Snow Vs. Your Metal Roof

In climates where heavy snowfall and high moisture are the norm, one of the best solutions to protect a home is a metal roof. These carefully designed homes are made to stand the test of time winter after winter against all the brute force snow can wear against the top of a house. Sheet metal roofing is an excellent choice as it allows snow to slide off before becoming a major issue. Other options allow the frozen water to build up and deteriorate roofing material or collapse a building. However, not every metal roof is made the same. These three mistakes can compromise the benefits typically associated with sheet metal roofing.

Shallow Slope
One of the key aspects of a metal roof is the ability to prevent snow from piling up and weighing down on your home. Unfortunately, many roofs are not steep enough to take advantage of this necessary component. Unless your roof is pitched at least one inch per square foot, it remains possible for heavy frozen water to pool up and possibly collapse inward into your house. If you discover that you have only a quarter inch per square foot, do not worry. This is a common mistake many homes have that can be resolved by installing a proper slope above the roof already in place. With the new proper rise, you will have nothing to fear.

Condensation Issues
Another important part of any metal roof is the vapor barrier system. This prevents condensation from pooling under the roof and leaking into your home to deteriorate the material beneath the sheet metal. In cases where the fiberglass has been overlapped or rolled and then stapled, the airtight seal necessary to avoid evaporated water from getting inside cannot properly function. This can not only lead to mold and rotten wood under your roof but also rust through the sheets. In severe cases, an individual may need to invest in sheet metal restoration to locate and correct afflicted areas and remedy the vapor barrier issue.

Snow Load
While many roofing companies will quote you an estimated safe loading pressure, some can make mistakes leading to overestimated numbers that leave you ill-prepared for the winter, especially in areas of high snowfall. Improper installation or using incorrect materials can both cause a professional to miscalculate the load bearing capability. This can also double with the incorrect slope to allow ice-damming which pools water to add to the weight already present due to snow on top of your roof. This could again lead to a need for sheet metal restoration once the inevitable collapse occurs.

In the end, only an expert roofing contractor can tell you if you have any need to worry about your home. Hiring a professional will let you know if your roof is pitched to the correct slope for your area and check to see that your vapor barrier is properly installed. Should you notice any of these three signs, contact a contractor today. Avoiding these common issues is sure to guarantee a long lifetime for your metal roof and for your home throughout many winters. You can learn more by visiting Heather & Little Limited.

What’s New at DeWalt Tools

DeWalt has been making some incredible tools for over 90 years. Beginning as a small company formed by the inventor of the radial arm saw, Raymond ReWalt, DeWalt tools have become one of the best brands in the power tool industry.

DeWalt has manufactured corded and cordless power tools for decades. This year, DeWalt has created some very unique tools that offer much more versatility than traditional power tools of the past. DeWalt’s stance is to provide the power of a corded tool with the portability of a cordless machine.

120V MAX Miter Saw

One of the most interesting tools I found in DeWalt’s new lineup is their 120V Compound Miter Saw. Not only is it a fully-functional compound miter saw, it has the ability to be run corded or cordless. It ships with a 120V AC Adaptor, as well as two 60V batteries that are used simultaneously to achieve a cordless 120V potential. This is incredibly useful if you are working in a situation where you do not have sufficient supply of electricity, and the work you need to do requires a lot of power.

60V MAX Table Saw

The reason that 60V batteries are used in the DeWalt line is because there are many new smaller power tools that can also use them due to their larger capacity and power. 60V tools include a grinder, reciprocating saw, table saw, joist drill and circular saw.

The DeWalt 60V 8-1/4″ Table Saw is an excellent choice for contractors who do not need as much versatility as a compound miter saw, but still need a high-quality saw to make accurate cuts where there is little electricity available. It also has a safety feature where it will not accidentally restart if a battery is added when in the on position. It features rack and pinion adjustment on the fence, making adjustments fast and accurate. It also has on-board storage for most of your needs, such as the fence, wrenches, miter gauge and saw guard.

20V MAX Backwards Compatibility

These 60V batteries are also compatible with older 20V models, which makes their lineup very flexible. The new 20V models include a power drill, impact driver, band saw, circular saw, miter saw, jig saw, reciprocating saw, grease gun, framing nailer, rotary hammer and more.

I am very excited for DeWalt tools and their new lineup, especially with their high-powered cordless saws. When you need a lot of portability but the power of a corded tool, DeWalt makes a very capable, high-quality product.

