"

Insulating the exterior walls of our two story, 1700 sq ft house, involved drilling holes between each stud, blowing in insulating material, plugging the holes, spackling over the holes, priming and finally painting the holes.  Two man crew was very efficient in setting up scaffolding and then doing the work described.  We got a chance to see what the insulation looks like inside the wall when the force of the insulation popped out a built-in bookcase that was not secured.  Its a solid blanket of insulation, filling in the entire space.   Very impressive.  The results have been very noticeable.  The house feels more comfortable, and the heater turns on less frequently.  We should have done this years ago. 

Last part of the project was to blow additional insulation into the attic, which went very quickly.  Overall, the project took 2 very long afternoons/evenings to complete.  It makes a mess around the outside of the house, but they did a good job of cleaning up each day.

Insulation questions, answered by experts

You won’t find anything inside a cupola on a house because it’s hollow (think of an upside-down cup), allowing air to ventilate out of a roof via vents and light to come in via windows. They also usually have a base, vents around the middle (usually louvers), and a pointed cap at the top.

Yes, PEX pipes should be insulated in certain situations. While insulation is not always necessary for pipes running through insulated interior or external walls, it is recommended for any pipes located in uninsulated rooms, unheated areas, or outside, especially in regions with cold winters. The primary reason is to prevent freezing. Although PEX is more resistant to cracking from freezing than other materials, repeated freezing and thawing can weaken the pipes over time, increasing the risk of a burst.

Although the cost might seem high, winterizing your home is important for your health and the structural integrity of your home. Winterizing will keep your home warm and toasty during the cold months and prolong the life of your appliances, windows, pipes, sprinkler system, pool, and more. 

Insulating ductwork improves your HVAC system's energy efficiency by protecting the air from external conditions and preventing energy loss as it travels through the ducts. This means your system doesn't have to work as hard to heat or cool your home, leading to lower energy bills and a reduced carbon footprint. Additionally, insulated ducts help maintain a more consistent and stable indoor temperature, enhancing comfort. Proper insulation also improves indoor air quality by reducing the entry of allergens and pollutants and helps prevent problems like condensation and mold formation within the ductwork.

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.
