Before installing Icynene in our attic, the second floor of our house was unlivable on hot days. We couldnʼt get the temperature below 81 and that was with the AC running constantly. The kids didnʼt even want to play in their rooms! With Icynene, the difference is incredible. We love the energy savings, but the best part is how comfortable it is now. We're no longer stuck living downstairs all summer!
