Building science

Follow every control layer around the building.

A good enclosure manages water, air, heat, and vapor while supporting intentional fresh air and practical services.

SIP wall panels meeting at several carefully fitted intersections

Four control layers

The building works when the layers connect.

A strong panel field cannot compensate for weak transitions. Continuity has to survive the full path around the enclosure.

Water

Drain bulk water away from the site and shed rain through roofs, cladding, flashing, openings, and drainage planes.

Air

Connect the air control layer across panels, joints, roofs, foundations, windows, doors, and penetrations.

Heat

Maintain insulation continuity through the main assemblies and study unavoidable thermal bridges.

Vapor

Select assemblies and materials that fit the climate, interior conditions, drying potential, and complete wall or roof design.

The main wall field

Continuity is easier to understand when the material is visible.

SIPs can reduce repeated framing through the main panel area. The connection strategy still determines whether air, heat, water, and loads move through the enclosure as intended.

SIP wall panels meeting at interior and exterior wall intersections
Connections determine continuity.The main panel field can be highly insulated, while intersections, splines, openings, roofs, foundations, and penetrations still require deliberate detailing.

Critical transitions

Detail the places where systems meet.

These are project specific design and inspection priorities.

Foundation to wall

Coordinate sill conditions, capillary control, air sealing, water management, fastening, and tolerances.

Wall to roof

Resolve structure, splines, seals, overhangs, ventilation strategy, and water shedding at the transition.

Windows and doors

Connect flashing, drainage, insulation, air control, structure, and installation sequence around every opening.

Penetrations

Plan services and equipment so each opening can be supported, sealed, protected, and inspected.

Fresh air and services

A tight building needs intentional systems.

Mechanical ventilation, filtration, humidity control, exhaust, pressure relationships, and equipment sizing belong in the design. They are not optional corrections after the enclosure is complete.

Electrical chases, plumbing routes, ducts, equipment, and access also need early coordination so field changes do not compromise the panel or its control layers.

Start a project

Bring building science into the first design meeting.

Legacy can help identify the enclosure questions that need answers before engineering and manufacturing.
