uPVC is unplasticised polyvinyl chloride. It is a favourite amongst homeowners and manufacturers for its cheap production cost and excellent benefits. uPVC is used for window frames, conservatories and doors. In fact, uPVC can be three times cheaper than wooden frames and is also the most energy efficient option.As well as this, uPVC is now available in a range of colours other than the typically seen bright white finish. It can also be recycled, is durable and resistant to changing weather conditions.
All new windows come with an energy efficiency rating from A to G. A is best, while G is the lowest rating. Anything above C is considered good, but these days most companies will be able to supply you with A-rated windows to maximise your energy efficiency.
The energy efficiency of windows is measured using ratings, varying from A, the most efficient, to G, the least efficient. This scheme is run by the British Fenestration Council (BFRC). To comply with Building Regulations you’ll need windows of energy efficiency at least level C.
Ultimately the double glazing company you use is responsible for the quality of work and to ensure your windows are of an excellent standard. This is why it’s important to get a warranty and use a Fensa registered installer. If problems emerge within a couple of years then it’s likely the installation was of a poor standard.Contact the double glazing company and have the issue repaired or new windows replaced. This doesn’t matter if you received a discount of free windows as part of the deal. As long as you entered into a contract the company is obliged to restore the windows.
We can help you get more secondary glazing work with our qualified job leads and boost your business.
