WHY INSULATE EXTERNALLY
If your home does not have cavity in the walls, improving its thermal performance means insulating either internally or externally. Using external wall insulation has superior advantages for the following reasons:
- No need to sacrifice internal living space or square footage with the installation of interior wall insulation. External wall insulation affects only the facades or outside walls of your home.
- No reason to leave your home during upgrade or construction work when external wall insulation is being installed; that means no disruption your your family's schedule or lifestyle (as all the work is done externally)
- Healthier living environment. Thicker external wall insulation or plasters will result in warmer walls, which means no condensation (moisture) build-up or cold bridging; reduced mold growth and constant warm temperature inside (or cool interior during the summer).
- Constant even temperature through out your home. Cold and hot spots are eliminated as the entire home or structure is wrapped or blanketed externally in insulation.
- Improved external facades. There are many fine quality exterior finishes or plasters which can be applied to closely match your home's original exterior or similar nearby . So no need to worry your home's facades will be ruined or changed too drastically.
Mark the Styrofoam insulation board. Use a pencil or a marker to plot the desired length and shape of the rigid insulation board. If you don't intend for the markings to show up, use a pencil or a temporary marking device, and mark as lightly as possible. Use a ruler or a straight edged object in order for you to make neat lines. The outline that you make will serve as your guide for cutting.
