There has been a lot of snow around Boston and Worcester. Your home may look beautiful with all the icicles hanging off the roof, but in actuality, looks can be deceiving. Icicles are a sign of a much larger problem, which can become costly: Ice dams.
Ice dams and icicles form when snow melts, runs down your roof and refreezes near the edge. This only occurs when part of your roof warms to above 32 degrees F, warm enough to melt the snow, while the roof edge remains below freezing. This scenario is often the result of a warm attic. In most homes, heat escapes through ceilings into the attic and warms the wood and shingles directly above it. Although the outdoor temperature is below freezing, the snow melts over the warmed section of roof. When the water from melted snow and ice runs down the roof, it hits the cold edge not warmed by the attic. There it freezes, creating a rim of ice. This rim can grow, trap more water behind it, and bingo—you have a full-fledged ice dam.
The key to preventing ice dams is simply to keep your attic and roof cold. After a snowfall, a cold roof will have a thick blanket of snow. A warmer roof, however, will soon have clear spots where the snow has melted off, and may well have icicles hanging from the eaves.
To keep your roof cold, follow these three steps:
1. Close up attic bypasses
In the average home, about one-third of the heat loss is through the ceiling into the attic. And most of that loss comes from air leaks caused by unblocked walls, gaps in drywall, and cracks around light fixtures, plumbing pipes, chimneys, access hatches and other ceiling penetrations. Air leaks can be tough to stop. You have to climb into your attic, pull or rake back insulation, and plug the leaks using foam, caulk and other methods. Low roof angles make some air leaks difficult to reach.
Bonus: By stopping air leakage to mitigate ice dams, you'll save energy and reduce both your heating and your air conditioning bills.
2. Measure your attic insulation level
You should have the depth of your attic insulation checked and measured. Building codes require about 12 to 14 in. of fiberglass or cellulose. Have more insulation added if you have less than 8 inches and if you have had ice dam problems in the past. Blown-in cellulose and fiberglass are usually better than hand-placed batts, because they fill more tightly around rafters, joists and other obstructions, leaving fewer gaps. It's usually worth hiring a professional for this job; you won't save much by doing it yourself.
3. Add roof and soffit vents
Attic ventilation draws in cold outdoor air and flushes out warmer attic air, cooling the attic and the roof in the process.
Insulation, especially blown-in insulation, can block the airflow. Insulation specialists should make sure the spaces between rafters over the exterior walls are open. Baffles usually prevent this problem. If you don't have them, have them added before installing additional insulation. A shot of air from a compressor hose from the outside will open plugged soffit vents.

For energy efficiency in all kinds of weather, your home should be properly insulated. Too often only in the everyday living spaces are insulated, leaving attics, basements and garages chillier.
Rolls and batts of insulation, made of fiberglass or rock wool, are inexpensive and quick to install in open areas such as an attic floor.
Those are the spots where the most energy is lost. This not only can cause the house to be uncomfortable, it can lead to higher energy bills.
The biggest mistake made is "overstuffing the space."
When there's too much insulation, it stops being an insulator and actually becomes a conductor. Expansion rates vary with foam insulation, and too much can actually cause walls and jambs to buckle. That's a case where too much works against you.
Other examples of what not to do:
Failing to fill the smaller spaces, such as around windows and doors. Even tiny spaces can become big energy loss problems.
Not leaving room for air to circulate. Failure to do this can lead to mold and condensation build-up.
Types of Insulation
Insulation is made of a variety of materials, and comes in four types.
Rolls and batt insulation (blankets) - flexible products made from fibers, such as fiberglass or rock wool. These come in different widths to fit the standard spacing of wall studs and attic or floor joists. Fiberglass batts, the insulation found in most homes, are inexpensive and quick to install. Like other batt-type insulation, fiberglass is rolled and secured into place, but may be difficult to fit around obstacles without leaving gaps.
Loose-fill insulation - usually made of fiberglass, rock wool or cellulose in the form of loose fibers or fiber pellets. This should be blown into spaces using special equipment. It conforms to odd-sized openings.
Rigid foam insulation - typically more expensive, but very effective when used in exterior walls and for special applications such as attic hatch doors.
Spray- foam insulation - can be blown into walls, on attic surfaces or under doors to reduce air leakage. There are several types, depending on the space that needs to be filled and how much you'd like the insulation to expand.
Where to Insulate
Insulating the following areas of your home can help keep you comfortable year-round:
Unfinished attic spaces - between and over floor joists; attic access doors.
Finished attic spaces (with or without dormers) - between studs of "knee" walls (vertical walls with attic space directly behind them); between studs and rafters of exterior walls and roof; ceilings with cold spaces above.
All exterior walls - between living spaces and unheated garages, shed roofs and storage areas; foundation walls above ground level.
Floors above cold spaces - vented crawl spaces and unheated garages; any portion of the floor that is cantilevered beyond the exterior wall below.

