Is Triple Glazing Really Worth It?

Double Glazing can make a drastic improvement in thermal comfort when compared to single glazing, however, can the same be said for Triple Glazing? Let’s consider a few things and determine if Triple Glazing is truly worth the extra expense.

Double Glazing - IGU

Cost of timber

We typically manufacture doors and windows from 50mm thick Accoya, allowing us to get a finished thickness of 45mm. This gives us enough room for a 34mm rebate which permits double glazing. To move up to Triple Glazing, we need a rebate of 50mm. To achieve this, we need a finished thickness approximately 65mm, which can be machined from 75mm thick timber. Thus, there is approximately 50% more cost in timber.

Cost of Glazing

Triple Glazing Units start at approximately 50% more than double Glazed. So, this means that aside from the cost of timber, there is also more cost to be accounted for in the glazing itself.


Finally, the big one, thermal performance. Ultimately, we want to achieve maximum thermal efficiency to reduce ongoing heating and cooling costs. However, the minor improvement in thermal performance for Triple Glazing may be less than you think.

For this purpose, we can compare glazing options for a 900 H x 600 W Stormsafe Casement Window.

When we run a simulation for this window with 4mm Clear Float Single Glazing, we return a U Value of 3.8 and SHGC of 0.51.

For this same unit in Double Glazing (4 Clear-10 Argon-4 Clear) we return a U of 2.10 and SHGC of 0.45.

Now, it gets interesting when we utilize Lightbridge Double Glazing (4 Clear – 10 Argon – 4 Clear Low E) and return U 1.56, SHGC 0.35. These values are quite impressive and achieved with affordable Double Glazing.

Finally, we can look at an entry level Triple Glazing option (4 Clear – 12 Argon – 4 Clear – 12 Argon – 4 Clear), for which we see a U of 1.65 and SHGC of 0.41 and if we upgrade this to incorporate a Low E coating, we get a U of 1.39 and SHGC of 0.32.

Our Recommendation

The performance values we can achieve with Lightbridge DGUs are better than entry level Triple Glazing, and at a fraction of the price. This option is suitable for harsh climates throughout Australia. We recommend Lightbridge Double Glazing as the best return-on—investment for glazing. Triple Glazing with Low E coating can perform slightly better than Lightbridge Double Glazing, but the performance increase is not near as significant as the cost increase.

Double Glazing


Double glazing is becoming increasingly popular among homeowners who wish to create an energy-efficient & comfortable home. This type of glazing involves having two panels of glass installed in a window or door frame, creating an air gap between them. The air gap acts as an insulator, helping to reduce heat loss and keep your home warm in the winter, and cool in the summer.

Why is double glazing important for an energy-efficient home, you might ask? There are several reasons, all of which contribute to lowering your energy bills and reducing your carbon footprint.


Firstly, double glazing is an excellent way to reduce heat loss. Single glazed windows & doors can lose up to 20% of a home’s heat. In contrast, double glazing can reduce this heat loss by up to 50%, making it a very effective way to keep your home warmer for longer without needing to continuously use your heating system.

This means that, with double glazing, you can use your heating system less frequently and at a lower temperature, resulting in significant savings on your energy bills. In addition, when you use your heating system less often, you reduce your carbon footprint, making your home more environmentally friendly.

This same principal applies to cooling. Double glazed windows can reduce the amount of heat entering the home and decrease the demand for a cooling system. This can be enhanced with the addition of a low E coating as incorporated into systems such as Lightbridge, by Viridian.


Double glazing can also help to reduce external noise pollution, which is especially important if you live in a busy area or close to a main road. The air gap between the two panes of glass acts as a barrier, reducing the amount of noise that enters your home.


Another benefit of double glazing is that it can help to increase the security of your home. The two panes of glass are held in place by a frame, creating a strong barrier that is much harder to break than a single pane of glass. This means that, in addition to reducing your energy bills and carbon footprint, double glazing can also help to give you peace of mind and improve the safety of your home.


