French doors can add an elegant and classic look to any home, offering an easy flow through the home and linking outside spaces to the home effortlessly. French doors have been popular in British homes for a long time and the classic look will never go out of fashion. There are three options for homeowners in the modern market; French doors, Sliding Doors and Bi-folding doors. French doors are perfect for a medium opening, with two doors which open from the center to give the feel of a large, unobstructed gap. This gives a much wider area than a single door and provides easy access with no central bar or pane of glass, such as you would find on a sliding door. Sliding doors have become less fashionable in recent years and have been criticised for people walking into them and knocking them off their runner! Bi-folding doors are excellent for a large opening but are often excessive for a medium space as they are costly for a limited space.
There are significant differences in the 3 types of material used for French door manufacture each one has its own features.
Timber: The main issue with using wooden external French doors is that, if not properly sealed, timber will saturate or dry out. This “instability” is what causes timber French doors to deform. They can develop draughts from gaps surrounding the door when the wood shrinks as it dries out or sticks & jams when the wood swells as it absorbs water. However, with good maintenance, hardwood timber doors will last 40 or more years, much longer than other materials.
Aluminum: Aluminium French doors are a good option, being very light and strong. However, also
being made from metal, they are cold to the touch.
The metallic structure of the frame necessitates a thermal break between the inside and outside
surfaces. If this thermal break is not made well, then the frames will transmit heat, cold and even
develop condensation on the inner surfaces.
UPVC French doors: This material has such a lot of things going for it. Light, strong, cost-efficient and a natural
insulator, UPVC frames used for French doors offer the best features of all the other material
combined. Most uPVC doors will last 20 or more years, giving excellent value for money and with a
wide choice of colors on the market now, they are the most versatile. Most uPVC doors also come
with multipoint locking systems as standard, improving the security of your doors.
In addition, uPVC doors are very easy to look after. All that they need to keep them looking as good
as new is a wipe/wash clean. They will never need painting and should retain their colour. They are
not affected by bad weather such as rain, frost, and snow nor should the colour fade in strong
sunlight. The door will not warp due to a change in the air temperature and moisture as a wooden
Energy Efficiency and Insulation
The door should be well insulated to stop the cold getting in and the heat getting out of your home thus making them very energy efficient. If you have glazing in the door it should either be double or triple glazed. Another benefit of being well insulated is that they should reduce noise levels inside your home if you happen to live on a street that is busy with traffic passing by. A good indication that your door has a quality seal is that when you close it shut it should do so with a good solid feel.
To make the doors as energy efficient as possible, a standard UPVC French door is fitted with double glazed sealed units. To further enhance the performance, the sealed units can be filled with Argon gas and low-emissivity glass can be substituted for standard glass. Some companies are offering triple glazed windows as well but always look for the A+ rated windows as they will be the most energy-efficient available. The UPVC frames themselves are multi-chambered (much like a honeycomb), which also benefits the overall energy efficiency of the door set.

As mentioned previously, uPVC doors are often the most secure set of patio doors on the market. The security of French doors has, in the past, been subject to question. Modern French door designs have addressed previous criticism and can now incorporate security features such as:
1. Multi-point locks that engage at the top, bottom and sides
of the frame.
2. Deadbolts that secure the doors to the top & bottom of the
3. 5 lever mortice key locks on each door leaf.
4. Pinless hinges. 3 sets per door.
5. Internally operated thumb-turn locks (cannot be operated
from the outside).
6. Internally glazed & beaded so the glass cannot be removed
from the outside.
7. Toughened, tempered safety glass.
All these features mean that uPVC French doors are much more secure than their rivals and you can be secure in the knowledge that your doors are just as resilient as your hardwood front door! To make sure you are fully secure, buy a uPVC door with a British Standard PAS 24-1. This means that the door and frame, as well as the locking mechanism, have successfully gone through several physical tests.
