Weather Lock Snap On Windows were invented in 1983 by Robert W. Orth to give homeowners an option between the high cost of total window replacement and the yearly expense of shrink wrap plastic.

In 25 years of business, Weather Lock has established a national dealer network that has installed in excess of half a million Weather Lock Snap On Windows.  The product uses multi-patented technology which includes the interlocking, air-tight, snap on, design and optional interchangeable window screen.

Reusable Weather Lock is going green by stopping up to 81% of total window heat loss saving precious energy.  It is truly the only inexpensive solution to heat loss through the windows.

Why Weatherlock?

• Cost a fraction of new window replacement (usually 1/4 the cost or less)
• More air tight and energy efficient to add snap ons to existing windows than total window replacement
• Work equally well to greatly reduce both heat and air conditioning loss through windows
