Why do Eurotech WinDoors® windows open inwards?
To make them easy and safe to clean in multi-storey buildings and to protect the sash from the wind.

How does the price compare to ordinary wooden joinery?
They are about the same price. Please take into consideration all windows and doors are mortise and tenon jointed, completely spray finished with a quality coating and therefore don’t need painting on site, and with all hardware, handles and glass included. What also needs to be taken into account is that our windows and doors are all made from oak or Siberian larch which are much harder wearing than cedar or pine.

What is the difference between others retrofitting double glazing into our old timber sashes against Eurotech WinDoors products?
Retrofitting is normally done by machining a deeper rebate into the sash to insert a new double glazed glass unit. However, the existing sash timber may be in poor condition, warped or not as strong as it used to be. The maximum thickness the double glazed glass unit can be in these old windows is normally 16 mm which is not enough for proper insulation (but is the same cost as a 24 mm unit). In addition there will still be no seal between the sash and frame. The price difference between new windows and retrofitting is, in many cases very similar, so why spend money on retrofitting when you can get brand new sashes and frames?

I want to use a builder – how does it work when I want to use your windows?
We normally deal with both the client and builder when retrofitting, while for new builds, the client, architect and builder will all be involved in the process. We will help everyone along the way and provide drawings and installation instructions when required.

How long do Eurotech WinDoors® windows and doors last?
When maintained, timber has the longest life expectancy compared to any other window material. We replace a lot of 20-year-old aluminium frames with our timber joinery. When we replace ordinary wooden joinery (made of Douglas Fir), the windows are sometimes 80 to 100 years old and still not in a too bad condition. Aluminium cannot rot, but it corrodes and the coating fades. Handles and corner joints are weak points. We expect our windows and doors to last at least as long as the house!

Do you use treated timber?
No, for our frames and sashes we only use durable timber which does not need treatment. Treated timber is not a healthy option – neither for you nor for us in the workshop.

Do you build outward opening doors?
Yes, we can build front entrance doors, side entrance doors, bifold doors and French doors this way.

Why do Eurotech WinDoors® windows and doors look thicker than normal?
This provides a superior thermal value (U-value), strength and resistance against warping and twisting. It also makes them extra-secure and gives better fire protection than thinner, hollow and most doors of man-made materials.

Do Eurotech WinDoors® products have a thermal break? Timber is a natural insulator and provides a natural thermal barrier, unlike aluminium which is highly conductive.

In my house we have to make the wooden windows fit from time to time. Sometimes we call a joiner to do this which costs money. Is it the same with your products?
Our windows are 3D adjustable. The customer only needs an Allen-key to adjust the units with no need to call any professional in. This is especially important in new houses that settle, or most of NZ which is seismically active.

I have heard that timber windows are not suitable for the climate in Central Otago? Is that right?
Once the timber has adjusted to the local surroundings, our timber windows are able to withstand Central Otago’s cold, moisture, heat and strong sun. As a general rule, 20 mm of the exterior is affected by the exterior moisture level and 20 mm of the interior is affected by the interior moisture level. Normal wooden joinery is only approximately 40 mm thick. Our window and door frames are at least 68 mm thick (and up to 112 mm), giving them at least an extra 28 mm of unaffected core. This means our doors are less susceptible to warping. Another important aspect of Eurotech WinDoors® products is the fact that they are three-layered laminated timber which also helps to keep the windows straight and minimises warping and twisting.

Is it possible to retrofit the wireless SecuSignal® system to my windows?
Yes – even after 20 years. Just change the handle (it has two machine screws) and plug in the computer.

My house has got green weatherboards. I would like to match the colour and see natural timber on the inside. Is that possible?
Any colour can be mixed in the Sikkens paint system. It is possible to have different colours for the outside and inside. We can match any Resene opaque colour, but also have many different wood colours from Sikkens available.

Is it possible to use triple glazing in your windows and doors?
Yes, that’s the standard now in some European countries. The glass unit is 32 mm thick for timber windows.

Do I have to pay a deposit? And why?
Yes, we require a deposit before we start producing. This ensures that we can book the factory production when required,  as well as ensure that we have the correct materials (timber, hardware, paint etc) on hand. While we carry a large amount of timber, hardware and paint, most larger jobs require ordering materials from Germany which obviously takes time!

How long does the paint last?
How long the paint lasts depends on many factors- how the units have been installed, how wide the eaves are, how exposed the units are to the elements, whether the units are north facing, location in NZ, a light or dark colour etc…  As a general rule, solid colours will last longer than clear coats, which in turn last longer than opaque colours. Exact length of time is difficult to answer and is often determined by the UV levels and weather exposure experienced in each location. We are constantly working with our NZ and overseas suppliers to improve coating systems. Feel free to ask us on our experience for your area.

When I have to repaint the windows, do I need to sand them down to bare timber like the oil paints of old?
As our coats are water based, and as long as the units have been maintained, as a general rule you will not need to sand down to bare timber. Normally you will only need to lightly sand the outside of the frames and sashes with fine sandpaper (220 grit or more) so the new coat keys to the existing one. Even if the coating has deteriorated to the extent that more stain is required, then sanding is still very straight forward to remove the top coats, apply the stain, and then re-apply the top coats.

Can I use blinds and curtains?
Yes, although please be aware that if you use solid blinds, or thick or thermal curtains when the sun is shining through the glass, the glass can overheat and crack unless it is toughened. Please see regarding thermal breakage.
