Insulation of the Past

For as far back as history goes, the earth has experienced four distinct seasons. Some areas have always experienced more extremes in terms of temperatures and therefore had to find ways to maintain a comfortable living environment. Insulation has been used throughout the centuries to keep heat in and cold out or vice versa. Here is some history:

Several nations that lived in particularly hot climates would construct homes with thick walls. Thicker walls would insulate against the heat and provide a cooler and more temperate indoor environment in which to live. This is evidenced in many of the ancient Mayan ruins in Central America. The Egyptians also used these construction methods to keep out the desert heat of the Sahara. The homes were characterized by low roofs and small windows so the heat couldn’t easily enter and remain in the homes. The Ancient Greeks probably made some of the more significant discoveries in terms of insulation. With regards to building construction, they used cavity walling to insulate the buildings. Cavity walling has a gap between two walls which traps air and moderates the temperatures. In other words, during the hot summer months, the cavity walling would help keep the warm air out and in the cooler winter months, it would help keep the warmth inside the homes. The Romans also picked up on cavity walling and used it as a method to insulate their homes. In addition, they used materials such as cork to insulate hot water pipes so the heat from the pipes would not transfer to the surrounding walls and floors, causing them to crack. Fabrics were also used as additional insulation. Scraps of cloth would be tucked into window frames to keep out the desert dusk or the icy European cold. Rugs made from animal furs were used as carpets and thick linen drapes were used as curtains. Elaborate tapestries were hung on walls and helped to manage some of the moisture buildup in the stone buildings. The tapestries also helped moderate the draughts that could sometimes cause an added chill.

During the Industrial Revolution, insulation became an integral part of many designs. Steam power was driven by coal-burning furnaces and asbestos was the main type of insulation used because of its flame-resistant properties. Interestingly enough, asbestos had been used by the ancient Greeks and Romans as insulation and they had dressed their slaves in it. Even though the Greeks had noted that it seemed to cause lung disease in those who were exposed to it, the industrialists seemed oblivious to this fact. For more than a century, asbestos continued to be the main form of insulation. It was only in the mid-1970s that the harmful effects of asbestos were finally properly documented which caused industries to consider other forms of insulation. Fiberglass batting was then widely used in building and construction projects and is still used today.

14 Ways to Use Beer Around the House

At the beginning of the week we asked if your beer was green. This post is about how you can be green with your beer!

Most of us don’t usually think of beer as an earth-friendly alternative to improving our gardens and lawns or dealing with a host of pests. However, if you can bring yourself to part ways with your favourite brew, or at least invest in some of the cheap stuff, you’ll be surprised by beer’s many uses.

1. Trap slugs and snails: Place dishes or jars of beer around your garden, especially in the evening. In the morning, the slimy critters, which have been drawn by the beer’s aroma/fermentation, will have drowned. The beer can be reused until it evaporates for garden pest control.

2. Trap fruit flies: If you keep a compost pail in your kitchen, you will also likely have fruit flies. Just place a jar or can of beer on the kitchen counter. Cover the top with plastic wrap or paper, leaving a small opening for the flies to get into. The fruit flies won’t be able to get back out.

3. Distract bees and wasps from your outdoor gathering: Beer placed in cups around the outskirts of your picnic or barbecue will attract bees and wasps. It’s not a long-term wasp control tactic; it’s more like placing difficult relatives at the furthest table.

4. Get rid of mice: If you don’t have a cat, a small amount of beer placed in a pail will help take care of a mouse problem, especially if you prefer to capture mice in a humane fashion. Just put an inch or so of beer in the pail, place some type of ramp, such as a piece of wood for the mice to crawl up. The mice fall into the pail and then you can remove your inebriated mice to some place outside.

5. Cockroach trap: Put a piece of bread soaked in beer in a jar. Put Vaseline around the lip of the jar. Roaches are attracted, get in, and can’t get out.

6. Fertilize your gardens: The sugars in beer are also enjoyed by your garden vegetables and flowers.

7. Fertilize your indoor plants: Yep, they like beer too. You don’t want to overdo it with indoor plants since they are contained and not subject to the cleansing distribution of rain. Use flat beer, just a small amount at the base of the plant.

8. Get rid of brown spots in your lawn: The acids in beer kill off fungi and pests, and the fermented sugars feed the grass.

9. Stain removal: Instead of pulling out a chemical cleaner when you’ve dribbled tea or coffee on your clothing or rug, soak the stain in beer. Let the beer sit for awhile then dab with a clean cloth. Wash well with soap and water once the spot has soaked. Always spot-test the fabric first.

10. Spruce up wooden furniture: Rub flat beer gently onto furniture using a soft cloth. The beer will help restore some of the polish and colour.

