliminating the cost and time associated with waterproofing and preparing sheet rock. In the long term, this product will lower your cost of maintenance and will provide a mold- free environment with far greater ease than its wooden (OSB) cousin.


What are SIPs?

SIPs definition: structural insulated panels with a polystyrene core used for modern roofs and walls to build an earthquake- proof house and efficient green thermal home designs for hot and cool climates. Structural insulated panels (SIPs) are high performance building panels used in the construction of floors, walls, and roofs in residential and light commercial buildings.


 “SIPs share the same structural properties as an I-beam or I-column. SIPs replace several components of conventional building such as studs and joists, insulation, vapor barrier and air barrier. As such they can be used for many different applications such as exterior wall, roof, floor and foundation systems.”  - wikipedia

Structural Insulated Panels

SIPs are fire resistant, self-extinguishing and non-toxic. Their thermal insulation properties are superior to those of other products:


  • The 4 inch wall panels have R-26 value.

  • The 5 1/2 in. floor or roof panels have R-39 value.

  • Vacuum insulated panels have the highest R-value polystyrene insulation at roughly R–6 and R–5 per inch.

Strength of the panels far exceeds normal specifications, resisting a flex load of 5000 pounds per square foot.

No other building material on the market can effectively compete with these Duratherm panels for the extreme safety and comfort that is also affordable.

SIP Panel Sizes

Floor and roof panels are 6” thick. Wall panels are 4” thick. All panels have both facings of 3/8 in. thick hardboard fiber cement sheet panel. Panels come in lengths of 8’ or 10’ or 12’ providing builders with maximum buuilding flexibility.

SIPs are easy to cut with standard hand tools, which eliminate complications on the job site. We can also cut the panels for you at our factory if preferred. We prepare the panels for easy assembly by placing identifying marks before shipping them to you for assembly.


Eco Friendly

Our panels are made of renewable materials that are 100% recyclable. The UN has approved this material for green building projects. The added insulation of the polystyrene creates a far more efficient home than conventional timber or concrete building methods. The polystyrene insulation of the panels provides great soundproofing and thermal resistance qualities.



Our 5 star polystyrene installation reduces your utility costs by 50% to 70% while lowering your carbon footprint and promoting a cleaner world.

Duratherm SIPs are a clean product that produces no greenhouse gases.

The insurance companies agree with our assessment offering lower rates. SIPs qualify under the new cap and trade bill as an approved energy efficient product.

SIPs – an approved building material for earthquake zones.


In 2004, the International Code Council’s Evaluation Service (ICC-ES) approved the use of structural insulated panels (SIPs) on the West Coast of the USA where high-risk seismic zones exist (Seismic Categories D1, D2, and E.)

This is good news for all building professionals and home buyers who want a stronger, safer home with the energy savings and comfort that SIP built homes provide.

Less Waste

We have simplified our system and increased our production time by using cutting edge adhesives and refined assembly methods.

The panel factory in Mexico makes each structural insulated panel as a sandwich. The outside surfaces are fiber cement sheet and the core is EPS (expanded polystyrene) used for insulation. This simple sandwich panel forms an amazingly strong insulated panel for building. You can then use any kind of finishing, stucco, tile or rock.



SIPs have been found to be the safest building system for earthquake zones. Our product can also withstand 200 mile per hour winds for hurricane prone areas.

Because this modern building product is fire resistant, it can be used to make a fire break between rooms. Your children will be sleeping in the safest building system money can buy when you build a SIP home.
