GRP Warm Roof Installation Cornwall

GRP Warm Roof Installation Cornwall

GRP Warm Roof Cornwall

We install a GRP Warm Roof which complies fully with the Thermal Insulation regulation throughout Cornwall & Devon. GRP roofing is perfect for Garage roofs, Bay windows, Balconies and flat roofs.

Warm Deck – Insulation is placed on top of the rafters/joists and the roof covering is then placed over the insulation. No ventilation is required for these types of roofs.

Cold Deck – Insulation is placed between the joists/rafters or in between the ceiling joists in the case of a pitch roof. Ventilation is required for these roofs.

We can add a choice of Lanterns and skylights to any of these GRP roofs.
Modular Extensions Installers Cornwall & Devon

Modular Extensions Installers Cornwall & Devon


The modern way to extend your home is with a flat roof (GRP Warm Roof) extension. When we build warm roof rooms we choose the Ultrasky flat skylight which features a frameless contemporary design that will flood the room with natural light. Couple this with bifold or sliding patio doors and you create a lovely bright living space.

A Livinroof build has all the benefits of solid conservatory roofs and glass conservatory roofs. The Livinroof allows glazing to be added in any configuration and in any shape, best of both worlds!Achieving the build you want is easy with this flexible system that can be used to create a focal point in your new room that will help it stand out.

Ultraroof is our favourite! It is the ultimate extension with the thermal properties of brick or super-insulated columns (depending on your choice) and the ultimate in lightweight tiled roof solutions.
Due to the strength of the Ultraroof beautiful vaulted ceilings can be created without the need of a tiebar.

The Conservatory Base & Walls are usually installed on small strategically placed concrete pads which saves time, creates hardly any mess and reduces the stress involved when considering a new build conservatory, orangery or modular extension.

If you prefer a render finish that is possible with the use of Lekas unique external boarding, which can be rendered to directly.
Leka Xi – Faster Installation

Because a Leka Xi – Conservatory Base & Walls system is easy to install with no deep footings required a conservatory base or modular extension can be installed in days rather than the weeks it takes when using older building methods. Due to the lightweight GRP structure there is no moisture absorbed, no thermal bridging, no damp. The base and walls are both thermally efficient to building regulation standards.

The Leka Xi is precision ,engineered using unique modular sections that have been pre-fabricated and tested in the factory. Before delivery every single part of the Leka Xi is checked to make sure it is perfect.

Durabase Supply & Install

Durabase Supply & Install

The Durabase conservatory base is our prefered method of building bases and walls for our Conservatories, Orangeries and modular extensions throughout Cornwall & Devon. A Durabase creates absolutely no mess, unlike conventional building methods, the Durabase can be installed in a fraction of the time it takes to build a base using concrete blocks and facing with brick. The Durabase System features a steel base which is bolted together on site and fixed to the wall of your home using resin and anchor bolts. The base is made specifically for your build so it will be an exact fit. Durabase has so many positives compared to the old method of conservatory base building.
The Durabase once assembled will create a safe, strong and robust foundation for your building.
The only foundations needed from the Durabase feet are a number of concrete pads which will be concreted at specific points around the base. This is so much less excavation work and hardly any waste material to dispose of compared to other methods of base construction. The Durabase System is also super fast to install. An average base and wall can be installed in less than two days.

Testimonials

Mr B. Berry

St Austell, Cornwall

At first I was apprehensive about not going with one of the main brands, but after chatting with Tom from Best Glaze he put my mind at rest. We decided to have the whole house done in Timber windows as its a stone character building. The lads did a super job cutting the trims around the stone and my windows look fantastic.There was absolutley zero mess which we were pleased about and they cleaned down every day after themselves.

D. Goulter

We had Best Glaze install a conservatory with a warm roof along with all our windows and doors in the house. The whole process from start to finish was very smooth and the installation was fantastic. The attention to detail is outstanding, we couldnt be happier with the the service and the product. We cheekily asked if we could have a patio installed around the conservatory as an afterthought and the team worked late and on a weekend to lay it for us. They went above and beyond These people offer a personal touch with a thoughtful team that respects you and your home that clean up after themselves I would highly recommend Best Glaze.

We had Best Glaze Windows do our windows doors and we are very satisfied with the work that has been carried out we would recommend them to anyone

Hollie McKernan

St Austell, Cornwall

Best glaze were very professional. The installers produced a top quality finish with no cutting corners. They made sure their work area was neat and tidy by keeping tools and sharp objects safely on my property and in their work vehicle, which was very appreciated due to having young kids at home. The level of finish was nothing less than outstanding! I would definitely recommend them and if needed I would not hesitate in booking more work in with them again.

Jaine H

Launceston, Cornwall

The guys carried out an amazing job fitting our replacement uPVC windows and doors, having a converted barn I don't think we have a straight wall in the house, added to that the original windows had been "strapped" which increased the difficulty in removing them. Innovative ideas ensured that the new windows and doors fitted perfectly and looked "right".
The work was carried out with consideration to our home, ensuring that no damage was caused. The work was strategically planned with our input and Jay and Tom were always happy to work on in order to ensure the minimum of disruption to our lives and work areas were always left tidy.
I would have no hesitation in recommending them to anyone considering having work done.
