How to Buy Double Glazing

How to Buy Double Glazing
  • Opening Intro -

    If there is one product that has fallen into disrepute over the years, it is double glazing.



This is hardly surprising considering the unscrupulous sales methods and marketing tactics used by salespeople, but it has unfortunately made people very wary of an otherwise great product.

In this article we are going to discuss a few things you should remain aware of when making you purchase; double glazing can make a great addition to your home, reducing your heating bills and blocking out unwanted noise, so here are some ideas to help make the buying experience a much smoother one.

Do Your Homework

In this digital age, we have at our fingertips the single greatest research tool – the Internet.
There really is no excuse to remain ignorant of unsound businesses with the advent of comparison websites, and checking up on providers before speaking to them can save you a considerable amount of time and stress.

Always remember that the bigger and better established a company is, the more customers it is going to have dealt with; no business is going to be absolutely perfect all of the time, even simply due to basic human error, so keep a keen eye when looking at consumer reviews and wheedle out the minor grievances – “My installer was five minutes late!” – From the major deal-breakers – “My provider damaged my patio door and refused to compensate me for it because it wasn’t covered under their insurance policy.”

Certification and Guarantees

Organizations such as FENSA and CERTASS offer companies the chance to become self-certificated, thereby circumventing the requirement for an independent inspection to be performed by the local authority.
If your double glazing installer is registered with one of these schemes, you can be fairly confident that their products will comply with current thermal performance standards, but if you are still in doubt, you can arrange for an inspection to be performed by a third party.

The company should hold an insurance policy which protects you if they damage your property, install defective products, or go bust altogether, and this policy should back up a guarantee on all of their products – this will usually provide you with between five and ten years of coverage.


As well as researching the company itself and being mindful of sales tactics, you should also pay close attention to the team that will be installing your windows.

Even if the sales process has gone swimmingly up to this point, the installation process is the most pivotal point in the whole sequence and this is where things can seriously go awry if your double glazing is not correctly installed because of an inexperienced or neglectful team of installers.

Ideally, you will choose a company who uses their own dedicated installation team to perform all of their work, but some will subcontract the work out externally.

Subcontractors are not necessarily a bad thing but you should certainly do a little extra research to make sure that past customers were happy with their performance.
