Senator’s Vertical Sliding Sash window provides a truly long-term, cost-effective solution for period style properties. Designed by Senator Windows to provide all the benefits that can be derived from modern high-performance materials, the advanced technology works in harmony with traditional design to provide extra comfort and practical features for modern living without compromising character or appearance. All Senator Senergy + Vertical Sliding Sash Windows incorporate energy-efficient 24mm double glazed units with a window U value of 1.5 and are “A” rated as standard to help save you money on your heating bills. The PVC window frames provide optimum strength, superior thermal properties and excellent weathering performance and will retain their pristine appearance year after year. Suitable for commercial or domestic buildings, the structural strength of our Vertical Sliding Sash Windows is enhanced through the use of steel or aluminium reinforcement with all fixings and hardware secured to the reinforcement. There’s also an interlock for the top sash, which increases the rigidity of larger windows.

Customer in Navan
Just a quick note to thank you and all at Senator for a fantastic job on my front door. I am absolutely delighted with it and my dealings with at all of staff guys were brilliant all the way through the process.Thanks again for everything and for accommodating the installation on the Saturday of a Bank Holiday week-end. I really appreciate it. 
Customer in Kerry
Just wanted to thank you for your attention to detail, customer service and courtesy. The lads were brilliant. They have their craft down to a fine art. Ireland would be a thriving country if we had at least 20% of a work force like them. So wish that I could have done all the windows now that I see them in.  Once again thank you very much for everything.
Customer in Cork
Excellent yet again, have used Senator four times and have been very impressed each time. The fitters left no mess and a beautiful finish, a quick lick of paint a week later and all done. No problem recommending Senator, and have already done so! Thanks again.
Customer in Wexford
Heating costs have reduced by at least 50% since we installed Senator Windows. All of my friends and neighbours have remarked “oh have you built a new house, as it looks completely different with the new windows and door!” The new window design also improves safety in our home in the event of a fire, which most people don’t even think about. The whole process from fitting to after sales service was superb.
Customer in Dundalk
Absolutely first class which includes the personnel, the quality of the product, the workmanship. I would have no hesitation in recommending your company to anyone. Well done and please pass my thanks to the gentlemen who installed the windows – as I did not get the chance to thank them personally.
Customer in Dublin
