Draught Sealer

Liquid sealing system to reduce air leakage through windows and doors.
Climate Change Mitigation Retrofit

Problem Addressed

Air infiltration in buildings is a large source of wasted energy as an estimated 81% of the heat generated in a building is lost through the building fabric. Heating systems must compensate for heat lost through leaky windows and doors, resulting in higher energy bills and more operational emissions.

Solution Overview

Quattro Seal Draught Sealing by The Energy Savers is a liquid sealing system that deforms to any shape and style of window irrespective of fabric or size. It is applied to frames and gaps to form a bespoke engineering grade gasket for each individual window or door and is particularly effective where there is a variation of gap sizes due to bent or chipped frames as it fills all gaps completely. Quattro Seal can be used universally across all styles of windows and doors (hinged, pivot, sliding sash and louvers) and all frame materials (metal, aluminium, wood, glass, and UPVC).

Additionally, Quattro Seal can be used to treat cracks where frames meet walls, under sills, exit service pipes, loft hatches and more. Installation is undertaken internally with no scaffolding required. All windows and doors will work after treatment exactly the same as they did before.

Benefits of Quattro Seal:

  • Recognised by English Heritage for use in Listed Buildings.
  • Energy savings from faster warm-up times and longer heat retention.
  • Boilers activate less frequently prolonging their life.
  • A warmer environment has positive outcomes for health and recovery.
  • Increasing air tightness improves sound proofing up to 10db.
  • A standalone fit and forget measure.

The typical ROI for Quattro Seal is under 3 years, and carbon savings typically cost less than £100 per tonne. The Building Research Establishment found that Quattro Seal CO2 savings are higher than standard draughtproofing CO2 savings by a factor of between 2.3 and 2.4. Independent BRE test results verify that the energy savings achieved by Quattro Seal are up to 27% for a typical office building which far outweighs those achieved by conventional draught proofing. This was based on air pressure testing which found a reduction in air leakage of 53%.

Case Study

Quattro Seal has been installed in 6 branches of Lloyds Bank with air pressure testing of each site before and after installation as part of a successful pilot scheme. The results were an average reduction in air leakage of 35.77% which Lloyds calculated to be an average annual energy savings of 18%. The Energy Savers have been commissioned by Lloyds to roll out Quattro Seal across a further 79 branches nationwide.
