Wall Insulation

Basic structure

WALLTITE^® exterior wall external insulation typically consists of 5 layers: substrate wall, WALLTITE^® spray polyurethane foam (SPF), primer, insulation levelling mortar, anti-crack polymer mortar with embedded AR mesh. Picture 1 below shows the structure.

Advantages of the system

Compared to panel exterior wall external insulation systems, WALLTITE^® exterior wall external insulation system has the following advantages:

• Higher R value because of low thermal conductivity
• Thermal setting insulation material, turns to char without melting when on fire.
• Self-adhesive insulation and no binder required
• Better adhesion to substrate, best suited for coastal areas with strong negative air pressure
• Seamless insulation best suit for curved or complicated exterior wall design.

Basic structure

WALLTITE^® exterior wall internal insulation typically consists of 4 layers: substrate wall, stud, WALLTITE^® spray polyurethane foam (SPF) and facade panel. Picture 2 shows the structure.

Advantages of the system

Compared with internal insulation by panels or loose filling insulation materials, WALLTITE^® internal insulation has the following advantages:

• Maximum usable internal room space because of its low thermal conductivity which translates to the lowest insulation thickness for achieving the same R value compared to other commercially used insulation materials.
• Self-adhesive spray applied insulation requires no binder for substrate wall; saves material and enables fast construction.