In conclusion, double glazing is a crucial consideration for an energy-efficient and comfortable home. It helps to reduce heat loss & gain, external noise pollution, and increase the security of your home, all while lowering your energy bills and reducing your carbon footprint. With so many benefits, it’s easy to see why double glazing is becoming increasingly popular among homeowners who want to create an environmentally friendly and cost-effective home.

Kitchen Design

The basics of kitchen design

Kitchen design can be daunting at first, but with professional guidance it can be a fun experience. At the Joinery Store, our expert team can assist with your kitchen design and provide high quality 3D renders for your convenience.

When planning a design it is important to balance function with aesthetic. It is a good idea to start by considering the space available to fit your new kitchen and then how you as as an individual, would work within the space. Each home is different. Some people love to bake and require multiple ovens whilst others may not cook much. Some kitchens need to serve a large household, and some may only need to be suited to a single individual. Think carefully about how your design will need to be orientated to serve your needs.

Once you are aware of the space available and how the kitchen needs to function, you will need a style and some inspiration. Using Google Image Search, you can search phrases like ‘Modern Kitchen’, ‘Scandinavian Kitchen’ or ‘Traditional Kitchen’. This will result in thousands of photos which can inspire your vision.

Engaging a Professional

Once you have a basic understanding on the direction you are headed with your design, it’s a good idea to engage a professional. If you are struggling to even come up with an initial layout or style, a professional can also help guide you through the most basic components of the design. However, the more information in terms of ideas and inspiration references you can give the professional, the more efficient the process may be.

A good professional designer will be able to design a layout that balances functionality and style, whilst fitting your needs. They should be able to provide plans or images of some description, which reflect this design.

At the Joinery Store, we utilize modern CAD software to prepare 3D renders for our clients, such as those shown in the gallery below. This helps our customers to get a good feel for the design and a visual of the aesthetic.

Best Timber for External Doors and Windows


In this article we compare common timbers used, to determine which may be considered the best timber for external doors and windows.

The timbers we will be comparing will be Western Red Cedar, New Guinea Rosewood and Accoya. We will be comparing them based on multiple factors such as stability, longevity and coatability.

Hardness (Jenka)

The first character we will be comparing is hardness. This is an indicator of the surface durability of a timber and is measured using the Jenka system.

When comparing the three timbers we are investigating, we find that Western Red Cedar Typically has a low Janka hardness of 2kN, New Guinea Rosewood has a moderate Janka hardness of 5kN and Accoya has a moderate Janka hardness of 4.1 kN. This makes Rosewood the hardness option with Accoya close behind, whilst WR Cedar is quite soft. Due to it’s softness, Cedar may mark quite easily whilst Accoya and Rosewood will not mark as easily.

Estimated Service Life

The estimated service life of a timber is the timespan it is expected to perform it’s purpose to a satisfactory standard. Timbers are classed by their estimated Service Life with Class 1 being timbers with a service life of 40+ years, Class 2 being timbers with a service life of 15-40 years, Class 3 being timbers with a service life of  7-15 years and Class 4 being timbers with a service life of 0-7 years. These periods being based on outdoor use of the timber, above ground.

Both Western Red Cedar are Class 2 Timbers with an estimated service life of 15 – 40 years. Accoya on the other hand is a Class 1 timber with an estimated service life of 40+ years. Thus, out of the timbers investigated, Accoya has the longest Estimated Service Life.

Coating, Painting

When considering how suitable a timber is for painting, we need to look at multiple factors including how stable the timber is (Will it move and split the paint) and how likely it is to bleed tannins which may discolour the paint.

One way we can determine how well a timber will support a painted coat is by looking at the radial shrinkage of the timber. This is the amount the timber may move along the growth rings (Shrink and expand) which can result in the painted surface cracking. Rosewood has a radial shrinkage of 1%, Western Red Cedar has a radial shrinkage of 1.5% and Accoya has a radial shrinkage of 0.4%. This makes Accoya the most stable when it comes to shrinkage.

When we look at tannin and leaching, both Western Red Cedar and New Guinea Rosewood may stain the paint causing discolouration. For this reason they are best sealed and painted with an oil based paint. Accoya on the other hand, does not bleed or leach and so it can also be painted with water based paints.

With these factors considered, Accoya is the most suitable timber for painting.


