How to reduce heat loss in houses with large glass panels
Get some useful tips here
If your home is losing heat, it will have negative consequences for your electricity bills, standard of living and the environment. If you want to use the least amount of energy possible to heat your home, it is important that heat loss in the house is kept to a minimum.
Installing better insulation and reducing heat loss from windows will reduce the energy demand considerably. You can also save both electricity and the environment by replacing old windows and doors.
Windows in aluminium are sustainable
Today, many people like to give their homes new qualities by installing large windows and glass panels to let in more daylight and create visual openness. This does not need to be at the expense of heat preservation and energy efficiency.
We live in an exposed country. You should therefore choose products that have been adapted to the Nordic climate. You need doors and glass panels that have good thermal insulation properties, and are equipped to withstand pressure from the elements. When you choose glass panels and sliding doors in aluminium, you maintain both the aesthetic and thermal insulation properties. Sapa Selection can supply glass facade solutions with passive house certification. Without draughts from the windows, you can lower the temperature in the room, which contributes to a better indoor climate and lower energy costs.
To limit heat loss, you must install doors and windows that are well insulated. The U-value is a measure of how well a window or glass door provides insulation. Technically speaking, the U-value is described as how much heat passes through a one square metre window or door at a temperature difference of one degree Celsius. The lower the U-value, the better the thermal insulation. The U-value refers not only to the properties of the glass, but also the total heat loss from the sill, frame and glass.
Choosing an aluminium frame with a broken thermal bridge and triple glazing will give you a good starting point for a low U-value. If you also add a highly insulating sill, the airtightness will be even better. Sapa Selection insulators and seals limit heat loss in an optimal way and provide high air and water tightness. This means low energy consumption and excellent comfort.
Heat loss in glass doors and windows refers not only to the product’s inherent properties, but also to how they are installed. An outer wall has an external and an internal side. We find a zero point inside the wall, which shows the transition from a warm to a cold temperature. It is important that the windows are installed in the warm zone, where the temperature is above zero. If the window is installed too far out in the facade, it can end up in the cold zone, so the thermal insulating properties are not fully exploited.
