Specifications And Features: Circle Tops/Elliptical Heads

  1. Frame – All parts are 6/4 kiln dried western pine which are treated with a water repellent preservative and can be painted or stained as desired to complement the individual interior design and style. The basic jamb is a full 4 9/16′, however, any desired wall thickness can be accommodated without the use of extension jambs thereby leaving no unsightly seams. All Trimline circle units are manufactured with full jambs.
  2. Cladding – The frame cladding is designed so that each TrimLine decorative window can be installed individually or mulled to other TrimLine single or multi-lite casement, awning or double hung window units. The insulating qualities of an interior wooden jamb provide a positive thermal break while being fitted to a low maintenance extruded aluminum exterior frame in a choice of four colors.
  3. Flashing – The aluminum exterior frame is designed with a continuous flange around the entire unit perimeter forming a combination mounting fin and window flashing.
  4. Glazing – All units are direct-set glazed with insulating glass up to 1 ¼” in overall thickness. All insulating glass is manufactured using SuperSpacer® which has the lowest thermal conductivity of any edge-seal on the market today increasing the overall R-value by up to 30%. Low E, various tinted and other specialty glass as well as tempered or safety glass is also available. All units are glazed from the inside with decorative wood stops for ease in reglazing.
  5. Interior casing – Interior wood casing in 2 ¼” or 3 ½” colonial or ranch styles are available in pine or solid natural oak and is ready for painting or staining.
