The Senator uPVC Vertical Sliding Sash Window can be fitted with Angel Ventlock® restrictors, if specified. The restrictor allows you to open the window wide enough for ventilation but not wide enough to compromise security or child safety. In case of emergency, restrictors can be released as a means of escape.

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 guarantees. If you need more help, our team is always happy to assist.
The cost of replacing your windows depends on a few key details—like size, material, style, glazing, and any extras you choose. Since every window is made to measure, just let us know what you have in mind, and we’ll be happy to provide a free, no-obligation quotation tailored to your needs.
While it can be more cost-effective to replace all your windows at once, some homeowners choose to do it in two stages—starting with the front and coming back to complete the rest later. It really comes down to what works best for you, your home, and your budget. We’re here to help you find the right approach.
Both materials are strong, energy efficient, and stylish—but there are a few differences worth considering before you make your final choice. Often, it comes down to personal preference, though in some cases one option may suit your home better than the other. If you’re not sure which is right for you, visit your local Senator showroom where you will see both materials on display and your Senator Dealer will be happy to help you decide.
There are some clear signs it might be time to replace your windows—like draughts, rising heating bills, or visible wear and tear. Upgrading your windows is a smart investment that not only makes your home more comfortable, but can also improve your BER rating and help lower your energy costs in the long run.
How often you’ll need to replace your windows depends on their quality, type, and the conditions they face over time. Most people will only replace their windows once or twice in a lifetime—so it’s worth having trusted experts by your side to help you get it right.
To learn more about available grants for energy-efficient windows in Ireland, visit the Sustainable Energy Authority of Ireland (SEAI) and your local authority websites. You’ll find up-to-date information on current supports to help make your home warmer, more efficient, and comfortable all year round.
