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

Start the installation with the bottom hole on the hinge side. Insert a C10 centring sleeve into the pre-drilled hole in the frame.

Step 4: Drill a hole into the wall

Drill through the centring sleeve with a 10 mm diameter concrete drill bit. Drill at least 80 mm deep into the wall. Then remove the centring sleeve.

Step 5: Installation position

Fit a nylon plug onto the frame screw and push it into the hole you have just drilled. Only start screwing once the whole plug is in the wall. Then set the installation key in the cordless screwdriver to the installation position. Drive the screw in far enough that its unthreaded part is visible in the gap between the wall and the frame (the green area in the picture).

Step 6: Fit the frame screw

Then continue by fitting the frame screw in 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. When you have finished one side, continue by fitting the frame screws on the opposite side. If the frame needs fine adjustment, use the installation key in the adjustment position.

Step 7: What about a larger frame?

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

Step 8: Cover caps

Cover all the holes with cover caps. Cover caps come in several colours, so the fixing will be discreet.

Remember!

Depending on the season, the timber in the frame, stud or wall may swell or shrink. The installation may then need fine adjustment. Remove the cover caps and realign the frame using the installation key in the adjustment position.

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
