Although the facing material may vary (typically OSB or a cementatious product) SIPTEC panels have the common characteristic of a rigid foam core sandwiched and adhesively welded / fixed between two exterior "skins."
The first known SIP panels were created back in 1952 by Alden Dow, son of the owner of the Dow Chemical company. These buildings have been in continuous occupation ever since and are still structurally sound. Historically, the principle of using two cooperating faces was introduced by Delau around 1820. The first extensive use of sandwich panels was during World War ll. In the " Mosquito" aircraft.
Today with the advent of cellular plastics sandwich construction composites can be found in a diverse range of products, Siptec directors have worked on Trains, Ships, Racing Yachts, R.N.LI, Lifeboats, Stealth Aircraft, and Submarines, wherever HIGH STRENGTH and light weight are needed…
Following the energy crisis in the 1970’s SIPs began to emerge as an alternative construction method, but it has been in the last 20 years that SIPs have really taken off in the USA, Canada and Japan where the markets are said to be growing at 50% per annum.
The core foam used in SIPTEC panels is a Modified Poly Foam, designed to display absolutely consistent density properties.
Modified Polyfoam has some unbeatable qualities:
- No CFCs or HCFCs
- Will not absorb water
- No Formaldehyde
- Environmentally safe and inert
- Highest U-value per kilo
- Completely recyclable
- Contains no harmful fibers
MPF represents an efficient use of natural resources, saving energy and conserving resources through its manufacture, use and disposal.
SIPTEC & SIPCRETE panels come in a range of thicknesses. The performance figures are unparalleled, and speak for themselves.
