What is Overlap Rabbeting?

Overlap rabbeting on exterior shutters is a groove along the vertical edge that allows one shutter to overlap the shutter next to it.  An overlap rabbet is very much the same as what is termed as a shiplap joint or half lap joint.

 

Overlap rabbeting can be found on all functional exterior shutters and for a very good reason. With an overlap rabbet the shutters will close over one another eliminating any exposure in the center leaking rain, light or air . The overlap rabbet also creates a solidness to a closed pair of shutters locking them tighter together to eliminate any "shuddering" for better storm protection.

 

 

 

Is Overlap Rabbeting just for Exterior Shutters?

An overlap rabbet is just as important for interior shutters.  With an overlap rabbet UV rays are blocked from damaging your room furnishings   as well as providing a tighter seal over the window giving better energy efficiency.  If you are using your interior shutters as blackout shutters for a bedroom or a media room overlap rabbeting is a must. 

Overlap rabbeting is decorative, as well as functional, giving a neater and more finished appearance.  If you look at the picture to the right you will see the half-round bead detail.  This is shaped into the wood shutters to give a more uniform look to the face of the shutters.  This type of rabbet is referred to as a beaded overlap rabbet.

When should I use shutters with overlap rabbeting?

A good rule of thumb, for both interior and exterior shutters, is to have an overlap rabbet if your shutters are meant to be functional or at least look functional.  It is an option that adds very little to the cost but greatly increases their value.

I think what I like most about this time of year isn't just one thing but a whole list including the many decorations on homes and stores, holiday meals and desserts like Gingerbread Cookies and the many fresh smells including the outdoor freshness of pine and balsam.  I also enjoy the feeling of contentment that everyone including myself seem to find once Christmas Eve arrives and hearing the many songs and stories including this old classic below which was written at a time when window shutters were a common necessity to keep out the cold:

 

A Visit from St. Nicholas

 

'Twas the night before Christmas, when all through the house

Not a creature was stirring, not even a mouse;

The stockings were hung by the chimney with care,

In hopes that St. Nicholas soon would be there;

The children were nestled all snug in their beds,

While visions of sugar-plums danced in their heads;

And mamma in her 'kerchief, and I in my cap,

Had just settled down for a long winter's nap-

 

When out on the lawn there arose such a clatter,

I sprang from the bed to see what was the matter.

Away to the window I flew like a flash,

Tore open the shutters and threw up the sash.

The moon on the breast of the new-fallen snow

Gave the lustre of mid-day to objects below,

When, what to my wondering eyes should appear,

But a miniature sleigh, and eight tiny reindeer,

With a little old driver, so lively and quick,

I knew in a moment it must be St. Nick.

More rapid than eagles his coursers they came,

And he whistled, and shouted, and called them by name;

"Now, Dasher! now, Dancer! now, Prancer and Vixen!

On, Comet! on Cupid! on, Donder and Blitzen!

To the top of the porch! to the top of the wall!

Now dash away! dash away! dash away all!"

As dry leaves that before the wild hurricane fly,

When they meet with an obstacle, mount to the sky,

So up to the house-top the coursers they flew,

With the sleigh full of toys, and St. Nicholas too.

And then, in a twinkling, I heard on the roof

The prancing and pawing of each little hoof.

As I drew in my hand, and was turning around,

Down the chimney St. Nicholas came with a bound.

He was dressed all in fur, from his head to his foot,

And his clothes were all tarnished with ashes and soot;

A bundle of toys he had flung on his back,

And he looked like a peddler just opening his pack.

His eyes -- how they twinkled! his dimples how merry!

His cheeks were like roses, his nose like a cherry!

His droll little mouth was drawn up like a bow,

And the beard of his chin was as white as the snow.

 

The stump of a pipe he held tight in his teeth,

And the smoke it encircled his head like a wreath;

He had a broad face and a little round belly,

That shook, when he laughed like a bowlful of jelly.

