Tripolymer Foam Insulation Performs Better Than Urea Formaldehyde Products

By Amelia Buckner


Tripolymer was developed as a material for both thermal and acoustic insulation, but is now suitable for use in all residential and commercial structures in White Plains, NY, thanks to its superior fire resistance. A kind of thermosetting plastic, Tripolymer Foam Insulation is a synthetically produced plastic of the phenolics group. This kind of plastic was first used at the beginning of the last century as Bakelite, but today it has many other uses thanks to its excellent fire resistance, durability, and structural integrity.

Many products contain phenolic plastics, from parts found in computer electronics, machinery and automobiles, to various fireproofing materials, tools and waterproof glues; there are virtually thousands of items that contain this kind of plastic which are found not only in the home, but also in the commercial sector. These cellular plastics, when used as wall insulation, have been found to be the safest and most durable type of material for this purpose.

Urea formaldehyde, which was used in adhesives that needed to be water soluble, is a kind of amino plast. As an insulating product, however, it is of inferior structural strength and has a density that is too light. Its simple molecular composition, along with weak chemical bonds, causes this material to be affected by moisture and bacterial attack, so is prone to decomposition in the long term. Tripolymer does not show the same properties as plast foams, therefore will neither decompose nor break down into powder.

Polyurethane and urea formaldehyde foams can be highly flammable and when burned emit toxic gases in large quantities. In comparison, this unique foam does not drip and won't readily combust if exposed to fire. When tested in the laboratory, the by-products created when it is burned are not as toxic as those released from white pine, which is a common timber used in building many homes.

This complex phenolic plastic material is an extremely stable polymer. Samples that were laid under cement slabs showed no deterioration even after more than 25 years from bacteria, water, or physical stresses. Products made of urea formaldehyde have a simpler chemical structure that decomposes after a period of time being in contact with humidity and continual temperature changes.

It is the highly efficient acoustical and thermal insulating properties of Tripolymer that makes it ideal for use in many different buildings, whether existing, new, commercial or residential. It is particularly useful in schools and hospitals as foam for insulation as well as sound proofing, because of its low flammability. Where wall structures are not fire resistant, such as in separation and interior walls, it is able to increase their fire rating.

The superior molecular structure of this insulation foam makes it unlike any other insulating material, including urea formaldehyde, polyurethane or cement. When installed in drywall systems, the drywall is resistant to distortion and deterioration from moisture; this is not the case with products made of urea formaldehyde. In fact, it is most suitable for use in both exterior and interior steel frame or wood stud walls.

Tested extensively in the laboratory, independent results show that Tripolymer installed in walls actually increases the fire ratings two-fold, sometimes more. Other urea formaldehyde products perform poorly when compared against Tripolymer foam, making it the ideal choice for any commercial or residential building in the city of White Plains, NY.
