How to Install a Thermal Wall Membrane

Thermal wall membrane consists of 2 layers of pure form of aluminum foil with air cushion bubbles in-between. This membrane acts a waterproof barrier in addition to also acting as a thermal insulation. This is an ideal material to be used in basements as well as under the heated concrete floor slabs for waterproofing and insulation. This membrane is available in the wide rolls and as foil joining tape. Waterproofing and thermal insulation of walls and foundations are very vital to avoid any water from getting inside causing damages. If you fail to insulate the walls and foundation properly, it will result in damage to the insulation. It will also affect the efficiency of insulation.

Tools and Materials Needed:

  • Scarper
  • Waterproof Membrane
  • Sugar soap
  • Scissors
  • Staple gun
  • Tacks

Steps 1 - Preparing the Walls

Clean the walls with scraper to remove any portion sticking out from it. Wipe off all oil, grease and dirt using sugar soap.

Step 2 – Taking Measurements

Take out the measurements to estimate the quantity of the insulation material required. Note down the sizes of different walls as you measure them and mark them lightly with pencil with a number. You can get the sufficient quantity of membrane material to cover up all the area after estimation.

Another way is to select the insulation materials, which have waterproof membrane already stuck to them. This way you have to cut and fit only one thing to the wall. If the insulating membrane is fixed properly, it will provide the complete protection required by you.

Step 3 - Marking on the Waterproof Membrane

Take the sizes of the wall noted by you, and start marking on the membrane the pieces to be cut according to the sizes of the particular walls numbered by you. Mark on the sketch the pieces to be put together and mark on them also. Mark the measurements on all the pieces of waterproof membrane also. This will make both cutting and installing easier. You have to cut the pieces accurately to the size.

Step 4 – Cutting

Cut the pieces according to the marking using a pair of scissors. Ensure that you cut the right sizes. You should have the membranes for all the walls.

Step 5 - Fixing the Membrane

Fix the pieces of membrane on the respective walls. Refer to the sizes noted by you and the numbering on the walls and membrane pieces. Use a staple gun or tacks to fix the membrane to the walls. Overlap the joints and apply joining tape. You can stop moisture to seep through the joints and insulate them.

Step 6 – Fixing the Insulation

Fix the insulation on the walls, which are covered with membrane and waterproofed. This will ensure more warmth for you in the house. Fix the insulations properly on the wall.

Step 7 – Finishing

You can finish the wall with drywall and plaster. The finished wall will look better and the insulation will last for long time.