Did you make any New Year’s resolutions this year? What did you resolve to do? If you’re like many folks, you may have resolved to quit smoking, to exercise more, or to keep in better touch with far-flung family members. Whatever resolutions you made (or even if you didn’t make any at all) we have a great suggestion to add to your list: make a commitment to do three things to make your life a little greener.
We’re not talking major, life-changing adjustments here. We mean making simple, but effective changes that have a real impact on your life, on the planet, and in many cases, on your wallet.
To get you started, we’ve put together a list of simple things that you can do to start or sustain a greener, healthier life. Pick three, and see what happens! Of course, there are hundreds of little changes you can make that result in greener living – we’ve compiled a few to get the ball rolling.
As much as I love to focus on interior spaces and how the design you approve and the materials you select can make a home both green and gorgeous simultaneously, the reality is that energy efficiency is a huge component of sustainable living. With the changing seasons, it’s time to admit that your home is not ready for the cold winter and spend an hour or two on the un-glamourous part of smart home ownership.
Here are 3 favorite options to help make your home ready for winter. They are an easy way to save around $100 per month this winter.
First – change the furnace filters. Unless you have changed them in the last 3 months, it’s time to do it. Starting the winter with clean, un-blocked filters is like starting the day with clean clothes. Except with a furnace, the dirtier the filters gets, the more it costs to operate, and the more polluting particles escape into your vents. All hardware stores carry a variety of filter sizes. Cost = a few dollars per filter. Benefit = cleaner air and savings on your gas bill. For those who like accessories, add this simple furnace whistle onto the new, clean filters and they’ll tell you next time they need to be changed!
Second – wrap the water heater. The benefits here are two twofold. If the water stored in the tank is kept warm, it delivers warm water to your faucets faster and requires less energy to do so. The result is a hot shower, faster and for less money. These blankets are readily available locally, or here’s an online option from AMConservation. Cost = less than $100 and they’ll last for years. Benefit = less water used waiting for it to warm up, and savings on your gas bill.
Third — block the attic stairs. We all know heat rises, and that hole in your ceiling is just pulling money out of your wallet. Literally. Ok, well not literally, but almost, it’s such a direct waste of money. I covered ours, and the temperature at the opening increased by 5 degrees immediately. Considering the pros estimate that each degree of heat represents about a 1% cost savings, the savings here will be noticeable.
So, three easy steps to make winter a bit more bearable, on your wallet, on your air quality, and on yourselves. No excuses!
A metal roof with built-in solar panels is the most energy efficient and longest lasting solar roofing solution. A metal roof will usually last in excess of 50 years, and solar PV panels usually last 30+ years with minimal loss of efficiency or or electric power production. The combination of the two creates a one-time green roofing investment that will pay for itself over time, and then it will produce free electricity. Such a smart combination eliminates the chance of roof leaks, since there are no roof penetrations, and gives a homeowner piece of mind and confidence in their green metal roof.
Why would you want to install PV solar panels with a metal roof, instead of installing it on the existing asphalt shingle roof? The answer is very simple; asphalt shingles last an average of 15 years, while your solar panels should last at least 30 years. That means that even if you install your solar panels over a brand new asphalt shingles roof, you will have to remove the whole solar system in 15 years, replace the roof, and then put the solar panels back onto the roof. With the installation costs of a solar PV system being about $2 per watt, and an average solar system size of 3 KW, you will have to pay an extra $6000 (in today’s dollars, before any inflation is calculated) to reinstall your solar panels, and another $1500-2000 to
remove the panels, so that the roof can be replaced. With today’s average solar system price of $9-11 including solar panels, inverter, all wiring, rack-mounting system, permits, installation, etc.), the removal and re-installation price amounts to about 25% of the total solar system cost.
