Entuitive – Building Envelope

The building envelope services team at Entuitive specializes in the complete enclosure of new and existing buildings, including cladding, glazing, roofing and waterproofing.

Our goal is to maximize the performance of the building skin — making sure it looks better, lasts longer, and performs as a complete and efficient environmental separator.

We understand a wide range of materials and systems, their compatibility and how they perform over time. And we are continually evaluating new materials and ideas. By collaborating with architects contractors’ suppliers and system designers, the Entuitive team of specialists balances many criteria — aesthetic, functional, technical, performance and durability — against issues such as cost, availability, scheduling and programming requirements so we can advise on the best solutions.

Within our team, we have a breadth of experience and knowledge, and we ensure that sound building science theory and building envelope expertise are applied to every project, large and small. Also, in support of our solutions we apply computer simulations to test our ideas during design, and sophisticated field testing to verify performance during and after construction. We have the tools and experience to ensure that your building performance is optimized.
