Technitherm is a closed cell polyurethane cavity wall insulation foam which is injected into the cavity of the property.

Foam cavity wall insulation u value.

Cavity wall insulation overview. We cater for domestic commercial industrial customers. Most cavity insulation installed since the 70 s is what known as foam board or styrofoam or air board insulation panels. The u o factor for all frame walls is based on the r value of cavity insulation and the continuous insulation r value if used.

When continuous foam insulation is specified 100 of the wall is assumed to be covered at the specified r value. The entire wall is assumed to have structural sheathing. For more information see our articles and how to videos below. U values are expressed in units of w m2 k.

The lower the u value the greater a product s resistance to heat flow and the better it s insulating value. If the user does not enter a continuous. Injected pu foam is a two component chemically modified polyurethane foam which achieves superior u value and air permeability results. In general how the insulation s method of installation can give you an idea of how it compares to other types of insulation.

Now on paper they have great insulation values but when placed in your cavity by block layers or bricklayers they have a huge weakness. Usually white and very light. Find your zone on the map and then use the chart to determine the level of insulation you need to properly insulate your attic walls floors and crawlspaces. Call 353 1 276 8512.

Isothane s foam cavity wall insulation technitherm has a proven track record of providing structural stabilisation and thermal insulation benefits to both domestic and commercial properties across the united kingdom for over 25 years. The easiest way of getting a u value calculation is by using our free online u value calculator. These can be supported with a detailed report. Building regulations now specify that walls must adhere to specific u value standards thermal transmittance so many properties already have cavity wall insulation.

U value ratings generally fall between 0 16 and 1 20. If you do and it consists of blown mineral fibre or polystyrene beads and you re still receiving high energy bills we recommend switching to expanding foam insulation. The r value is the reciprocal of the conductivity of a material and is the measure of the capacity of a material to resist heat transfer. We provide u value calculations to show compliance with current building regulations standards and best practice.

Blown in or loose fill insulation insulation blankets batts and rolls spray foam insulation and foam board insulation. Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation.
