Between 1,500 and 1,800 square feet of Kingspan’s Optim-R vacuum insulation panels were used in the retrofit project for the student housing building. Kingspan’s Optim-R is a next-generation insultation comprising rigid vacuum insulation panels (VIP) with a microporous core, which is evacuated, encased and sealed in a thin, gas-tight envelope to give outstanding R-values and an ultra-thin insulation solution.
“The existing roofing system’s insulation thickness was minimal and the doors and through-wall air conditioning units were very low,” said Michael Stripunsky, Senior Associate, Superstructures Engineers + Architects. “The distance from the top of the existing concrete deck to the bottom of the air conditioning unit wall penetration was less than eight inches. If traditional insulation had been used, the top of the new roofing system would have been just at the level of the wall opening.”
Optim-R's high level of thermal efficiency - up to R-28 on 1 inch and R-57 on 2 inch using calculated edge thermal resistance properties—combined with minimal thickness, provides an ideal solution for applications like that of the student housing building, where a lack of construction space or depth was an issue. Optim-R made installation fast and easy because of its ultra-thin nature and its effectiveness for when space is tight.
“In a case like this, using Optim-R was a cost effective and efficient solution. We saved the client money and time, and allowed for normal building operation,” remarked Stripunsky. “Using Optim-R also allowed us to avoid costly modifications to the existing perimeter conditions.”