11. Clean gold jewellery: Similar to how you would use commercial gold-cleaning chemicals, just place your gold jewellery in a dish of beer. Let it soak, then remove, rinse, and gently polish with a dry cloth.

12. Polishing brass pots: Using a soft cloth, gently rub beer onto the pot. Let the pot sit for awhile, rinse, and dry with another soft cloth. The acids in beer work wonders on most metals.

13. Loosen rusty bolts: Using beer to loosen bolts is a bit “Macgiver-ish”, but the acids in the beer may dissolve enough rust to allow you to get them loose.

14. Insulation: Lastly, for the truly adventurous and creative, if you use full, unopened cans of beer in construction of walls, the beer absorbs the cold and won’t freeze in temperate climates (due to the alcohol content).

Is Your Beer Green?

There is a lot of pressure from consumers on big companies these days to go green. So why has the environment been a big green blind spot in brewery marketing?

The Canadian beer industry is known for their model of recycling efficiency, however the vast amount of water used in the manufacturing process and large amounts of fuel required for transporting, are not to be bragged about to advocates of green living.

It wasn’t until this year that Canadian Beer brands have begun to step up.

In April, Labatt’s Alexander Keith’s beer unveiled its Keith’s Green Initiative, whereby drinkers who purchased a specially marked case of the brew and then logged on to the brand’s Facebook page could help drive a total of $75,000 in donations to one of four environmental charities.

Next week Molson Canadian will wrap up its Red Leaf Project , a summer-long volunteerism initiative involving shoreline cleanups, tree planting, and the restoration of urban parks across the country.

Many large breweries claim to be waiting for market research to come in, to evaluate what is important to their consumers before making any drastic changes. However, a number of small craft brands have already made deep commitments, driven as much by their handmade aesthetic as by admiration for green heroes.

In downtown Toronto, the operations of Steam Whistle Brewing use a host of environmentally friendly services, including the alternative energy provider Bullfrog Power, deep lake water cooling provided by Enwave, steam heating, and a proprietary green bottle of thick glass that can be refilled up to twice as many times as the industry’s standard bottle. In 2007, it began telling customers about these green initiatives. And a few months ago, it introduced a new truck to its vintage fleet, a 1958 Chevy Apache dubbed “Retro Electro,” that had been retrofitted to run on electric power.

Some U.S.beer companies are going even further in embracing sustainable practices. In the fall of 2009, a pair of entrepreneurs opened Mother Earth Brewing in Kinston, a city of about 23,000 in eastern North Carolina whose downtown needed some tender loving care. They bought a few city blocks and renovated the existing buildings with a sharp focus on the environment, using a combination of blue jean insulation and soy-based spray foam insulation, installing a six-kilowatt solar array on the roof that provides enough energy to power their tap room, and constructing a cistern that captures rainwater for use in irrigation, toilets, and watering plants.

So the future of beer is starting to look greener. Hopefully the trends of those currently pursuing environmentally friendly initiatives will encourage others to do the same.

Phantom Power

Electronic devices left plugged in, even when turned off, still draw power. That’s called phantom power or standby power, and it’s costing you money. It’s also costing our planet even more with wasteful carbon emissions. Plug the following electronics into a power bar with a timer or auto shut-off and make sure they are off during periods of inactivity. For example: television, home theatre system, computer, monitor, printer, scanner, rechargeable devices (MP3 players, cell phones, battery chargers etc.), game console.

By reducing this unnecessary power use, you could help save up to 15% on your electricity use.

Easy Tips for Saving Money on Your Home’s Energy Bills While You are on Vacation

Its summertime, which means many of you will be (or already have been!) hitting the road and travelling to destinations afar! Before heading off, take a moment to think about your home’s energy consumption. Just because you aren’t around, your home is still using energy and you’re still paying the bills.  Fortunately, there are many small preventative measures you can take to conserve energy while you are away:

-For increased security, use timers on light fixtures inside and outside your home. Using timers is much less costly in the long run than leaving your lights on all day. Fluorescent lighting requires special dimmers or timers, so make sure you use the correct ones.

-Your refrigerator is an electricity hog. If you’re going to be away for a long period of time, consider emptying and unplugging it. Or better yet, have your old, inefficient refrigerator picked up. To learn how to qualify and book an appointment, visit  FRIDGE & FREEZER PICKUP

-If you spend a long time away from home during the coldest months of the year, set your thermostat down. In the winter set it at 18°C and if you’re away in the summer set it at 28°C.  A programmable thermostat is a great way to change settings automatically. There are programmable thermostats for central heating and baseboard heating.

