Window


THE CODE

The code basically breaks down the method to meet the higher window load requirements in two ways:  the window itself, and its installation.  It says that the window must be able to withstand the “large missile impact” of a 9 pound 2×4 hitting the window at a speed of 34 miles per hour without penetrating the opening. The glass may break, but the opening must not be penetrated. Then, the windows and doors also have to withstand 9,000 cycles of positive and negative air pressure, such that a real hurricane could pull a regular windows right out of its frame.

THE WINDOW

To meet the penetration restriction, window manufacturer’s all use a similar type of impact window glass that’s much like a heavy duty car window.  Florida’s Best Windows and Doors manufacturing process is basically the same as it is with most window manufacturer’s:  their design consists of a clear plastic interlayer sandwiched between two panes of glass.  Two types of interlayer are used:  Polyvinyl butyral (PVB) and SentryGlas Plus (SGP).  The SGP is more rigid and less likely to tear than PVB.  For that reason, some manufacturers use it in their larger windows, or those windows designed for the highest wind zones.

The glazing system is also an important factor: a silicone sealant that may be strong enough to hold the glass in place in a Zone 3 impact test, but would likely fail in a Zone 4 test, causing the window to fly out of its frame.  Windows in the higher test category would instead use something more like a construction adhesive for its glazing system. “The difference, says Kurt Mendez of Florida’s Best, is between Elmer’s glue and super glue.”

Window manufacturers also reinforce the frames in order to meet requirements.  Lawson Industries uses a one piece sill plate (this also helps to prevent water leaks into the home) and interlocking meeting rails which ties the sash together when shut.  Heavier locks also place a role in meeting impact tests, as they can be critical on certain types of windows, such as casements.  For a casement window, the only thing holding the window sash in place under negative pressure is the hinge on one side and the lock on the other.

Today, virtually all of the major window manufacturers make a high-grade, impact-resistant window that has been certified to meet protective standards. The current gold standard in testing is the Miami-Dade County hurricane impact test (http://www.miamidade.gov/buildingcode/online_product_search.asp).  Remember, it is your life and your property. Essentially all of Florida, and all the coastal regions of the United States should prepare for possible wind speeds of 110 mph or greater.

INSTALLATION

For the window to withstand hurricane conditions, something similar to the 9,000 cycles of positive and negative air pressure they undergo in impact testing, the installation is every bit as important as the quality of the window.  Dave Olmstead, spokesman for PGT Industries in Venice, Florida, agrees that no matter how strong a window is the attachment to the building structure is critical. Olmstead says a window that is 53-inches by 76-inches would have 28 square feet of exposure, and with a wind speed of 146 mph from a category 4 hurricane would result in a load on the window equivalent to 1,958 pounds of pressure. For the window to perform correctly, the load has to be transferred to the building itself, which is done by using suitable anchors to transfer the load from the window or door frame to the rough opening without causing failure.  Therefore, the installer needs to be knowledgeable in how to use this system and its different anchoring mechanisms.

Through the construction side of our business, we have had to make major repairs to structures as a result of poor window installations by other contractors – everything from using the wrong sealant to the extreme of installing regular windows instead of the hurricane impact windows the customer paid for.  Something as small as the using the wrong sealant can cause significant damage to a home – rotting framing members, structural damage, mold, etc.  Since leaks are often inside the walls long before a homeowner notices them inside the house, they are often not detected until there is major damage and then expensive repairs have to be made.  This experience is invaluable for our installers.  In addition to the installation training we give them, they get to experience firsthand the things that can go wrong with window and door installations and how to prevent them in the work that they do.

EXTRA BENEFITS
Benefits from impact-resistant windows extend beyond the storm belt to broader security and environmental concerns. Impact-resistant windows are considered to be security features because they are so difficult to penetrate or separate from their frames that they reduce break-ins, theft, and property damage. On top of physical and financial protection, impact-resistant windows also can preserve mental health. Who hasn’t been disturbed by car alarms, barking dogs or noisy neighbors?

“They do a good job of keeping outside noise outside,” Olmstead says. “With almost every homeowner, that’s the first thing they notice: How quiet the home [became]. Noise abatement is far more important than people realize.”

