SuperFOIL & Polyethelene DPC

SuperFOIL & Polyethylene DPC

We were recently asked how SFUF stacked up against a typical Polyethylene DPC. The first difference is that SFUF is a reflective insulation while DPC is not; it’s a damp proof membrane.

SFUF contains layers of high performance laminated foil materials. In particular SFUF includes two layers of SFTV, SuperFOILs high performance fully woven foil material which is both waterproof, water vapour (VCL) and CE certified.

Our technicians compared performance testing to EN standards for both products and found that the materials in SFUF are as waterproof as any typical PE DPM. Right-click and “save as” here for a comparison of performance standards (spreadsheet in .xls format).

SFTV is W1 waterproof (which is the high standard of waterproofing). A 1200 gauge PE DPS is also W1 waterproof. You may see products that are labelled waterproof, but if they are not labelled W1 then they may be W2 or even W3 a lower performance. A W2 or W3 labelled product may only be considered shower proof or waterproof when protected (e.g. like a material that can be used only in the cavity of a cavity wall).

W1 is the standard needed for use on a roof as it will withstand driving rain, if a material is not stated as being able to be used on roofs it may be W2 or W3.

What about water vapour permeability?

The laminated fully woven aluminium foils that make up SFTV are also impermeable to water vapour, Polyethylene DPCs are not. PE is basically similar to material as a regular sandwich or freezer bag, just much thicker in a DPC.

PE does not create a barrier like a layer of aluminium metal can and with PE osmosis will occur. Where there is water pressure differential water will “pass” which is why DPCs are only used to tackle capillary action damp and they are not used where there is standing water.

SFTV is a fully woven construction, it’s much stronger than Polyethylene and does not stretch like a PE material. SFUF has the benefit that it has not 1 but 2 layers of SFTV and there are protective layers of foam and secondary thinner foil layers that provide additional performance protection. The SFTV material in SFUF has comparable performance to typical 1200 gauge PE DPMs

SFTV has passed the same European Standard as a DPC; EN1928 (the standard of waterproof performance) and is W1 waterproof. In EN standard testing SFTV is superior in strength and vapour control.

We hope this little article helps you appreciate how SFUF makes your important construction projects better.

SF40 The Versatile Insulation

SF40 The Versatile Insulation

Paul wanted a good level of insulation in the new extension to his home that he is self building. He is installing underfloor heating, and it’s a difficult combination of new and old. Part of it will be the original house and part of it the new extension. Therefore he wanted to be sure he had a high level of insulation under his underfloor heating pipes and it had to be flexible and easy to adapt.

He also wanted to make most of reflecting the underfloor radiant heat upwards into the home, the radiant barrier that SF40 provides and the air tightness are additional benefits.

SuperFOIL SF40 for UnderFloor applications

The solution; Paul fitted SF40 over his joists, with the Underfloor heating pipe over the SF40. Then he fitted battens to lay the floor on. Now he has a well insulated floor that is air tight and has a radiant barrier. The flexibility of the material made it easy to install and minimised any waste.

Zagreb SuperFOIL Installation

One enthusiastic SuperFOIL customer in Zagreb Croatia sent this photo of his SuperFOIL SF19 install. Our experience is Eastern European countries are keen to take advantage technical advancements. This application was SF19, but the worlds highest performance multifoil insulation SF60 and our double performance SF40 are very popular in the east of Europe.

While regulations in Zagreb don’t require the standards that are the norm in the UK people are keen to leap frog from old technology to new technology to get the benefits that technology brings:

  • high performance insulation
  • radiant barrier
  • air tightness

which combine to give exceptionally low energy use.

Lofts – Cash Converters

Lofts – Cash Converters

With Loft converters worried about the rising cost of foam board and the new building regulations. SuperFOIL were asked by one of the countries leading Loft Converters to work out savings using SuperFOIL solutions.

On a comparison of materials SuperFOIL is the most competitive every time. For the new building regulations those savings increase by up to 200%. When you also include the savings from less waste, speed of install, savings on manpower, reduced storage and transport and not forgetting the airtightness, vapour barrier and radiant barrier you can see why modern SuperFOIL solutions are better and more economical than traditional foam board solutions.

SFips Timber Frame Panel Production

SFips Timber Frame Panel Production

Our camera caught the action during production of the first SFips panels at a leading timber frame supplier. SFips are the insulation industries latest development to meet the new 2014 regulations coming in this month.

SFips, is short for Superfoil Insulated Panel System, SFips meet the new 2014 thermal performance standards by factory fitting 1 single layer of the worlds highest performance multifoil insulation.

The benefit of SFips timber frame panels are that the construction is factory controlled, giving a high precision, high performance timber frame that can be significantly slimmer than the majority of glass wool or foam board panels.

Walls thickness has grown a lot as thermal performance regulations have become tougher, with walls often in excess of 350mm thick. Thinner walls give home owners more floor space for the same price, or allow better development of a site as less site area has to devoted to the walls. In a tight site with multiple dwellings the wall savings can even result in space for extra rooms or even an entire dwelling.

SFips are economical on materials as well as manpower, with less timber, less waste, less cutting and less storage. SFips factory based production is not affected by the weather. Factory made SFips guarantee efficiency in every aspect.

SFips Timber frame panels are transported to site already insulated, as well as water and air tight complete with a radiant barrier, reducing construction time even further. SFips provide a ready made service cavity and all services are contained with in the warm envelope which not only protects them from the cold but ensure there are no penetrations that can affect air tightness and reduce thermal performance.

Cold weather, is it a sticky issue for you?

Cold weather, is it a sticky issue for you?

Cold Weather Tape

Superfoil has both standard tape and a high performance cold weather tape, using tape on insulation reduces the passage of air and improves efficiency. It’s always recommended that you “seal” when insulating to reduce or eliminate any passage of air.

Superfoil cold weather tape is a higher performance tape and makes the task easy and efficient. A customer called Vincent had the following to say:

This tape is infinitely better than the previous foil. Sticks just as well, but is much easier to apply and use. Many thanks

Ask for Superfoil Cold Weather tape when specifying, it’s 100mm wide by 40m long.

Ensuring a good performance on a barn conversion is a detail that needs a lot of attention. Barn converter Andrew saw the benefits of SF40, including the flexibility, high performance and easy to achieve air tightness, without the drawbacks of thermal bridging when using board between timbers (even in an existing building that can have its own peculiarities of construction).

SF40 in 2 layers provides solutions to around the U0.13 level of efficiency.
