Double-glazing a conventional window costs $489, while the same window treated with ClearComfort insulating membrane costs only $24!

Frequently Asked Questions

How do I clean it?
The membrane is easily cleaned - just wipe over the surface using a soft cloth dipped in warm water only. Add a few drops of detergent to the water if the surface marks are greasy and then rinse off with clean water. DO NOT use chemical cleaners or abrasive cloths.

It looks like it is very thin - how easily is it damaged? What happens when you bump it? What about children poking it?
Yes, the membrane is very thin (25 microns) but very tough and tear-resistant. It will bounce back if poked, pushed, bashed - even if you break the glass behind it.
However, it can be damaged by slashing with a very sharp object such as a razor blade, and will melt if a naked flame is applied to it (however, it is not flammable).

How much space is optimal between the window and the membrane?
The optimal air gap is anywhere between 10 mm and 20 mm, however a wider air gap (up to 100 mm) will still provide effective window insulation. Less than 10 mm and you run the risk of the membrane (which is flexible) adhering to the window glass.

How much is noise reduced after installation of your product?
The ClearComfort system is highly effective in reducing heat transmission but does NOT provide sound insulation.

Is there a problem with condensation in the sealed air gap?
This can occur but is preventable.
To avoid condensation in the sealed air gap we recommend applying the membrane system when the air humidity is low. You should also check that there is no moisture trapped between the glass and the frame, that windows fit properly into the frames, that timber is well seasoned, and that any paintwork or silicon sealant is thoroughly cured.
If you discover condensation between the membrane and the glass, it can be removed by carefully lifting a small area of one corner of membrane to allow air movement. Wait for a day when the humidity is low, and then re-seal the membrane to the corner.

Can it be used on the outside of a window?
Ideally you should place the membrane on the INSIDE frame of the existing window, however in a protected outside location (e.g. under the eave and perhaps behind an insect screen) it will perform almost as well as on the inside.

I'm no handyman. How difficult is it to install?
We assume the person applying the product has basic household skills. For example, people who enjoy a hobby such as sewing or fixing simple things around the house should have no difficulty in applying the materials. Basic carpentry skills are required for some window types (e.g., sliding aluminium windows). Installation instructions are provided with the kit and are found on our ‘Do it yourself’ page.

Can you come to my house to install it?
We are not able to visit your home to offer assistance. However, installation instructions are found on our web site and detailed instructions are included with every kit. Unless you are dealing with specific types of window, such as sliding aluminium windows, it is a remarkably simple operation. If you have a problem, we can offer telephone support. For illustrated information please refer to our ‘Do it yourself’ page.

Can I remove it once it has been installed?
The tape is designed for permanent use. Removal requires solvents and/or abrasive materials.
If you intend to remove the installation you should use temporary tape, which is the double-sided tape typically supplied by hardware and stationery stores. The tape we supply is designed for permanent installation and is difficult to remove. We supply temporary tape in 33 metre rolls, but you must specify TEMPORARY TAPE in your order.
Please refer to our ‘Prices, orders, contacts’ page.

Is it suitable for sliding windows with older-style extruded aluminium frames?
Please see ‘Aluminium windows’ on our ‘Do it yourself’ page.

Is it possible to apply your insulation system to aluminium windows without having to make the additional timber frames?
That depends on the type of aluminium frames you have. If you have a wide flat surface parallel to the glass all around, like a flat picture frame, with no fins or other projections, and it will provide a gap of at least 10 mm between the glass and the membrane, then you may be able to apply the system to the existing aluminium frames.

Please refer to the pictures on our website to gain a better understanding of the frame requirements.

What is the best way to keep the timber frames in place when used with sliding aluminium windows?
The frames are held in place by friction between the lining* around the edge of the timber frame and the surface of the window reveal.
*one of the self-adhesive weather strip products made for sealing around windows & doors available from hardware stores. We have found RAVEN RP61 Draught Excluder satisfactory.

Alternatively, you could use some sort of clip but it should not be necessary. We suggest making the frames in pairs so that you can remove one frame and place it in front of the remaining frame still in place, thus you can easily access the sliding half of the window.

Do you have a showroom where I can see your product installed?
We sell by mail order so we do not have showrooms. This ensures the price of our product is as low as possible.
We have many photographs of our product on our website, showing windows with the intelligent insulation system already installed, and photographs of the simple installation steps being followed.
If you would like a sample of the membrane, just email us your street address and we will send out a sample.

Our licensed agents may have displays in their showrooms. Please refer to our ‘Agents’ page.

What warranties do you provide?
ClearComfort is covered by normal guarantees, that is, that the product will do what we say it will do. Our products have served our customers well for more than a decade in Australia, and are guaranteed against deterioration. However because the installation is by the customer, we cannot guarantee workmanship.

What are the most common installation problems?
1. The most common mistake is placing the tape on a frame that is too narrow. The tape supplied is 15 mm wide. Frames must provide a flat surface at least 15mm wide (30mm for large windows) in order to provide sufficient area for adhesion when the membrane is under tension after shrinking with the hair-dryer

2. Some enthusiasts neglect to adequately clean window frames that have acquired a greasy surface over the years. Others apply the tape onto unpainted wooden frames not realizing the timber has been treated with an oil or wax protective coating.

Frames painted long ago should be cleaned with a solvent such as methylated spirits.

Oiled or waxed frames, and rough-sawn timber surfaces, must be sanded down to reveal fresh, smooth timber in a 'Dressed And Ready' condition before applying the double-sided tape.

Please refer to ‘Window frames treated with oil, wax, or in poor condition’.

3. Insufficient pressure or inconsistent rubbing and ‘burnishing’ of the tape after the membrane has been applied may sometimes result in the membrane/tape/frame seal failing, and the membrane starts to fall off. This can be avoided by really consistent, firm pressure applied all over the taped surface, as described in the Installation Instructions.
