1. Solid Ground Floor Scroll over copy While insulating the floor of an existing building is a disruptive process it shouldn’t be disregarded completely as there are significant benefits in terms of reducing heat loss. Also if part of the remedial work includes plumbing upgrades then it might be prudent to take advantage of this opportunity to provide insulation as the concrete screed will need to be excavated to some extent.

External rendered insulation system Scroll over copy This is an ideal system to upgrade the thermal performance of an existing building as all the work is carried out externally. Low U-Values are very easily achieved, even exceeding current building regulations for new build! The roof eaves can be adjusted slightly to take into account the additional depth of insulation and proprietary aluminium cill extentions can be used to dress over the existing concrete cill.

Cold Pitched Roof Insulating an existing sloped ceiling may be achieved by fitting an insulated plasterboard directly to the underside of the existing plasterboard, but ideally the existing plasterboard should be removed and a new layer of insulation fitted between the rafters, and insulated dry-lining fitted under the rafters.

(all 12.5mm plasterboard) 4. Warm Pitched Roof This particular system will require removal of the existing slates or tiles and therefore may only be feasible when these need to be replaced as part of the remedial works.

Flat Ceiling Insulation already present in a flat ceiling may have deteriorated over the years depending the type, and length of time it has been there. Replacing the existing insulation with Kooltherm K7 between the joists, and the addition of Kooltherm K17 or K18 insulated plasterboard beneath the joists will ensure improved thermal performance of the ceiling for the lifetime of the building.

(all 12.5mm plasterboard) 6. Internal Dry-lining Traditionally internal dry-lining has been the preferred method of improving the thermal performance of existing walls. Using premium performance Kingspan Kooltherm K17 or K18 products will ensure the thinnest and most effective solution and will considerably reduce heat loss. It is also ideal to accompany K7 in Cold Pitched Roof and Flat Ceiling upgrades.
