RAINSCREENS
Founded on the proven principals of BŌK Modern’s line of products, EnFold Façade’s patented Rainscreen system is unique to the façade market.
Our Rainscreen is a non-flammable, solid sheet metal, single skin panel – not a composite. Panels can be solid, bas-relief, or custom laser cut to your specifications in aluminum or weathering steel, and custom formed to an infinite variety of 3-dimensional configurations. Finishes include Kynar, powder coating, anodized aluminum, and weathered/oxidized surface (Cor-ten) steel.

DETAIL
WHY BŌK MODERN RAINSCREENS?
BŌK Modern’s patented Rainscreen system is like no other on the market. Our Rainscreen is a non-flammable, solid aluminum, single skin panel; not a composite. The folded crisp edge result in a super flat face.
It can be solid, bas-relief, or custom laser cut to your specifictions in aluminum or weathering steel. We can also custom form to a large variety of 3-dimensional shapes. We also offer a 12 and 14 gauge weathering steel option as well as stainless steel in a variety of surface treatments.
Standard finishes on aluminum include Kynar, in unlimited colors, powder coating and anodizing. We offer specialty coatings as well. Our patented tab and slot system has an integrated spacing feature to space the panels without using shims to ensure a quick and easy install.
When installed directly over a suitable substrate (i.e. plywood), our unitized panel system generally requires no additional furring or other secondary support members. Reducing labor costs in the field means a higher quality of panel for your project budget. When installed over insulation or other such substrate, our panels are attached directly to standard ‘z’s’ or hat channels.
All of our panels are precision manufactured to your specifications for your specific job. All of your panels are modeled 3-dimensionally in Solidworks and fitted before fabrication. All panels are crated in solid wood crates and each panel has laser cut part numbers to insure quick identification during install. BŌK provides in-house engineering for our panels with loads for your Engineer of Record to provide the appropriate backing structure.
THERMAL EXPANSION
THERMAL EXPANSION
BŌK Modern offers a premium product that architect's love. We pride ourselves on our flat panels. How we can achieve this is by accommodating for thermal expansion in the panels themselves and having a complete understanding of where the expansion is going to take place.
Aluminum and steel expand at a consistent rate relative to the material. The finish color also influences the expansion. Darker colors absorb more heat and expand at a faster rate. Some expansion is inevitable when the sun is at certain angles. Occasionally this minimal expansion is made more dramatic by critical light. In most cases 1/4" typical gap is sufficient.
Thermal Expansion Equations
- Aluminum: 13*F*10^-6
- Corten: 8.3*F*10^-6
CRITICAL LIGHT
Critical light is a phenomenon where flat surfaces that are very close to perfectly flat appear to have large distortions due to the angle at which light hits the surface. Typically, dramatic lighting of 15 degrees or less will create exaggerated visual distortion. This effect is magnified in photograph
