…and how we do it. It seems when it comes to insulation, installation should be a straight forward. A contractor comes to the house and gives you an estimate, then adds some insulation to the attic, basement, walls and/or crawlspace. Although this was okay twenty or thirty years ago, a lot has changed in housing and the construction industry since then.
Subjin Insulation Services offers a comprehensive approach to any insulation job. We don’t cut corners. We follow state and federal guidelines when it comes to insulating your home. It’s important to know there are some sensitive health and safety issues that can come up if an insulation project isn’t done properly, such as: Lead, Carbon Monoxide, Mold, Moisture, Ventilation, Fire hazards, etc. Subjin Insulation Services’ approach is to test in then test out following BPI procedures; assuring safety and proper ventilation to the home, and fossil fuel heating appliances.
Deploying cost-effective solutions is our area of expertise. We have over a decade in the energy services business; including appliance replacement recommendation, A/C, heating, water heating, etc. We will give you our best analysis of your home.
Subjin Insulation Services has some of the most expertly trained and experienced employees in the field today. We always strive to stay informed, up to date the latest certifications and working with the ARRA project and utility energy services; we have achieved a higher level than any of our competitors.
When we begin talking about attic insulation most customers ask, “How much do I have?” and “How much do I need?” We measure insulation by the R value. The R value is a measure of resistance to heat. The higher the R number the better job that the insulation is doing. For our area in the Lehigh Valley, the minimum is R-38 for the attic. Energy Star recommends R-49, and we agree as it provides energy savings as well. Most attics that I see are under insulated. Insulating your attic has proven to provide the largest and quickest results for energy savings and comfort.
Subjin Insulation installs a variety of insulation types; some are better than others at insulating. We install batt type insulation, blown in fiberglass and cellulose, and 2 part spray foam.
When evaluating your home for insulation, the type and age of insulation is what you look at when determining R value. With age everything wears out, including many types of insulation. The fiberglass insulation installed in the ‘70s will not give you the same R value as it may have when it was installed. Studies show fiberglass loses 40% of the effective R value in about 7 years. In many cases, blown in fiberglass can lose effectiveness sooner.
Why? One reason is because fiberglass gets its R-value from the air space between the glass. When cold winter temperatures come into contact with the insulation, the air space shrinks and it does not expand back. After many winters, the effective R-value decreases considerably. This doesn’t happen with spray foam or cellulose insulation. We’ve removed many R-19 batts that were 6” when installed, now they are 1.5” thick!! Fortunately this doesn’t occur with spray foam or cellulose insulation.
The R values are different for each type of insulation
Cellulose R 3.8 p/in.
Fiberglass batt R-3.0 p/in.
Blown-in fiberglass R-2.6 p/in.
2 part foam R-6 p/in.
Air sealing the attic is the most important measure to perform before the insulation. It’s a way to save energy even if you have R-49 in your attic currently. Before we insulate, it’s important to foam and seal, any electrical or plumbing holes, cracks and openings between the attic floors.
Why is this so important? Heat loss happens in a home in 3 ways: radiation, conduction, and convection. Convection is the air movement portion. Warm air rises through these cracks and openings and there goes the heat you paid for! Foaming, caulking and sealing are great effective ways to prevent this convective heat loss.
Your Home needs proper ventilation to prevent moisture build up and to have proper air exchange in the attic. Even with excellent air sealing techniques, some moisture can get into the attic and this moisture needs a way to escape. Proper ventilation is required. We check and add any ventilation when needed.

Basement / Crawlspace
Subjin Insulation provides the best quality insulation for Basements and Crawlspaces. As with Attics, it is a good idea to air seal before insulation. We can air seal the perimeter cracks plumbing, wires and other openings, giving the basement a warmer environment. We can remove the old hanging insulation too. We can provide a vapor barrier in the crawlspace preventing moisture from entering the home.

Subjin Insulation has many qualified technicians for wall insulation. Wall insulation of existing residences can be a labor intensive job. This is because of the nature of the installation process; many holes need to be drilled and/or siding removed. If your home was built prior to 1978 there are changes regarding the ways we insulate your home. We are an EPA registered firm. All employees are lead certified and comply with all lead regulations providing safety to you and your family. After Attic and basement insulation, wall insulation is the next priority for the home. It is cost effective, just more labor intensive than the attic and basement. We have decades of experience and pride ourselves on quality
