Myth: Insulation Isn’t Really Important. I’ll Get To It Later If I Have Time/Money

Fact: Insulation is one of the smartest investments in your home you can make

Insulation provides year-round comfort and savings in many important ways:
  • It lowers your bills by making sure you’re minimising energy
  • It helps the environment by wasting less gas
  • It reduces the chance of respiratory problems or allergies by keeping you in control of moisture and indoor air quality
  • It keeps your home quiet and comfortable and helps with soundproofing

Why Insulate?

Insulation is one of the smartest investments you can make in your home because it provides year-round comfort and savings in many important ways: 
  • Increase energy efficiency - Lower energy bills
  • Quieter, more comfortable living
  • Healthy home, healthy environment
  • Moisture control - Manage Indoor Air Quality

Myth: It doesn’t really matter where or how I install my insulation

Fact: There are a few best practices in maintaining air quality control through insulation, ventilation, and heating. 

Floor Insulation

Installing an underfloor insulation will compliment the insulation work done in the roof space. We also recommend laying over the ground, a ground vapour barrier ( 250mg Permathene black Plastic) this will eliminate the rising damp moist air entering your house through the floor.

Retrofitting older houses

N.B when Retrofitting older houses there is a number of different insulation brands that could be found already installed between the timber joists.

This is where a blanket to cover the existing insulation will be of most benefit. Covering the segment insulation and joists with a blanket - creating a Double layer insulation - will reduce the potential for thermal bridging (heat loss through exposed timber) - This is the most effective and efficient insulation method.

Whole-House Insulation and Ventilation Solutions

Installing a Drivaire Home Ventilation unit will help eliminate condensation, creating a warmer, healthier & dyer home that is far more cost efficient to heat. This total insulation solution will help towards reducing energy bills, creating a warmer, comfortable and much more efficient home to heat in winter while summers will be much cooler.  

Insulating Ceilings

To effectively insulate the ceiling space it is of great benefit to installing segment between the ceiling joists , then installing a blanket at right angles to joists.

Myth: All Thermal-Resistance Is The Same

Fact: R-Values are not all created Equal

The R value or R-value is a measure of thermal resistance, used in the building and construction industry. The bigger the number, the better the building insulation's effectiveness. R-value is the reciprocal of U-value.

Around most of the world, R-values are given in SI units(metric), typically square-metre Kelvin per watt or m²·K/W . In the United States customary units, R-values are given in units of ft²·°F·h/Btu (imperial). It is particularly easy to confuse SI and US R-values, because R-values both in the US and elsewhere are often cited without their units, eg R-3.5. 

Convert Imperial (US) R-Values to Metric (SI) R-Values

R(imp)/5.678263 = R(SI) 

An important note for houses with enclosed ring foundation construction 

This under floor space is susceptible to higher levels of moisture - we have experienced a greater number of houses we insulate with serious damage to bottom plates and flooring caused by the exposure to consistently high levels of moisture. Compared to the very small cost of installing an effective Ground Vapour Barrier, the preparation costs and remedial work involved caused by the lack of moisture barrier is significant.
