HiMark Starmark Windows Reviews
The Okna Starmark window uses a composite frame that is somewhat thick, but does offer nice clean sightlines. The Starmark also offers excellent performance numbers and will offer U-factor and air infiltration that is roughly equivalent to the HiMark 800 Series. The Starmark is considered one of the top composite windows on the market, if not the flat out best. It isn't cheap, but it does offer good value for the money.
HiMark does not mention Starmark windows on their website, meaning that they don't carry this window under the HiMark brand name. Consumers who are interested in this premium composite window should be able to order it through their HiMark dealer or through an Okna dealer in your area. The Okna Starmark window generally gets excellent reviews from contractors and consumers alike.
