Premium fiberglass doors using LFI-PUR

Jeld-Wen (Klamath Falls, OR) recently introduced their new Premium Fiberglass doors made with PURfiber technology developed and produced using Krauss-Maffei’s long fiber injection processing technology for polyurethane (LFI-PUR). In the LFI-PUR process, glass fiber from a roving is mixed with a polyurethane reaction system. The mix is placed into an open mold, the mold is closed and the part is formed under pressure, causing the glass filaments and the PU to bond into a high-strength composite.

Currently fiberglass doors account for only 12% of the exterior door market. Jeld-Wen believes that this percentage should be much larger and, as a result, has spearheaded a massive R&D project, using Krauss-Maffei’s LFI-PUR technology, to generate the advancements and improvements required to create this next generation of exterior fiberglass doors.

Jeld-Wen claims that their Premium Fiberglass doors made with PURfiber technology are stronger and more dent-resistant than any other fiberglass door on the market.

“The advantages [of the LFI-PUR Premium Fiberglass doors] for homeowners and builders are huge in that we have developed a product that not only delivers all the benefits offered by fiberglass, but goes well beyond them with regards to strength, reliability and style diversity,” said a spokesperson for Jeld-Wen.
