Window options for Ron Currie windows

When ordering a window, there are many options to consider. Please read all of the below before ordering a window.

Internal window moulds

Below are illustrations of the different moulds which you can have on the inside of your window. There are three to choose from.

Ovalo & bevel

We use an Ovalo on the casement and a 9° bevel on the frame. This gives the window a traditional feel with a contemporary twist. This design is pictured in Softwood.

Full bevel

We use a 20° on the casement and a 9° on the frame. This gives the window a much more contemporary, smooth lined feel.

This design is pictured in Sapele.

Full ovalo

We use an Ovalo on both casement and frame. This is the most traditional window mould and is pictured here in Softwood.

See notes on this below table.

Full ovalo notes: Due to the amount of room this mould needs, you have 2 options. The first option is to use standard stays and fastener ironmongery where you will have to pay 10% extra on the overall cost of the windows due to the increases amount of timber required. The second option is to keep the same amount of standard timber section and use espag locking system with friction hinges. You will have to pay extra for this ironmongery (See 'Extras' down the page).

Listed buildings

We now have the facilities to match your grade II listed buildings windows as near as possible. This includes the thinner glazing bars typically found on them, and the scribe jointed corners expected on these types of windows. Please see towards the end of the guide for the moulds we can do, and details of the thinnest glazing bars possible with different moulds. We cannot always give a true 100% match, but we will get as close as possible. If you need this type of quote please enclose some photos along with the quote request form at the end of this guide.

The pictures below illustrate the different moulds that we can use on listed building windows.  The bevel facilitates the thinnest bars at 21mm. The router and ovalo moulds both require 30mm thick bars. This is only achievable on single glazed windows. Below are examples of each mould.

21mm chamfered bars

Pictured is a pine yorkshire sliding sash with scribe jointed 21mm chamfered glazing bars. These are the thinnest bars we can achieve. Beading is not possible in this construction; putty has to be used to hold the glass in.

30mm ovalo bars

Pictured is a window with scribe jointed 30mm ovalo glazing bars. On this window we have used a 9° bevel around the frame and an ovalo mould on the casement and glazing bars. Beading is possible with this construction.

Multipoint espag locking system

We now have the option of fitting your new windows with a more secure multipoint locking system. The advantages to this are as follows:-

The system can be fitted into any of our windows (with the exception of sliding sash). We highly recommend this system due to its security and its quality.

Pictured below is a window with the espag locking system fitted. The window is a traditional georgian window, in idigbo, with satin chrome ironmongery.

Internal view of the casement.

Open view of the casement.

The pictures on the right show the casement opening. On the open view you can see the receiving plates for the locking bolts and the Friction Hinge at the bottom of the casement.

The photos on the left show the multipoint locking system. This system shoots the hook bolt shown into a receiver housed into the frame. This is the locked postion. When the handle is lifted the bolts retract so they are flush with the edge of the casement and the window will open. We can also install a night vent facility, at no extra cost, so the window can be locked, but still allowing an airflow. This does not replace the need for trickle vents when vents are required.

The cost to install this system is £40 per casement (opening part). For this you will get the Locking system installed, the casement will be hung on friction hinges as opposed to standard hinges and the locking handle will be included (any of the below finishes) .

The handle left is what we supply as standard with the espag system. Its available in the following finishes: Brass, Chrome, Satin Chrome, Black, Bright Bronze, Satin Bronze and White. We can supply handles in Antique Black (£10 extra) and Pewter (£15 Extra) see pictures below in the ironmongery selection section for style.

Finishing service

We now have the option of having your windows primed, base coat stained, painted to a finish or stained to a finish. We use the acclaimed Sikkens Joinery Coatings system applied by spraying. We can finish in paint or stain. Below are a couple of example windows. The stained one uses Teak Stain, the painted one is in British standard white. Please ask for a price if you require this service.

