Why Choose UPVC?

UPVC Windows offer a number of benefits to the homeowner – here are our top 5!

  • Durability and Weather Resistance

    uPVC windows are very durable and weather resistant - they can withstand UV rays, rain, humidity and temperature fluctuations, and will last for many years with minimal upkeep.
  • Energy Efficiency

    uPVC window systems can be installed with a choice of double or triple glazing. This improves insulation, helping to maintain indoor temperatures and ultimately lowering energy bills.
  • Low Maintenance

    Unlike wooden frames which require painting and maintenance, uPVC windows are easily maintained by simply wiping down with soapy water and a damp cloth.
  • Sound Insulation

    If you live near a busy road or just want more peace and quiet, uPVC windows will help. The combination of airtight seals and double glazing significantly reduces outside noise, helping you enjoy a calmer home environment.
  • Security

    Tough, hardwearing materials, together with modern multi-point locking systems provide a high level of security for your home.

Thank you for a lovely job on our windows, doors and porch. We were really impressed with Stacey and Ben who fitted our windows. They did an outstanding job. The windows are really good quality and we are very happy with them. Thank you for resolving the issue we had very promptly. We would highly recommend you to everyone.

We would like to thank you and your colleagues for the fantastic job you did with our front door, we are both thrilled with the finish and quality of your product. The fitter did a good job and left everywhere clean and tidy all at a good price. We will have no problem recommending you and FIS Windows Ltd to friends, family or anybody else that needs windows or doors. Once again many thanks.
Mr & Mrs T Potter
FIS were great from start to finish. No pushy sales but quoted just what we wanted. Measurement and survey and Installation to fit with your schedule. Superb fitting and high quality finished products. Very pleased and would not hesitate to recommend. Definitely not the typical double glazing firm. Will be using again for other requirements. Friendly and helpful at every step.

Terry & Barbara Smith
Dear Pasquale, I just wanted to let you know that we are delighted with the work your company has done to upgrade the conservatory. Craig and Tommy made an excellent impression. They worked very hard and efficiently throughout, as did the other contractors. What is more, they were all without exception cheerful and courteous at all times. It was a thoroughly professional job, and we now have a room which looks great both inside and out, and will serve us well for many years to come. Please pass on our thanks to everybody involved.

Exceptional!! I have just had 18 windows, french doors, a front and a back door fitted. The fitters were first class, always on time, polite, tidy and complete perfectionists. The product is excellent and there was no hard sell. My house has been transformed. I couldn’t be happier and would strongly recommend this company to anyone.
