GET INVERTED FLAT ROOF PERFORMANCE RIGHT WITH NEW WHITE PAPER

A new white paper from Polyfoam XPS is helping designers and specifiers of inverted roofs to understand how systems perform and are certified.

“Getting the right thickness of insulation in an inverted roof means taking account of several factors relating to moisture exposure and rainfall,” said Rob Firman, Technical and Specification Manager at Polyfoam XPS.

“We want to give readers of our white paper the confidence to understand how those insulation thicknesses are arrived at, so they know that their designs will perform as intended once installed on site.”

Third-party certification acts as reassurance for construction professionals that manufacturer’s claims are accurate. However, despite clearly defined standards and calculation procedures, an alternative interpretation of how inverted roofs perform is potentially risking specifiers including too little insulation.

“Our aim was not to say that one solution or certification body is right and another wrong,” continues Rob Firman. “What the white paper shows is that there’s actually little difference between the two interpretations.

“Unfortunately, the way in which the different interpretations are being communicated is not as clear as we believe it could or should be. Our aim is to give designers and specifiers the information they need to make sure they are considering comparable solutions and achieving the performance they intend.”