There are insurance breaks for new homes built with impact resistant windows, and for existing homes remodeled to include the tougher windows and frames. This discount can be as much as 50%.  Check with your homeowner’s insurance carrier to see what kind of a discount is available.

Replacement windows for your home can be significant investment in both time and money.  There are many manufacturers, window types and styles, and a wide price range from which to choose, and the decisions you must make can seem endless. Which manufacturer should you go with? Do you want aluminum windows or vinyl windows?  Should you choose hurricane impact resistant windows or non-impact windows with hurricane shutters?  What about double pane-thermal insulated or thermal insulated with hurricane impact resistant glass?  How can you take advantage of the new Energy tax credit of up to $1,500.00?  Of course, as you make these choices you’re reminded that buying windows is like buying anything else: the more items we put in our ‘cart’, the higher the price.  Choosing the right windows and a reputable company to install them for you can take a lot of time and homework, so here is some helpful information to get you well on your way.

Choose a Window

Before you decide on a manufacturer, it’s important to find the right window that fits your needs and wants. Not all manufacturers make all types of windows, so choosing a window first prevents you from being limited to the windows in any given manufacturers’ line.

When deciding on the perfect windows, take a little time to decide which features you need for your situation and which benefits you want to include in your new window purchase. A must for many homes here in Florida is hurricane impact windows.  As opposed to single-pane windows with hurricane shutters (or boarded up with plywood), hurricane windows are always ready to protect against high winds whether you’re home to put up the shutters or not. Impact windows not only provide much needed protection during a storm; they can also be very energy efficient — some of our brands can save you as much as one month of electricity.  Another benefit is security against home burglary, a rapidly increasing crime in these economic times. The same shatter-resistant construction that protects against hurricanes also prevents thieves from breaking into your home through your doors and windows, giving you total piece of mind.

Another important consideration in choosing windows is that building codes in many areas of Florida now require impact resistant openings for your doors and windows.  Furthermore, it is the shared opinion by many in my industry that with the way the insurance industry is headed in Florida, homeowner insurance will become very difficult or prohibitively expensive to obtain without having the window and door openings of your property “hardened” (i.e., installing impact resistant products).  Hurricane windows are definitely worth the investment, and once you decide they are the right way to go, it’s time to make more decisions.

Choosing Frames

In Florida, some other considerations are whether to choose an aluminum frame window or vinyl.  The majority of hurricane impact resistant windows are aluminum.  It is stronger and therefore easier to build the window to the standards needed to obtain Miami-Dade product approval for the impact window rating.  There are very nice vinyl impact windows on the market that do meet code requirements, however expect to pay a premium for them.  The difference between aluminum frame and vinyl windows (besides the price) is that vinyl conducts far less heat than aluminum, making vinyl much more energy efficient.

When considering frame construction, keep in mind that welded frame windows are usually stronger than comparable units which are screwed together; this is especially important for vinyl windows. The welded frames help to hold the unit flat and square during the installation process and makes installing them much easier.  Welded vinyl frames can also offer a virtually air tight frame construction which again can benefit the insulating properties of each replacement unit. A comparable welded frame will usually cost more than mechanically fastened units but the extra expense will pay off when your sashes work freely and properly without unnecessary friction. There’s nothing worse than sticky and poorly operating sashes.

Determine ahead of time which colors will match your home’s interior and exterior the best. Decide if you want just simple white windows, or brown or tan cladding. Do you need a tint or heat-reflecting Low-E glass?  Do you live close to the ocean and need special turtle glass?  These are all important considerations. You must also decide how you want the window to operate and function.  Do you want single-hung, double-hung, horizontal sliding windows or maybe casement?  Some of your decision will be based on architectural appeal, some of it price, and some of it operational.  For example, when choosing impact windows I prefer horizontal sliders over single hung simply because the impact glass is heavy and sliding them open and closed is just easier, and I think they have a very nice look.

