How to look for quality in the suggested products?

You must look for products that are certified CSA and ENERGY STAR. This will ensure you that they have been tested by an independent laboratory and that they will provide energy efficiency and savings.


How to recognize a CSA rated product?

Isothermic Doors & Windows Inc. has had all of its products tested and approved by the CSA.


What does Energy Star means?

The Canadian ENERGY STAR program for doors, windows and skylights enables you to choose ecoENERGY products. The Canadian territory has been divided into four climate zones: A, B, C, and D, the D zone being the coldest. This will help you recognise products that must meet the strictest requirements. Isothermic Doors & Windows Inc. is proud to be an ENERGY STAR partner.


Casement, slider or hung windows? Garden or patio doors? What to choose?

Choose new doors and windows that will correspond to your needs and harmonize well with the style of your house. If you replace all of your doors and windows, you can dramatically change the look of your home by opting for a completely different model than the previous one. Call upon a professional representative to help you revise your options within the wide range of models from Isothermic's doors & windows.


What is Low-e glass?

Low-emissivity glass (Low-E) is a double or triple insulating clear unit, to which an invisible metal coating has been added, letting the outdoor light in but retaining the radiant heat originating from indoors. Low-emissivity glass can be combined to argon or krypton gas. However, because of its high cost, krypton gas is not commonly used, but is the most insulating. The principal advantage of having low-emissivity glass is energy savings. Besides diminishing the cost of heating during winter, this insulating glass will reflect away the sun radiation, thus, reducing air conditioning costs in the summertime.


Will windows with Low-E prevent condensation?

Fogging and frosting are common problems related to windows. They can appear as light vapour, or persistent frosting that covers the whole indoor glass surface. Many home owners will buy and replace their windows only to see this problem worsen. Condensation appears when the indoor humidity is cooled to the point of forming vapour or frost on cold surfaces such as windows. One solution is improving air circulation to reduce the indoor level of humidity. You will find solutions on the Canada Mortgage And Housing Corporation (CMHC) website.


What do I do if I have a problem with my Isothermic door or window?

The first step is to contact the retailer where you bought your Isothermic product. Afterwards, an aftersales service will be requested and a qualified technician will be sent to your residence for repairing.
