Building Envelope Contractor Kelowna


A building envelope is the complete exterior system separating the conditioned interior of a building from outside weather. It includes far more than siding. Exterior cladding, weather-resistive barriers, air barriers, rainscreen cavities, flashing, windows and doors, penetrations, soffit, fascia, sealants and drainage details all need to work together to manage water, air and moisture.


Diamond Exteriors provides building-envelope work as part of exterior renovations, siding replacement, cladding projects, new construction and multi-family exterior scopes throughout Kelowna and the Central Okanagan. Our exterior work is approached as a complete system rather than simply installing a new finish over an existing wall.


When older siding or cladding is removed, important parts of the building envelope become accessible. This can reveal the condition of the sheathing, existing housewrap or weather-resistive barrier, window flashings, penetrations, wall transitions and drainage details. Reviewing these components before installing the new exterior allows deficiencies to be addressed while the wall is open.


Diamond Exteriors works with building-envelope materials and systems including DuPont Tyvek, Henry Blueskin, weather-resistive barriers, rainscreen assemblies, flashings, tapes, sealants and exterior cladding attachment systems. These components can be integrated behind James Hardie siding, fibre-cement products, metal siding, architectural cladding, panel systems, wood and wood-look siding, stucco, masonry and other exterior finishes.


Rainscreen and water-management details are particularly important in exterior wall assemblies. The objective is not to assume that the outer cladding will stop every drop of water. A properly planned wall assembly provides additional layers behind the finished exterior to control drainage and protect the building structure.


Diamond Exteriors provides building-envelope upgrades for residential renovations, siding replacement projects, custom homes, builders, developers, strata properties and multi-family buildings. Related services include exterior inspections, cladding replacement, soffit and fascia, gutters, custom sheet-metal flashing and complete exterior renovation scopes.


Our service area includes Kelowna, West Kelowna, Lake Country, Peachland, Summerland, Vernon and surrounding Okanagan communities.


If an exterior project involves more than simply changing the visible siding, Diamond Exteriors can assess and coordinate the underlying building-envelope components so the finished cladding and the systems behind it function together as one complete exterior assembly.
