    Why Use QUAD Max?

    There are many reasons why window and door sealing should never be overlooked. When doors and windows are properly sealed, heat and cold are kept inside during winter and summer months. This in turn helps to increase energy efficiency. On the other hand, if sealing is not done correctly, this creates a risk of drafts, and ultimately makes it more difficult for heating and cooling systems to regulate temperature. Taking the right steps to protect your foundation from moisture will also prevent the growth of fungus and keep bugs away.

    LePage offers an arsenal of adhesives, caulks, and outdoor construction sealants for the true professional. With over 80 colors to help match your interior, LePage QUAD MAX gives you over 4,600 color matches to your doors, windows, and sidings.
