10/10

Sales Rep , Angelo Gabriele, recommended increasing from R40 to R60 levels with cellulose blown in loose fill and changing the in roof venting with better quality air vents . Tom and Brian , installers, did an excellent job in putting down cardboard and blankets to contain any dust build up when installing vents and blowing in the insulation. House was vacuumed and tidied up very well. The bedrooms and house in general is much cooler than previously on very hot days. The temperature balance between floors is significantly closer than earlier which means less electrical and gas bills . Win-win for GNI and us.
