Thermolan® TP 116
Description
TP 116 is a semi rigid batt of unfaced glasswool, which is available in a range thickness to suit various building applications. TP 116 is designed mainly for the thermal and acoustic insulation of timber framed external walls.
Applications
TP 116 is suitable for the following applications:
External Timber Framed Walls
For combined thermal and acoustic insulation in external timber frame walls TP 116 should be installed between the studs but with airspace between the insulation and the external cladding.
Internal Partition Walls, Internal Floors and Suspended Ceilings
For acoustic insulation of internal partition walls with steel or timber frame, TP 116 can be installed in the cavity between the sheets of plasterboard. As the acoustic insulation of suspended ceilings it is laid on steel or timber understructure. TP 116 with its air flow resistance 5 kPa.s.m2 and average density ≥ 15 kg/m3 meets requirements for acoustic insulation of most common plasterboard systems.
Pitched roofs
For combined thermal and acoustic insulation of pitched roof type construction, TP 116 can be installed between rafters. TP 116 is semi-rigid for easier fast 'friction-fit' installation
Installation - External Timber Framed Walls
Preparation
- Determine the thickness of insulation needed taking into account the requirements of the thermal regulations and the thickness of the vertical timber studs.
- For existing buildings, check the condition of the external wall and ensure that there is airspace between the insulation and the external wall.
- For new buildings, nail timber battens to the vertical studs to create a ventilation air space between the insulation and the external wall.
Fixing the TP 116
- Cut the batts 10 mm greater than the space between the vertical studs of the frame to enable ‘friction-fitting' - ensure that there are no gaps.
- Lightly press the batts between the vertical studs of the frame.
- Staple a vapor control layer to the vertical studs on the heated side of the construction.
- Fix the chosen internal lining and its finish to the interior.
Installation - Internal Partition Walls and Suspended Ceilings Preparation
- Determine the thickness of insulation needed. In most cases you should respect criteria given by plasterboard systems suppliers to reach required sound reduction.
Fixing the TP 116
- For internal walls, there is no need to cut the batts in standard steel frame which have studs at centers 625 mm. In case of any other distance, cut the batts 10mm larger than the space between the vertical studs of the frame. In suspended ceilings, use entire batts and adjust between the hangers positions.
- For internal walls, lightly press the batts between the vertical studs of the frame. Fill tightly the whole height of the partition. In case of ceiling the whole area must be covered.
- Fix the boards on the other side of the partition or the boards of ceiling.
