FrameTherm 38 Slab is a Glass Mineral Wool slab, designed to improve the thermal conductivity of your home or work environment. It is non-combustible insulation with the best possible Euroclass A1 reaction to fire classification and is manufactured using Knauf Insulation’s unique bio-based binder, ECOSE Technology. The slabs are odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould, or bacteria. These durable slabs when installed correctly have a never-ending life span. FrameTherm slabs contain no ozone-depleting substances or greenhouse gases.
- Designed to friction fit between timber studs, which prevents air movement and infiltration through or around the insulation, minimising heat loss.
- Ready cut to allow quick and simple installation, maximising on-site efficiency when compared with alternative insulants.
- It is CFC as well as HCFC free
- Provides thermal as well as acoustic performance.
- Easy to handle and install
- Allows for quick and simple installation, maximising on-site efficiency compared to alternative insulants.
- Extremely durable and long lasting.
- Awarded the DECLARE ‘Red List Free’ label. No ingredients in the product that are on the red list – including formaldehyde or phenol.
The Knauf FrameTherm 38 Slabs are tightly compact and lightweight which makes storing and handing easy, as well as installing the insulation. For long term protection on site, the product should either be stored indoors, or undercover and off the ground. The slabs polythene packs are designed for short term protection only and they should not be left permanently exposed to the elements. Glass and Rock Mineral Wool product are easier to install than other insulation materials such as rigid boards as their flexibility allows them to adapt to any slight imperfections in the substrate and knit together, eliminating any air gaps. Evidence shows the absence of air gaps is crucial to achieving a high-quality thermal performance.
The Frametherm 38 slab is available in size 570mm by 1170mm to suit spacing commonly used in timber frame applications. The slab provides the best thermal conductivity in the range of just 0.038W/mK. FrameTherm slabs are easily cut to size if necessary, using a sharp blade such as a Stanley knife. A heavy ruler or plank of wood can be used to hold the slab as its being cut, and a mat is recommended to ensure the floor or surface is not scratched when cutting.
Earthwool FrameTherm Rolls and Slabs offer negligible resistance to the passage of water vapour and have a water vapour resistivity of 5.00 MNs/g.m. whilst the frametherm slabs cannot completely soundproof a space they provide excellent sound absorption characteristics.
ECOSE Technology is an innovative, new, formaldehyde free binder technology, centred on rapidly renewable materials instead of petro-based chemicals. It lessens embodied energy and
provides superior environmental sustainability. ECOSE Technology was developed for glass and
rock mineral wool insulation, but offers the same potential advantages to other products where resin-substitution would be an advantage, such as in wood-based panels, abrasives and friction materials.
Knauf FrameTherm Slabs can be installed in a range of methods. These methods include:
- Timber frame applications – between studs and rafters
- Pitched Roofs – at rafter level

How to insulate a pitched roof at rafter level
- Protective gear such as protective overalls, goggles, face masks, and gloves are recommended to prevent irritation caused by the frametherm material.
- Make sure the space is clear and tidy to prevent hazards. Outlets such as electrical sockets and openings such as windows should be taken into consideration before the insulation process begins.
Measure the widths between the rafters and match the thickness of the rafters with the slabs of insulation material being applied which is typically a depth of 90mm or 140mm. Measure the length of the timber frame wall to work out the number of slabs that need to be applied and cut slabs where necessary using a sharp blade to fit smaller spaces.
The frametherm slabs can then be firmly but carefully pushed into place, making sure all the edges are in place and secure without flattening the material as this will affect the performance of the slabs. Make sure any slabs being joint together are tightly butted to avoid thermal bridging.
Threaded suspension rods should then be fitted spaced 600mm apart along the rafters using a screwdriver and required accessory.
Frametherm slabs should then be laid horizontally over the top of the rafters and previously installed slabs. The slabs should match the depth of the timber purlins. The suspension clips should be fastened immediately into the existing rods to keep the slabs in place.
Fix metal angels on the wall just between the purlins. Attach metal furring profiles to the existing suspension clips. Apply two sides adhesive tape to the metal profiles. Release the foil from the other side of the tape. Apply a vapour control layer vertically across the metal profiles ensuring it is bonded to the double-sided tape. Apply the required adhesive and tape at the joints of the vapour control layer.
Plasterboard can then be measured, cut, and applied over the existing frametherm slabs and applied securely to the rafters using the required fixings. Trim overlength of vapour control layer from around the plasterboards.
