What people are saying about Window Seal Systems!

"Previously we had a lot of complaints about noise coming from the surrounding streets but since the installation of the Wind-Do Seal Secondary Glazing System we have not received one complaint about noise from our guests. Excellent result!"

Jimmy Kealy, Hotel Manager, Jurys Inn, Parnell Street, Dublin 1


"This company stood out for both quality and price! We are absolutely delighted with our decision to invest - we have saved already a fill of oil after just 3 months; not to mention the drop in noise level from passing traffic!" 

McCormack Solicitors, 4 McElwain Terrace, Newbridge, Co. Kildare

"We manage a number of apartments in Dublin city centre. We were having issues with street noise in several of the apartments that was causing on-going issue for our tenants. We had secondary glazing installed by Wind- Do Seal Systems and the difference has been dramatic. I was very surprised at the level of noise reduction achieved by the glazing. I would definitely recommend this company and its product"
