Best Practice Guidance
Helpful knowledge and advice from EJOT experts
What are fixed and sliding points, and why are they important in façade assembly? Why is unrestrained fastening specified by guidelines and approvals?
Facades are exposed to constant fluctuations in temperature. The materials used normally have different coefficients of expansion. It is therefore important to constructively allow for the possibility of thermal changes in length.
What drilling method should be used for different masonry types?
For each type of stone, a drilling process is specified by the approval. This is of vital importance to achieve the pull-out load capacity. In most perforated bricks and in aerated concrete, the drill holes must be created in a rotary drilling process.
How does a non-load-bearing system differ from a load-bearing system? What is single fastening vs multiple fastening?
A non-load-bearing system is a construction which does not contribute to the stability of the building. If the embedment fails, the fastened construction falls down, but the building remains intact.
When are injection systems used instead of through-bolts? What products does EJOT offer for injection anchoring?
Injection systems are used in particular for rainscreen facades, if another anchor no longer achieves the required loads. They allow maximum loads even with thin-walled perforated bricks.
What is a rainscreen facade? How does it protect buildings?
A multi-shell exterior wall construction is referred to as a rainscreen facades. The non-load-bearing facade cladding is attached to the load-bearing wall level at a distance.
How do you calculate the grip length of a plastic façade anchor? What is the difference between push-through and pre-positioned installation?
Based on the details of the total length and the details about the installation depth of the anchor in the substrate, the so-called grip length can be easily calculated...
What is the CROSSFIX® substructure system, and how does it improve performance?
CROSSFIX® by EJOT is a substructure system for the rainscreen facade. The console is made of stainless steel (A4).
Rainscreen & Façade Most Common FAQs
In this article, 15 of the most common FAQs about all things Rainscreen & Façade have been answered by EJOT UK's experts.
How should through bolts be installed correctly? How do through bolts perform under load, and what design considerations apply?
Through bolts achieve their load-bearing capacity even in cracked concrete or in the case of seismic requirements through their aggressive expansion and the ability to expand afterwards.
What happens if a fastening point fails? What options exist when multiple fastenings aren't feasible?
Understand the consequences if a fastening anchor point fails in both a single or multiple use application...
Which standards and approvals apply to rainscreen façade systems? How does the ETA affect fastener selection and façade safety?
When it comes to the embedment of facade constructions, safety is of prime importance. The use of all EJOT embedment, connector and fastening elements is specified by construction law in an ETA (European Technical Assessment).
How is a rainscreen façade constructed? What are the design advantages of a rainscreen façade?
A rainscreen facade is made up of several layers. The wall brackets are attached to the first layer, the base material.
How do you determine required anchor length and installation depth? When should anchors be used in a single or grouped configuration?
The EJOT plastic anchor, which is approved in Europe, is therefore always sold as a unit. To determine the necessary anchor length, it is important to know the thickness of the attachment to be fastened and the thickness of the non-load-bearing layer.
What are the benefits of guided embedment connections? How does adhesive bonding differ from other embedment methods?
Undercut anchors for concrete or injection systems for perforated bricks generate comparably high tensile capacity due to the guided joint connection with the substrate.
What are the main embedment mechanisms for rainscreen facades? How does a frictional embedment (expansion) connection work?
There are three different embedment mechanisms that form the basis for attaching a rainscreen facade: by frictional connection through expansion, guided connection through undercuts or adhesive bond through composite.
What is unrestrained fastening and why is it necessary? What features does the EJOT® LT system offer for facade fastening?
The necessity of an unrestrained fastening is not only specified by design guidelines, approvals and assembly guidelines, but is important for the later appearance of the façade.
