The Indoors Rushmore Opaque Glazed Pre-Finished Oak Door allows light to flow through your home space. The opaque glass delivers complete privacy with optimum light transference. The glass in this interior door is known as ‘lamsafe’ which has a thin sheet of P.V.C sandwiched between two layers of toughened glass. This makes the glass 5 times stronger than ordinary glass. This durable door is fine sanded and pre-finished with 3 coats of hard wearing polyurethane lacquer, for a superb satin finish. Guaranteed not to shrink, warp or twist.