Applications That Benefit From a Cabinet Cooler

One of the most pocket-friendly and efficient industrial coolers in the world happens to be the cabinet cooler. The fans of this industrial cabinet cooler are of an advanced caliber of ingenuity that has increased the efficiency of electronic systems significantly. It is an economic savior for many electronic applications. Unfortunately, not all applications can benefit from the vast advantages of this industrial cabinet cooler. This cooler is extremely dependent on the ambient conditions. It is not applicable in appliances that are:
1. located outdoors where temperature and humidity levels are higher than required cabinet
2. exposed to materials of a corrosive nature
3. exposed to dust and other airborne impurities
4. exposed to liquid flowing
In the event such conditions cannot be averted, the use of a closed-loop coolant is mandatory despite the higher costs. Some of the applications that meet the standards of the industrial cabinet cooler include:
A. Programmable controllers
It is at times challenging to determine whether your wiring and junction boxes are certainly industrial control panels. Whether indoors or outdoors, they can be cooled with a cabinet cooler.
B. Relay panels
This application can provide more than 48 relays of control. These control schemes provide pocket-friendly but complex functions.They are often used in hospitals, airports and stadiums.
C. Food Service Equipment
Food preserving equipment like fridges and heating equipment like microwaves are some devices that heat up easily. They need efficient cooling for optimal functioning.
D. Audio-visual equipment
Equipment that is used in surveillance and entertainment generate heat often. Electronics like CCTV cameras, televisions and woofers must have this heat they generate spread out to protect them from malfunction. The electrical components have to be safeguarded for longevity.
E. Computer cabinets
Computers have to be the most ingenious devices yet to exist. They do a lot for the literary world. They also provide entertainment. These computers, especially, desktops, can get very hot. To increase the efficiency of your device, you can try to open up the enclosure. In place of the computer, cabinet, install a cabinet cooler with its fans inside.
F. Power distribution and switch gears
These applications are also susceptible to heating malfunction. The fuses in switch gears and power distribution have to be cooled. Portable substations are convenient for trade shows and manufacturing plants.
G. Lighting contactors

Introduction to Flexographic Printing Plate Sleeves and the Importance of Proper Maintenance

Flexography is a form of printing that applies the use of flexible rubber plates and first drying ink to print on a variety of materials. Flexographic printing sleeves are increasingly becoming popular because:
• It reduces damage on plates by excluding the need to remove plates between tasks
• Similar jobs can be mounted and stored to use later
• Flexographic sleeves are light in weight, long-lasting and easy to handle
• Flexographic sleeves work well with numerous materials, from tissue and paper towels to solid metal
Flexographic printing plates yield more opportunities in markets previously dominated by folding and shrink sleeves. However, to optimize the resourcefulness of plate sleeves, the equipment must be well maintained. Proper maintenance practices require diligence with observance of a set of rules. Some of the necessary maintenance protocols and their importance are highlighted below.

1. Clean plates
Proper maintenance and plate care will lead to cost-saving in the long run. This is because proper care will reduce the need to manufacture newer plates and provide better registration during printing. The most basic rule is, therefore, always clean the plates after removal from the cylinder. Furthermore, it is vital that the plate is clean while it is put onto the printing machine. If a dirty plate is used, particles may get stuck under the ink. Ensuring that previous residue and ink is removed will assure good ink transfer.

2. Proper storage
Plates ought to be stored properly after cleaning. Poorly stored plates are more likely to break down while not in use. Although automated cleaners work well, some cleansers used with them do not dry up quickly, such as oil. Leaving plates wet while storing them can result into the plates retaining the solvents. If plates are not stored properly to allow them to dry, the oil provides a moisture barrier. The moisture barrier will dissolve the plates. This will lead to a decrease in plate caliber. Before storing plates, it is essential to ensure that the plates are clean and dry to avoid further corrosion. Moreover, during storage, it is vital that the plates are away from direct light, high temperature, ozone, air, and electricity.

3. Proper cleaning
It is critical to use the right material while cleaning the plates. It is best to use horsehair brush or other soft material like sponges. Different cleaning materials can have different effects on the reliability of the plate. Use of the right cleaning agent, alcohol, is equally important in ensuring the plates lasts longer. Proper cleaning is important in ensuring the equipment operates at its full potential.

Flex storage solutions promote proper flexo printing equipment functionality. Under proper maintenance, equipment such as flexcart and flexstand last longer. Additionally, digital imaging of plates through the use of Flexstand operator has brought about numerous developments to flexographic printing as compared to traditional methods.
