Sealing System Triple-fin perimeter weatherstripping in grooved retaining tracks
Glazing Capability Double or triple-pane IGU with warm-edge spacers & Argon fill
Sash Operation Dual tilt-in sashes on heavy-duty constant force balance cams
Finish Options Extruded solid white or Doublenature™ authentic architectural woodgrain
NFRC Authorized Dual Cam Action Locks Sloped Anodized Sub-Sill

NFRC Product Certification Authorization (CAR) Reports

Fully compliant with thermal transmission and solar heat gain ratings verified under independent lab inspection.

Single Hung & Single Sliding Heavy-Duty Glazing

Optimized for multi-unit developers needing structural simplicity, durability, and cost efficiency. The top sash remains permanently bonded to the master frame, reducing air leakage indices while supporting extra-heavy acoustic and insulated glass lites.

Design Rationale High lateral wind load resistance with minimal mechanical joints
Compound Chemistry Impact-modified PVC formulation with titanium dioxide UV barriers
Weather Sealing Continuous fin-seal barrier along bottom rail and interlocking meeting stile
Maintenance Access Tilt-release bottom sash for interior glass maintenance
Sizing Versatility Engineered in fractional increments for retrofit or new masonry builds
AAMA Rated Extrusions Heavy Glazing Pocket Factory Weep Baffles

NFRC Product Certification Authorization (CAR) Reports

Verified air leakage rates under ASTM E283 with high condensation resistance indexes.

Architectural Trim & Profiles

Integrated Brickmould & Casing Add-Ons

Engineered PVC exterior profiles allow contractors to preserve heritage architectural appearance without compromising maintenance-free longevity.

Brickmould profile 5916 with breakaway J-channel

BRICKMOULD 5916

1 3/16" with Optional Break-Away J-Channel

Replicates authentic wood molding contours while retaining the dimensional stability of cellular PVC. Features mechanical fastener flutes for structural attachment to subsills, an integrated breakaway J-channel for siding integration, and a white co-extruded perimeter seal that conceals fastener joints.

Facing Width 1 ½″ visible exterior profile
Casing Depth 1 3/16″ projection with 1 1/8″ frame overlap
Installation Available without nailing fin for direct masonry fit
Brickmould profile 5990 flat casing

BRICKMOULD 5990 FLAT

3 1/2" Exterior Flat Casing with Break-Away J-Channel

Engineered for transitional American architectural styles. Delivers a clean, linear 1″ × 3″ casing appearance with integrated 5-degree sloped sill drainage. Can be field-trimmed down to 2″ width along continuous reference guide grooves and flex-bent to curved arches up to a 24″ radius.

Profile Width 3 ½″ surface face (exceeds 3″ from frame exterior)
Sill Slope 5° outward pitch for moisture evacuation
Radius Capability Heat-formable down to 24″ architectural radius

Frequently Asked Questions

Our vinyl window lines undergo strict National Fenestration Rating Council (NFRC) testing and certification for U-Factor, Solar Heat Gain Coefficient (SHGC), and Air Infiltration. All extrusions conform to high-impact, UV-stabilized PVC compounding standards.

Yes. Our on-site Haverhill production plant operates precision CNC extrusion and fusion-welding lines capable of fabricating custom fractional dimensions, specialized jamb depths, and tailored brickmould casings for multi-family and commercial trade orders.

We provide a comprehensive commercial manufacturer warranty including a 20-year structural guarantee on PVC extrusions, a 10-year warranty on hermetically sealed thermal glass units, and a 10-year warranty on precision mechanical hardware.

Every window unit is wrapped with corner guards, protective surface film, and strapped into heavy-gauge vertical timber crates configured for container loading or flatbed transport, preventing racking and glass damage during transit.
