How are Lienne Garden Offices constructed?

The Lienne Office is a contemporary design and will bring an impressive element to your garden. With large, double glazed windows and doors as standard you will not only have plenty of natural light flooding in, you will also be helping to reduce heat loss and condensation.

Equipped with Foil-Backed Polyurethane insulation in the Walls and an insulated Floor and Roof, this Office will provide and maintain temperature all year long (helping reduce those heating costs).

Using sustainably sourced, Pressure Treated timber/Spruce, your new Office will be protected against rot and insect infestation. Furthermore, the Lienne™ is built using modern methods of construction, providing quicker and safer self-assembly of your Office.

Why do we use PLASTERBOARD?

Simple – it is the only way you will end up with a wonderfully smooth plasterboard finish where all the joints have been taped and jointed, just as it would be in any new timber frame house. This means that the inside of your Office will not be sullied by crisscrossing trims trying to conceal the panel join seams or multiple polypin nail heads sprouting out of panels leaving you feeling like you are working in a glorified portakabin. This is why we are one of the VERY FEW Companies who will actually show you a close up of our Office interiors; see below to compare it to the alternative.


Consumers sometimes avoid the use of plasterboard through apprehension over the appearance of cracks. Our own 70mm x 35mm frames (these are finished sizes not nominal – nominal is the size prior to planing the timber and would be 75mm x 38mm), however, offer the appearance of a newly made timber framed house. You do not see cracks appearing in the boards of a newly made timber framed house, why should you see them in a similarly framed Garden Office? Plasterboard is a superior option to MDF, polyester vinyl coated plywood, or even Tongue & Groove timbers. Unlike the aforementioned, plasterboard is also fire resistant and gives thirty minutes of fire protection; the reasoning behind its use in houses. We have searched comprehensively to find other Companies offering a plasterboard finish and all of them are at least twice as expensive as our own Offices. We do it as we want to be the BEST!

What is the exterior made from?

We have not neglected consideration of the outside either. As standard, we Pressure Treat our Lienne Offices in our very own Pressure Treatment plant, leaving you with a Pressure Treated 16mm overlap finish and a 10 year warranty!

If you want an even longer lasting building then you can upgrade to Siberian Larch.

Siberian Larch is a fantastically durable and dense timber that is used in many marine applications, including boat building and piers. As anyone with experience in timber will tell you, wood that will last in water is timber that will last a very long time. We will guarantee this for 20 years in an untreated state, though we have heard of this timber lasting decades more.


How are your walls constructed?

Regardless of which external cladding you choose, your Lienne will still have one of the thickest walls available on the market today at 148mm thick! This is over 50% THICKER than our nearest Competitors. The cladding is braced and cross braced for strength, allowing any water to easily pool away from the building. The pre-fitted breather membrane enables the Office to ‘breathe’, whilst also preventing water penetration. Behind this there is a solid sheet of 10mm thick MFP board, specially chosen for its structural strength and stability, screwed to the 70mm thick framework. In between the frames there is one of the best insulating materials available.


How do you insulate the walls?

For wall INSULATION we use 70mm thick double backed polyurethane. Polyurethane is at least twice as efficient at retaining heat as its cheaper alternatives polystyrene or rock wool. A rigid material, it will not lead to uneven insulation, which is a common problem when rock wool is used as it drops down into the wall cavities.


How do you insulate the roof and floor?

For roof INSULATION, we use a unique Structurally Insulated Panel (SIP) with 10mm MFP and 50mm thick double backed Polyurethane insulation (60mm). We also use SIP construction for our floor insulation, which our Hungarian factory manufactures. This is a chemically bonded sandwich panel of 10mm MFP, 50mm double backed Polyurethane and then 10mm MFP, providing a 70mm thick insulated floor! These panels include wooden battens that add strength and align two panels when they join. To our knowledge we are the only Company to offer such a technically advanced flooring system which combines strength (the panels can span 1200mm meaning significantly less spot foundations – more on that later) and very high insulating qualities.
