It’s an exciting experience when you finally decide to switch to solar energy. After plenty of research, you’ve determined that you want to invest in solar panels. You’re so excited that you’ve already started to research solar installers in your area. Still, one little question currently holds you back from making the move to solar: “What else should I do before asking for a quote?”

We suggest checking to make sure your roof is as ready for a solar panel installation as you are. There are three important questions you consider before you make the move to solar energy:

• What does your roof look like?
• What is the condition of your roof?
• How much shade does your roof get throughout the day?

Your answers can help you determine if it’s time to get quotes for solar panels. Let’s dig into each question, shall we?

What Does My Roof Look Like?

A quick inspection of your roof is a big first step in determining whether it’s ready for a solar panel installation. There are three major factors you should consider:

• The age of your roof
• The roofing material
• Potential obstacles for solar panels

Age of the Roof

The older your roof, the more likely it is that you’ll need to do some work before you invest in a solar array. If your roof will need to be replaced within the next 10 years, it’s best to replace it before solar panels are installed. This will save you from having to remove and reinstall them when the roof is replaced.

Roofing Materials

While solar panels are routinely installed on metal and asphalt roofs, some roofing materials, such as slate and Spanish tiles, require more care when installing solar panels. If your roof is made of a delicate material, you should talk to a professional roofer for their recommendation on mounting panels on your roof.

Potential Obstacles

Solar panels need to be laid down in straight rows. This means obstacles, such as vents and dormers, can limit how many panels can fit on your roof. A good solar consultant can potentially design around these obstacles, but it can still impact your overall solar potential.

What is the Condition Under My Roof?

Depending on the condition of your roof, you may need to replace it before you install new panels. Inspect your roof for the following signs:

• Damaged rafters or trusses
• Leaks or stains in the attic or on walls
• Mildew
• Dark, “dirty-looking” spots on the roof

If your roof is showing any of these signs or hasn’t been replaced in the past 10 years, consider getting a roof repair estimate from a professional. Shop around and see what you can find. If the area you want to install panels is inaccessible, consult your home’s blueprints for the structure of your roof.

How Much Shade Does My Roof Get?

Shade from trees and other buildings can limit the production of your system. Because of this, it’s best to avoid installing panels in shady areas on your rooftop, if possible. If necessary, trees can also be trimmed to optimize unshaded area on your roof. Use Project Sunroof to see an estimate of how much sunlight your roof sees each year and which areas of your roof would be best for panels.

Make Sure Your Roof is Ready for Solar Panels

A little preparation can make a big difference for your solar energy system. By considering three simple questions about your roof, you can put your panels in the best position for maximum production.

A decent pair of badminton shoes is essential for not only maximizing on-court performance, but also to prevent injury. The legs and feet are certain to experience a lot of stress when playing badminton, so it is important to carefully consider the different features and options. Let’s take a look at a few things that are essential in badminton shoes:

Soles

Most badminton shoes have gum rubber or rubber soles. For the players using a PU or wood court, the preferred option is the gum rubber soles. They give a very high level of grip on the court. Alternatively, the standard rubber soles are adequate for the cement based floors.

Also, there are shoes that have non-marking soles to avoid leaving a lot of marks on the floor from the fast movements from the back to the front of the court.

Ventilation

Proper ventilation is certain to be appreciated in shoes worn while engaged in a fast paced sport. A build up of sweat can lead to wet shoes which can easily develop into bacteria and fungi. Also, they will likely smell very badly after a short period of time. Ventilation in various places on the shoes will help to keep the feet cool and make the time on the court a lot more comfortable.

Cushioning

Badminton involves a lot of moving around and jumping, so shoes with excellent cushioning are certain to benefit. Good cushioning will ensure the body is given the desired impact protection from the constant movement. An area of the body that will see a lot of stress is the knees from the regular jumps or a lunge. But, with the right shoes, it is possible to rely on the cushioning to accept some of the load, and not entirely on the knees.

Weight

The light shoes for badminton are the most desirable option. With a need to constantly move around the court, the heavy shoes will only slow the player down after a short period. A typical weight is in the region of 250-350 grams. At this weight it will be easier to swiftly move across the court to strike the shuttlecock.

