Wooden interior door frames: fixed easily, quickly and environmentally friendly

Easy, fast and environmentally friendly installation of wooden frame frames, without the use of wedges, clamps and (chemical) mounting foam; the Häfele Frame Fix makes it possible. Not for nothing is the innovative frame fixing set being embraced by more and more carpentry factories, door/window manufacturers and installation companies.

Traditional assembly of wooden door frames is not only labor-intensive and complex, but also very time-consuming, says Michel Mulder, Product & Category Manager at Häfele Nederland BV.

"After all, it is not easy to fit the frames properly into the available space. Moreover, the assembly requires quite a few tools and instruments. Consider not only hammers, drills, electric screwdrivers, frame tensioners, screws and dowels, but also the chemical polyurethane foam (PUR foam). After installation, the frame must be adjusted horizontally and vertically by means of adjusting wedges and clamps and firmly secured, after which the profile anchors can be attached and the PUR foam can be applied. The Häfele Frame Fix greatly simplifies this process."

Immediately after installing the wooden frame, the door frame can be installed.

Easy positioning and securing

Häfele Frame Fix consists of three parts: a base plate, a fixing angle and a mounting angle made of galvanized sheet steel, which can be used to easily mount door weights of up to 40 kg. "To mount a frame, you need six sets of Frame Fix. Each set consists of a base plate, a fixing angle and a mounting angle," Mulder said.

"The mounting plate is simply screwed onto the frame, then two clamping plates are attached to it. The first clamping plate - the fixing angle - is already applied before the frame is put in place. The second clamping plate - the mounting bracket - can then simply be slid over this and clamped around the wall. Through two bolts, the frame can then be easily positioned and secured."

The mounting plate is simply screwed onto the frame, then two clamping plates are attached to it.

A major advantage of Häfele Frame Fix over traditional assembly methods is that the frame can still be easily adjusted at the time of installation. "Moreover, installation is not dependent on temperature or humidity. Also, no chemicals, such as PUR foam, are needed to fix the frame. This makes the assembly not only environmentally friendly, but also better for our health. When the wooden casing frame reaches the end of its service life and needs to be disassembled, the various parts can be easily disassembled and disposed of separately. Removing the door frame and unscrewing the bolts is sufficient for this."

Häfele Frame Fix is based on a clamping mechanism that aligns horizontally, vertically and to the side.

Huge time savings

At BAU Munich 2019, a prototype of Häfele Frame Fix was shown to the general public. Several pilot projects were subsequently carried out and some minor optimizations implemented, after which the Häfele Frame Fix was officially introduced to the market at the beginning of this year. The first reactions to the frame fixing set are very positive. Carpentry factories, door/frame manufacturers and assembly companies are seeing huge benefits, especially in terms of time savings, says Mulder.

"With the Häfele Frame Fix, wooden frame frames can be assembled in half the time! And although the initial purchase cost may be slightly higher than materials for standard assembly, processors more than recoup this during assembly. Moreover, fewer tools and operations are required for assembly, which also minimizes the risk of errors."
