Energy Performance
uPVC Windows and Your BER Rating
In Ireland, a BER (Building Energy Rating) is the standard used to measure the thermal efficiency of your home. When evaluating windows and doors, the BER rating is based on the U-value (thermal transmittance) and the G-value (solar gain). Energy efficient windows are a big part of it and upgrading to Senator’s uPVC windows can make a meaningful improvement. Upgrading from single glazing or older double glazing to modern high-performance double or triple glazed windows is a smart, long-term investment.

Frequently Asked Questions
uPVC Windows - Your Questions Answered
Have questions about our windows? You’re in the right place. Below you’ll find answers to some of the most common queries we get from homeowners—from product options and energy efficiency to installation and budgeting. If you need more help, our team is always happy to assist.
What does uPVC mean in windows?
uPVC stands for unplasticised polyvinyl chloride. Unlike regular PVC, it has not been softened with plasticisers, making it rigid, strong, and highly durable – ideal for window and door frames. It is weather-resistant, low-maintenance, and an excellent thermal insulator.
What's the difference between double glazing and uPVC?
Double glazing refers to the glass unit – two panes separated by a gas-filled cavity. uPVC refers to the frame material the glass sits in. A uPVC window typically comes with double (or triple) glazing as standard, combining a thermally efficient frame with an energy-efficient glass unit.
Which is better - PVC or uPVC?
uPVC is better for windows. The ‘u’ stands for unplasticised – meaning it is rigid and hard-wearing rather than flexible. uPVC is stronger, more durable, and more thermally efficient than standard PVC, which is why it is the industry standard for window and door frames across Ireland and Europe.
What are common uPVC window problems?
Common issues with outdated windows and doors include condensation between panes (a failed sealed unit), stiff handles (worn mechanisms), draughts (perished seals), and discolouration on very old frames. High-quality Senator uPVC windows are designed to minimise these issues, with robust seals, multi-point locking, and lead-free materials throughout.
What is the lifespan of a uPVC window?
What is the average cost of a uPVC window in Ireland?
Cost varies by size, style, glazing specification, and installation requirements. Senator offers a free, no-obligation consultation and quote through your nearest showroom.
Is it worth replacing 20–25 year old double-glazed windows?
Yes, in most cases. Modern “A” rated uPVC windows offer far superior U-values compared to units from 20 years ago – reducing heat loss, lowering energy bills, and improving comfort significantly. SEAI grants of up to €4,000 are available for windows to help offset the cost for eligible homeowners.
Which is cheaper - aluminium or uPVC windows?
uPVC windows are generally the more affordable option. For most homes, uPVC offers excellent value: great thermal performance, outstanding durability, and very low maintenance.
Is it cheaper to replace all windows at once?
Yes, typically. Replacing all windows in one project reduces labour, and installation costs compared to piecemeal replacement.
Which window type is best for an Irish home?
uPVC casement windows are the most popular choice for Irish homes – excellent thermal performance, low maintenance, security, and value. However, what is deemed the “best” will depend on what you want to achieve from your project. Visit your nearest showroom for tailored advice based on your home, style, and budget.
Are double-glazed windows better now than 20 years ago?
Significantly so. Modern units use low-emissivity coatings, warm-edge spacer bars, and argon gas fills, achieving U-values well below what was possible 20 years ago. Upgrading is a worthwhile investment in comfort and energy savings – especially with SEAI grant support now available.
What is the cheapest time of year to replace windows?
The most important factor when buying windows is choosing a quality manufacturer and installer. Senator operates year-round and SEAI grants are available regardless of season – there is rarely a good reason to delay an upgrade.
