Mark Two Windows situated in Knapton. The double glazing trade, and the building trade on the whole, hasn’t always had the most effective reputation. But issues have modified! Lately and rather a lot has been achieved to introduce some safety for consumers. However what is the safety, and in practical phrases what does that imply for you as a buyer?

In the United Kingdom there are two professional organisations that monitor and regulate the double glazing industry.

The building regulations state that any replacement doorways or home windows MUST meet energy saving standards. This includes the materials and the installation. When you make use of a FENSA registered firm, you recognize that these rules have been met.
