Product Information

It should come as no surprise that sliding patio doors can be a major source of heat loss in a home. Check the track for small stones and other obstructions, and run a vacuum cleaner along the bottom of the track to pick up all of those stray dust particles. Most people refer to this strategy as old school, but many of us will agree that it is still effective.

Clean the surfaces: Wipe down the areas where you’ll be applying weather-stripping to ensure a clean and dry surface. Building regulations state that installing a new door requires approval from the relevant buildings control body, and new external doors now generally contain integrated insulation to reduce heat loss and comply with regulations.You can remedy this by investing in double-glazed doors, which keep the condensation from forming on the outside. Thoroughly inspect your patio door for any gaps, cracks, or areas where air might be seeping through.

Patio doors are an ideal doorway since they allow in the morning light, creating a more open atmosphere until temperatures drop. Insulated doors help you make your home more environmentally friendly by decreasing your energy consumption. This and other small debris particles fall into the tracks throughout the year, causing your sliding door to get stuck. As the fall season fades and the winter season approaches, you begin to worry about how to keep your family warm, and knowing how to insulate patio doors is one way to do so.

If the door is a sliding or bi-fold door, then it might have been unseated from its rail, which will cause the gaps around the edges to grow. I used to clean mine every week until I was shocked with the amount of debris it was packing after a week and decided to give it special cleaning every three days. When looking for a new door, you’ll want to find one that has double glass panes, and seals heat inside during the winter. As secondary glazing is more specialised than double glazing, there isn’t currently a central body that certifies these installations.