Installation

While windows can be installed by the homeowner, unless the homeowner is a qualified contractor with window experience, it’s never a wise idea. Hiring the budget handyman to install your new windows can be an even bigger mistake. Even the very best quality window will not work properly if it is not shimmed, level, plumbed, attached and installed properly. Improper installation is often not readily apparent but if there is a slight flaw in the installation, the windows in which you invested so much time and money will eventually fail to operate properly. It may be a year or two or three, well after the installer is gone — and so is your warranty.  Finding a qualified company to install your windows is well worth taking some time and doing a little research, before you buy your windows. It is much easier to avoid future problems before you start rather than trying to fix them after they have already occurred. As a licensed contractor, I have seen the result of many botched installations and do-it-yourself situations gone awry. In the end, you’ll be happy that you made an educated decision on your window purchase and will feel confident that they were installed properly by an experienced and qualified company.

It may sound like a lot of information and choices, but if you can get a reputable window company to help you, all these decisions get much easier.  A reputable window company can guide you through all of your options fairly quickly while answering your questions and concerns.

Double Glazed Sash Windows

Whether you’re a UK landowner that is contemplating the installation of double glazed sash windows, casement windows, bay windows or maybe another favored window selection, look at the statutes which encompass window replacements. Windows must conform to a set of rules called FENSA. Here’s some information about these rules.This is info concerning these provisions.Here is a bit of data pertaining to those regulations.These are a number of facts about the laws

UK Sash Windows : What Does FENSA Do?

FENSA means Fenestration Self-Assessment Scheme. Authored by the Glass and Glazing Federation (GGF), under the government’s watchful eye, FENSA can be seen as a positive response to building codes in both England and Wales. FENSA is merely a collection of work values concerning replacement sash windows and other types of replacement windows. The FENSA laws help the businesses who merchandize and install he windows, the customers who attain them, and the local governments who make the building laws. FENSA makes sure that all window improvements or remodeling which a property owner takes on will comply with essential structural principles.

Sash Windows : Data Related to FENSA

Higher than 9000 industries registered with FENSA have worked with higher than 6000,000 houses inside Great Britain. More than twenty-four percent of homes in England and Wales have implemented FENSA- certified suppliers and installers. Having been around since 2002, the most recent version of the FENSA regulations is calculated to facilitate in the safeguard of the environment as well. Case in point, because the power that is utilized to cool, heat, and light up buildings inside the UK is to blame for half of the carbon dioxide emissions in this country, the FENSA regulations are composed to lessen these and more dangerous emissions which could be harmful to the earth’s ozone layer.

So, regardless of whether you’re looking for, double glazed sash windows, wood windows, vinyl windows or aluminum windows, selecting a FENSA-certified UK contractor to put them in lets you know that the job is done correctly, is finished as scheduled, and also within the budget.

Being that you are a UK homeowner with property owner who has sash windows, after a while, more than likely, they will need traded. These are facts to help you make up your mind about new sash windows.

Sash Windows UK: The Purpose of Interchanging Your Sash Windows

An essential objective for those who opt for attaining replacement windows rather than simply repairing their existing window sashes is because lots of times replacement sash windows are more cost effective than time-consuming repairs. Over time wooden sash windows will become unstable and start to disconnect. Also, the glazing putty can fall out due to dryness. One more reasonable intention for replacing sash windows is because there’s a possibility that lead paint was used to coat them. In addition, replacement windows have superior insulating properties and are easy to operate. Also, replacement sash windows diminish draftee situations and get rid of high heating bills because they almost always are double paned. In other words, there is a couple of glass panes inside of the casing which are parted by a space. This space is full of air or advanced tech argon gas, which heightens the insulation matter.

Sash Windows: The Solution is to Get a Knowledgeable Contractor

Despite the fact that you chose timber sash windows or UPVC sash windows, be positive that you attain approximations from numerous contractors. A reliable contractor should study your window problem and could inform you of options including fixing up the woodwork on as low as one or as much as all of them. If you want, the contractor takes out whatever amount of windows you want and customizes new ones. On the contrary, in a case where the woodwork is rotten, or the frame drips, the contractor can advise you to have the complete framework replaced – plus the window itself. Every bit of this information should be provided along with the estimation that the contractor gives you.
