A Layman’s Information to Joinery Specifics and Figures


I myself am fairly new to the joinery producing business enterprise and its been a steep finding out curve. The people today I function with know their trade and babble absent in “joinery” converse though I sit there making an attempt to comprehend it all.

The to start with and most likely most unconventional thought to appear to conditions with is the use of imperial and metric- generally in the identical sentence! For instance- ” I have to have 3 items of PSE softwood, 22mm x 10mm, 4 No @ 6′ “.

This to the average individual is almost nothing brief of another language. To explain- PSE is PLANED Sq. EDGE timber. Purchasing timber this way signifies that you have a square edge to measure from but it is far more high priced. Most of the timber bought by production organizations is tough sawn, IE straight from the timber merchants and slice a minimal oversize, generally with some bark however attached and the standard problems.When purchasing timber, a specified total of squander is taken as regular. Slicing the finishes to square up the timber is the initially stage. Then several passes by a 4 sided planer which decreases the thickness of the timber nearer to the needed size and gets rid of the bark. The edges could will need running in excess of a planer/thicknesser to square them up far too.

In joinery – it is generally fantastic exercise to give the width measurement initially,so in the previously mentioned case in point-22mm large and 10mm deep. This is especially vital if the 2 measurements are extremely near, acquiring it mistaken signifies that whichever you are creating will not healthy properly. Measure two times lower as soon as!

4 No is of system how a lot of you want- reasonably self explanatory.

Then 6′ in length! We just cannot get absent from using imperial. Just imagine- if anyone asks how tall you are- the normal reply is 5′ 3″ or 6′ 2″. We will not say- I’m 1580 tall or 1860. Men and women just know what you suggest.

Its the exact in joinery- 5mm, 15mm, 1 metre, 50 percent inch, 2 foot- it all will get utilised. Generally- most firms will work with possibly metric or imperial- so will not be anxious. Metric is a lot more precise- applying millimetres usually means fewer prospect for faults.

When we order hardwood it is calculated in cubic ft and when buying softwood we obtain in cubic metres, which all adds to the pleasurable and games!


There are quite a few various styles of window and fashion- we shall focus on 3. The standard window, stormproof and sliding sash.

The first two are rather equivalent in lots of ways- the principal exception is the sash’s. The sash is the opening or non opening further body surrounded by the outer frame. On conventional home windows there is typically a sash even when it is non opening and this gives an general harmony to the window appear. The opening sash lies flush with the frame. On a stormproof window- frequently observed on far more present day residences or in parts of harsh weather- the sash body wraps all around the primary body, overlapping it to give further defense.Each styles of window will have hinges of some description making it possible for the sash to open.

The sliding sash is observed on lots of historic and detailed structures, and normally has two sash’s which can slide up and down depending on requirement. Is does not have hinges, but is effective on weights and cords to lift and drop the heavy sash’s. Contemporary sliding sash home windows utilise a spring as a substitute of the weights generating for simpler use and lowered body size. There are also “Mock” sash windows which seem like normal sliders but perform on a friction hinge- see my post on sliding sash home windows for extra details.

The frame is the outer timbers comprising 2 facet pieces called jambs and a prime piece referred to as the head and the base section known as the cill or sill. The sash itself is created up of 2 vertical stiles and 2 horizontal rails. Muntins are the title specified to both horizontal and vertical dividing bars which split the window glass into personal panes or lights.

Most fantastic joinery businesses will be content to present you their function and discuss your prerequisites. Just bear in mind when choosing- not all home windows are the similar- verify out the timber, the body section dimensions and the finish.


All doors are not made equally either- quite a few exterior doors are neither stable or very well made. Conventional thickness is all around 44mm, so be absolutely sure to look at out what you are obtaining for your cash.

The fundamental door design is a frame – comprising 2 facet stiles and a best and bottom rail. There are several variations to the actual make up of the doorway- but transoms are the horizontal timbers and mullions are the vertical timbers. Infills can be stable panels- this kind of as elevated and fielded- which are very common and give a central flat panel with sloping edges, or potentially glazed units in a big quantity of variants, like leaded glass, obscure and super efficient double glazing. Glass for doors ought to be possibly toughened or laminated to conform to constructing polices- don’t settle for just about anything significantly less.

Also examine that mortice and tenon joints are employed in the development, as many organizations attempt to conserve funds but utilizing inferior jointing procedures. A effectively manufactured mortice and tenon joint, glued up will be more powerful than the bordering timber and should hardly ever occur apart.

The timber is also crucial- TEC wooden is a laminated timber ( which usually means it has layers glued jointly for toughness and security) which is remaining made use of extensively. Timber option in the Uk must be a hardwood this kind of as Sapele or European Oak. Idigbo and Iroko are also good selections. Ask your joinery corporation for their suggestions on whats very best in which circumstance. Budget will also perform its component, but there are often selections.

A rebate is a groove slash in possibly the edge of the timber- EG where doors shut jointly or can be a lower in a flat panel to take yet another panel.
