FAQ About Double Glazing & uPVC Windows in Belfast

• How much do double-glazed windows cost?

  The cost of new uPVC windows varies significantly based on factors like size, style, and the number of windows. For a precise and no-obligation quote, we recommend contacting our Belfast team to schedule a free, no-pressure consultation. This ensures we can provide a price tailored to your exact needs.

• What is the lifespan of uPVC windows?

  Our high-quality uPVC windows are built to last for decades. With proper care and maintenance, you can expect them to have a lifespan of 20 years or more.

• What’s the difference between double and triple glazing?

  While both improve insulation, triple glazing provides an extra layer of glass for superior thermal efficiency. Double glazing is ideal for most homes, offering an excellent balance of cost and performance.

• Can I paint uPVC windows?

  While technically possible, painting uPVC windows is generally not recommended. The frames can expand and contract with temperature changes, which may cause paint to flake, fade, or peel over time. It can also void your manufacturer's warranty.

• How secure are your uPVC windows?

  All of our uPVC windows are designed with security as a top priority. They feature multi-point locking systems, internally beaded glass, and robust frames reinforced with galvanised steel to provide exceptional security against intruders.
