Factory-Direct Manufacturing Concept
Selling windows and doors that the company manufactures itself, so that customers buy from the manufacturer rather than passing through several distributors.
We make our own products here on Long Island. Unlike most companies that sell and install windows and doors that they buy from many different manufacturers, we primarily sell what we make ourselves. We only make one series of windows and doors and focus only on the best quality products.
Why Us - Royal Windows And Doors - published by Royal Windows and Doors
Whether you are an architect, a builder, a contractor or a homeowner we can provide great quality Windows and Doors at competitive prices. Our competitive advantage is the fact that our clients come directly to us, the manufacturer and avoid having to go through several distributors.
Royal Windows and Doors - published by Royal Windows and Doors
By coming directly to the manufacturer you get access to our knowledge base that we have accumulated over the last 35 years of operation and can get excellent quality products at attractive prices.
Why Us - Royal Windows And Doors - published by Royal Windows and Doors
Single Product Series ProprietaryTerm
Royal Windows and Doors' practice of manufacturing only one series of windows and doors, at the top quality level, instead of several series or grades of the same product at different price points.
We manufacture only one series of products and only the top quality that can be found in the market. This makes it simpler for our customers to choose with confidence. The only disadvantage to us is that we do not offer products that may be in the desirable price range for all projects, for example commodity builders or flippers.
Royal Windows and Doors - published by Royal Windows and Doors
This is also the same reason why we do not have several different series or grades of the same product reflecting differences in quality and price.

Insulated Glass Seal Failure Concept
The eventual loss of the hermetic seal on an insulated glass unit, which lets moisture and then dirt into the space between the glass panes.
Over the passage of enough time every insulated glass unit currently available for use in windows and doors will lose its hermetic seal, and moisture along with dirt will get inside the space between the glass panes. It is not a matter of whether an insulated glass unit will fail, but rather how soon after it is made the failure will happen.
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
The first sign of a failed glass unit is the appearance of moisture in between the insulated glass panes. You would know it is inside the glass space because you cannot wipe it clean from either surface of the insulated glass unit.
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
If the window framing material is in good shape and the window functions properly when opening and closing and it has not become drafty because it has started to deteriorate, then replacing the glass only is a good option. If the window itself has gotten compromised, then replacing the entire window may be a better option.
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
Air Infiltration Concept
Air leakage through a window or door assembly, which varies by window type and design and is measured under conditions specified by ASTM.
All operable windows allow at least some air to go through them either from outside into the house or from inside the house to the outside. The amount of air leakage however varies a lot based on both the type of window in consideration as well as the design and ultimate quality of the window as it relates to how efficiently it can prevent air leakage between the window frame and the operable sashes. Most manufacturers test their windows for air infiltration under conditions specified by the American Society for Testing and Materials (ASTM).
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
Casement windows that rely on gaskets, rather than weatherstrips, to seal the sash to the frame, are in general more efficient than double hung and slider windows when you compare their air infiltration performance.
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
In many cases windows that feel to be drafty allow air to come through around the perimeter of the window where it connects to the wall. This is always the result of poor installation where the installer did not properly insulate and seal the space around the window to the wall opening.
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
Flanged vs Non-Flanged Window Installation Concept
The choice between installing a replacement window with a flange around the exterior perimeter of the frame or without one, determined by the condition of the exterior wall and the window being removed.
There are two main ways to install new windows into an opening. The first is to use windows that have a flange around the exterior perimeter of the window frame, and the second, to use windows without a flange. The best rule of thumb to help you decide if the new windows need a flange involves the evaluation of the exterior wall where the windows will be installed.
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
If the exterior walls are covered with any type of siding and there is no old wood window frame that will remain in the wall, then the windows need to have a flange to be installed properly and avoid water penetration into the walls.
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
This is extremely important because the wrong installation will not only compromise the function and efficiency of the windows, but it could compromise the integrity of the structure of the house by enabling water to go around the window frames and reach the walls, resulting in rotted walls and the promotion of the growth of mold inside the walls.
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
Door Frame Rot Concept
The softening and rotting of the wood frames most doors are hung on, caused by exposure to moisture and by frames that have not been properly painted.
Most doors are hung on wood frames. These include wood doors, fiberglass doors or steel doors. Depending on the exposure of the frames to moisture and how well the frames are maintained, to make sure they are properly painted to prevent them from absorbing moisture, at some point they will start to become soft and rot out.
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
The problem of rotted door frames is mostly found in doors that are completely exposed to the elements especially rain. Doors without any overhung whatsoever are the most vulnerable to having their frames rot out starting at the bottom.
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
In addition, if you plan to attempt a repair like this it would be advisable to source a section for the door frame you will add that is synthetic and not wood, to prevent the same problem form happening again in the future.

Six-Decision Entry Door Selection Methodology
Royal Windows and Doors' method for specifying a new front entry door through six decisions: layout, material, amount and shape of glass, type of glass, color, and lockset.
Relations:
The available door styles and configurations that you can select from can be in the hundreds when you consider all the available variations in the marketplace. There are however only six major things you can specify to arrive at the final choice.
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
The very first decision that needs to be made is what we call the layout or arrangement of your new door. In other words, are you looking to get a single door, door with side panels or double door, as well as the consideration of transoms, or windows over the door.
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
The sixth and final decision for you to make is the lockset for your door. Ideally you want to choose something that works and enhances the look of everything that you have chosen so far.
FAQ - Royal Windows And Doors - published by Royal Windows and Doors
Not all door manufacturers will give you this much flexibility to put together a door for your house. Most of them will present you with a catalog that has a fixed number of choices, and you can only pick what is shown in the catalog.
