retrofit wall insulation

why is it so important?

Can you inject Spray Foam Insulation through plasterboard/Lath and Plaster?

We get asked this question on a weekly basis. Trying to upgrade the insulation in an occupied room may seem quite daunting to you but to us, it’s second nature. Energy efficiency depends on good levels of insulation. The use of a breathable material is good practice to mitigate moisture risk. Airtightness (or reduction of draughts) is an often- overlooked aspect of energy efficiency which can make a huge impact on the warmth and comfort of your home. Using an airtight insulation will ensure you are creating a warm, comfortable and efficient home. 

Using a thermal imaging camera, we will gauge where your studs are in your wall/roof. From here, we drill 10mm holes periodically through your wall/roof and inject our spray foam through the holes. Our thermal imaging camera will confirm the foam has the correct coverage and if there are any cold spots, we just drill another hole and inject some more foam in. Once our job is completed, we ask that the holes are filled by others made ready for your painter. If you are ok with the thought of some disruption, then you’ll be delighted with the benefits this application brings.

Room in roof applications are very popular. We insulate from the wall head (where your roof sits on top of the wall) up to the ridge, spraying onto the underside of your roof. Where we can access in your eaves space, we will insulate here at 100mm. This is straight forward spraying. In the occupied area of your roof, we will either cannon tip our foam from the eaves or inject (like described above) through your plasterboard. Unfortunately, as we have no control over the foam in this area, we need to full fill the void space. The depth of foam here will be slightly deeper in this area. Next stage is to cut an access hatch in your ceiling, this allows us access into the ridge of your roof to complete the application. We say it’s like pulling a woolly hat over your head.