With another blast of frigid temperatures in Worcester, you may be wondering how you can keep your heating bill under control.
There are plenty of ways to save money while heating your home. The most popular alternative heating method is with wood pellet stoves. They are small pieces of condensed wood that are stored in pellet stoves, and gradually fed into a fire.
Pellet stoves give you a constant flame, lots of heat, and requires little or no adjustments. They burn hotter than open fireplaces which means they give off more heat, and they are easier to install than wood stoves or gas stoves because they can be vented through any outside wall.
Pellets stoves are in high demand because they are easy to use, easy to maintain and easy to budget. Custom Insulation can help you decide what size pellet stove you need based on how much space you want to heat. Pellet stoves can heat an entire home, or they can supplement you oil or gas heating system. Additionally, pellet stove retailers can tell you how much pellets you need to buy in order to heat that space all winter. This way, you can plan for your heating bill rather than get surprised by it each time fossil fuel prices rise.
For those who are using pellets, it’s important to use high quality pellets, they burn hotter and create less ash, meaning less pellet stove cleaning.
A quality pellet is low ash, low moisture, and is considered a premium pellet. The price of low quality pellets may seem attractive at first, but higher quality is better.
Those pellets also burn cleaner and are better for the environment. Pellets are a renewable energy source and are a lot easier and nicer to handle than traditional firewood. This is another advantage of pellet stoves over wood.

Massachusetts is expecting another stretch of extremely cold weather this week. It is only mid-January and there is a lot of winter left. The arctic blasts we have been getting all winter long this year have made getting a pellet stove insert installed in your home a great idea.
The cold weather has meant that this winter has been a long season of heating costs so far. Pellet stove inserts are growing in popularity. That’s because they can be the main heating source for the whole home.
Pellet fireplace inserts cost typically cost between $1,000 to $3,000. However, they can pay for themselves in no time, especially if you have oil heat. Just the cost factor alone makes pellet stove inserts worth consideration. You’re looking at maybe $5 per day, the cost of heating a house with a bag of pellets. And, pellet inserts are easy to use and easy to maintain.
When it comes to buying the pellets, they’re available by the ton, which will keep your home supplied for quite a while. Additionally, the cost of pellets does not fluctuate which makes heating your home easy to budget.

Spray foam insulation is a smart choice in insulating your home. Spray foam insulation not only keeps your home warm, it also protects your home from mold and mildew, as well as insects and pests. Additionally, it is a safe way to insulate your home because it fire resistant.
When moisture gets into your home, mold can grow causing major health problems. Traditionally home insulation cannot keep the water out of your walls, ceilings and floors.
Spray foam insulation works against water because it expands to fill all open spaces causing a seal and it will not chip and crack over time. Water leaking into wall and floor cracks is leading cause of mold in basements. With spray foam insulation, these cracks are filled and sealed.
Cracks in insulation mean air pockets. Insects and pests are attracted to these air pockets. Spray foam insulation fills all the cracks and holes in your foundation walls and basement ceiling. Because all the cracks are sealed, no bugs can find a home in your walls.
Spray foam insulation expands and fills spaces and exactly fills the crevices and cracks around the basement or attic where it is installed.
Another advantage of spray foam insulation over traditional home insulation is that it is fire resistant. Having your ceilings, walls and crawl spaces insulated with spray foam protects you and your family from house fires that would traditionally travel through walls. With traditional insulation, not only is it flammable, there are air pockets around it. Spray foam is fire resistant and there are no air pockets to feed the fire.

Newly built homes have fantastic energy efficiency standards. Older homes, in fact most homes that are already built, don’t even come close to meeting those efficiency goals. The simplest way to make you older home significantly more energy efficient is to add insulation. In an existing home, this is easy to do with blown-in insulation in the attic.
Proper home insulation will keep your home warmer during the winter and cooler during the summer. Now with environmental concerns as well as a tightening economy, insulation is a great way to save energy and money. Especially in areas where it is cold like Boston and Worcester, the most effective solution to reduce heating bills is blown-in insulation.
One benefit to adding blown-in insulation is that it is adjustable. You can adjust to the R-value that you need. Add a few inches if you need an R-value of 15 or several inches if you need an R-value of 30. Blown-in insulation also gives your home a tighter seal because it fills all the cracks and crevices in the attic, making it very energy efficient. Blown –in insulation also has less allergens than fiberglass or batt.
Adding insulation to an existing home will have an initial cash outlay, however it will pay for itself over time. With lower energy costs and a warmer home, using blown-in insulation makes the most sense. For more information, contact Custom Insulation.

