SOFTLINE 68 / 78 / 88 Entry Door

SOFTLINE is a three-layer laminated wood entry door system available in three build depths (68, 78, and 88 mm) and two wood species (European pine and meranti tropical hardwood). The system uses the same construction philosophy as the SOFTLINE wood window line, with structural laminated timber slab and frame plus entry door hardware including 3-point multi-hook locking, 3 roller hinges, and aluminum thermal-break threshold.

The three-layer laminated construction bonds three layers of solid wood with the grain rotated between layers. The opposing grain directions cancel each other under seasonal humidity variation, preventing the warp, twist, and binding that affects single-layer solid wood entry doors over time. This is the European standard construction method for premium wood entry doors and is the reason SOFTLINE doors maintain operation over decades where single-layer wood entry doors require periodic planing and rehanging.

Thermal performance scales with build depth. The 68 mm depth at Ud = 1.1 W/(m²K) suits residential applications where moderate thermal performance is acceptable. The 78 mm depth at Ud = 0.9 W/(m²K) is the standard premium residential entry door spec. The 88 mm depth at Ud = 0.85 W/(m²K) is the top thermal performance in the wood entry door category, comparable to premium thermal-break aluminum entry doors through solid timber construction.

The seal configuration uses 3 EPDM gaskets, matching the premium PVC entry door spec (IGLO ENERGY and IGLO EDGE doors). Hardware includes 3-point multi-hook locking engaged from the deadbolt, 3 roller hinges sized for the laminated timber slab weight, aluminum handle, and mounting cylinder. Smart lock and electronic strike upgrades are available across the three depths.

The aluminum threshold with thermal break strip is standard, the primary reason SOFTLINE wood entry doors do not develop the bottom-rail moisture issues common on traditional North American wood entry doors after 15 to 20 years of service.

Maintenance cycles for exterior wood entry doors require annual visual inspection, cleaning every 12 to 18 months, finish touch-up every 5 to 8 years on south and west elevations, and full refinish every 12 to 15 years. The aluminum threshold, factory finish quality, and three-layer construction extend the cycle. Doors installed under porches and overhangs require significantly less maintenance than doors exposed directly to weather.

Application range is residential entry doors in traditional and historic architectural styles across the Northeast US climate envelope — particularly historic districts in northern NJ, Westchester, Bucks County, and Fairfield County, traditional and Colonial Revival custom residential, and premium custom builds where the front entry is the statement piece.