Considering the above factors, we find that Western Red Cedar is the least hard, durable and suitable for painting of the three timbers investigated. Rosewood is the hardest, but is not the most suitable for painting and is only a Class 2 timber. Accoya proved to be the best for painting and is a class 1 timber which also boasts a hardness not far behind Rosewood. For these reasons, we conclude that Accoya is the best Timber for external doors and windows.

Metamerism and Colour Inconstancy in Painted Finishes


When comparing painted surfaces, colour inconsistencies are often observed. These can be inconsistencies between different paints which have been colour-matched, or with different surfaces painted in the same paint when viewed under different conditions. In this article, we explore when, how and why this happens.


Metamerism describes the way two coloured surfaces may appear colour-matched, or non Colour-matched, depending on the light under which they are viewed. This phenomenon results from the varying spectral power distributions of the surfaces.

In one case we had a client report that their windows had discoloured over time. We prepared freshly painted sample pieces of timber and took them to site as control tools. When we placed these sample pieces against the windows, they were perfect matches. However when we took the pieces away and looked at them under direct light, they appeared whiter than the windows. This was a result of metamerism as the paint colours were a perfect match when in the same light, and only appeared different when observed under different light.

Metamerism is common in painted surfaces as different paints have different formulations (Different pigments used etc). For this reason, paint matching is not a perfect art and inconsistency in colour is common. The below video explains metamerism whilst provide visual aids to demonstrate this effect.

Viewing Angle and Shading

The viewing angle also affects the appearance of a surfaces colour, along with the shading of surrounding objects.

In one experiment, we sprayed a window frame with a RAL 9010 (Pure White) coloured paint. We viewed the frame when stood upright and observed that the inside faces of the sides appeared whiter than the sil, which had a creamier appearance. However, when we then rotated the frame, the colour appearance adapted accordingly. The inside face of the side of the frame now appeared cream, whilst the sil appeared whiter.

This can happen because each piece is subjected to different lighting and shading. It is therefore metamerism as we explored above, resulting from the placement of the piece being viewed, and the respective viewing position. But in this case, we are seeing how the same paint changes it’s colour appearance when subjected to different lighting and shading, rather than comparing two different paints.

Metamerism Example 1, Colour Inconsistency
Metamerism Example 2, Colour Inconsistency

Sheen Level

Sheen level is another factor which can affect the appearance of a paint. Let’s say you try to colour match two paints. Each paint is tinted to the ‘same colour’, however one has a sheen level of 30% and the other has a sheen level of 60%. The two paints may appear to be different in colour as a result of how glossy and reflective they are. The 60% sheen paint may reflect more colour from the surrounding environment and appear glossier whilst the 30% paint may maintain it’s own colour to a greater degree and appear less glossy.

Paints with a higher sheen level also can often appear darker than the equivalent colour in a low sheen paint. The below article from Dulux Australia discusses this matter.

Environmental Factors

Environmental factors can also affect the colour of a paint. Depending on the paint and the environment it is subjected to, it may discolour as a result of being subjected to direct sunlight or moisture.

On a couple of occasions we have observed painted surfaces that have been discoloured by environmental factors such as pollen and dust. In one particular case, our customer reported that their white paint had yellowed. The paint we use is non-yellowing and so we were not surprised when we attended the site to discover that a yellow substance had stuck to the painted surface. We speculated from observing the surrounding environment, that it was yellow pollen. We were able to simply wipe the suspected pollen from the surface of the paint, revealing the true paint colour underneath.

As an experiment, we have painted test pieces of timber in matching paint then stored them in different locations over a period of a few months. One piece in direct sunlight, one in the dark of a cupboard and one subject to the ambient light in an office. At the end of the test period when we compared the samples side by side, they all matched perfectly. No discolouration had taken place with the paint we used under these conditions.

Key Takeaways

When trying to colour match paints, we must be mindful of the above factors. It is always advisable to for the customer to compare paint samples under different lighting in different locations before settling on a selection when colour matching is a concern.

As with the above, when settling on a paint colour selection, it is best to view it under different light and at different positions and locations, to consider how the appearance of the colour may vary.