Ankle Support

In general, the badminton shoes are built with minimal ankle support compared to running shoes or trainers. Ankle support is useful for running shoes because the feet and legs need to be kept in a straight line. But, with badminton there is a constant need to move sideways, backward and forward. The preferred choice with badminton shoes is to let the ankles flex naturally, and they will develop flexibility and strength on their own.

As previously mentioned, trickle vents are an excellent way of reducing condensation in rooms that are poorly ventilated, as well as an excellent way of maximizing airflow. Most window systems are compatible with these vents, and even if the window frame is not compatible, the vents can still be fitted to it independently. Some may want to improve the aesthetics of the window, and in this case a window board receptor can be installed. These are compatible with most UPVC windows and provide an excellent look to the windows. Those who are still in the process of building their home should first ensure that the contractors hired have no problems fitting UPVC windows, before considering trickle vents or board receptors.

Let us get back to trickle vents however, and see what some of the advantages of having them installed are. It is well known that building regulations state that adequate means of ventilation is required in any home or building. It is also well known that poor ventilation in rooms can have consequences on the health of those living in those rooms. Proper air circulation is mandatory in all livable rooms of the house, as microscopic organisms contaminate the air, due to the moisture naturally produced in a home, as well as mould that starts forming from condensation. Living in a mouldy room where the air is contaminated with dust mites and other microscopic organisms is a major health issue, and proper ventilation is the only way to prevent that from happening. Such micro organisms can lead to lung conditions, depression, and even heart conditions, if left unchecked.

Opening the windows regularly is a good way to ventilate, and sometimes the only way to ventilate for those who do not have trickle vents, yet have sealed windows that prevent air from entering into the room. Previously, before sealed windows became common in most homes, ventilation was provided by the tiny gaps present between window frames and the building structure. Since that is no longer the case, a trickle vent is an excellent ventilation solution. These are usually placed at the top of the window frame, and can be controlled. This means they can be opened to allow fresh air in and polluted air out, or they can be closed. That sounds just like a regular window, but the advantage is that the vents can be left open at all times, even when away on holiday, as opposed to windows that should be closed when the house if left empty. Even those windows that have a night latch should be closed at night or when the house is empty for longer periods of time, due to the security risk they pose.

Also, unlike a regular window, a trickle vent does not contribute significantly to heat loss. That means it does not really matter if it is left open at all times, because the difference in temperature is negligible. There are no disadvantages from installing such a vent to the window frame, and they can even be made to work along mechanical fans, for when more ventilation power is needed.

With a long list of important advantages such as improved security, reduced health issues, and reduced heat loss, trickle vents are certainly something worth considering. Most UPVC windows are compatible with them, and good trickle vents have an excellent design and are completely unobtrusive. Since building regulations state that proper ventilation is required in livable spaces, such vents are not only the cheapest solution, they are also the easiest to install. Just about any window board should be suitable and installing the vents should not be complicated for good contractors. As long as they know a thing or two about fitting UPVC windows, they probably also know how to install a trickle vent. After the successful installation of the vents though, a definite improvement in the quality of air should be felt, especially if the room had no ventilation before, except for when the window was open. Especially those who suffer from allergies should feel a major improvement in the quality of their sleep, and reduced allergy symptoms. Remember that proper ventilation can truly be a life saver, in some cases.

Coronavirus are a type of virus which causes common colds, but can also cause more serious diseases such as SARS, MERS, or COVID – 19. The virus is only about 0.025 µm in diameter, far smaller than the human eye can see even with the best optical microscope. In comparison, a fine human hair is about 40 µm in diameter. When people talk, cough, or sneeze they eject small droplets which vary greatly in size but the average is about 1 µm. Each small droplets can hold hundreds of thousands of viruses and the droplets can persist in the air for several hours.

This image of a coronavirus taken by an electron microscope shows small structures on the surface which look like crowns. When the virus encounters a human cell, the crown attaches to the cell’s surface and injects its own RNA into the cell, which then takes over the cell mechanisms and produces copies of the virus. They eventually cause the cell to burst which can release up to 50,000 new viruses.

