Is a Solarlux Wintergarden glass extension cold in winter and hot in summer?
)
A fully glazed Wintergarden home extension is the perfect way to create extra living space that's flooded with natural light, allows for panoramic views of your garden, and offers a smooth transition between the indoors and outside. But how does it fare as the seasons change? Does it get cold in winter and hot in summer?
Solarlux Wintergardens combine innovative thermal break technology and high performance glazing to remain comfortable for year-round use. The thermal break prevents heat loss in winter and reduces overheating in summer. Double or triple glazing significantly reduces heat loss and, in some cases, can help achieve Passive House standards. Our Wintergarden glass extensions can reach low Uw-values, reflecting an excellent combined performance of both glass and frame.
This means your Solarlux Wintergarden will perform just like any other room in your home. It will be so thermally efficient that you won't even need an internal or external door between it and your home - allowing for a fully open plan design if desired. And, while you can still add heating, ventilation and shading for extra comfort, the room itself remains warm and energy-efficient, regardless of the weather outside.
