Thermotek Windows did a fantastic job with the replacement of my old timber windows to new uPVC double glazed windows. The large fixed picture windows which no-one else was really interested in installing really made a huge difference in opening up the space and giving us the result we desired.
Tom and James did a brilliant job installing the windows and the finish was of the highest quality. Their operation was very professional, clean and tidy throughout.
We are enjoying the increased comfort levels we experienced immediately.
We highly recommend the product!’ – David
Customer had old timber windows that didn’t meet any thermal requirements, the old timber windows were rotten and needed to be replaced ASAP.
uPVC double glazed windows & our customised 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.

SPECS OF THE PRODUCT
The customised IGU (insulated glass unit) used, is made up of a 4mm Low E pane with a 16mm argon gas filled gap and 4mm pane on the outside.
Using our uPVC double glazed windows & doors we can achieve a great u-value of 1.7. 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!). The solar heat gain coefficient or SHGC is also nice and low at 0.37. 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.