COVID-19 Virus is a new virus in humans which entered the population for the first time late in 2019. The virus cannot live long outside a human host, and the main vector for its transmission is those who travel to and from infected areas. We have little natural immunity to the virus and there is no proven treatment or vaccine for the virus. About 97% of those infected recover within 14 days, but particularly severe cases must be put on a ventilator to keep the patient breathing until the virus runs its course. The virus is most lethal for the elderly and those with compromised immune systems.

The symptoms of the virus are headaches, fever, pink itchy eyes, coughs, sneezes, sore throat, tightness in the chest, difficulty breathing, inflamed toes, and loss of smell or taste. The incubation period after exposure is from 5 to 14 days. People exposed may transmit the virus to others before they experience symptoms. However, some people with the virus may never have symptoms, yet still be able to transmit the virus to others.

The virus is transmitted by direct contact between individuals from small droplets ejected when an infected person talks, coughs, or sneezes. The social distance of 6 feet is usually enough to prevent the virus being transmitted directly. However, small droplets from coughs or sneezes may travel much further than 6 feet and may contain hundreds of thousands of viruses. The droplets may persist in the air for several hours. They eventually settle on surfaces where the virus may live for up to several days, depending on the type of surface. For example, the virus is found to exist for a day on cardboard and up to three days on tile or plastic.

The virus infects a person by entering through their eyes, nose, or mouth. It may happen from being near an infected person, particularly if they are coughing or sneezing. Small droplets that settle on surfaces are transferred when you touch the surface and then it may infect you when you touch your face. Once on your hands, you will transfer the virus to everything else you touch until you wash your hands or kill the virus with hand sanitizer.

The best precautions aim to keep the virus from being transmitted from person to person. From what we know about the virus, the following guidelines have been developed to keep it from spreading:

• Avoid close contact with people who are sick. Stay home as much as possible, particularly if you may be sick.

• Keep a social distance of at least 6 feet from other people when you are in public.

• Avoid touching surfaces in public places. Assume anything you touch may be contaminated.

• Wash your hands often for at least 20 seconds with soap and water or use sanitizer.

• Avoid touching your face, particularly rubbing your eyes.

• Wear a mask when in public, primarily to keep you from infecting other people. Remember you may spread the virus even though you have no symptoms.

• Avoid traveling to and from areas which have high levels of infection. Human movement is the main vector for spread of the virus.

• Avoid gatherings, particularly those which have more than 10 people.

For the future, most states have issued orders based on the precautions above in order to keep their citizens safe. However, if the orders remain in place too long they will hurt the economy, but if they are relaxed too soon we may experience a second round of the virus. This would prolong the pandemic and hurt businesses even more. Most states, sometimes under political pressure, are relaxing the guidelines stepwise in order to allow businesses to open while keeping an eye on the of infection rate.

No matter what your state orders, it would be a good idea to follow the precautions above until the OK is given by healthcare professionals. The decision up is up to you. Please follow the guidelines to keep yourself and others safe.

The pie funnel, also known as pie ventilator or pie bird, as the Americans like to call it, is a late Victorian utensil. They were designed to prevent the juices spilling onto the pastry or the floor of the oven and also to support the pie crust and stop it from sagging.

The first recorded pie funnel was manufactured in 1880 by Dean and Morris and it was made in three sizes. Since then 44 different patents and registered designs have been recorded in Britain and many of these can still be bought today. One of the earliest recorded figures was a blackbird, registered in 1933 in Australia by Grace Seccombe as a Pie Crust Lifter. A J Wilkinson (Clarice Cliff) registered a blackbird funnel design in 1936 and many of these were produced, including the all white wartime version – some were stamped Wilkinson, Newport Pottery or, later, Midwinter.

Before the appearance of the pie funnel people would have used an egg cup or even a stick of macaroni. As pies come in different sizes and depths so do funnels and they were often produced in sets. Among these sets are the Adcock Crust Support, Ventilator and Fountain. These early funnels often had wide chimneys for venting the steam from beneath the crust, but also for adding additional stock to the pie during the long, slow cooking process.