Pre-Finished Doors & Windows

Green Ledged & Braced Door

What are Pre-finished Doors & Windows?

At The Joinery Store, we specialize in pre-finished Doors and windows. These include the operable components (Window sashes, door leaves etc) pre fitted in jambs/frames.

These units come coated (Painted or stained) and glazed, with hardware pre-fitted.

To achieve this, we manufacture the doors and windows and fit the hardware. We set the door or window up in a controlled environment, and test for functionality. We then disassemble the units and send the timber components into our spray booth to be coated. Once they are coated and dried, we can glaze any sections required then reassemble the units before subjecting them to a final quality control process.

How does this compare to other Timber Doors & Windows?

Most common doors and windows come uncoated, or primed ready for painting. They are then to be painted on site after they have been installed. Unlike our pre-finished units which do not need to be painted or stained on site.

Sometimes timber doors and windows will come pre-glazed, and other times they will need to be glazed on site after they have been installed, depending on what the manufacturer offers. We glaze our pre-finished units during manufacture, before they go to site.

Sometimes windows will come pre-fitted with hardware. Usually doors will come as loose-leaves without hardware, for the carpenter to fit into the jamb on site. Our pre-finished units are completely fitted within the frames/jambs, with necessary hardware. We can supply this hardware, or fit hardware supplied by our client

What are the benefits of Pre-Finishing?

Our Pre-finishing process provides a range of benefits, including:

Paint/Stain Coverage. As we spray the components in a controlled setting before reassembling and glazing the units, we can ensure all exposed timber is sealed as required. As these coatings are sprayed on, we can achieve a wet film thickness of around 170 microns per coat. For comparison, a brushed or rolled coat would typically be 30 – 50 microns thick. Our coating is even, seals the end grains of the timber and is environmentally friendly.

With our windows and doors pre-fitted and operational, there is much less work to be conducted on site. The carpenter simply needs to fit the finished unit into the opening and it should function optimally with minimal adjustments required.

Quality Control. As we are responsible for the majority of the work involved in finishing the unit, we can maintain a high degree of quality control. We ensure our units operate correctly before they leave the workshop. We also use superior timbers and coating systems such as Accoya Wood with Teknos Paints and Stains.

Disadvantages of units that aren’t Pre-Finished

*More work required on site for carpenters, to assemble, install unit and make it functional.

*Painter Required to coat timber on site. This can result in uneven coverage, sashes and door leaves sticking to each other and unwanted mess.

*If the unit is painted after it has been glazed, painting inside the rebates and back of glazing beads is not possible

*Lesser Quality Control

*Possible need for Glazier to glaze onsite

*Inferior products likely to be used, such as the timber and paint

Accoya Decking

Which timber is best for decking?

Timber is a popular choice for outdoor decking as it can provide a naturally aesthetic and comfortable surface. You may find yourself asking what is the best timber for outdoor decking. Well Accoya might be the answer you are looking for. Let’s take a look at some of the characteristics of Accoya Decking.


Accoya is a highly durable timber. It is a ‘class 1’ timber meaning that it expected to last over 40 years outdoors and it has an estimated 70 year minimum service life. It even comes with a 50-year above ground guarantee.

Accoya is suitable for all kinds of climates and is less prone to warping, cupping or bowing than common timbers such as  spotted gum and merbau. It is resistant to both rot and splintering.

Thermal Comfort

Another thing to consider when selected decking is the thermal or ‘heat’ gain. This will affect how hot the decking gets when exposed to ambient heat and sunlight. Accoya has a low thermal gain as compared to other decking products and so this can make it much more comfortable to step onto within burning bare feet.

Pest Resistance

Accoya is resistant to pests such as termites which may otherwise consume the timber, breaking down your decking. However it is still non-toxic not relying on toxic insecticides to achieve this property.


Accoya is suitable for coatings such as paints and stains. The stable nature of the wood can preserve the coating meaning a greater span of time achieved between coatings.

Final Words

Accoya is a versatile timber which offers a range of benefits. The unique properties of Accoya make it a great option for timber decking. If you would like a quote for Accoya Decking, please contact us.
