Step 1: Fit the level screws

Start by fitting ESSVE level screws in the bottom edge of the opening. Then stand the frame in the opening and adjust the level screws with the matching adjustment tool so that the bottom edge of the frame is level. Level screws make the work efficient and replace both wedges and packers.

Step 2: Secure with Pumpbag inflatable cushions

Temporarily secure the frame with Pumpbag inflatable cushions. Use a spirit level to check that the window is plumb in all directions.

Step 3: Centre

First insert a C10 centring sleeve into the bottommost hole in the frame on the hinge side.

Step 4: Concrete drill bit

Drill through the hole with a 10 mm diameter concrete drill bit, but without hammer action – hammer action enlarges the hole in lightweight concrete and can break the thin webs in hollow brick (the only exceptions are special drill bits that the brick manufacturer also approves for drilling with hammer action). Make sure you drill at least 120 mm deep into the wall. Then remove the centring sleeve.

Step 5: Plug

Fit a lightweight concrete plug onto the Programa Plus frame screw and push it into the drilled hole. Set the installation key in the cordless screwdriver to the installation position. Once the whole plug has been pushed into the wall, start screwing. Drive the screw in far enough that its unthreaded part is visible in the gap between the wall and the frame (marked in green in the picture).

Step 6: Centre

Continue with the top hole on the same side (the hinge side). Insert the centring sleeve, drill the hole, remove the sleeve, push the frame screw with its plug into the hole and screw it in. Continue on the opposite side. If the frame needs fine adjustment, turn the installation key in the cordless screwdriver to the adjustment position.

Step 7: What about a larger frame?

When installing door frames or larger window frames: once you have fitted screws in the topmost and bottommost holes, continue with the remaining holes in the middle of the frame.

Step 8: Cover caps

For a discreet look, cover all the holes with cover caps. The cover caps come in several colours.

Step 9: Insulate the gap

Fill the gap between the wall and the frame with gun foam. We recommend Expand gun foam, with an isocyanate content below 0.1%, which provides good sound damping and thermal insulation. It adheres to most materials, e.g. wood, metal, concrete, stone, foam plastics and extruded polystyrene.

Isocyanates – mandatory training!

Because working with isocyanates carries a risk of allergy, since 24/8/2023 anyone who works industrially or professionally with products containing 0.1% or more diisocyanates by weight, or who supervises such work, must complete training. The obligation arises from Commission Regulation (EU) 2020/1149 (REACH, Annex XVII, entry 74). More about isocyanates and mandatory training
