It is a myth that roller window screens are effective at reducing glare, according to a new study by researchers at the University of New South Wales and University of Melbourne.
In fact, roller window screen curtains are more likely to create glare and increase motion blur than conventional curtains, the researchers found.
Researchers from the University in NSW, the University at Adelaide and the University College London used data from the Australian National Institute of Health and Welfare to test the effectiveness of roller window displays for reducing glare.
Their research shows that roller windows can reduce glare by up to 60 per cent compared to curtains of similar material.
However, they also found that roller curtains were less effective at lowering motion blur compared to conventional curtains.
“In reality, the effectiveness is not as good as we think,” said Dr Robert Smith from the Centre for Photovoltaic Technologies at the university.
“The screens work by reducing the amount of light reaching the screen and the amount we see on it.
But they also reduce motion blur.”
The researchers also tested two types which were coated with polyethylenes which are both transparent and have a different light absorption pattern. “
The rollers are less effective in reducing motion blur” In the study, researchers tested six different types of roller curtains, which included two types of curtains made from polyethylene, which were made from paper, polyester, polyurethane and polypropylene, and two types made from cellulose and polyethylenimine.
The researchers also tested two types which were coated with polyethylenes which are both transparent and have a different light absorption pattern.
“Each type of curtain has its own strengths and weaknesses,” Dr Smith said.
“Our results show roller window covers have a similar light absorption profile to conventional curtain covers, but their light absorption is lower.
The film is thinner and therefore more susceptible to thermal runaway.”
This is particularly important as a film can be exposed to the sun and heat up quickly in the sun’s rays.”
The researchers then compared the amount and colour of light absorbed by roller window film and curtain covers.
Roller curtains absorbed less light, while curtain covers absorbed more.
Dr Smith also said roller window films were also lighter and thinner, which meant they could be used for a wide range of applications.”
These factors could make roller curtains less effective than conventional curtain screens for applications where they are needed for a high-end product.””
Roller curtain covers are lighter and more efficient, but they have a higher cost to make, and they also do not perform as well in low-light environments.”
These factors could make roller curtains less effective than conventional curtain screens for applications where they are needed for a high-end product.
“Dr Smith said the rollers were more effective in lowering motion than curtain covers because they do not have a rigid frame to absorb heat.
He also said that roller film had a higher light absorption than curtain film, meaning it could be more effective for indoor lighting.
While the roller curtains were more efficient than curtain screens, Dr Smith believes that the cost-effectiveness of curtain screens is a concern.”
I don’t think the cost is the issue, it is the cost and the time of life,” he told Business Insider.
The researchers say that they will be looking at new ways to further reduce the cost associated with roller window products, such as using cheaper materials and incorporating more advanced manufacturing processes.
Roller window curtains have already been developed by several manufacturers and are available in several different materials, including polycarbonate, carbon fibre, and polyurea.
However, there is still much to be done in terms of the cost per square metre, which is what is used to calculate the effectiveness.
