Sun room price
Detailed explanation of sun room price: cost composition, market range, influencing factors and quotation A complete guide to pit avoidance
(The completed real picture of the aluminum glass sun room on the broken bridge on the terrace, the overall facade of the flat-top sun room)
When many owners are preparing to build a sun room, the first question is how much a sun room costs per square meter. The unit price of sun rooms on the market spans a lot, from a few hundred yuan to two or three thousand yuan per square meter. Many people only look at the unit price when comparing prices, ignore the configuration differences, and finally have problems such as serious budget overruns, water leakage, and unstable structure. Sun rooms are customized envelope structures, and there is no unified fixed unit price. They are not standardized finished products. The price is determined by a number of factors such as frame profiles, top shape, glass configuration, hardware waterproofing, additional functions, and on-site construction conditions.
Many merchants drain at low prices, and the quotation only includes the basic frame and fixed glass. Opening windows, gutter falling water, waterproof closing, and hoisting reinforcement are listed as additions separately, which is also a very common routine in the industry. This article explains from multiple angles from the cost of sun room dismantling, market conditions, price influencing factors, price differences of different configurations, hidden charges, price comparison methods, and pit avoidance points, taking into account home improvement owners, decoration persons in charge, and door and window dealers

0、Sun room shape price list
First, compare item by item according to the shape
form
Second, the starting price comparison of different shapes (factory basic model caliber)
The quotation diameter of the basic model (main beam 3.0mm wall thickness + tempered glass) of the Foshan source factory can be used as an intuitive reference for the shape price difference:
Flat-top sun room: from 408 yuan/m2
Inclined roof sun room: from 458 yuan/m2
Curved sun room: from 588 yuan/m2
European-style (modeling) sun room: from 688 yuan/m2
可见造型越复杂，起步价越高：平顶 ＜ 斜顶 ＜ 弧形 ＜ 钻石/欧式造型。带玻璃升级（中空 +60、Low-E 中空 +80、夹胶 +120 元/㎡）和电动天窗、遮阳系统后，总价会进一步上浮。
Third, the overall price corresponding to the profile grade (contract labor and materials)
form
IV. Items that are easy to "add extra money" (the quotation must be checked)
Glass upgrade
Low-E, thickened laminated glass, + 80~ 200 yuan/m2
Electric sunroof
: 1500~ 4000 yuan/fan (manual sunroof hundreds of yuan)
Shading system
: Electric canopy/built-in louvers, 800~ 1500 yuan/m2
Waterproof process
: structural waterproof + drain + sealant, easy to glue cheap but short life
Aerial work/handling
: High-rise top floor hoisting, clearance, generally additional charges
Column reinforcement, ground foundation
Old house renovation is often single-column
Five, a few practical reminders
Area algorithm
: Industry multi-press
top projection area
Pricing, not the area of the facade windows, ask the caliber before signing the contract.
Less than 600 yuan/m2 all-inclusive
Be vigilant, mostly thin-walled/recycled aluminum + single glass, which is prone to deformation and leakage in three to five years.
Do not use single-layer tempered glass on the top surface
It is recommended to laminate the glue hollow (broken without splashing).
Rainy in the south/snowy in the north
Priority slope or herringbone top, the most stable drainage;
Diamond top, curved top
Although it looks good, there are many splicing seams, the risk of leakage is high, and the cost is more than double.Confirm before starting construction
Is the property/chengguan allowed to close the terrace?
Avoid illegal construction being demolished.
First, the pricing logic of the sun room: it is not simply one price per area
Most owners mistakenly believe that the total price is the direct area multiplied by the unit price of the sun room, which is the biggest misunderstanding in understanding the price of the sun room. The sun room is divided into five independent pricing plates: the top system, the facade door and window system, the structural reinforcement system, the drainage and waterproofing system, and the additional option. Different plates are calculated separately, and then the total price is combined.
Simple formula: total price of sun room = top surface (keel + top glass) cost + facade doors and windows (fixed glass + opening fan) cost + structural reinforcement, column, steel structure cost + gutter, falling water, sealing and waterproof accessories cost + manual installation, transportation and hoisting cost + sunroof, sunshade, intelligent and other optional costs.
Among them, the opening fan is a large premium, fixed glass is cheap, and the unit price of casement windows, lifting sliding doors, and folding doors will be much higher; electric skylights, built-in sunshades, and electric sliding tops are all separate price increases.
At the same time, the industry pricing is also divided into two modes: one is "the top surface is quoted separately, and the facade doors and windows are quoted separately"; the other is the package all-inclusive price. When comparing prices, be sure to confirm whether the scope of the two quotations is the same, and the numbers cannot be directly compared. For example, the price quoted by A merchant is 800 yuan/m2, which only includes the top fixed glass, and the price quoted by B merchant is 1000 yuan, which includes the top surface + fixed windows around. The two do not have comparative significance.

