Downlights and Condensation!

The Problem with  Untreated Downlights!

 
 
 

 
 




 



 The lounge is warm, and occupied. Temperature is say 21°C at ceiling level.
 The Loft temperature is say 5°C
 The Outdoor (ambient), air is say 0°C.

The illustration above, shows how a convection air flow is started by untreated/uncovered downlights in a typical house.
Warm air is convected through the downlights into the roofspace. When this air contacts the cold surfaces in the loft, the moisture it contains condenses and causes dampness and condensation.

Increase Insulation Performance!

Thermahood fitted over downlights can increase the performance of loft insulation by 50%. Stopping that heat escaping should be a priority and will also produce other benefits too; including reduced risk of condensation in the loft & reducing the dust and insect infiltration through the downlight fitting! 

Why Downlight covers are needed!

This image illustrates how warm and cold air can escape through downlights, see also the insulation missing from around the downlight which makes it easier for the warm and cold air to escape. These are the weak areas in your ceilings which lets your heat escape easily!

Why Downlight covers are needed!

With-out a Thermahood downlight cover, loft insulation is missing and cold air from the attic can enter the living area and warm air escape to the attic. 
There is also the risk of fibreglass, dust and insect infiltration!

Transforming Down-Lights - Part 2

Before undertaking any works always ensure health and safety is maintained.

230v GU10 Holder and LED BulbWith the power off, we disconnect our 
original transformer type Down-Light 
and replace it with a direct feed 230v 
GU10 Holder and 4 watt LED Bulb. 

This 4 watt LED bulb will save approx 90% 
on electricity cost compared to the 
original energy sapping 35-50 watt bulb.




Applying adhesive to a Down-Light Attic SealWe then apply adhesive to the Down-Light Attic Seal, there is a groove/recess specifically for 
this purpose. We recommend a water-based adhesive, this is solvent free.

Transforming Down-Lights - Part 1

This is how I changed my down-lights from Energy sapping, dangerous, money wasters to Energy friendly and safe LED lights. 
This is how I changed my down-lights from Energy sapping, dangerous, money wasters to Energy friendly and safe LED lights. This is my original money waster, as can be seen, it has a 12v transformer and a dichroic MR16 bulb 35 or 50 watt, there was gaps between the light fitting and plasterboard which allows warm air up through the fitting and cold air down through also. There was no insulation over the light fitting, this was correct procedure at the time of building. But it created a thermally weak area in my home insulation.

Dangerous Down-Lights.

 
Down-Lights can be dangerous when fitted like this!
Or when you put your Christmas decorations on them!
Or if you leave insulation too close to them.

This light needs to be moved away from the timber and covered with a 
Down-Light Attic Seal, so that it can be safe, air-tight and of-course keep
that heat in your home.

This has been a close call here, it could have been so different.

This needs to be moved away from the timber and insulation.
