uPVC Discolouration – What It Is, and How to Prevent It

With so many homeowners looking for ways to cut costs in their daily lives it’s no surprise that the double and triple glazing markets have enjoyed an increase in sales in the past few years. These windows and doors offer increased energy efficiency, comfort in the home and decreased utility bills, making them a win-win for any homeowner.

When making an investment of this size naturally you want to see long-lasting results and maintain the same aesthetic values that the item had when first purchased. So for homeowners who begin to note uPVC discolouration in their double or triple glazing, the effects can be heart wrenching.

uPVC Discolouration – The Facts

Double glazing has been around since 1930, but didn’t begin gaining popularity in the UK until the late 1970’s and early 1980’s. The purpose for this delay in sales momentum was due largely to the extravagant expense of these windows and doors, making them an impossibility for most homeowners. In the 1980’s and 1990’s, however, the use of aluminum and uPVC frames changed the scales, making double glazing more affordable for the average Joe.

uPVC in particular offers a high energy efficiency and is more durable than aluminum. One unpleasant side effect that homeowners who purchased early models of uPVC double glazing began to note, however, was uPVC discolouration. Indeed in time the materials will begin to break down or require maintenance with any item, but to make such a large initial investment only to see this effect some time down the road began to make some homeowners weary of purchasing uPVC frames.

Fortunately with newer models of uPVC double and triple glazing manufacturers have rectified the discolouration problem. As a result many now offer lengthy warranties, some lasting as long as 15 years, as an added comfort to homeowners that it is safe to purchase these frames.

Preventing uPVC Discolouration

There are ways to prevent your early model uPVC double glazing from discolouring. Of chief importance is the items that are used to wash the frames. Many homeowners make the mistake of assuming that any old household cleaner will do the trick, but in fact anything more abrasive than soap and water can harm the windows and cause discolouration.

Also take care to use only a non-abbrasive cloth or sponge when cleaning to avoid scratches in the frame. uPVC cannot be painted, so proper maintenance is crucial to enjoying the same aesthetic values in these windows for a prolonged period of time.

uPVC frames are an inexpensive alternative to wooden frames for double glazing. In their early manufacturing problems were discovered with discolouration that have since been modified in later models of the product, giving today’s homeowner in the market for double or triple glazing a less expensive framing option that will still provide enhanced efficiency.