Second, the mainstream market price range of sun room (reference for labor and materials)
Combined with the domestic home improvement market, according to the configuration grade division, to give you a clear price range reference, only as a budget reference, the final site survey plan shall prevail.
Economy simple sun room: 600-1000 yuan/m2
Frame: ordinary non-broken bridge aluminum alloy or simple galvanized steel structure; glass: single-layer tempered glass, ordinary sunlight plate, color steel roof; sealing with ordinary PVC rubber strip, simple glue waterproof, no system drainage gutter; suitable for temporary storage, simple flower room, poor insulation and sound insulation, short service life, easy to seep water in rainy areas, not recommended for long-term leisure use.
Mid-end mainstream broken bridge aluminum sun room: 1000-1800 yuan/m2 (the most home improvement choices)
Frame: 6063-T5 broken bridge aluminum alloy, the wall thickness of the main force column is 1.8mm and above; the glass is standard with 5 + 12A + 5 hollow tempered glass, which can be upgraded to Low-E; EPDM EPDM sealing strip, supporting aluminum alloy gutter falling water, isobaric drainage structure; flat top, inclined top, conventional herringbone top shape; including basic waterproof, standard installation, suitable for terrace tea room, leisure area, taking into account cost performance, heat insulation and waterproof performance.
High-end system sun room: 1800-3000 yuan/m2 or more
The whole structure of the system sun room has been calculated by force, the profiles are thickened, multi-sealed, aluminum-wood composite, and the whole system is matched; the glass is made of laminated hollow, double Low-E, and three-layer hollow; diamond top, arc special-shaped top, and mobile sun room; with electric sunroof, intelligent sunshade, automatic closing of rain feeling, and strengthening of lightning protection nodes. It is commonly used in high-end gardens of villas, and the standards of wind pressure resistance, heat preservation, and waterproofing are higher.
Post script: Mobile telescopic sun room and photovoltaic sun room belong to special categories, and the unit price generally starts at 2500 yuan/m2, and the cost is much higher than that of fixed glass sun room.

Third, the frame profile: the core element of opening the price difference of the sun room
The frame keel is the load-bearing foundation of the sun room, accounting for 40% to 45% of the overall cost. The profile material, wall thickness, and whether the bridge is broken directly determine the price, safety, and thermal insulation performance.
Galvanized steel structure sun room: the lowest cost, strong load-bearing, suitable for large-span holes; the disadvantage is that steel is easy to rust, and anti-rust paint needs to be regularly brushed in the later stage, which has high anti-corrosion maintenance costs. Many low-cost sun rooms use square steel welded frames.
Ordinary non-broken bridge aluminum alloy: medium cost performance, corrosion resistance and no rust, but there is no heat insulation strip. In summer, the profiles are hot, the room is sultry, and the window frame is dew and dripping in winter. It is suitable for areas that do not require heat preservation.
Broken bridge aluminum alloy sun room (mainstream): The profile has built-in PA66GF25 nylon heat insulation strip, which cuts off cold and heat conduction, heat insulation and energy saving. Surface powder spraying and fluorocarbon spraying are optional. Fluorocarbon spraying has better weather resistance, and coastal rainy areas are preferred. The price is 15% -25% more expensive than ordinary powder spraying.
Aluminum-wood composite sun room: the outer aluminum material is wind and rain resistant, the inner solid wood, with high value and excellent thermal insulation, which belongs to the high-end solution. The profile cost is high and the price is the most expensive. Regular maintenance of the wood surface is required.
Key reminder: The main column and main beam of the sun room belong to the stressed rod, and the regular specification requires the wall thickness of the stressed profile to be ≥1.8mm. Many low-cost single profiles are 1.2mm and 1.4mm, which cannot be seen with the naked eye. There is a hidden danger of deformation in high winds and snow weather. The contract must state the profile series and measured wall thickness, and support caliper verification.

