Nothing beats a warm, cosy home - and now you no longer need to be one of the thousands of New Zealanders who suffer from a cold, hard to heat house in the winter. Penjerex window insulation means you can enjoy the comforts of a warmer home with the window film keeping the heat in and the cold out. With a warmer home you’ll reduce your energy consumption, resulting in savings on your winter power bills and less of an impact on the environment.

And you won’t just benefit from Penjerex in the colder months. Often houses that are cold and hard to heat in the winter are too hot in the summer. Penjerex window film insulates your house from the temperature outside, which means you’ll lose less warmth through your windows in the colder months, as well as have less heat entering your home when the hot sun is beating down in the summer months. This insulation solution is perfect for those with older homes, who want to keep the look and character of original windows, but are looking for an upgrade in comfort and an effective way to insulate single-glazed windows.

Penjerex is a brand you can trust - and we guarantee it. A 10 year product replacement warranty will give you confidence in the longevity and quality of the Penjerex window insulation.
