Energy Saving Insulation in Pittsburgh, PA


  • Insulation works for you year round by reducing both heating and cooling usage therefore saving you money on utility cost while giving you a more comfortable living and working space.
  • Most homes built before the 1960's have little or no insulation, increasing utility costs.
  • Proper insulation can reduce your environmental impact by reducing the amount of chemicals released.
  • New construction: Now is the time to rethink insulation before the walls are up and you come face to face with a drafty house and high energy bills. Insulate right the first time.
  • Prevent the transfer of heat out of the house in winter and into the house in the summer with the proper insulation. The ability to stop the transfer of heat is expressed in R-value, or the resistance to heat flow. The higher the R-value, the more heat the insulation will resist. We provide cellulose and spray-foam insulation services for contractors or homeowners.


Cellulose insulation is a green choice for insulation as it is manufactured from recycled paper reducing the amount of waste put into landfills and the environment.

Cellulose requires much less energy to manufacture than mineral fibers such as rock, wool, or fiberglass reducing the strain on our natural resources. It has the lowest carbon footprint of insulation products made today.

Blown-in cellulose is ideal for retrofit jobs and the new construction market for the following reasons:

Benefits of Cellulose Insulation

  • Flows Around Wiring and Plumbing
  • Gives Blanket Coverage in Attics
  • Non-Toxic: Contains No Asbestos, Formaldehyde or Fiberglass
  • Treated with borates to ensure it is fire-retardant
  • Non-Corrosive
  • UL Labeled & Tested
  • Does not support growth of mold or mildew
  • Fills irregular size openings and gaps


Your attic is your biggest source of heat loss according to the Department of Energy. Adding insulation to your attic is the most cost effective thing you can do in your home. By installing the proper amount of insulation in your attic, consumers can notice an immediate saving by the reduction of energy usage and a much more comfortable living and working environment.

Garage Ceilings

If the rooms above your garage are drafty and are colder than the rest of the house you may need to have cellulose blown into the garage ceiling. As long as the garage ceiling has drywall, plaster board or a sturdy surface we can insulate it. We make access openings in the ceiling and upon completion of work the openings are capped with 2” caps.


Cellulose can be blown into existing walls whether your walls are brick, stone or siding. Blown in cellulose can be installed from the outside or the inside of your home or building. There may be some situation where cellulose cannot be blown such as a home with double brick sidewalls.

In brick or stone structures we drill through the mortar joints and re-mortar the access openings upon completion of work. Vinyl siding can be lifted then access openings are drilled and upon completion of work the openings are capped and the siding set back in place. For aluminum or wood, we need to look at each to job to determine the best way to access the walls for insulation. Some sidings cannot be lifted or taken off safely without damage therefore these walls may be drilled and capped with 1” caps or plugs upon completion of work. Sometimes the siding material can be cut out and reattached upon completion of insulation work.

If there are areas that cannot be done from the outside or you prefer, we can insulate from the inside. Access openings are made through the walls and upon completion of work the openings are plaster patched to match the existing finish as close as possible.

If there are attic and kneewall areas that need insulation and you have no access to these areas we can make the access openings and repair the plaster upon completion of work. We do not paint the repairs however we can refer a well-qualified painter to you should you have that need.



Spray foam insulation is great for all construction types such as wood or steel frame. It can be used on homes, additions, garages, metal buildings and barns. . For walls, attics, vaulted ceilings, band joist and foundation level work both above and below grade. Spray foam is a superior insulation product compared to the traditional fiberglass insulations.

Spray foam may cost more than the other insulations, but it has many benefits that make it appealing to the property owner. Spray foam increases the energy efficiency and comfort level of a structure by controlling air movement through the building. It can even allow for downsizing of the HVAC system. Spray foam does not shrink, sag, settle and is not biodegradable. Customers often realize energy savings as high as 50% when compared with conventionally insulated buildings.

Benefits of Spray Foam

Spray has many benefits that make it appealing. The energy savings alone of having spray foam installed can pay down your investment cost many times over. Customers often realize energy savings as high as 50% when compared with conventionally insulated buildings. Spray foam is also:
  • Environmentally Friendly
  • Formaldehyde-Free
  • Mold & Mildew Resistant
  • Ideal for Noise Reduction
  • Energy-Efficient
  • Resistant to Air Transfer
  • Non-Corrosive
  • Reduces Condensation
  • Great for Residential and Commercial Use/ New and Existing Construction
  • Draft free environment - Seals cracks, joints and irregular voids. Spray foam prevents uncontrolled movement of air through the wall cavities.
  • Improved indoor air quality: Reduces allergens, pollen and external dust from entering through the walls therefor improving the indoor air quality.

Types of Spray Foam

There are 2 type of spray foam we use. Open cell foam sometimes referred to as semi-rigid foam and closed cell foam referred to as rigid foam. Both have specific properties for use in particular insulation projects.

Applying Spray Foam

Spray-foam insulation is applied as a liquid that expands and cures within seconds to create a solid mass of insulation. We spray the liquid from equipment mounted in a trailer through a nozzle into wall cavities, ceilings, knee walls, slopes, and crawlspace areas. It expands to fill the wall cavities and voids that are often missed with traditional fiberglass insulation, leading to air infiltration and condensation problems. Because it expands into tight areas, spray foam is ideal for insulating steel framing and around outlets.


Sealection Agribalance is an open cell spray foam. It is a Green Approved Product with an R-value of R=4.5 per inch. It is a 2 component semi rigid foam applied as a liquid which expands 120 times it liquid volume to insulate and seal all gaps cracks and joints in a single application. It cures within seconds of spraying to a semi-rigid mass of insulation.


Heatlok Soy is a 2 component spray applied closed cell rigid foam. It is a 2 pound foam with an R=value of 7.4 per inch. Heatlok closed cell spray foam has a higher R value per inch than open cell spray foam and also has a higher cost than open cell spray foam. It is great for areas where you need a higher R-value but have a restricted space in which to insulate such as 2x4 wall or vaulted ceilings. Heatlok closed cell spray is perfect for metal buildings, barns, refrigeration units, below grade applications or anywhere where moisture may be an issue.

Heatlok Soy allows you to achieve in 1 application the following 5 benefits:
  • Air barrier
  • Insulation
  • Water resistive barrier
  • Vapor barrier
  • Drain plane
