ProofTherm Insulating Screed combines Perlite and Pumice aggregates to create an ultra-lightweight screed underlay with excellent insulating properties.
Perlite and Pumice are naturally occurring volcanic rocks that form with a highly aerated honeycomb structure. These tiny air bubbles trapped in ProofTherm’s aggregates create a barrier to thermal conductivity and also reduce acoustic transmission.
ProofTherm screed can be used as an underlay to insulate floors at depths between 20mm and 120mm, either directly onto an existing slab/substrate or in combination with a damp proof membrane.
ProofTherm insulating screed is not designed to provide a permanent wearable surface and should be finished off with a durable self-levelling screed/compound or final decorative surface.
Weight: 25kg bag
Coverage: 4m2 per 10mm applicable depth
Colour/Appearance: Grey granule
Drying time: Approx. 24 hours per 10mm
Question:
Can I install a floating engineered wood floor directly on to a self levelled 20mm ProofThem screed?
Answer:
Hello, we are not sure, we would suggest reading the products datasheet, or call our team on 01752 692206.
Question:
What is the u-value at 20mm thick
Answer:
This product has a thermal conductivity of 0.1 W/m2 K
Question:
We are converting an existing garage which is 25-30mm below the adjoining floor level. Is this enough depth with your product to meet building regulations for thermal floor insulation ?
Answer:
Unfortunately we are not able to comment on what can meet/pass/exceed building regulations.
You are welcome to contact the ISS on the contact number provided on our website, and one of the team can happily source the information from the Manufacturers for you.
