Project Facts

Sandstone walls

Over occupied two bedroom tenement flat

Severe damp and mould

Wall moisture at 35%

Single glaze windows with limited insulation

3-4 air changes per hour

Net Result

5 days

Time taken for NexGen Infrared Heating to reduce the wall moisture from 35% to 5%

2 months

Average time for traditional heating systems to dry out properties to a safe moisture level

Remedial works can be started after 5 days with NexGen

Pre-installation Findings

Detailed findings based on convection air temperature sensor measurements:

Tenant Situation:

Tenants could no longer live in the property due to damp and mould conditions.

Issue:

Hard to heat property with no insulation and single glazed windows.

Current Heating:

The client was using a gas boiler

Heat dissipation:

Tenants commented on it being difficult to retain any heat and measurements were 3-4 air changes per hour in every room.

Post-NexGen Installation findings (no additional fabric measures)

Detailed findings based on third party analysis by Sureserve Asset Services:

NexGen Solution: Infrared Ceiling Paper

Moisture Reduction: Within 5 days, NexGen reduced wall moisture saturation from 35% to 5%.

Temperature Maintenance: Consistent heat of 73°F with minimal deviation during test.

Reduced Thermal Bridging: Glass temperature increased above internal air temp.

Temperature Decline: Once NexGen & comparable Gas property were turned off after 5 days it took NexGen 31 hours to revert from 73°F to 65°F and 61 hours to revert to an ambient 52°F. Gas took 2 hours from 73°F to 65°F with 3-4 air changes per hour.

Stabilised Humidity: Humidity now stable under 60%.

Energy Efficiency: NexGen creates thermal mass storage in building fabric, reducing losses and leading to lower energy usage.
