VST 50×30

Support profile

VST 50×30 profile
VST 50×30 in a window assembly
Cross-section dimensions of VST 50×30

Description

VST 50×30 covers the lower junction of windows and doors at a mounting width of 50 mm. The 30 mm mounting height is the ordinary joint. What sits under the frame is high-density EPS rather than a hollow plastic support profile conducting cold into the room.

Application

As a support profile in PVC and aluminium translucent structures, to improve the thermophysical properties of the lower junction.

Frequently asked questions

Which profile width do I need?

The first number in the article code is the width of the thermal-break support profile, and it follows the mounting depth of the profile system. The manufacturer draws the lower joint for every system and shows there which size fits it. Check your system on the compatibility page before ordering.

What length is supplied, and how much of it is usable?

A bar is 1200 mm. The working length, after the mounting allowance, is 1180 mm, and that is the figure the requirement per opening is calculated from. All 9 sizes ship in the same length; only the cross section differs.

Does it take up moisture at the lower joint?

Water absorption is 0.5 % after long-term immersion, measured to EN 13163. It matters more here than in the wall field: condensate and moisture from wet trades collect at the lower joint, and the material sits under the frame for the service life of the window.

What reaction-to-fire class does the profile have?

Class E, to EN 13501-1. The value is the same across every size because the material is the same. An element class does not describe the assembly: fire safety requirements for a project are checked on the whole joint, together with the window and the surrounding insulation.

What does the classification code on the data sheet mean?

The code EPS-EN 13163-CS(10)1900-WL(T)0.5 is the EPS designation under EN 13163. It names the material, the standard, the compressive strength at 10% deformation and the water absorption after long-term immersion, the same values as the specification table, written in the form CE marking requires. It compares directly with another manufacturer's designation.
