The Thermal Benefits of Secondary Double Glazing

Secondary glazing increases the thermal efficiency of your existing windows, eliminating cold spots and draughts and helping to retain heat. It is for this reason that secondary glazing is becoming an increasingly popular choice amongst homeowners in place of costly triple glazing.

Secondary double glazing refers to the single pane of glass that is installed inside your home on to an existing window unit. The timber subframe, aluminium frame and thick glass work together to create a unique secondary glazing unit that actively retains heat. These units operate as part of your window to eliminate any chances of damage, intrusion and heat loss, improving their thermal efficiency drastically.

They are perfect for listed buildings and those looking to increase the thermal efficiency of their home in conservation areas. Our secondary glazing units will increase the thermal efficiency of your home while reducing noise intrusion by up to 80%.

Keeping Warm with Secondary Double Glazing

The main reason why people choose secondary double glazing is due to the high level of comfort that it brings to your home. With our range of options, you can choose the perfect one to make sure your home is warm and comfortable.

Secondary glazing is soaring in popularity because of the many advantages it provides. Energy efficiency is one of the most desirable features of any home, improving the look and feel of your living space all year round.

Save Money with Us

Our units keep your home warmer for longer, minimising heat loss by as much as 65%. This means you won’t need to turn up the thermostat, which will save you money on your heating bills.

Energy efficient secondary glazing is one of the finest home improvements you can choose for your property, saving you money in the long term while preserving your existing authentic window style.

Lower U-Values

U-value scores indicate how effective a material is at retaining heat, which means the lower the score, the better the window is at insulating your home. Each unit we offer comes with a 0.8W/m2K u-value, making it perfect at insulating your home.

Homeowners and businesses alike are increasingly keen to invest in low U-value home improvements, so our energy efficient secondary glazing is a popular choice.

Eliminating Draughts

Draughts can make rooms cold and uncomfortable, rendering them unusable for many homeowners.

Available in a range of 4mm, 6mm or 8mm in size, our secondary double glazing is perfect for eliminating unwanted draughts and cold spots.

We also utilise Low-E glass, which uses a specific coating that reflects heat back inside your home, improving the performance of your windows.

Our Recommendation

To ensure you are getting the most out of our glazing unit, we recommend fitting your second unit with an air cavity no deeper than 80mm.

At Granada, we can manufacture our secondary double glazing units to feature a timber subframe. This ensures your home has an excellent thermal barrier, whilst stopping the aluminium frame in the unit from cooling too much.