If you want to collect pie funnels you are in luck as once upon a time every household in Britain would have had one or several of these. As diet and cooking styles have changed over the last twenty years the pie funnel is no longer an everyday object and is probably stuck somewhere at the back of a cupboard or drawer.

Some pie funnels have fetched quite high prices but you should be able to start a collection for a small amount of money. Check out your local auctions and car boot sales and you should be able to get some of the plain pie funnels quite cheaply. You might also want to check out the internet auction sites as these are useful for researching prices.

Some of the famous china manufacturers such as Spode, Royal Worcester, Denby, Shelley and Grimwade have all produced pie funnels on a commercial basis but it was Grimwade that produced the widest variety of designs, five of which are patented or design registered. Among them are the ‘figural elephant pie funnel/ring holder’, which was produced in white and grey, to the ultimate ‘Bleriot Pie Divider’ produced in three different sizes, which separated the pie dish into two parts so that two different meats or fruits could be baked in the same pie. Each of these dividers came with their own specific patented pie dish.

‘The Improved Pie Funnel’ was produced by Grimwade and it is quite rare and it sold so well that an updated version was produced and named ‘The Improved Popular Pie Funnel’. These came in various sizes, advertising early grocery and china shops as well as department stores around the world, from T W Robinson Co Ltd of Moose Jaw in Canada to Ritchies of Dunedin in New Zealand as well as from all over the UK.

While the majority of pie funnels are made from pottery there is also quite a selection made from Pyrex glass, aluminium and plastic. The majority of the early examples were produced commercially by larger potteries that manufactured a wide range of white ware, but later the smaller potteries produced limited editions of real works of art. In the forefront was Stuart Bass, who has produced over 300 different designs since the mid-1970s.

A book called British Pie Funnels has been produced to try to fill in some of the gaps concerning the traditional British pie funnel as there has been little written on the subject. This provides a handy background for any new or experienced collector and some of the illustrations should prove useful when identifying the various pieces.

Having fresh air along with adequate ventilation serves many more purposes than just the well-being and comfort of occupants. Although a supply of clean air is very important, these systems are also capable of providing condensation control along with the removal of airborne pollutants. In this article we will take a closer look at industrial ventilation systems.

The word ventilation basically means the movement of air from the outside of a structure or building to the inside, and there are many different types products available in order to handle this, from fume extraction systems to more specialized applications such as welding fume removal.

Industrial units will help with the controlling of workers or employees being exposed to various airborne toxic chemicals or from flammable vapors by moving the contaminated air away from the area and subsequently replacing it with fresh clean air. It is the most widely used way in which companies decrease exposure to harmful air contaminants in their workplace. These systems also can remove such things as oil mist and dust, fumes from solvents, etc. And will exhaust these outside.

Generally, the maintenance of as well as troubleshooting of this kind of system will normally be handled by a qualified engineer or a firm that specializes in this field. The amount of worker exposure to certain contaminants is tightly controlled by occupational health regulations, and some of the conditions include lowered oxygen levels, levels of airborne contamination that has risen above permissible exposure limits, and also explosive limits concerning flammable vapors.

Some of these systems will operate on the principle of moving the air from areas of high pressure to low pressure and this is accomplished by a fan which will draw air through the ventilator, and these are normally found as close as possible to the contamination source, therefore being able to capture it before it is actually released back into the work area. It usually has several basic elements, including a hood, the duct, a cleaning device and also the fan and exhaust stack.

With any of these kinds of units, the fan is one of the most important. They should be the appropriate type as well as size in order to make everything work effectively, and should also provide sufficient air pressure difference to be able to carry everything efficiently. There are two main types, centrifugal and axial, and both are very effective with rugged blades.

If your existing unit seems to be not functioning properly, there are a few simple checks that can be made without having expert help, and these may include such things as checking for fan belts which are broken or are slipping, ducts that may be clogged with dust, dampers in the duct work which may have closed up, holes or cracks in the ducting as well as air cleaners that may have become clogged up.

Usually most of these problems can be avoided by having periodic maintenance and servicing. There are many companies that provide industrial ventilation as well as heating and cooling for homeowners and most can be found in your local yellow page directory.
