Which Bradford Optimo is right for me?

The first decision to make is what width of Bradford Optimo to use. If the timber floor joists are spaced at a standard 450mm or 600mm from centre to centre, then either the 415mm or 565mm Optimo Underfloor insulation will fit perfectly. If you find that the spacing between some of the joists is irregular, you may need to use a sharp knife and cut the insulation to fit. Allow around 5mm extra on either side to ensure a tight fit between the underfloor joists.

You will also need to consider which R-Value insulation you need. This relates to the effectiveness of the insulation. “R” stands for “resistance”, so the higher the R-value the better the insulation performance of the product, and the more effective it is in reducing heat transfer. Optimo underfloor comes in R2.1 and R2.5 varieties. R2.1 is suitable for temperate climates and R2.5 is recommended for very cold climates. All the Bradford underfloor insulation segments are 1160mm long.

To calculate how many packs you will need you first need to measure the area of flooring to be insulated. This can only be done by inspecting the sub-floor area as you need to determine whether access is available for the entire floor.

Once the area of floor to be insulation is determined, deduct about 10% to allow for timber framing, and then divide the remaining area by the amount of square metres of insulation in the bag, noting that this will vary depending on the R-value and thickness of the insulation.
