For enhanced thermic & auditory qualities

South West property owners looking to enhance their single, secondary or double glazing are becoming increasingly interested in triple glazed units. Not only do they reduce a buildings energy consumption further, they can have additional acoustic qualities to aid noise reduction.

With energy efficiency firmly in mind, Seal-Lite can offer triple glazed units with the highest achievable score. As well as reducing energy bills, our triple-glazing system also acts as an enhanced barrier to external noise. Noise pollution can also impact on the value of a property, which is why our customers consider triple glazing or acoustic laminate options.

Glazing to suit all window styles

Triple glazed units provide South West homeowners with unparalleled energy confinement and noise reducing qualities, that double and single glazing simply cannot compete with. In comparison to double glazing, triple glazed windows can provide an additional 15% energy saving each year.

Made to measure, triple glazing will most certainly keep you warm and cosy throughout the harsh winter months. Vastly improving health and well-being right across the board, high quality triple glazing generally lasts well over 20 years so the investment is definitely worth it; as long as it's properly maintained of course.

    "An excellent service all round"

    An excellent service all round. Very friendly and took time to ensure the windows were exactly as I wanted. The windows themselves are well made and have completely transformed my house.

    "Thoroughly recommend Seal-lite"

    We had Seal-lite install full new double glazing including bi-fold doors a little while ago, excellent products and service. Their after sales service by Simon is very, very good indeed. Thoroughly recommend Seal-lite.

    "Excellent service from start to finish"

    An excellent job done by Paul and his team. Transforming the front of our house with Georgian bar style windows and a fantastic new bay window. Finished off by a new door. Highly recommended excellent service from start to finish.

    "Very patient and understanding"

    I would absolutely recommend Seal-Lite Ltd. They have been so helpful helping me to match my new aluminium windows to the existing house. They have also been very patient and understanding with me having to delay installation for several months due to problems with my builder. Kevin fitted the windows very carefully and did an excellent job. A couple of minor things were no problem and resolved quickly to my full satisfaction. I would like to thank Paul and Pete and the team for being so so helpful. A pleasure to do business with this company – I wish all companies were like this.
