When planning and designing a new pergola one of the main construction considerations is selecting the type of roofing material you want for your pergola in line with your needs. There are a number of different types of roofing available including polycarbonate, colorbond steel, tiles and opening roofs.

The first point to consider when making your selection is that the more light you let in, the more heat comes in. The catch being of course, that you need more light in winter and less in summer. There are a few ways around this problem, firstly you can use a combination of polycarbonate and colorbond steel incorporating 2 or 3 sheets of polycarbonate inserts and having the rest of the pergola roof in colorbond steel. This will effectively still let the light in that you need and the pergola climate underneath will remain comfortably cool. Another alternative is to have colorbond steel on the west side of the pergola and polycarbonate sheeting on the other, if the pergola has a gable roof.

With the polycarbonates there are a number of different qualities and light/heat factors available. Some polycarbonates let more light in and others less heat. Within the Laserlite range, there are over 20 to choose from. Polycarbonate also comes in many profiles such as Greca, Roma, Trim deck and Multi-wall System.

If you have a larger budget then an opening roof may be ideal, in this instance you can control how much light and heat you let in. In winter you can get all the winter sun by angling the open blades towards the sun and in summer just close the roof off. In the event of rain whilst you are out, the rain sensor will automatically close the opening roof for you.

Another style of pergola roofing to consider is an insulated roof with polystyrene in the middle, a colorbond roof at the top and a stucco finish on the bottom. With excellent insulation properties this style of roofing is often used for cool rooms. Of all the pergola roof coverings this one will keep out the most heat. The only downside is that it’s extremely hard to install light panels into this type of roofing.

Depending on the type of materials and roof design of your pergola it’s often possible to change or reposition some of the roof sheets if your pergola is too dark or too hot.

Fortunately with the emerging trend of the sophisticated pergola in outdoor entertaining there are a large range of materials and colours in pergola roofing to enhance your existing facade and to compliment your entertaining style.

Roman architects designed a central heating system called a hypocaust. The word, hypocaustum means “heat from below.” The raised floors were held up by short pillars and spaces beneath them and inside the walls were heated with the hot smoke and air from the fire chamber. Walls were fitted with ceramic box-shaped tiles that served as flues to channel the burned air and smoke to the outside, as well as to warm them. The more warmth needed, the closer to the hypocausts they were located.

It was a pretty expensive and labor-intensive method, so hypocausts were reserved for public baths and upper class villas. In about 25 B.C. Sergius Orata figured out how to cut down on the overhead by putting the male and female bathing rooms close to the hypocausts and right next door to each other.

Korean traditional architecture uses an Ondol. This underfloor heating method depends on direct heat transfer from a wood fire maintained underneath a thick floor made of masonry. From the central firebox or stove area, usually accessible from the kitchen or master bedroom, a system of horizontal channels spider out underneath the structure. A chimney on the opposite side of the building from the firebox ensures a decent draft system.

One of the Korean twists is that while traditional masonry is used for the channels and to support the thick floor, they added an additional layer of something impervious to smoke and fumes, such as layers of stone slabs, clay and oil paper. The system works well and is in used today in many of their buildings, notably in an orphanage.

When American missionaries discovered small children sleeping on pallets and babies sleeping in boxes on the floor, they went to great lengths to obtain thousands of cribs. Even after their arrival, the well-meaning folks were baffled to find the children were still sleeping on pallets and babies were still in boxes on the floor. Only after considerable questioning did they figure out that it was the best way to keep the little ones warm since the floors were warmed in the traditional manner.

Today’s furnaces and forced air ventilation systems provide the latest in safe, efficient central heating. Filters ensure that pollutants from the outside are kept at a minimum and the closed heat production part of the system either confines or eliminates any potentially toxic substances.

We’ve come a long way, but the level of comfort we enjoy today stands on the shoulders of some pretty smart cookies who lived a very long time ago.

Reading books and listening to CD’s is a very long drawn out learning process and even the most studious of people can find it hard going. Going to college is another option. If you’ve got the spare time and a local college that runs courses you may choose to learn there. These courses generally run for a couple of hours per week for the school year with breaks at term’s end. College is a good way to learn but you still have to have the motivation to attend after a hard day at work.
So what is the alternative?

Why not take a holiday specifically to learn the language?

Italian is the language of love, and the country is one of magnificent beauty so why not encapsulate both aspects and take a learn the language holiday to Italy.
The locations are varied, learning holidays are held all over the country so it’s up to you to choose what else you’d like from your holiday other than learning the language.

