Thinking about insulation? Take a whole house approach to insulation. When contacting insulation companies for multiple quotes, homeowners often have done some research. If the research is misleading or not applicable to their structure, they can make the mistake of paying for an insulation treatment which yields little to no benefit. These 10 questions about insulation are in addition to the obvious top 10 you find on google such as:
bestlink supply professional and honest service.
1. How can you help me identify moisture transfer, and is there a moisture issue creating a food source for mold?
2. How can you help me identify air transfer which is making the home drafty and making some rooms colder than others in winter and hotter in summer?
3. What are the existing types of ventilation, and how are they calculated?
4. What gaps in the pressure barrier ( building envelope) exist at present and what action can be taken to seal them?
5. Type of existing insulation, please identify the R-Value and Material?

Make sure to ask for bids to be submitted (in writing) with the following:
Ask the insulation contractors things like:
Tackling Air Leakage : Making your home cooler in summer and warmer in winter while lowering gas and electric bills.
Green Attic Insulation can insulation over the attic floor or between stud cavities of walls, but insulation cannot solve air flow. It can only prevent heat escape. Let that dominate the conversation through the remaining information.
Insulation and Air Leakage – Unintentional or Accidental Air Movement – Ask your insulator about air leakage.
Often referred to as draftiness, unintentional and accidental air movement account for a host of undesirable conditions, which can be treated and resolved. Green Attic Insulation has offered comprehensive whole house approach energy audits for many years now.
In the process our our years of case studies, we have compiled valuable information on the variables of creating a comfortable home. Some simple and affordable fixes, where the treatment plan would be similar for most homes on the block, and complex and seemingly insurmountable problems which took thermal and blower door testing. This being said, we are careful not to place a percentage on energy bill reduction without achieving meaningful improvements to strengthen the air barrier. Air sealing will stop air infiltration.
What do you absolutely need to know by the time you finish reading this? A stable, healthy, consistent, comfortable , and conditioned living space is the goal. Treatment of the air flow, heat flow, and moisture flow through the conditioned space are the clear objectives. Each of these three have a considerably different treatment application; however, some treatments may overlap reducing the movement of one while directly targeting another.
It is essential to break down these three types of movement into their own conversations and separate the diagnosis and treatment of each. This is a separate but equal conversation when discussing insulation.
Starting with Air Flow. Also referred to as the “pressure barrier” of the structure, air flow ( unintentional / unwanted air flow ) through the conditioned living space is the cause of over-running the furnace in the winter and cooling system in the summer.
Air Movement / Air Infiltration Methods Whole house approach identifying methods of Air Exchange ( per hour)
Insulation and Wind Effect – Think the flag in the yard blowing in the wind. Ask your insulator about wind effect.
Wind / Breeze creates a positive pressure on the windward face and negative pressure on the non-windward facing walls, which pulls the air out of the building. Wind causes infiltration on one side of a building and exfiltration on the other. Wind effects can vary by surrounding terrain, shrubs, and trees.
The most effective treatment would be a continuous air barrier around the entire exterior of the home. This is not achieved with more insulation between stud and drywall cavity.
We find the most vulnerable point of the structure is the seam between the foundation and siding. This can be achieved with exterior caulking or one part spray foam ( depending on the size of the gap and the aesthetics of the building material.
The untreated seams at the foundation level will result in cold first floors around the parameter of the home and cause substantially higher heating costs as cold air is being drawn in through breaks in the pressure barrier.
Wind defense is often overlooked due to seasonal restrictions. For example, the caulking around the window, doors, facia, and any other seams of the external structure cannot be done when the temps are below 40 Degrees per manufacturer recommendations for adhesion and proper curing.
So if a contractor meant to schedule the air sealing of the exterior and spring and never got around to returning, the homeowner ( while the home is new and beautiful) has a major air leakage problem, and resulting higher cooling and heating costs for many years to come.
Insulation and Stack Effect -Think Lava Lamp or Coffee Mug – Insulation ,the mug material, the lid is the ceiling.
The “stack effect” is warmer air moving upward in a structure. This happens in summer and winter, but is most pronounced in the winter because indoor-outdoor temperature differences are the greater. Warm air rises because it’s lighter than cold air. The rising warm air creates positive pressure above, neutral pressure between, and negative pressure on the lower levels. Reduction in pressure in the base of the building, forcing cold air to infiltrate through open doors, windows, or other openings. The stack effect basically causes air infiltration on the lower portion of a building and exfiltration on the upper part.
Indoor Combustion and Ventilation – Indoor bath fans, dryers, range hoods, etc.
Mechanical ventilation air movement varies by device, and can cause substantial pressure differences. A common bathroom fan generates between 90-110 CFM ( cubit feet per minute , a cubic foot is about a basketball of air) , while a range hood over the stove can draw as much as CFM. These devices must be balanced with air intake or result in unwanted air flow through the building envelope.

Now having identified three types of air movement / air flow, we can separate treatment of the air leakage by targeting the same corresponding air movement paths. For example, partitions, pathways, and intersections of the exterior to reduce wind movement. In the attic top plates and wall to wall connections are sealed to significantly reduce stack effect. This includes recessed lighting, attic hatch or pulldown stairs. Openings around flues are flashed and fire-caulked to prevent stack effect though flu clearance framing.
Together we can ask better questions, raise energy consumption through heat escape awareness, improve ventilation, create healthier homes and happier families.

Rigid insulation is a type of insulation that is firm and does not bend easily. It is often used in applications where there is a need for structural support, such as in walls and roofs. Examples of rigid insulation include fiberglass batts, cellulose insulation, and spray foam insulation.
Flexible insulation is a type of insulation that is soft and pliable. It is often used in applications where there is a need to conform to irregular shapes, such as in pipes and ducts. Examples of flexible insulation include fiberglass rolls, mineral wool insulation, and rubber insulation.
The R-value of an insulated wall is calculated by dividing the thickness of the insulation (in inches) by the thermal conductivity of the insulation (in BTU/hr-sq ft-°F).
For example, a 4-inch thick wall with a thermal conductivity of 0.25 BTU/hr-sq ft-°F would have an R-value of 16.
Convection is the transfer of heat by the movement of air. It can be prevented by sealing air leaks around windows, doors, and other openings.
Conduction is the transfer of heat through a solid material. It can be prevented by using insulation to reduce the flow of heat.
Radiation is the transfer of heat through electromagnetic waves. It can be prevented by using reflective materials to reflect heat away from the building.
Fire-resistant insulation materials should be used in areas where there is a risk of fire, such as in attics, basements, and garages.
Insulation materials with a low embodied energy, ODP, and GWP should be used to reduce the environmental impact of the building.
These trends are helping to create more energy-efficient and comfortable buildings.
Each type of insulation has its own unique properties and benefits, and the best type of insulation for a particular application will depend on the specific requirements of the project.
Thermal bridging is the transfer of heat through a material that is more conductive than the surrounding materials. This can occur through metal studs, concrete balconies, and other features of the building envelope.
Thermal bridging can be minimized by using continuous insulation, which is a layer of insulation that is installed without any gaps or breaks. This will help to create a more uniform thermal envelope and reduce the amount of heat that is lost through thermal bridging.
The best insulation installation technique for a particular application will depend on the specific requirements of the project.
