Material Information


Why choose uPVC?

uPVC patio doors are energy efficient, offering cost-effective thermal insulation, which will reduce your heating costs. Our uPVC patio doors can accept triple glazing.

KAT patio doors are competitively priced and offer exceptional lifetime value, with an operational life expectancy of 35+ years. They are 30% – 50% less expensive than timber or aluminium windows and therefore represent excellent value for money.

uPVC doors and windows are very low maintenance products and are extremely easy to care for. Cleaning is simple using soapy warm water.

uPVC is 100 % recyclable and our doors are typically more durable than timber and will therefore remain in situ longer, because they will not shrink, warp or rot.




With our wide range of exclusive designer doors we also offer you a complete range of accessories from handles, to threshold options, to opening configurations.

Our patio door handles are luxury products, made exclusively to a KAT design and crafted from Stainless Steel and are guaranteed for 10 years. Handles are available in White, Chrome, Satin, Gold, Grey and Black. Letterboxes are available in White, Polished Gold, Black or Chrome.

Please be aware of the handles available in the special offer prices.


Safety & Security


Our uPVC patio doors were designed to discourage intruders and are fitted with enhanced security locks. We know how important it is to keep your home secure.

All KAT uPVC patio doors are fitted with a 3 Star Diamond lock cylinder for your security. Our market leading patio doors also have integrated anti-lift systems so they cannot be lifted off the track from the outside, when in the locked position.
