Air sealing spray foam insulation

Spray foam is a comprehensive, tightly packed home insulation that expands to effectively fill gaps and cracks. This air sealing home insulation installs quickly and doesn't have to be cut, fitted, and set like the rigid board. Spray foam also cures to stay perfectly in place, meaning no shifting, settling, or sagging.

Do you have a poor insulation barrier in your attic, crawl space, basement, garage, or in other areas of your Nassau County, NY home? Let the experts at Triple H Insulation help you. With spray foam insulation, we can effectively boost home comfort, reduce HVAC usage, and lower energy bills!

Job Stories From Nassau County, NY
Importance in Baffles in your Attic- Massapequa Park, NY

Baffles are chutes that can provide a channel for air to flow from your exterior soffit vents into your attic space. That airflow is intended to churn the stale air in your attic which helps remove moisture and control the temperature of your attic. They also prevent vents from getting clogged by insulation and ensure a clear channel. Some benefits to having baffles is less mold and mildew, fewer ice dams, and a more comfortable home.

Energy Loss Concerns- Old Bethpage, NY

Jason from Old Bethpage, NY contacted us at Triple H with concerns that energy loss in his home and that his bills have been extremely high for a few months, and he was unsure why. We recommended sending one of our specialists at to perform a Home Energy Assessment to see what was going on in his home. Triple H Specialist Brian went out and preformed the assessment on Jason’s home and discussed his concerns. Brian recommended to seal and insulated Jason’s attic space as well as seal and insulated the garage sealing because that was where most of the air in his home was leaking out. With both these recommendations, Jason’s home should be noticeably more comfortable, more energy efficient with lower fuel and electric bills.

Better Insulated Attic Space- East Meadow, NY

Triple H customer Debra from East Meadow, NY contacted Triple H wanting to get an estimate for better insulation in her attic. Triple h technician Brian went out to her home to take a look at Debra’s attic space and give a recommendation. Brian recommended taking out the old insulation, air sealing the attic space from leaks, and blowing gin 10” of TruSoft Cellulose Insulation to reach optimum R-value. He also recommended sealing her ducts to reduce air exfiltration.  Debra should experience now a more energy efficient home with lower bills, as well as be more comfortable through all seasons.

Benefits of Dense-Packed Cellulose- East Norwich, NY

Dense packing is a technique that packs the insulation in very tightly - so tightly that all irregular shaped cavities and crevices in the wall cavities are filled, and air will not penetrate the dense packed cellulose. It’s remarkable, and something that can’t be achieved with fiberglass - not even close! Dense packed cellulose stops air flow through the wall and insulates. Siding is removed temporarily as necessary and 29/16” holes are drilled through the wall sheathing. A fill tube is inserted up (and down) into wall cavities to not only fill, but dense pack the wall cavities. Holes are plugged and siding is put back. When done right, dense-packed cellulose is a highly efficient option for insulating exterior walls. Also resulting in a quieter, warmer, less drafty home with lower fuel/electric bills, and the heating system runs less which is also less maintenance.

Leaking Can Lights- Albertson, NY

When it comes to making homes more comfortable, stopping air leakage at the top of the house is the #1 priority. Can lights are holes in the ceiling. Air leaks between the fixture and the drywall, and through the fixture itself because of the many holes and seams in it. Resulting in more drafts and colder rooms downstairs.

Triple H went to a home in Albertson, NY and part of the job was installing TiteShell airtight can light covers over all the can lights in the attic space. TiteShell can light covers are installed over all can lights, fitted around wires and fixture struts, and sealed air tight with expanding foam. TiteShell covers are safe from the fire hazards of hot bulbs and fixtures. Once all covers are installed, cellulose insulation is blown into the attic against and over them, eliminating costly gaps in insulation. Resulting in less drafts and more comfortable rooms in the whole home.
