Retrofitting older homes
EXISTING BUILDINGS USING BRACKETS:
- Measure joists to ascertain width needed.
- Cut or snap off the special “concertina edges” to ensure a snug tight fit between the floor joists (Note: The concertina edges must be tightly compressed).
- Push the trimmed RETROTHERM™ sheet hard up against the underside of the floor.
- Place the RETROClip™ bracket against the sheet and hammer into the floor joist. RETROClip™ brackets should be placed one either side of the sheet, 400mm in from each end.
EXISTING BUILDINGS USING ADHEISIVE:
- Measure joists to ascertain width needed.
- Ensure all surfaces are clean and clear of debris.
- Cut or snap off the special “concertina edges” to ensure a snug fit between the floor joists (Note: The concertina edges must be tightly compressed).
- Apply a continuous bead of adhesive in an S pattern across the wooden flooring, allow 30 seconds to allow the residual solvents to evaporate.
- Fix the RETROTHERM™ sheet onto the underside of the flooring.