He was chubby and plump, a right jolly old elf,

And I laughed when I saw him, in spite of myself;

A wink of his eye and a twist of his head,

Soon gave me to know I had nothing to dread;

He spoke not a word, but went straight to his work,

And filled all the stockings; then turned with a jerk,

And laying his finger aside of his nose,

And giving a nod, up the chimney he rose;

He sprang to his sleigh, to his team gave a whistle,

And away they all flew like the down of a thistle.

But I heard him exclaim, ere he drove out of sight,

"Happy Christmas to all, and to all a good-night."

 

Finding a wood shutter supplier with a simple Google search is easy, just be attuned to where and how the shutters are made and with what they made with before you buy. Do your homework by simply asking questions and doing some internet research on the materials and construction methods. There are many types of wood that shutters can be made with but you’ll want to choose the material that is best suited for your installation whether it is inside or out.

Each supplier or direct manufacture should be able to help you with selecting shutter and shutter hardware styles suited for the application and the sizes that you will need. Some companies even offer finishing services from a basic prime to a full finish ready to install. With the different types and styles of shutter hardware that are available your shutters can be fully functional as well as decorative.

Here at Kestrel Shutters & Doors we have been making both interior and exterior shutters since 1989. We are located in Southeastern Pennsylvania where so many shutters adorn the classic Chester County façade found on many historic homes and sites. The shutter designs that we have chosen as ‘standards’ follow the older shutter styles found not just here in Chester County but also throughout the US and abroad.

The shutters that we build are made entirely by us entirely here in house. We have a very good as well as dedicated team who produce each order. It’s a several step process before each shutter is assembled by hand. The process begins with hand sorting rough lumber for each order and then milling it to size and profile. Through the use of various specialized equipment we then process the milled materials into individual component parts. Where components are joined together we use what is called a mortise and tenon joint construction.

Note: Just because it's mortise and tenon joinery does not imply that it is good unless it's milled correctly. Joints that are loose or secured with screws in the end of the tenon are not as strong and are prone to failure. The best and most historically accurate way to secure a mortise and tenon joint is with a peg that goes through the tenon locking it in place like a cotter pin.

Kestrel mortise and tenon joints fit snugly together and are secured with Honduran Mahogany pegs. The pegs are positioned on the face of each stile according to the size of the tenon.

The hardwood that we use, Basswood and Spanish Cedar, come out of forests that are managed and are harvested responsibly. American Basswood is for interior use and Spanish Cedar is for exterior and interior use. Basswood, known as Linden wood, is used by woodcarvers because of it's many good qualities. The stability, workability, and light patterned even graining is why carvers use it and that is what makes it a great choice in making interior shutters and interior doors, especially those with louvers, since the material holds straight and true. Spanish Cedar is traditionally used in lining cigar boxes and humidors. We began using Spanish Cedar over a decade ago as an alternative to Western Red Cedar because of the consistent quality of the wood that was lacking in Western Red and we found it to be more durable. While Spanish Cedar is predominately used for exterior work because it "breathes" out moisture making it rot resistant, the material also performs very well for interiors too, especially in humid areas where moisture is prevalent. It has also been used as a substitute for Honduran Mahogany since the grain pattern, color and quality are very similar.

Every shutter and door is made to order and available in unfinished wood or completely finished. By choosing full finishing in either paint or stain the shutters are ready for installation once received. However, if you are a DIY, do-it-yourself, kind of person we are the originator of a product called The Original DIY Shutter™ kit.

DIY Shutters™ are the same as our fully assembled version; we just do not assemble them. DIY Shutters™ are an easy to assemble kit to be completed start to finish on site with some general woodworking tools. We developed DIY Shutters just about the same time that the company started. The benefits in a DIY kit is about saving money and a great satisfaction in building your very own top quality shutters.

Did you know? We also offer DIY Shutter™ component parts.

Deciding on a Louver style is a combination of how the louvers will be used, the surrounding décor, and your own personal preference.