Fourth, glass configuration: affecting comfort and safety, each upgrade will increase the price
Glass accounts for about 30% of the cost of a sun room, and it is also the most overlooked part of the owner's price comparison. The same appearance is glass, but the internal configuration is different, resulting in a huge price difference.
Single-layer tempered glass: the cheapest, only meets the safety and splash protection, no heat insulation and sound insulation, and heats up quickly in summer, only suitable for temporary simple sun rooms.
Ordinary hollow tempered glass (5 + 12A + 5): standard at the middle end, the hollow layer isolates heat and reduces noise, meeting the needs of most family leisure sun rooms.
Low-E low-radiation insulating glass: Low-E film is added on the hollow basis to block infrared radiation, block outdoor heat from entering in summer, and lock the indoor heating in winter. The insulation effect is significantly improved, and the cost per square meter of glass increases by 100-200 yuan. It is highly recommended for west-facing and south-facing terraces.
Laminated insulating glass: two layers of glass are laminated in the middle, and the glass will not fall off as a whole. High-altitude, street-facing, and high-traffic positions are preferred, and the noise reduction ability is strong, but the price is higher.
Three-layer hollow, laminated hollow composite glass: sound insulation and heat insulation full, suitable for elevated, cold areas, the cost of floating significantly.
At the same time, the glass warm edge strip is also a detail. Ordinary aluminum spacers are prone to cold bridge condensation. Upgrading the warm edge strip will also increase the cost. Low-cost orders often omit the warm edge strip.

Fifth, the top shape: different top types have different process difficulties, and the price increases step by step
The sun roof type directly affects the processing difficulty, material loss, and labor hours. The price order is roughly: flat top/inclined top < herringbone top < diamond top < arc special-shaped top, combined top.
Flat-roofed sun room: with the least materials, simple cutting, low processing and installation difficulty, the highest cost performance, and the most available on the market; the disadvantage is that the drainage slope is limited, the slope design is not in place, and it is easy to accumulate water, which requires high gutter drainage system.
Herringbone top sun room: two-way inclined surface, smooth drainage, friendly rain and snow areas, atmospheric shape, keel materials are more than flat top, and the unit price rises by 10% -20%.
Diamond top sun room: multi-bevel splicing, multiple cutting angles, large profile loss, complex assembly process, high value, soft lighting, belongs to mid-to-high-end shape, and the price is higher than the herringbone top.
Arc top, arc-shaped sun room: profiles need to be bent and processed, with high equipment and process thresholds, great losses, and the highest cost. They are generally only used for villa customization solutions.
Many merchants offer the same type of profile, with a flat top of 1200 and a diamond top of 1600. The price difference mainly comes from processing labor and material loss, not the upgrade of the profile itself.

6. Waterproofing, gutter falling water, sealing accessories, it looks inconspicuous, the price difference and hidden dangers are here
Many low-priced quotations only count frames and glass, aluminum alloy gutters, downspouts, weather-resistant sealants, waterproof flanging, and waterproof joints with walls are all charged separately. This is the most common addition routine.
A complete sun room drainage system includes thickened aluminum alloy gutters, downspouts, PVC or aluminum alloy downspouts, and expansion joints; high-quality gutters will be heightened and deepened, and rainstorms are not easy to overflow.
The gap between sealing materials is huge: the regular sun room uses neutral silicone weathering glue and structural glue, and the quality assurance period is long; the low-cost single use of inferior glue, 1-2 years of cracking and degumming, rainwater seeps into the room along the gap, and the later maintenance cost far exceeds the original price difference.
Wall handover position, the regular practice is to do waterproof flanging, waterproof membrane additional layer, and then with sealant, floodboard; many guerrillas directly apply a layer of glue to deal with, short-term leakage, concentrated water seepage in the rainy season.
Accessories, waterproofing, and falling water systems do not seem to be large. A set of more than ten square meters of sun rooms often costs several thousand yuan. When comparing prices, be sure to confirm whether the quotation includes a complete set of drainage and waterproofing systems.

7. Additional optional items: increase on demand, each item will increase the total price
In addition to the basic frame and glass, many functional accessories are individually selected, and they are also the hardest hit areas for budget overruns. Please understand the unit price in advance:
Electric lighting and smoke exhaust skylights: a single fan ranges from a few hundred to thousands of yuan, including window openers, wind and rain sensors, and control switches. The total price of multiple skylights can easily increase by several thousand;
Shading system: external electric shading, built-in honeycomb curtain, canopy shading, rigid demand for west sun room, priced according to top area;
Open doors and windows: Lifting sliding doors, folding doors, and casement windows is much more expensive than fixed glass; matching screen windows are also optional;
Reinforcement project: The original wall bearing capacity is insufficient, and independent steel structure bases and load-bearing columns are added, which are often required for high-altitude and long-span sun rooms.
High-altitude construction fee, hoisting fee: high-rise terrace, profiles, large glass elevators cannot be transported, crane hoisting, scaffolding, separate charges;
Demolition and removal: original old guardrail, old roof removal, construction waste removal.

