Insulation screws DS

The insulation screws DS consist of a wood construction screw (made of zinc-plated steel or of stainless steel) and a tightly moulded plastic head made from polypropylene.

The large plastic head has a diameter of 50 mm and prevents of thermal bridges and condensation water.

Insulation screws DS are primarily used for fastening insulation on wooden surfaces, such as solid wood, wood studding, OSB plates, chip boards etc.

In contrast to insulation nails Type II, they are also well-suited for fastening on elastic surfaces, such as wooden slats.

Insulation screws DS are used with a cordless screwdriver and a special bit which fits exactly into the hexagonal recess and transfers the force perfectly onto the screws.

Since insulation screws DS possess a closed, smooth head, they are primarily used in situations where no plaster is being used (e.g. in agriculture / stable or barn construction). 

If a structure is supposed to be plastered or the screws are used in a thermal insulation composite system (TICS), we recommend using optimised insulation plaster screws DPS.

The largest advantage of our insulation screws DS is the fact that they consist of one part only and not - like most competitive products - of 2-3 parts. That means no assembly and fumbling with holding on while turning in the screw.
Our screws can be used single-handedly. That saves time and money.
