Product Overview

Our StockFold range has now been updated and improved for 2024. This range is now called VariFold and offers a much superior product range. The VariFold range offers a fantastic product at great prices. So what is the difference between our CustomFold and VariFold product range?

Our VariFold Range

VariFold is exactly the same as our bespoke CustomFold range with some subtle limitations.

The VariFold range simply uses a scope of sizes for each product. This allows us to provide price guides for each system providing our customers with a transparent pricing structure.

The improvement from our StockFold range is that we no longer use stock doors. We only use our own doors and as such can make them to any size, meaning any size of system in the scope of the product is possible.

For example.

A 4 leaf StockFold system could be supplied in the following sizes 2858 x 2095 or 3162 x 2095 or 3466 x 2095. Our new VariFold 4T range can be any size between 2500mm and 3300mm wide by up to 2200mm high.

VariFold and CustomFold Differences

  • Cheaper Hardware??? NO. Our VariFold range uses the same high quality Stainless Steel hardware as our bespoke CustomFold range. Unlike many stock bi fold products available that use chrome hardware, our hardware is guaranteed for 10 years even in coastal areas. We also still use our hybrid aluminium self draining sill, or if you prefer a solid hardwood sill with our unique integrated drainage channel.
  • Door thicknesses are limited to 54-60mm on our VariFold range.

Benefits Of A Timber Product

  • Timber products offer better thermal insulation than PVCu and Aluminium.
  • More choice of finishes than PVCu and Aluminium with the added choice to change throughout the lifetime of the product.
  • Timber products do not rely on the glass units to keep them square and solid reducing the risk of unit breakdown.
  • Its very easy to repair and refinish timber products if accidental damage does occur.
  • Timbers used for our products are from sustainable sources and FSC approved.

Door Construction

Our doors are manufactured to a 44- 64mm finish.

StockFold doors are usually 44mm thick allowing for a 4:6:4 double glazed unit. These doors still meet part L building regulations but are not as thermally insulative as our thicker doors.

InternaFold doors vary from 44mm to 64mm depending on the usage. 44mm thick doors are used if solid panels or single toughened safety glass is required. 54mm thick doors are used when standard double glazed units are required. 64mm thick doors are used when integrated blinds or triple glazing is specified.

Glass Options

Single, Double & Triple glazing options available to suit all applications. Featuring Low e coated glass and Argon or Krypton gas to offer the best insulating properties possible. Safety toughened or laminated also available and standard on all door systems to meet building regulations.

Self Draining Aluminium Sill

All our External Bi Folding Door Systems utilise our self draining aluminium sill.

The 93HS Self Draining Sill is the perfect complement to our exterior folding door systems. It has been designed to integrate seamlessly with Brio Weatherfold 4s exterior folding door hardware. The aluminium tread makes it ideally suited to high traffic areas and high moisture environments. Mechanically fastened aluminium end caps feature a closed cell foam gasket to prevent water leakage. Water drains from the channel through predrilled drainage holes at the front of the sill.

Integrated Blind IGU’s

The Only True Solution For Bi Folding Doors & Windows!
Our Pleated & Venetian integral blinds ensure the insulating properties of the double glazing unit are maintained, while providing protection from dirt and weather conditions. The blind mechanism is totally encapsulated within the unit so here is no added risk of the unit breaking down.

Calculated U Values

The U-value assesses the rate of heat loss / gain through all the thicknesses of the combined elements that make up a building component such as a window, door, roof etc. It is a way of measuring the insulating properties of the building element. The lower the U-value, the better insulated the building element is. So a window with a low U-value should prevent heat loss / gain better than a window with a high U-value. We can provide U Value Certificates with all our door and window systems if you require them. Read more for further information and too see a sample certificate from one of our window systems.

Integrated Pleated Fly Screen

The 612 Retractable Pleated Insect Screen offers a screening solution all our door applications due to its innovative design. Developed by Brio for flexibility and tested vigorously for durability, the 612 Screen is a popular product worldwide. With our climate ever changing, the fly screen is becoming more and more popular in the UK.
