For a budget-friendly glazing alternative

South West property owners looking to upgrade their single glazed units are becoming increasingly interested in secondary glazing. Not only do they help to reduce a buildings energy consumption, they also provide an additional barrier against external sound. This is a valuable option especially in conservation areas where full replacement windows are not permitted.

With energy efficiency firmly in mind, Seal-Lite are able to offer secondary glazing with the highest achievable score. As well as having the potential to reduce energy bills, our secondary glazing system also reduces draughts whilst preserving the original windows structure too.

Glazing to suit all window styles

Secondary glazed window panes provide South West homeowners with improved energy confinement and noise reducing qualities, that single glazing simply cannot compete with.

Made to measure, secondary glazing is sure to keep you warmer and cosier throughout the harsh winter months, in comparison to single glazing. Able to assist in improving health and well-being in the home, high quality secondary glazing is an ideal option for listed buildings where double or triple glazing may be restricted.

Made to measure, our secondary glazed units are hard wearing and deliver an effective extra layer of security.

    "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.
