U-value is a measure of heat transfer/loss in a building element. Lower U-values indicate higher
levels of insulation.

Dowell ThermaLine™
HIA PRODUCT OF THE YEAR


For generations, the Dowell name has been synonymous with creating innovative window and door solutions in Australia.


Holding true to its name, Dowell added a sliding door and four new energy efficient windows into its ThermaLine™ range; the awning, multi‑transom awning, sliding, and fixed windows. These windows and doors herald a new era in affordable, energy efficient design and in 2012 was awarded the HIA GreenSmart product of the year award.

HIA Judges stated; “ThermaLine™ Windows are a versatile, high performing and cost effective aluminium window range. The new ThermaLine™ frame has a similar thermal performance to the installed glass. With Uw-values* as low as 1.7, the windows are rated the best in its class. The low Uw-values benefit homes with large amounts of glazing to achieve 6 stars or better. The product range consists of an awning window, fixed window, slider window and sliding door designed to be a cost effective solution for energy savings to the residential housing market.”


*Uw-value relates to the entire window and incorporates the U-values for the glazing ‘Ug’ and the frame ‘Uf’. Reference source: Window Energy Rating Scheme [online] Available: www.wers.net.au, based on double glazed thermally broken aluminium windows and doors (13 November 2014).

 


 

 

Dowell ThermaLine™
ASTHMA FRIENDLY


Dowell ThermaLine™ windows and doors have been approved by the National Asthma Council Australia’s Sensitive Choice® program. The Sensitive Choice® blue butterfly symbol is a way of recognising products and services that may be better for people with asthma and allergies.

Assessed by an independent panel, products and services carrying the butterfly have attributes that assist with reducing exposure to triggers.

Dowell is supporting the National Asthma Council Australia’s efforts to improve asthma and allergy care.

In choosing a Dowell ThermaLine™ window or door you are choosing to lower the likelihood of condensation formation, thereby lowering the risk of dust mite and mould growth.

The Dowell ThermaLine™ range has exceptional
air infiltration performance – an important factor if the conditions inside a home are to be strictly controlled.

Dowell ThermaLine™ windows and doors are double glazed, thermally broken aluminium frames. All Dowell ThermaLine™ products have been independently tested and verified in accordance with the Australian Window Association Windows Energy Rating Scheme (wers.net.au).

 


 

 

Dowell ThermaLine™
COMFORT


The Dowell ThermaLine™ window and door product range consistently produce very low Uw-values.


During winter or in cooler climates Dowell ThermaLine™ windows help reduce cool air entering the home and help keep warm air indoors. Condensation is reduced considerably, which often occurs as a result of large differences in temperature between the interior and exterior environments.


In summer or warmer climates Dowell ThermaLine™ windows help act as a buffer against the hot air outside, minimising the transfer of heat into a building. Dowell ThermaLine™ will help minimise the loss of cool air, reducing the size and need for air-conditioners.

Solar Heat Gain Co-Efficient (SHGC) is a measure of how much solar radiation passes through a window. For comfort during the summer months, the smaller the SHGC the better.


With SHGC’s as low as 0.18* for the hotter climates and SHGC of 0.55* for the cooler climates, the Dowell ThermaLine™ range will help provide comfort in a home year-round and reduce the need for air-conditioning at home.
