Penthouse Carpets: questions and answers
Penthouse makes British wool-rich carpet ranges including Carlton, Colorado and Crofter. They differ in fibre blend, pile weight and use category, so compare the named range and sample rather than applying one warranty or cleaning rule to the brand.
Is Penthouse Carlton 100% wool?
No. The listed Carlton pile is 80% wool, 10% nylon and 10% polyester meltbond.
Does Carlton come in multiple weights?
Yes. Penthouse lists 36 oz and 42 oz Carlton variants with different published tog values and use classifications.
How is Colorado different from Carlton?
The named blends and weights differ; Colorado contains polypropylene where Carlton includes nylon. Compare the full current sheets.
What is Crofter Loop?
It is a separate Penthouse product from the Crofter cut-pile range. Their pile construction and care requirements may differ.
Are Penthouse carpets available in 5 metres?
Carlton, Colorado and Crofter list 4 m and 5 m widths; confirm the exact shade and production batch.
Can I fit Penthouse carpet on stairs?
Confirm stair suitability for the selected carpet weight and plan tread, riser, winding, underlay and fixing in the quotation.
Can I bleach-clean wool-rich carpet?
Do not use bleach without explicit manufacturer instructions for the named range. Wool requires fibre-specific care.
Can I use Penthouse over underfloor heating?
Check the selected carpet’s stated tog plus the specific underlay’s tog against the heating-system limit.
