One of the ways to overcome these issues is to use an anchoring solution, when used in combination with a special tool, this allows the anchor to be installed into the insulation to the correct depth in a controlled manner.
The installation tool cuts the area around the anchor washer and the insulation material is automatically compressed under the washer when the anchor is screwed in. An insulating cap formed using the same type of insulation can then be inserted flush into the recess between the anchor washer and the facade surface, allowing for a homogenous installation surface to be achieved.
Understanding profile basics Equally important to the installation simplicity and long term performance of an EWI system are the profiles. Innovative detailing in their design can make a significant difference to the quality of the rendered finish, particularly at corners and around reveals such as windows and doors. Corner bead angles, for example, provide reinforcement to allow for the exact formation of 90° corners. They may feature a one-sided mesh overhang to achieve
an optimal overlap, as well as helping to prevent cracking. Other types of profiles serve specific purposes, such as drip edge profiles, which provide targeted water flow, and frame seal beads designed to create a permanent seal around windows and doors to prevent moisture ingress.
Accommodating external attachments
Innovative fixings also enable the integration of secure attachment points within the ETICS facade for elements that will need to be installed once fully rendered. Planned attachments can be integrated within the EWI system as it is built-up, providing these are considered at an early design stage, which will be needed for safety critical elements, such as the railings for balconies.
Other elements that may not have an exact position set at the outset, such as brackets for downpipes, mountings for air-conditioning units and exterior lighting, can be attached to a completed facade with ease.
