Subsills

Sill thickness and depth should complement a casing option and window style. If a standard wood subsill isn't the right match for your project, choose from hundreds of wood subsill options.

Please note that due to the variety of possible combinations of casings and subsill options, special dimensional considerations for different installation methods are required. Please contact your local Marvin retailer when specifying casing and subsill combinations.
