Welcome To


The Thermawood Retrofit Double Glazing System creates a unique patented dry glazing system for timber windows and doors for your home.

The patented Thermawood Double Glazing system is designed to drain any moisture from the rebate around your double glazing to create longevity of your double glazing and peace of mind that your double glazing will last a long time. Double glazing involves adding an insulated glass unit with the option of argon gas between the two-glass panes, providing excellent protection for any home or commercial property. The systems are designed to fit any wooden joinery and can be used in many ways that suit both your property and lifestyle.

The goal of Thermawood is to keep your home comfortable, especially during the colder & hotter seasons & to reduce noise. Our Thermawood Retrofit Double Glazing lets in as much sunlight as single glazing systems yet can remain substantially warmer and cooler because of its excellent heat retention qualities. With Thermawood’s Double Glazing, you have a valuable addition to your property that helps you save money on monthly energy costs. If you need thermal or acoustic solutions for your home, talk to our team of double glazing installers today and request a quote.

What Is

Double Glazing

Single glazed windows only use one glass panel. With double glazing, you’ll need two panels of glass hermetically sealed to create an insulated glass unit (IGU). The two panels are separated by a spacer, between 6mm to 18mm, and can then filled with Argon Gas for better insulation. This technology helps dramatically increase the insulating power of a window, preserving cool temperatures in the summer and reducing heat loss in the winter.

The Thermawood Retrofit Double Glazing System is the only system that ensures quality without altering the original appearance and character of your property. Designed for timber joinery, the Thermawood Retrofit system is ideal for your home’s windows and doors.

To keep you comfortable in all weather conditions, the Retrofit Double Glazing System fights both heat loss and gain. The patented system also encourages optimal drainage, minimises glare, decreases fading, greatly reduces external noise and enhances overall safety and security.
