Entrance Door Installations in Sussex

PVCu

PVCu (unplasticised polyvinyl chloride) doors have good weather resistance, are highly durable and low maintenance. Made from a uPVC skin either side with a Styrofoam core for good insulation whilst being light in weight. PVCu doors can also be reinforced with steel for extra strength.


Choose from a huge range of options to create your own bespoke PVCu door, with various choices of style, frame, glass, colour and furniture. Also available with wood grain effect if you are wanting to keep a more traditional wooden style but with the benefits of modern PVCu materials.

How Do I Know If My Door Needs Replacing?


If you notice any draughts or leaks, visible warping or damage, higher energy bills, excessive noise coming in from outside or if you're having difficulty opening or locking - it might be time to think about looking for a new door.

Composite GRP

Composite doors are becoming increasingly popular, with a vast range of styles, colours, glass, finishes and frames available.



Composite doors are made by compressing multiple materials under high pressure. Typically with a solid timber inner frame and high insulation foam core surrounded by a glass reinforced plastic skin on either side, usually greater in thickness than a PVCu door skin. Composite doors are secure, durable and energy efficient due to the extra thickness and materials used to manufacture.


We offer clients only the best manufactured composite doors from Rockdoor, Palladio Doors, Apeer Doors and Fortrezz Doors.

Are New Doors More Energy Efficient?


Yes. Modern composite, uPVC, and aluminium doors are designed with insulated cores and multi-layer seals to significantly reduce heat loss and improve efficiency.

Hardwood

Give your home a timeless and traditional appearance with a hardwood entrance door. Choose from a range of styles, covering both traditional and modern aesthetics, and various colour options with a variety of door furniture.


Hardwood doors consist of a hardwood veneer face on either side of a solid hardwood core made from multiple layers of hardwood. Timber is a natural insulator so retains heat well and hardwood is dense and hardwearing so is likely to last a long time. Although wooden doors may require greater maintenance than other materials to stay looking it's best and are typically more expensive.

How Secure are Modern Doors?


Our composite doors are manufactured for high security and strength. Composite doors are more secure than other materials due to the fibreglass reinforcements. Some doors are also built with a 10 point locking system and marine grade stainless steel components.

Bi-fold Doors

Open your home to give a better view of your garden, bringing improved light into the room whilst still providing excellent thermal efficiency. With a choice of opening configurations including opening at both ends, being stacked at one end when open or opening like a conventional door. Also available in an extensive choice of colours inside and outside. Available in PVC-u, aluminium and hardwood.


If you're looking for a bit more privacy, but would also still like the large opening of bifold doors, why not add integral blinds between the glass. These are built into the sealed unit so are completely dust free and low maintenance with opening operated magnetically or motorised.