Remodeled homes definitely have their appeal, but more and more, homes with energy efficient and environmentally friendly features are becoming a priority for prospective buyers. Home insulation can increase the desirability of your home.
According to the National Association of REALTORS 2012 Profile of Home Buyers and Sellers, nearly nine out of 10 recent home buyers said that heating and cooling costs were somewhat or very important when considering a home for purchase.
Realtors know that consumer demand for greener homes has grown considerably over the past several years. Going green has proven to be more than a trend; many people now seek out this way of living and want homes and communities that are more resource efficient and sensitive to the environment. As energy savings and green building features are becoming more important to buyers, sellers and businesses, it comes as no surprise that consumers are placing a higher value on properties with those features.
Homes with the right home insulation have lower energy costs. Simple math shows how a higher energy efficiency rating offers homeowners the opportunity to save more money in heating and cooling costs alone.
NAR data shows how features directly affecting monthly energy costs are important to buyers. 39% of survey respondents reported that a home’s heating and cooling costs were very important when considering a home for purchase.
Regionally, buyers in the north and south placed a greater importance on heating and cooling costs, most likely due to the more extreme temperatures in these areas of the country. Nearly 60 percent of buyers who bought homes built in 2011 said heating and cooling costs were very important.
As energy costs continue to rise, look for those numbers to increase right along with them.
While new construction features like lot design, preparation and development are fairly set in stone in an existing home, there are many options when it comes to energy efficiency (improvements that will make the home less expensive to operate and more comfortable to live in), home insulation, water efficiency and indoor air quality.
While replacing HVAC or adding insulation may not be on the same level as a new kitchen or bathroom when it comes to appearances, they are definitely a smart way to use your remodeling budget. Not only will energy-efficient improvements start paying you back immediately, they will also make your home more comfortable no matter what season it is.

Heating a home is one of the largest household costs, and the best way of reducing this cost is with a better insulated home.
Shrinkthatfootprint.com claims that it is possible to have such a well insulated home against heat loss or gains that only the sun, our bodies, a few simple appliances, and a basic heat recovery system would be enough to provide all the necessary heat for a comfortable existence. Basically, if the insulation is good enough then you need never worry about heating bills.
A Leaky House – is the most poorly insulated example. It consists of solid walls, an uninsulated floor, single glazed windows, and lots of drafts. In order to combat the high level of heat loss the leaky house needs to generate quite a bit of heat to remain at a comfortable temperature.
A Modern House – is the typical new build house that many people own. It has insulation between the walls, in the loft and the floor, double glazing windows, and far fewer draughts. This all helps to drastically reduce the energy needed to heat the property.
A Passive House – is the most perfectly insulated home imaginable. All materials used to build it offer good insulation. It has triple glazed windows, and is so air tight that a ventilation system is needed to keep the air fresh. It estimated that most of the heat can actually be generated through a heat recovery system in the ventilation system.
The difference in heating bills for an average sized home in each class has been estimated to be $1,500 a year for the leaky home, $750 a year for the modern home, and just $100 a year for the passive home.
Unfortunately for those living in a poorly insulated houme, cost effective retrofits are difficult to achieve and it is far easier to create a well-insulated house during the construction phase of a new build.

Home insulation; most homes have it. But do they have enough. Winter is here and many communities around Worcester and Boston got their first snow of the season already. The best way to keep your home warm and to keep your heating costs down is to be sure that your home is properly insulated.
Attic insulation – Heat rises, and in an uninsulated home a quarter of the heat is lost through the roof. Insulating your attic is a simple and effective way to reduce the amount of heat leaving your home and lower your heating bills. Many homes already have some attic insulation, but the amount of heat lost and the energy savings gained will directly relate to the current thickness and condition of the insulation. If you live in a home that’s older than 10 years, it is probably time to check on- and add to- your attic insulation.
Floor insulation - Insulating under the floorboards on your ground floor could save you money. Although older properties are more likely to have suspended timber floors these can be insulated with spray foam insulation or blown-in insulation as it performs better between joists as it will take up thermal movement and cut down air movement around the insulation. Newer homes will have a ground floor made of solid concrete. This can be insulated if it needs to be replaced, or can have rigid insulation laid on top.