First to think about is how will the louvers be used. For both inside and outside applications knowing the purpose of the louvers is helpful to determine if you need fixed or operable louver blades- then you can decide on louver width. Some things to consider when choosing a width are if the louvers are going to be used for privacy, ventilation, and if you will be adjusting them for viewing. If you prefer to have operable louvers, both narrow and wide louver widths will provide privacy when closed. However, a larger louver blade width will have a wider viewing area since each louver is spaced further apart. Also, a wider operable louver blade will allow for greater ventilation since blades can be adjusted to a fully opened position. The opposite is true with our standard fixed louvers. In a smaller stationary louver greater ventilation is achieved because there are more open areas simply because there are more louvers.  When louvers are used to hide appliances make sure that you have the required amount of cubic feet per minute, CFM, of air flow.  Keep in mind that fixed louvers do not offer complete privacy but if you like the look of louvers and do not have ventilation requirements you could choose a faux louver which will provide privacy with a louvered look.

The next consideration is the surrounding décor. Your home may be anything from Traditional to Contemporary, Cottage to Art Deco but, regardless of styling, any of these could match a narrow louver blade or a wide louver depending on room, window, and furniture proportions. Match the louver size with the scale of what you see. In my last post, “Made to fit vs. Make it fit”, I mentioned proportions and how some are more comfortable then others. For example, a large window with one shutter might not suit smaller louvers but be perfect with wider louvers for a more open and airy appearance. The same window when fitted with several smaller shutters will look proportioned correctly with a smaller louver.

Sample louvers can help you see which looks best for the application if you are just not sure. Much like taping paint color samples onto a wall when deciding on room colors and glancing at them at different times of the day to see which one you like; do the same with louver samples, you’ll know in a matter of days which one is just right for you and your home.

Did you know? Plantation Louvers may give a hint of a Southern style but it is actually just a generic marketing name that refers to an operable louver shutter with a louver blade that is between two to three inches in width. However, you will find that louver blade widths can be dependant throughout regions due to both climate and cultural differences.

Note: If you live in an old historic home then you also need to consider what the home should have. If you are lucky you will have some of the original shutters but if not check other old homes of a similar style nearby that might have their original shutters. Most likely yours had very much the same. The historic commission in your area should also be able to lend some assistance with old photographs.

Louver & Panel combination shutters:

Don’t judge a book by its cover. We have all heard this numerous times in our life and yet we still let ourselves be surprised when something is not as it seems. It is that mouth watering piece of moist, dark chocolate cake that, sadly enough, turns out to be some bizarre experiment in carob meets soy paste. Recently it was Aqua Dots, a cool looking toy and craft for small children that has since been recalled because it contains a variation of the date rape drug. Whoops!

Sometimes it is mass produced shutters, many made in China, that are finished with what we assume (and hope!) is a non toxic paint and sold on web sites and in American home centers. Granted they do look nice but then again, what wouldn’t? How many curb appeal type shows have we all seen where they stress putting on fresh coats of paint to hide poor workmanship just to make it easier to sell your home. Because it looks shiny and new doesn’t mean it was made well.

When buying shutters, whether they are for the interior or exterior of your home, spend some time “kicking the tires” so to speak.

Is the wood a solid hardwood or finger jointed drop off?
Is the joinery traditional pegged, mortise and tenon or do they cut corners by using dowels and screws?
Are the operable louver self balancing so they stay in any position you place them or do they rely on a mechanical tension screw that you need to adjust every time the humidity in your home changes?
Do the fixed louvers and panels float to allow for expansion and contraction?
Are the operable louvers attached with solid brass screw eyes that cannot fall out or do they use staples that will, sooner or later, fail?

Really, the idea is to try to learn as much as you can about your shutters before you buy them. Get samples from each company and compare. Does the shutter feel substantial in your hands or are you afraid that one good sneeze might tear it apart? Look behind that pretty white paint and golden oak stain and see for yourself whether your shutter is really a shutter, or is it just a lemon.
