SOLID WALL INSULATION WITH FLEXIBLE THERMAL LININGS
Flexible thermal linings are insulation on a roll specifically for use in solid wall homes, mansard roofs and dormer ceilings. The lining is 10mm thick and supplied on rolls one metre wide, 12.5 metres long. This provides an immediate improvement in the thermal comfort as it is not necessary to heat the thermal mass of the house.
Composition & Durability
The material is made from a natural product – latex - in an open and closed cellular construction and has a durable fibreglass face that can be decorated with emulsion, wallpaper or even tiled.
• Flexible thermal linings have been tested by the National Physical Laboratory – May 2001
• Approved by the Energy Saving Trust as an energy saving product for inclusion in the Energy Efficiency Commitment Scheme. June 2001.
• Is an Energy Saving Trust ‘Recommended’ product for the insulation of solid wall homes. Oct 2004
• BRE Assessment of energy savings for SEMPATAP THERMAL on Mansard roofs and Dormer ceilings. Sept 2005
• EST Approval for SEMPATAP THERMAL used on Mansard roofs and Dormer ceilings. Oct 2005

4 Water:
The material is moisture vapour permeable and will not trap moisture in the substrate.
Application
1 Survey:
A pre-installation survey is carried out to calculate internal wall measurements and identify levels of preparation.
2 Site Preparation:
All wallpaper applied to inside of external walls is removed and sound painted areas are cleaned ready for the application of adhesive. Porous or powdery surfaces must be pre-primed with the appropriate primer. If in doubt contact the manufacturer for specific recommendations. If necessary apply skirting channel with suitable no nails type adhesive and allow to dry.
3 Installation Procedures:
Cut drop lengths of the Flexible thermal lining allowing 2-3cm overlap at each end. Apply the system adhesive directly to the wall for the first metre width. Hang cut length and smooth out to remove any air bubbles. Trim top and bottom . The operation is repeated along the length of the wall to be insulated. However when the adhesive is applied to the wall for all subsequent lengths it is also applied to the joining edge of the previous piece. On all outward-facing corners and reveals etc. Edging Tape is used to form a neat and protective corner finish. All joints with the ceiling, untreated walls, skirting and between the hung lengths of the thermal linings are sealed with the system sealant.
4 Making good:
The insulated wall areas can then be decorated with emulsion, wallpaper or even tiled as required.
