Window construction

Substructure for lift and slide systems

The trend towards ever larger lift-and-slide systems leads to correspondingly higher weights that have to be transferred to the substructure insulating profile.

The lift and slide substructure combines strength and excellent thermal insulation thanks to two load-bearing layers and an insulating core with a very low dead weight. Thanks to the two thick load-bearing layers on the inside and outside, screw connections can be made from above and below without any problems. The forces are thus easily transferred into the masonry.

Diversity

Dimensions

COMPACFOAM Substructure insulation profiles are not only available in the standard length of 2350mm, but also in any desired length up to 6m.

Coating

On request, the substructure can be provided with a PVC coating on one or both sides.

Flexibility

You can achieve maximum flexibility by purchasing panels that you cut and profile yourself in your workshop.

Profiling/contour

There are no limits when it comes to profiling. Individual tools are not absolutely necessary, which allows us to profile even small quantities cost-effectively. We supply the individual substructure for YOUR lift and slide door.

The stacking contour (tongue and groove plug-in connection) allows different stand-off heights to be achieved flexibly.

In addition, processing with our CNC 5-axis milling machine is possible up to 4700x600x300mm in one piece for highly complex and individual requirements.

Saws

COMPACFOAM can be easily cut to size using commercially available saws such as circular saws, pressure beam saws or hand-held circular saws. It is important to use saw blades with a wide tooth spacing and free chip space.

For the cutting of COMPACFOAM we recommend saw blades with flat teeth and chip thickness limiter and very large tooth pitch. Optimum cutting results are achieved at 2000 rpm.

Saw blade recommendation

Diameter 300mm:
12-16 teeth

Diameter 400mm:
16-20 teeth

Diameter 450mm:
20-26 teeth

Sustainability

With the help of a newly developed process, particle technology, we can reduce the waste of COMPACFOAM recycle to 100 %. CFeco200, the result of this process, offers the same good properties as COMPACFOAM: high strength with excellent thermal insulation.

The two base layers of the COMPACFOAM-Sliding substructures are produced in CFeco200 as standard. This means you are using a substructure system that is largely made from recycled material. If you opt for the solid core version (substructure without insulating core), you can even work with a substructure made from 100 % recycled material.

In any case, you increase the proportion of recycled materials in construction and improve the eco-balance of your project and company. Because environmental protection means keeping things in circulation instead of disposing of them at great expense.

Assembly instructions

1. air and water tightness

Apply two beads of adhesive with a width of 8 mm to the substructure and attach the door threshold. Use an MS polymer assembly adhesive for this. To avoid wastage, you can butt join the profile. The butt joint must be glued airtight and watertight with the MS polymer assembly adhesive.

2. assembly of the substructure

Screw the threshold and the substructure into the base layer using window frame screws (Ø 7.5 mm). The screws can be screwed in from above or below - both variants are possible.

The distance and anchoring length depend on the structural requirements or the RAL installation guide. Pre-drilling in the insulation profile is not necessary.

The two solid load-bearing layers on the inside and outside safely transfer the heavy weight of lift and slide doors into the building structure.

3. installation

Install the system point by point on shims in accordance with recognized technical rules. For static load transfer, the screws are attached using mounting brackets and window frame screws. Pre-drilling in the insulation profile is not necessary. The mounting bracket can be robustly screwed into the wide base layers.

Wind pressure, wind suction and ETB forces are absorbed by the counter-milling and the mounting bracket.

4. external sealing

The following materials can be used for sealing:

EPDM film (0.8 mm)

Liquid plastic

Bitumen sheeting

Waterproofing with a bituminous membrane is also possible if carried out correctly.

Further information on sealing can be found here.
