Thermotek Windows

We think our new double glazed windows are amazing! This is probably no surprise to a lot of you who live in the northern hemisphere, but down under, double glazing is not the norm. In fact, here in Australia, it is a rarity. Our building codes do not require them to be installed in residential buildings, which I believe is a massive regulatory stuff up. Due to our hot climate, I think they should be mandatory. Since we had our north facing windows replaced and had double glazed uPVC units installed a couple of months ago, our north facing rooms have been warm on cold days, and cool on hot ones. The difference in temperature from what these rooms used to be like is just incredible. Combine that with the ceiling insulation top-up. our home is now very comfortable and has a stable temperature inside most of the time.’

what customer say about us

The Problem

The Problem

Customer had old single glazed windows that really let them down on days that they either needed to warm up the house or cool down the house. The main issue was thermal. They were also an eye sore and didn’t “look the part”.

Our Solution

Our Solution

We recommend Golden Oak uPVC double glazed windows, The double glazed unit will make a terrific thermal difference, the argon gap between the panes dramatically reduces transmission of both heat and sound. The uPVC frames have many great benefits, they provide high efficient thermal insulation, effective sound insulation, high in security & vertically maintenance free, ( just to name a few ).

The standard IGU (insulated glass unit) used, is made up of a 4mm pane with a 16mm argon gas filled gap and 4mm pane on the outside.

Using a standard uPVC double glazed window we can achieve a great u-value of 2.3. The u-value is the amount of heat transferred through a material. The lower the U-value, the slower the rate of heat flow and the better the insulating quality ( therefore the lower the u-value the better!) To give you a rough idea of how great that result is a standard single pane window generally sits around the u-value of 6.

The solar heat gain coefficient or SHGC is also nice and low at 0.43. This is the percentage of heat gained from both direct sunlight and absorbed heat. Again smaller the number, the greater the ability to reduce solar heat gain.
