Unlike traditional fiberglass, polyesters, Jet Stream Insulation Rotorua can conform to uneven surfaces — filling the smallest cracks and the low access areas traditional insulations usually miss. That tight fit will seal air leaks, keeping the cold out in the winter and the heat out in the summer. It also helps to seal out moisture, and that can eliminate health problems from mold and mildew in the years to come. The ability of blown-in insulation to flow into tight spots makes it the most energy efficient insulation, and it will also deaden sound between rooms – a real plus if you don’t like your kids’ music collection. One of the most increasingly popular forms of insulation is the blown-in type — a substance made of the likes of cellulose, fiberglass, mineral wool or sheep’s wool. If you aren’t familiar with the blown-in option, we at Insultech Insulation want to introduce you to this form of insulation, and the ways it is beneficial over the more traditional insulation.
