Free U Value Estimation Service

Planning a loft conversion and want to know how thick the insulation should be to comply with the current building regulations?

We offer a free U value estimation service which uses up to date software from the UK Building Research Establishment (BRE). Please send us an email with the following information, and we will glady provide you with an estimation of the U value for various insulation thicknesses:

For roofs:

• Pitched or flat?
• Construction - tiles, felt/membrane, rafters etc?
• Is loft space currently ventilated at eaves or elsewhere?
• Proposed construction of the insulated roof?
• Is there any other insulation present? If so, what, where and how thick?

For walls:

• Construction - cavity, solid, timber frame?
• Materials - stone, blocks, bricks etc?
• Is there any other insulation present? If so, what, where and how thick?

For floors:

• Construction - slab, suspended etc?
• Material?
• Is there any other insulation present? If so, what, where and how thick?

We are also more than happy to post you a print out of the U-Value calculation (our U-Value calculations are worked out on BRE software) with your order.

Please make certain you include a contact number in case we need further detail.
