TMW gluing

skleikaTMW by virtue of increased frailty and poor resistance to compression is not suitable for the manufacturing of self- supporting structures such as beams, cantilevers, supports, columns.

For TMW connection it is better to use of special metal connecting pieces: SIMPSON, SHERPA, SIHGA, and FISHER.

Thermally modified pine and spruce glue up poorly. Or it is better to say that they glue up normally, but when soaking some wood fibers start detaching from the glue plane, which often leads to element segregation in general.

There are no complaints with regard to soft TMW gluing for use indoors or under cover. Where there is no danger of soaking and swelling the glued elements behave normally. One can surely glue up doors, furniture, panels, stairs and other interior pieces, both solid and lamellas of 3 – 6 mm as well.

Important: Do not pinch the glue up surface, as the plane will squeeze too much glue and remaining glue thickness can be insufficient for adhesive joint good quality.

The photos clearly demonstrate how pergolas elements are separated along gluing line upon soaking (photo taken in spring). At that, the strongest glue D5 was applied. There are no complaints with regard to the glue itself as well as in respect of wood, but features of the materials have led to such kind of unpleasant effect. Subsequently the construction was rearranged and covered on top with a metal drip.
Hard TMW (ash, gum, oak) you can use the polyurethane glue.

We prefer to construct large and supporting structures, frame houses and pergolas using metal and panel it with TMW.
Photo 2 shows a gazebo made of shaped tube and covered with boards of thermally modified spruce.


Glued elements can be used in sub-constructions of terraces, fronts and furniture.

If you still have to glue, in any case, the adhesive joint should not have direct contact with water or be applied horizontally. Moreover, we do not recommend polishing the adhesive joints but making beveled edges.

We recommend using TMW glued elements in buildings and structures that do not have an active and frequent contact with atmospheric water.