-If you have a pool, make sure it’s covered and that the timer on the pool pump is set

-Electronic devices left plugged in, even when turned off, still draw power. That’s called phantom power or standby power, and it’s costing you money. It’s also costing our planet even more with wasteful carbon emissions. Plug the following electronics into a power bar with a timer or auto shut off and make sure they are off during periods of inactivity. For example: Television, home theatre system, computer, monitor, printer, scanner, rechargeable devices (MP3 players, cell phones, battery chargers etc.), and game console

By reducing this unnecessary power use, you can help save up to 15% on your electricity use!

Don’t Let This Happen to You

 

When the time comes to choose an insulation contractor for your home, you will find that there is no shortage of companies and contractors available. Therefore, it is important for you to do your research before making your selection. There are a lot of contractors out there that will do a fabulous job of talking the talk; however, walking the walk is an entirely different story.

 

These images were recently brought to the attention of a Great Northern Insulation Sales Representative by a homeowner in London, Ontario. This homeowner had hired a local contractor to complete a retrofit job with spray foam insulation. The company that performed the installation advertised their solution as an air seal, vapour barrier that fills all cracks.

 

The images show the completed work. Note the staining left on the outside brick and the questionable installation techniques. Insulation experts know that retrofitting these walls with a cellulose drill and fill would have been the proper choice under these circumstances.

 

When choosing someone to insulate your home, do not become victim to flashy sales pitches. When you do your research, find a company with real knowledge, and the experience to back up that knowledge. Hire someone that will do the job right the first time. At GNI, we back all of our work with a Customer Promise that includes a money back warranty, a product warranty, a sustainability warranty, and a satisfaction warranty. We value your business. Let us prove it to you.

20 Ways to Save Energy and Stay Cool This Summer

Summer 2011 has already shown record high temperatures. You want to stay cool and comfortable in your home, but cranking the A/C full blast means higher energy costs. The question you’re asking is how do I stay comfortable without breaking the bank? Fortunately there are many small changes a homeowner can make to cut costs while maintaining comfort.

1) For a lifetime of savings and increased comfort, upgrade your home’s insulation. In the summer, good insulation keeps cool air in just as it keeps warm air in during the winter.

2) Buy an Energy Star-rated programmable thermostat for as little as $25. When the house is empty, the thermostat could be turned up and set to have the temperature drop to more comfortable levels by the time you arrive home. Just doing that can cut energy expenses by 10 per cent.

3) Keep the thermostat at 25°C when you are home and 30°C when you’re away. Based on a 2,400-square-foot house, the savings-per-degree equals $4, according to Georgia Power in Atlanta.

4) Replace furnace/air-conditioning filters on a regular basis

5) Close blinds, curtains and shades on the sunny side of the house

6) Use energy efficient lights that produce less heat and get in the habit of turning all lights off when you leave a room

7) Replace older air conditioners or central-air systems (long term savings)

8) Use a ceiling fan to circulate air and create a cool breeze

9) Turn on the exhaust fan when you are cooking to get rid of hot air while you’re cooking

10) Use the BBQ or a microwave rather than your oven or stove so as not to generate unwanted heat in the home. The California Energy Centre advises that microwaves use two-thirds less energy than a stove does.

11) Take lukewarm showers and baths to avoid humid air, which holds heat.

12) Make sure you have the appropriate sized dehumidifier for your home. They can be a big drain on power.

13) Let hot items cool down before placing them in the refrigerator, so it doesn’t have to work as hard to cool them. Also note, the more densely packed your refrigerator is, the less cool air that will escape each time you open the door

14) Use a dishwasher. According to TreeHugger.com, dishwashers use half the energy and 1/6 of the water that washing by hand does. Letting dishes air-dry saves electricity.

15) Use the warm or cold water settings to making doing laundry more energy efficient. Use cold water to rinse clothes

16) Line-dry clothes whenever you can. When you run the dryer, do full loads, use the moisture-sensing setting, and clean the lint trap after each use

17) Unplug phones and chargers; turn computers and printers off at the power strip because most new electronics use electricity even when they are switched off.

18) Turn your water heater down to 50°C to save even more money on your electricity bill.

19) When baking, Georgia Power says, avoid opening the oven door, which lets out 20% of the heat. Use a timer.

20) When cooking on top of the stove, use pots and pans that match the size of your burners, which brings more heat to the pan and less to the surrounding area.

Giant Beehive Looms over Parliament Hill

If you looked at this picture and thought to yourself, something just isn’t right here, you are correct!

No, this giant beehive is not actually looming over Parliament Hill, and no, this isn’t a real beehive at all. Believe it or not, this synthetic replica is made from spray foam insulation!

It is a creation made by Uta Riccius for the project titled The Home Show, on display at Blink Gallery in Ottawa from July 21-24, 2011. The idea behind the artwork is to display what it might look like if parks were eradicated and all forms of natural environs were replaced with more urban, man made fabrications, showcasing how species would have to adjust to the surrounding changes.

Will spray foam be for more than just insulating in the future? Only time will tell!