Fire escape windows: Always make sure you identify whether or not you require your windows to have a fire escape. This has caught many people out. If a window hasn't been made to a fire escape specification, the window will usually have to be scraped and a new one made. At present the regulations state that a fire escape window needs to have a clear opening of at least 450mm and have an area of at least 0.66 square metres. You must always clarify this with you local council building control. See our flying mullion fire escape.

Traditional casement construction

As you can see below the 'idigbo' casements finish flush with the outside of the window. The casements are hinged on butt hinges. There is a more work involved in producing traditional casements than the more common stormproof casement. On this type of window the casement section sits in the outer frame of the window. This gives a lesser resistance to draughts and water ingress than the stormproof style. The traditional type is generally only seen on listed buildings and very old properties in conservation areas.

 

The diagrams below shows through sections of a traditional window construction. Please do not rely on the information in the diagrams; they are for illustration only.

  

Stormproof casement construction

Stormproof casements protrude out infront of the frame as can be seen from below. The casements are hung on specialized stormproof butt hinges. On this type of window the casement section overlaps the outer frame of the window. This gives greater resistance to draughts and water ingress than the traditional style.  This type is now the standard for all windows and you generally only find the traditional type on listed buildings and very old properties in conservation areas. 95% of our windows are made in this style.

Hardwood timber selection

Below is a selection of hardwood timbers that you can choose from (pine is also an option, but is not shown):-

Oak

Iroko

Sapele

Idigbo

Douglas Fir

 

Idigbo

This is a light coloured hardwood ranging yellow to light brown, perfect to accept most stain colours. The graining is fairly regular and the timber accepts most treatments well. This is a soft to medium hardwood, moderately durable, with a typical density of 560kg/m³ when kiln dried. Idigbo seasons well, with little distortion and splitting, and shrinkage is small.

This is an excellent for a lighter coloured finish without the expense of Oak.

Sapele

This is a mahogany hardwood which is usually deep reddish brown. Sapele is characterised by a marked and regular stripe, particularly pronounced on quarter-sawn surfaces. Occasionally mottle figure is present, It is fairly close textured, and the grain is interlocked. Its density is about 640 kg/m³ when kiln dried. Sapele will take most stains and polishes well. It is a good hardwearing hardwood and is fairly oily which makes it very good for external joinery. Most hardwood joinery we make is made in this species.

Douglas Fir

The timber colour is usually light reddish-brown in colour. The abrupt change and contrast in colour between early-wood and late-wood bands, produce an attractive grain effect. The average density of dried timber is about 530 kg/m³ Compared with European redwood, it is some 60 per cent stiffer, 40 per cent harder and more resistant to suddenly applied loads, and 30 per cent stronger in bending and in compression along the grain. The timber is durable and will accept most treatments well. Douglas Fir will give a nice light finish with stain and unlike most hardwoods will also paint well.

Iroko

Iroko’s colour is usually golden-brown, but as pictured to the left can vary quite dramatically. Most is like the bottom shade of the picture. The grain is usually interlocked and the texture is rather coarse but even, and the wood weighs on average 660 kg/m³ when dried. This timber is very durable and is quite oily. This makes it superb for all exterior joinery. With its oily properties, generally the timber will only accept stains, but can be painted with specialist primers. When selecting the timbers during manufacture we would try to minimise colour variance, but there will undoubtedly be some.  

European Oak

Oak is normally an attractive light brown colour and is a fairly constant shade. The graining is usually regular and quite distinctive. The density is usually 720kg/m³ when kiln dried. The timber is very durable, distinctive and will accept stains and oils very well.

All hardwoods will have some colour variance. When we manufacture in hardwood, we try to keep this variance to a minimum, but it cannot be eradicated totally. The most noticeable variance is with Iroko as pictured above, but we would try to match this up as much as possible during manufacture. We will not be held responsible for timber mismatch. If you find the mismatch too much the use of dyes and stains will help alleviate this problem.

Should you wish to paint your hardwood window,  you will need to use specialist primers (with the exception of Douglas Fir) . This is due to the naturals oils in the timber. This is especially apparent in the iroko hardwood.
