Wall Insulation

Wall Insulation

 

Introduction

Masonry cavity walls comprise of an outer skin of brick or blockwork, and an inner skin of masonry. In new buildings, the inner skin is usually blockwork. Between the two masonry leafs is an air cavity, into which thermal insulation is installed to meet building performance targets. A partial fill cavity features rigid insulation boards secured to the inner leaf masonry, leaving an air cavity behind the outer leaf.

Partial fill external walls can contribute to a whole-building solution that meets the energy efficiency target for new-build construction. They are particularly well suited to extensions of existing buildings, where the U-value targets tend to be less onerous

 

High performance, partial fill insulation offers the following benefits:

  1. Easy to fit between wall ties using cavity tie clips for retention.
  2. Reliable long-term energy savings for buildings.
  3. Low emissivity foil facers improve thermal performance of air cavity.
  4. Excellent dimensional stability.

What products are suitable as partial fill cavity insulation?

Offered specifically for partial fill cavity wall applications, Celotex CW4000 is sized specifically to fit standard wall tie spacing requirements. No cutting is required, so it can be installed quickly and easily as the brick and blockwork courses progress.


WHY IS PARTIAL FILL CAVITY CONSTRUCTION SO COMMON ?

Using rigid insulation boards in conjunction with a minimum 50mm air cavity is a tried and tested solution familiar to designers, specifiers, contractors and building inspectors alike. It is a popular method for constructing external walls in the UK, and has been used on building sites for the last hundred years.

The clear cavity between the outer leaf and the insulation acts as a barrier to external moisture, stopping it from reaching the inside of the building. Most commonly, the outer skin of the cavity wall is constructed from brick. Blockwork is also used, clad or rendered to provide the desired finish.
