PURe Window

PURe Window

The PURe® window range is a revolutionary new range of aluminium windows which uses an innovative, enhanced thermal barrier manufactured from expanded polyurethane (PUR) allowing ultra-low U-values to be achieved.

PURe® aluminium windows are fully compatible with Senior doors and curtain walling and are available pre-finished in an almost unlimited range of colours and finishes both inside and out.

With a generic Green Guide rating of ‘A’ for use in commercial projects and a life expectancy in excess of 40 years, the PURe® window range is 100% recyclable and has been designed to meet the Passivhaus standard.

Available Configurations:
  • Inward Opening Tilt/Turn
  • Open Out Casement (Top or Side-hung)
  • Weather Rating tested to BS 6375-1:2009 achieving 600Pa air permeability, 600Pa water tightness and 2400Pa wind resistance.
  • Able to receive double or triple glazing up to 50mm for maximum thermal and acoustic performance
  • U-Values as low as 0.71 W/m²K when calculated as a commercial CEN standard window

PURe® Frequently Asked Questions

How does PURe® achieve ultra-low U-values?

By means of an innovative thermal barrier manufactured from expanded polyurethane, with inherent insulation properties which ensure that heat loss is minimal, and overall U-Values are significantly reduced. When specified correctly the PURe® range can give Uw-Values as low as 0.71 W/m2K for commercial CEN Standard windows.

Where can PURe® windows be used?

Anywhere, from commercial to domestic, education to healthcare, new build, refurbishment or retro-fit. Wherever they are used, PURe® windows can improve CO2 calculation by up to 3% at minimal extra cost.

Do PURe® windows meet current legislation?

Yes - the PURe® range has been designed not only to meet current legislation but exceed it. It has also been designed to exceed future legislation.

Are PURe® windows environmentally sound?

Yes – PURe® windows are 100% recyclable - Aluminium is a cradle to cradle product which can be recycled endlessly. The thermal barrier would typically be re-used as fillers for other products, with no requirement for landfill. The PUR® thermal barrier is also free from Chlorofluorocarbons (CFC) and hydrochlorofluorocarbons (HCFC).

Can PURe® windows contribute to a credible BREEAM rating?

Yes - As BREEAM is a whole building evaluation, they can contribute significantly. Under the generic Green Guide, PURe® windows would typically be A rated in commercial use. Please contact us for assistance to maximise available BREEAM credits.

Is the PURe® thermal barrier as strong as Polyamide?

Yes - shear testing has been carried out in accordance with BS EN 14024:2004 and has consistently out-performed polyamide.

Are PURe® windows durable?

Yes – the PUR thermal barrier contains carbon black UV stabiliser to make it UV stable. Its closed cell construction prevents water absorption which means it will not rot and unlike wood the PUR barrier does not provide any 'food' for fungus and mould to grow. PURe® windows have a 25 year warranty, with an expected lifecycle in excess of 40 years.

Has the PURe® range been tested?

Yes, PURe® has been tested to relevant UK and European Standards for Shear strength, air permeability, water tightness and wind resistance.

How good is acoustic performance?

The PURe® range of windows benefit from glazing options to 50mm to allow enhanced acoustic performance.

How much does PURe® cost?

The PURe® range is competitively priced – no other aluminium system currently available beats our price for the performance. Even better because of the simplicity of manufacture, fabrication time is reduced, lowering comparative costs still further.

Is the PUR thermal barrier safe?

Yes - PUR has been has been tried and tested and used in the construction industry for many years (typically in cladding and insulation products). It is non-toxic, making it safe to handle and manufacture. PUR is non -flammable, has a Class '0' fire rating, does not give off toxic gases when burned and does not give off Volatile Organic Compounds (VOC) in use.

Is additional tooling needed for manufacture?

No - normal tooling used in the construction of aluminium windows will be sufficient.

Is special hardware needed?

No - the system is designed to incorporate the usual hardware and fittings (friction hinges, handles, espags, shoot bolts etc.) so no additional training or tooling is required.

Is the system available in all standard finishes?

Yes - all sections are supplied pre-finished, either polyester powder coated or anodised. There are no surcharges for dual colour.