Depending on the season you could go to Milan or Turin in the winter and do a little skiing, in the spring time go walking in the mountains or in the summer just go sight seeing. Italy has so much to offer the tourist apart from the obvious city locations. Why not learn in the beautiful old town of Alghero on the magnificent island of Sardinia You can relax by the pool, go to the beach, walk in the mountains or visit the archaeological sites scattered around. All these activities can be fitted in around classroom time.

The class room time generally also includes Italian culture lessons on such things as Opera, art and Italian history all of which will help you understand the make up of the language.
Generally class sizes are small and divided into ability levels. You should have no worries about being put into a class of fluent speakers if you can’t utter a single word of the language.
Usually students are accommodated in private homes, student apartments or hotels for as long as they are enrolled on the course.

Evenings may include cultural trips and meals out including specialties from local producers. You would generally spend evenings with the rest of your study mates but if you’d rather not then there is no pressure to conform.

Learning can be daunting at any age but as an adult the fear of failure for some people is just too much but on a learning holiday to Italy everyone is in the same boat, everyone is there to learn and make the same mistakes, and hopefully have some laughs along the way.

With so much to learn about and such a beautiful language to learn where else on earth would you want to learn the language of love other than the most beautiful and romantic country on earth, Italy?

What would you think if we said that a home could have:

* Heating bills 35%-60% less.

* Weather resistance that will stand up to hurricane force winds, and is rated to withstand earthquakes.

* The ultimate fire resistance insofar that some insurance companies decide to give a 20% (or more) discount on a homeowners’ policy.

* Healthy indoor air quality, essentially free from dust and pollen.

* A guarantee to never get dry-rot, or be infested by termites or carpenter ants.

* Recycled material components that save in average 15 trees per home when constructed.

* Reduced exterior wall sound transmission by more than 65% so barking dogs, lawn mowers, and even airplanes are reduced to a whisper.

* The most amazing thing of all, is that this technology is available right here, right now and it costs only a little more than a conventional wood built house.

The Magic of ICF’s……

The big secret that more and more builders, architects, engineers and homeowners are beginning to uncover is the new advances in concrete homes constructed using Insulating Concrete Forms (ICF) construction technology.

Insulating Concrete Forms are lightweight, highly durable foam blocks or forms composed of an expanded or extruded polystyrene, and recycled materials.

Raw plastic beads are molded into one of several basic form types. Some of these forms look like hollow blocks that you stack and interlock like big “Lego’s”. Others use panels that are held at a constant distance apart by a series of plastic ties.

Either way, the product is stacked in the shape of your home, reinforcing steel is placed inside, and concrete poured in between to create a solid, structural wall.

The Insulating Concrete Forms remain in place after the concrete sets, and function as thermal and acoustical insulation, an air and vapor barrier, and exterior wall sheathing. Your finished wall is basically 6″ +/- of reinforced concrete with 2″-3″ of dense foam insulation inside and out, resulting in a rock solid, 12″ thick, super-wall!

The integral, permanent insulation allows builders to construct ultra efficient walls in a fraction of the time required to build walls out of wood or steel studs.

How is an ICF Home Construction More Environmentally-Friendly?

In so many ways; ICF home construction reduces the consumption of energy. These are the most air-tight homes on the market. The concrete absorbs solar heat and slowly releases it so heat is distributed evenly throughout the home. The average energy consumption reduction is 35-60% below conventional wood frame houses. The houses use fewer natural resources to heat them and they will last quite literally for centuries.

ICF walls conserve forest resources and their energy efficiency reduces fossil fuel consumption. It’s estimated a 2,000 square foot home saves up to 15 large trees when compared to conventional construction. Concrete is inert, non-toxic, and produced from abundant natural and recycled material.

Lower noise from the outside world and the air exchange system all contribute to a more peaceful and healthy environment for the occupants of an ICF home.

Disadvantages of ICF construction:

Cost; expect to pay 5-10% more for an ICF home depending on where you live.Where ICF homes are popular the cost will probably be a little cheaper.

Even though ICF construction is very durable and Code approved, it might take a little extra time to get your plans through the building department (unless they are familiar with the particular system that you are using).

ICF construction requires subcontractors to do certain tasks differently. Wiring, heating, plumbing, and drywall will be different than in traditional construction. This might cause prices to be higher or occasionally, difficulty in finding sub-trades that have experience working in an ICF home.

The ICF industry is growing rapidly, and in the last few years we have completed projects in many different townships and municipalities. There are very few building departments left in Southern Ontario where they are not familiar with the ICF building process.

Summary:

* ICF homes are a superior system to wood framed or steel framed homes.

* Once the exterior walls are poured they are ready for finishing (on the inside and out).

* They are extremely durable and they don’t cost much more than a traditional framed home.

* Finding subcontractors may be a challenge, but if you are planning to live in your home for many years, ICF homes are the only choice to make.
