How to insulate windows inexpensively: a few useful tips

SSPDaily has prepared tips to help you optimally insulate your windows. Learn about affordable and effective ways to insulate your windows.

The right insulation materials

For budget-friendly window insulation, you should use economical materials such as bubble wrap. Bubble wrap is easily attached to windows with water and effectively prevents heat loss and drafts. This provides affordable thermal insulation and an aesthetic effect.

Sealing gaps and cracks

Carefully inspect the windows for holes and seal them. Seal small gaps with sealing tape or caulking. For large holes, use expanding foam insulation.

Secondary insulation of windows

One option is to stick a thermal insulation film on the window with double-sided tape. This transparent film becomes airtight when heated with a hairdryer.

Use of window blinds and curtains

During the cold season, closing blinds and curtains at night helps trap warm air and reduce heat loss. Warm or blackout curtains provide an additional layer of insulation and prevent drafts. Made of insulating fabrics such as thermal lining or thick polyester, they are effective in improving energy efficiency.
