Add Just It - self adhesive shims

Use Add Just It in all types of installations such as Windows, Doors, Kitchen interiors Bathrooms and Floors. You will save time and money and the results will be straight and exact. If needed you can easily bend, cut and nail or screw through the shims.

The pieces are self-adhesive and are delivered in blocks consisting of 13 shims in each block. The thickness of the shims vary between 1 mm, 2 mm and 3 mm and each shim has its own color separated by a black shim of the same thickness.

The black colored shims are there to assist you in optically measuring the number of shims needed for each application, thus eliminating the use of a measuring device.

Add Just It blocks are made of polystyrene which is climate sustainable, even for the harsh Nordic conditions.

Add Just It also functions as a moisture barrier between cement, stone and wood in foundations and in window installation.

About the company

7stera AB was founded 2010 with the goal of developing a product which main objective was to save time and money within the building and construction industry. The founder and CEO developed a simple and effective product named Add Just It.

After studying the extensive and unnessesary long time professional builders used sawing masonite plywood, etc for use as shims in all types of mounting and installation the idea of Add Just It was born.

Save time and money!

To save time and money (same thing) is of course interesting for the project manager of a large building project as well as for the private home owner working on smaller projects

EXAMPEL (SWEDEN)

A carpenter costs approximately 450 SEK per hour (EUROS 52.5)

Divide 450 SEK per hour by 60 minutes = approximately 7 SEK per minute. (EUROS 0.81)

It’s not economically defensible for a building company or the private homeowner to pay 7 SEK per minute for a qualified carpenter to waste valuable time in sawing and fitting different pieces of Masonite, wood every time he has to adjust something.

QUOTE FROM BERT:

”In respect to the fact that we put people on the moon over 40 years ago. It’s not reasonable that we are still mounting and installing door, windows etc. as we’ve been doing for 300 years.”
