How Hot is a Glass Extension?

Glass Extensions or high glazed elevations will allow a lot of natural light into a space form the sun. These elements will also allow radiation from the sun into a space which will warm the internal faces, increasing the internal temperature.

Adequate ventilation, Solar Control Coatings, External Blinds or Electro Chromic Glass will reduce the effect of 'Solar Gain' and keep glass installations cool when required.

Will I get a Warranty?

All Minimal Windows come with a standard 5 year warranty. IQ's design is covered PI insurance.

How do I Protect Myself from Glazing Companies Going Bust?

Research the company you will be trading with to ensure it has a firm financial foundation, speak to the company's bank manager and accountant to get a good understanding of its financial standing.

On larger value projects you may want to consider taking out a payment bond for the work to be completed or a cross company guarantee to protect the work.