A properly installed standing seam metal roof will easily outlast any asphalt shingles roof by 3 time or more, and it will also outlast a warranty period on any solar panels. When your solar panels get old, and start producing less electricity than what they were designed for, you will have an option to either keep the old solar panels or install the new ones (as a side-note – average efficiency loss of a solar panel is 0.5% per year or 10% over a 20 year warranty period). All your infrastructure will already be in place, and you can simply swap the old solar panels for the new ones. You may also have to swap the charge controller / inverter. In 20 or 30 years, as technology progresses, the efficiency of solar panels and inverters will be much higher, and the cost per watt will be considerably lower. At the same time you will still have your metal roof, performing at 100% efficiency – being leak free and beautiful, that is.
Solar panels can be attached to a standing seam metal roof in two different ways. One is to use a thin film Solar PV panel laminated inside the pan of a standing seam metal roof – a so called solar metal roofing concept, when solar panels are integrated with the roofing material. The limitations of solar metal roofing include lower efficiency (per sq. foot or sq. meter) of the solar PV laminates. Therefore you would need double the roof area to get the same number of kW of a solar system. Also the size limitation of each solar PV laminate (18 feet long panels) make it impossible to install them on roofs with a roof run of less than 18.5 feet.
A better way to install solar panels onto a metal roof is to use S-5 clips or mounting brackets, specially designed to add adequate strength and support of rack-mounting systems installed on standing seam metal roofs. S-5 clops are made of cast aluminum blocks, with stainless steel tightening screws. S-5 clips are attached to the ribs or locks of a standing seam panel, and provide great pullout ratio, meeting and exceeding Miami-Dade county building code requirements for wind uplift.
S-5 Solar Panel mounting clamps allow for a quick and inexpensive installation of the solar rack-mounting system. Solar panels can be attached directly to the clamps, or to horizontal / vertical rails. The overall cost of such solar racking system is reduced from about $1 per watt, to about 50 cents per watt, or less. Also, you do not have to worry about any roof leaks, as there are no roof penetrations, and all mounting hardware is attached to the ribs of the metal roof panels.
You can also get a double tax credit for your solar roofing installation – Your first tax credit would be a 30% tax credit for solar panels, and and another one – up to $1500 cool roof tax credit. An average cost of metal roofing materials will exceed $5000 per roof, so you will be able to get a full 30% cool roof tax credit. With today’s metal roofing prices for steel standing seam ranging from $15000-20000, a $1500 tax credit will save you about 7-10% off your lifetime metal roof.
CFLs have several advantages over incandescent light bulbs: they last from 8-10 times longer, use about 75% less energy, and produce 90% less heat while delivering more light per Watt. For example, a 25 Watt CFL provides about 1800 lumens, compared to 1750 lumens from a 100 Watt incandescent lamp.
CFLs have come a long way since their introduction. They provide a flicker-free, soft-white light and come in a variety of styles. The traditional “twist” bulb is the most popular, but if you need a more stylish version, consider the household style. This bulb is similar in design to a standard incandescent bulb but uses significantly less energy. The 3-way CFL is perfect for reading lamps or conversation areas where ambience is a factor. The globe style is designed for bathroom fixtures.
Here’s a groovy advantage – CFLs save you money! One 20 Watt CFL (replaces a 75 Watt incandescent bulb) will save you $66 dollars over the life of the bulb (based on $.12 KWH). Replace one 100 Watt incandescent bulb with a 25 Watt CFL and save a whopping $74 dollars over the life of the bulb (hey – that’s 21 extra Mocha Latte’s).
Not only are CFLs the smart choice – they’re hip too. The EPA reports that CFLs are the environmentally responsible choice. Replacing one incandescent light bulb with an energy saving CFL bulb reduced carbon monoxide emission to the atmosphere by 1,000 pounds.
According to the Department of Energy, as a nation we spend about one-quarter of our electricity budget on lighting, or more than $37 billion annually. And while traditional incandescent light bulbs are less expensive to purchase, they are much more expensive to operate. Incandescents aren’t such a bright idea after all (sorry – couldn’t resist).
