A recent research has revealed that foam insulation observed in a number of homes over the last 25 years has been showing a poor effect now.

The research has been compiled by Branz, highlighting severe problems associated with the infusion of retrofitted urea formaldehyde foam insulation (UFFI).

Airfoam General Manager Tony Casey said that the Company has been looking at numerous defects in the methodology of UFFI. It has been working in collaboration with Branz and EECA.

The insulation is essentially done in the walls and rendered dry. Now, the effectiveness is fading away, with cracks being developed in the walls.

The report said that the effectiveness has reduced by more than 60%. The procedure sees holes being made into the walls, wherein the hoses are injected later.

Now, the drilled holes are developing empty spaces. This is result of the negligence of the workers who would have missed to fill in the spare holes, said the report.

"Laboratory tests ... have also indicated that the installed product does not meet the claimed performance specifications", the research report said.

The issue first came to the forefront after EECA discovered that the warmth yielded at the homes after the insulation was not up to the mark.