Other external factors affecting the price of sun rooms
In addition to materials and styling, site conditions, geography, and procurement channels can also contribute to differences in quotations.
Regional labor: labor and hoisting costs are higher in first- and second-tier cities, and the same configuration is 100-200 yuan/m2 more expensive than third- and fourth-tier cities; the waterproof standard in rainy areas in the south is higher, and the profiles in coastal typhoon areas need to be strengthened to resist wind pressure, which increases the cost.
Procurement channels: direct supply from the source factory, eliminating the need for dealers and store subcontracting, and the overall price is 15% -30% lower than that of the store; the store includes design, after-sales, and store operating costs, and the quotation is higher, but the service docking is more convenient.
Area size: The unit price of a small-area sun room is usually more expensive because the fixed costs of measurement, equipment, and labor are allocated to a small number of square meters; for a large-area courtyard sun room, the unit price can be reduced.
Approval conditions: Some communities and terraces need to report plans for building sun rooms, and individual areas involve handling costs, which should also be considered in advance.
Nine, the sun room quotation high-frequency trap, price comparison must see
The unit price is only quoted on the top surface, excluding the facade doors and windows, and the facade will be increased at a high price separately in the later stage;
The quotation is all fixed glass by default, and the opening windows, skylights and screen windows are all increased separately, and the instructions are not actively explained in the early stage;
The wall thickness of the profile is vaguely marked, only the broken bridge aluminum is written, not the wall thickness and brand, and the thin-walled profile is replaced later;
Omit gutter falling water, strengthen waterproofing, and inform the need to upgrade waterproofing in the middle of construction, and charge extra;
The low price does not include hoisting, demolition, garbage removal, and a large amount of hoisting fees will be added in the later stage of high-rise construction;
Confuse "projected area" and "unfolded area", the diamond top and herringbone top are settled with unfolded area, and the area is inflated;
The quality assurance is vague, only one year glue is guaranteed, and the frame and structural glue of regular manufacturers generally give more than 5 years of quality assurance.
Correct price comparison method: The merchant is required to issue a detailed configuration list, marking the profile brand wall thickness, glass specifications, glue brand, top type, whether it contains gutter waterproofing, hoisting, dismantling, with node drawings, all written into the contract, the settlement method is agreed, and the verbal commitment is rejected.
(The detailed quotation list template of the sun room is indicated, and the configuration details are marked)
How to choose a cost-effective plan according to the budget
The budget is limited, priority is given to flat-top broken bridge aluminum + standard hollow Low-E glass, good gutter drainage, reduce special-shaped shapes, and do less opening fans to meet basic leisure flower growing;
Pursue comfortable tea room, long-term use, choose mid-end broken bridge herringbone top, standard Low-E insulating glass, reserve 1-2 electric skylights for ventilation, and install basic sunshade;
Villa high-end courtyard, the west sun is serious, the budget is sufficient to choose the system diamond top or mobile sun room, laminated insulating glass + a full set of intelligent sunshade rain sunroof, structural stress special project calculation.
It is not recommended to pursue the lowest price blindly. The sun room belongs to the outdoor envelope structure, which is extremely difficult to repair due to water leakage and structural deformation. The cost of later renovation is often much higher than the previous price difference.
Summary
The price of a sun room is not a simple number, it is the result of the joint determination of profiles, glass, modeling, drainage and waterproofing, hardware, and construction conditions. A simple sun room of a few hundred yuan, a mid-end broken bridge sun room of more than 1,000 yuan, and a high-end system sun room of more than 2,000 or 3,000 yuan correspond to completely different material standards, service life and use experience.
Many owners compare prices and step on pits. The root cause is that they only compare the unit price per square meter, ignore the range of quotation, and treat the low-priced order without gutter, opening, and waterproofing as an all-inclusive price. When inquiring, first clarify your needs: whether it is flower storage, or a daily leisure tea room, the floor, orientation, rain, snow and wind conditions where the house is located, and then let the merchant come up with a plan and list according to the unified standard Horizontal comparison.
To understand the cost logic of a sun room, it is not to keep the price down, but to know where every penny is spent, avoid the low-price increase routine, and choose a sun room plan that fits the budget, is safe and waterproof, and meets performance standards.
