We’ve put 28-years of door manufacturing expertise into the Spartan Door range. With more homeowners looking to save money on their heating bills and do their bit to help the environment, we’ve ensured that every door in the Spartan range has been created with energy efficiency in mind.
With Spartan energy efficient doors, you’ll benefit from:
Whilst windows are rated for energy efficiency in much the same way as household appliances and carry a ‘rainbow’ level with a staged rating, doors don’t yet have the same system.
The energy efficiency of a door is measured by U-values, which are used by builders to measure how effective a material is at insulating against heat loss. The lower the U-value the more energy efficient the material is.
With Spartan Doors, you can look to achieve U-values of up to 0.7 – which exceeds the very highest standards of energy efficiency ratings.
